FOREWORD


Divers missions sent to the United States by the Allied armies are now
giving the benefit of their practical experience to the American army.
These missions are imparting to the officers of every arm the knowledge
of the details it is necessary for them to acquire.

The purpose of this book is to show to the American officers, and also
to the civilians who take an interest in war matters, how a large army
on the European Front in the last quarter of the year 1917 is made up.

In the course of general considerations we have explained what is meant
by the words “strategy and tactics”; we have described those interior
lines which have been of such powerful assistance to Germany; we have
dwelt on the composition of the large units of an army, and more
especially on that of a division as a fighting unit.

We have next examined the question of the command, and we have
attempted to define its duties as well as those of the staffs.

We have then devoted special chapters to the study of Aviation, the
Field Fortifications, the Artillery, the Supply of Munitions, and the
Infantry.

It is not at random that we have placed the various topics in this
sequence. It will facilitate the comprehension of the last chapter, in
which we describe, with examples, how an attack is to be prepared and
by what means its success can be assured.

We have deemed proper to close with a few remarks on the discreditable
means of warfare employed by the Germans: they have played too great a
part in important operations not to be mentioned.

Our readers will understand the reason why in certain instances we have
merely alluded to possible impending improvements of some parts of the
armament, without going into details which could not be given without
danger.

The few examples we cite have been selected with due consideration. We
have either personally played a part in them or they have been supplied
to us by officers whom we trust implicitly.

The perusal of this book will enable those who have sons in the
European armies to follow them more intelligently through the
operations in which they will soon take part, for we are in a position
to state that the United States Government has, for the formation of
the American army, adopted the figures which experience has taught
France to decide upon. Consequently what we say of the French and even
of the British forces will apply to the American armies.

The Making of a Modern Army




SYNOPSIS OF THE PRINCIPAL MILITARY OPERATIONS OF THE ALLIES ON THE
WESTERN FRONT


It has often been said that after the battle of the Marne the Germans
were virtually beaten. The feats of the German armies since that day on
such numerous and varied fields, the strength that they have so often
been proven to possess, prevent us from concurring in that opinion.

We believe that their defeat will be due to the accumulation of the
mistakes they have made.

In September, 1914, their superiority in numbers and in armament was
considerable. Their armies were holding in France positions that
enabled them, after a rapid reorganization, to assume a new and
vigorous offensive against the French Army, their sole adversary at
that time in the West.

The inconceivable pride of the German military party had encouraged it
to despise the enemy, and to blindly undertake that formidable rush
through Belgium for the capture of Paris. This dream vanished under the
blows struck by General Joffre and his marvellously responsive armies.

Her hatred for England in the first place, and in the second, her
thirst for conquest, were about to lead Germany to commit serious
blunders, and to lose the prize by grasping at its shadow.

To prevent the mobilization of the British armies, the Kaiser, after
entrenching his forces on the French Front, sent all the troops he
could dispose of against Calais. He felt so sure of success that he
followed the operations in person, ready to enter as a conqueror into
the city he expected to capture. He had acted in the same way two
months before at Nancy; and having failed in that effort, he was eager
for revenge.

The French, British, and Belgian armies took care to transform his
cherished revenge into a pitiful defeat.

It was then that the German Command committed the mistake which will
cause Germany to lose the war.

Leaving the Western Front, giving to the French and British armies time
to reorganize, arm, and gather strength, the Germans, having lost all
hope of achieving the dreamed-of victories in the West, hurled their
legions upon Russia, which they knew was insufficiently prepared, and
began that campaign which was to result in their capture of Poland and
the Baltic provinces, and the recovery of Galicia.

The consequences of the adoption of this new plan were to be seen at
once.

At the beginning of the summer of 1915, in Artois, the French and
British commenced to strike blows which proved that the strongest
system of field fortifications can be taken.

In September, 1915, General Pétain, in Champagne, inflicted a terrible
defeat upon the Germans. This operation, carried out simultaneously
with one in Artois, cost them thirty thousand prisoners, one hundred
and fifty guns, heavy casualties, and--which is even of greater
importance--obliged them to abandon highly valued and strongly
fortified positions.

In the beginning of 1916, having fulfilled their program in Russia,
the German General Staff resolved to finish with the Western Front, and
attacked Verdun with such enormous forces of artillery and infantry as
had never before been known.

Everywhere in Germany the announcement was made that the assault and
capture of Verdun would bring the war to an end.

Every one knows how vastly they were deceived. The French, taken by
surprise and shaken at first, rallied rapidly. During five months they
contested the ground inch by inch with a tenacity and heroism that
stamps the defence of Verdun as the most sublime military feat recorded
by History. The Germans did not take the fortress-city, but sacrificed
in their attempt the very flower of their armies.

Verdun had not exhausted all the strength of the French armies. On
the first day of June, 1916, on the Somme, General Foch attacked the
Germans so furiously that they had to suspend entirely their offensive
against Verdun.

On July 1st, the British Army, which had been developing to its final
form and efficiency, took its place on the left of the positions
of General Foch, and from that time on the Germans were forced to
transfer most of their effectives to the Somme and the Aisne in order
to oppose the Franco-British advance.

The fight begun in these regions in the summer of 1916 has continued
until now with scarcely any interruption. Slowly but surely the
Franco-British have driven the Germans from all the positions they
considered impregnable. They will continue by this method to push them
back into Germany.

The French armies on the left and on the centre undertook in the spring
of 1917 some very large operations on the Aisne and in Champagne,
which have given them possession of dominating positions, such as
the “Chemin des Dames” on the Aisne, and the hills of “Cormillet,”
“Teton,” “Monhaut,” and “Mont-sans-nom” in Champagne, which will be of
great value for future offensives. The capture of those hills, which
the Germans had proclaimed _impregnable_, followed naturally upon
the successes gained in 1915 by the Army of General Pétain, and were
completed by numerous smaller operations too long to enumerate here.

On the Aisne the advance of the French has not been delayed by the
famous Hindenburg retreat. From the very beginning the Germans have
accustomed us to the most astounding bluffs, intended more to blind
their compatriots than to frighten their adversaries, but the famous
letter in which the Kaiser complimented Hindenburg on his “masterly
retreat” (_retraite géniale_) is certainly the most stupendous bluff on
record.

Let us, Allies, pray God that the old Prussian Marshal may often be
afflicted with such masterly ideas! These should certainly take us to
Berlin.

For the purpose of recapturing the Chemin des Dames, the Germans have
recommenced on the Aisne a series of those reiterated attacks in
mass-formation which had cost them so dear at Verdun in 1916, and which
are now no less costly and unsuccessful.


THE MILITARY SITUATION IN OCTOBER, 1917

Two great facts dominate the situation to-day.

1st. The great success won at Verdun in August, 1917, by the French,
who in two days retook the positions that had cost the Germans five
months of ceaseless assault and enormous losses in men and material.
It is indeed a most remarkable success, considering that the German
General Staff, in the defence of the ground so hardly won, employed
every means known to military science.

The last battle of Verdun evidences the superiority that the French
artillery has gained over the German artillery.

2d. The recent victories of the British Army and those of the French
Army under General Anthoine in Flanders. Both French and British
have made continuous progress despite most unfavorable weather
conditions--fog, rain, and deep mud. The lines of communication of the
Germans with the Belgian coast are threatened, and the occupation of
the Belgian coast by the Allies will put an end to the hopes Germany
has based upon her submarine warfare.

The significant feature of these latest French and British victories
is the fact that the German armies now find it impossible to react
in time--or, in other words, to check an assault by launching prompt
counter-attacks.

The difficulty that the two Crown Princes experience in finding
immediately and on the moment troops sufficient for energetic attack,
proves:

1st. That notwithstanding the withdrawal of various contingents from
the Russian Front, they are short of reserves;

2d. That the quality and the morale of their troops have declined,
which is also evidenced by the large number and inferior fighting-value
of the prisoners taken.

These are signs which foreshadow not only the final victory, which is
not doubtful, but even a more rapid termination of the war than could
have been anticipated six months ago.

While the approaching entry of the American armies into the fighting
lines will be, from the start, of great importance for the military
situation, the participation of the United States in the war has
already produced in Germany a moral effect that the German authorities
are vainly trying to conceal. The number of the adversaries of the
military power increases every day, and even Prussian brutality is
powerless to prevent the diffusion of the idea that the leaders of
the Empire have terribly blundered in turning the whole world against
Germany.

Germany suffers much, and her sufferings can but increase, owing to the
insufficiency of the harvest in Europe.

Let us remember the prediction of a man who knows Germany well, the
former Representative from Alsace in the Reichstag, Father Weterlé.
“After her defeat,” he said in 1915, “Germany will astonish the world
by her cowardice.”

May his prediction prove true!

       *       *       *       *       *

We will now consider the general principles of the French military
organization, which are based upon experience dearly bought during the
past three years of war.

The American armies will be constituted upon a similar plan.




CHAPTER I

WAR PRINCIPLES

(For 1917)

  1. The rules of strategy and tactics have not been modified. The
       mode of fighting alone is different.

  2. Violation of the laws of warfare. Influence of science.

  3. Fighting units. The Army. The Army Corps. The Division. The
       Command. The Staff.


=1. Strategy and tactics are unchanged.= _Strategy_ is the art of
manœuvring large armies over a great extent of country.

_Tactics_ is the art of handling the troops on the battlefield.

One might be inclined to believe that, in the present war and since the
victory of the Marne, the general rules of strategy and tactics have
been modified. Not at all. The ways of fighting and the armament only
have undergone a transformation.

The opposing lines have buried themselves in mazes of entrenchment.
On both sides old methods of warfare and weapons forsaken or
forgotten for centuries have again been gradually resorted to. The
“Minenwerfers,” the trench guns, are nothing but the old-fashioned
mortar much improved upon. The jet of liquid fire driven by compressed
air, finds its prototypes in the Greek fire of Constantinople and the
hand-thrown combustibles--boiling oil and burning pitch--of the Middle
Ages.


STRATEGY. The rules of strategy remain immutable. They still consist
in attacking the enemy on one of his wings; in attempting to outflank
him on one side; in trying to cut his line in two by a blow in
the centre; in organizing a system of transportation so that the
necessary forces may be quickly assembled at the points which are to
be attacked or protected; in taking advantage of a superiority due to
the possession of well-organized interior lines. Such are the ancient
basic principles, that, in various combinations, have been applied by
contending armies since the dawn of military science.

_Examples._ When the Germans attacked on the Yser front, their purpose
was twofold: 1st. To outflank the left wing of the Franco-Anglo-Belgian
Army; 2d. To force their way towards Calais and Dunkirk so as to
prevent England from using those harbours for the concentration of her
armies in France.

After her failure on the Yser front, Germany made use of her
superiority in interior lines, composed of the railway lines existing
before the war, supplemented by new ones built as they were needed
for military operations. Owing to her central geographical position,
Germany is able at all times to dispatch forces from the heart of her
Empire to the various fronts; from Russia to the French Front, and
_vice versa_. To these interior lines is due the facility with which
she has quickly concentrated large masses of troops at any desired
point, notably on the Roumanian front at the end of 1916.

When she had firmly consolidated her Western Front she rapidly
collected all her available forces on the Eastern Front in an effort to
crush the Russians.

When, in February, 1916, the Germans launched the gigantic attack
against Verdun, it was with a twofold strategic purpose: 1st. To pierce
the French line between right wing and centre and resume the march on
Paris. 2d. In case of a partial success, to strengthen themselves by
the occupation of Verdun, with a view to preventing the French armies
from reaching the right bank of the Meuse, while at the same time
guarding their own left wing and their communications with Metz, should
circumstances ever force them to withdraw behind the Meuse.

During the autumn of 1915 the French attempted to avail themselves of
the comparative weakness of the Germans due to their campaign against
Russia. A favourable issue would have taken them to Vouziers-Rethel,
and very possibly have caused all the German lines to be withdrawn from
around Rheims and Soissons.

We might vary these examples. Quite recently, the British troops have
resumed the attack planned in 1915 by the French in Artois. They will
gradually free the North of France and Flanders.


TACTICS. Let us now consider tactical operations as they are conducted
on the battlefield. The formidable field entrenchments constructed by
the Germans have compelled both combatants to transform their artillery
and to change the armament of their infantry.

The manner in which the different arms are employed on the battlefield
has changed but little.

The field artillery has been enormously developed and it has been
necessary to constantly increase the power of the cannons and
howitzers. We shall later on discuss this subject more fully.

The definition of tactics as given by General Pétain, the French
Generalissimo, in the course of his lectures at the “École de Guerre”
has not been modified by the creation of these improved weapons. He
said: “The Artillery conquers the positions, the Infantry occupies
them.”

We will take for example a quite recent military feat which strikingly
establishes the distinction between the strategical and the tactical
operations.

On the 22d day of last October (1917), the French Army in the North,
east of Soissons, scored one of the most important successes of the
year. This operation, carried out on a nine-mile front, was essentially
tactical. It had for object the capture of very important positions
forming a salient in the French lines, which furnished the Germans with
facilities for an offensive return to Soissons. The capture by the
French of _Vaudesson-Allemant_ and the _Malmaison fort_ eliminated the
salient, opened the road to Laon, and exposed the German lines on the
Ailette to an enfilading fire.

This tactical operation was evidently a part of a vast strategical
plan matured by the French and British Commanders-in-Chief. The general
purpose of these operations aims at forcing the Germans to abandon the
North of Belgium and to retreat in France. All the tactical operations
being carried on in Flanders, on the Aisne, in Champagne and Lorraine,
are parts of this single plan and have the same object in view.

[Illustration: BATTLE FIELD OF THE FRENCH OFFENSIVE OF THE 22d OCTOBER,
1917.]

The rapid campaign just conducted by Marshal von Mackensen against the
Italians in the Julian Alps, like that he led in 1916 in the Dobrutcha
and Roumania, are evidences that the old principles of war, and
especially those practised by Napoleon, are still fully adhered to by
the German armies.


=2. Violation of the laws of warfare. Influence of science.= We must
acknowledge that, although the Germans had hoped in 1914 for a quick
victory gained by a few overwhelming blows, they had also, during their
forty-four years military preparation, provided for the possibility
of a check, and had equipped themselves with a mighty artillery which
enabled them to hold the Western Front while fighting against Russia.

France had to make great efforts to complete her armament in 1915.
Germany had already accomplished this in a great measure before the war
commenced.

It was reserved for German science, if not to render war more bloody
(the weapons used in 1914 sufficiently fulfilled this purpose), to
violate all the laws of warfare enacted by all the Governments, even by
the German Government itself.

German science has given birth to gigantic cannon which no law forbids
(we shall speak of these further on), but German science will bear,
in the judgment of History, the responsibility of having added to
the horrors of war an unprecedented ferocity and savagery by the
introduction of asphyxiating gases, tear-producing gases, and burning
liquids.

But we may add that Germany in her turn already suffers greatly herself
from her inventions; the Allies having been compelled to adopt and use
similar and often much improved weapons.


=3. Fighting units.= The fighting units are composed of a variable
number of tactical units. The tactical unit is the Division, the
composition of which will hereafter be described. It includes infantry,
cavalry, artillery, and engineers. It ought to possess also, and we
hope it will soon, a special service of aviation.

A group of two or three and sometimes four Divisions constitutes an
Army Corps. The union of three, four, or five Army Corps forms an
Army. In this war, two or three armies placed under one Command form
an Army Group. Four or five of these Army Groups exist on the French
Front. The general organization of the British differs but little from
that of the French armies. Whatever difference there may be exists
rather in the organization of the rear than in that of the front. The
British occupying a much shorter front, dispose of a proportionately
larger number of men. Though the bulk of their forces have been but a
short time in France, they have received from their women workers very
intelligent and valuable assistance, and, having at their disposal
larger appropriations of money, have been able to do much more than
France towards perfecting the organization at the rear.

The Army Corps and the Division must be organized so as to be entirely
and under all circumstances self-sufficient. They may, however, rely
upon any reserve forces that the surrounding armies may place at their
disposal, according to the work assigned to them.


A GLANCE AT THE NORMAL COMPOSITION OF A DIVISION

The real fighting unit is the Division. We purposely do not call it
a Division of infantry. The Division forms a whole by itself. It is
composed of all the different arms in the proportions that have been
deemed necessary to the efficiency of the whole body.

INFANTRY. Besides its Staff, which is the voice of the Command,
a Division normally includes two brigades of infantry of two
regiments each. The necessities of the present war have compelled the
belligerents to reduce to three regiments many of their Divisions, and
only the crack Divisions selected for attack have been kept up to four
regiments.

ARTILLERY. Each Division includes, under the command of a colonel:
1st. One regiment of field artillery with three groups, each of three
batteries each of four 75 mm. cannon;

2d. One regiment of heavy artillery with one group of 155 mm.
quick-firing cannon;

3d. One battery of trench guns, the number and the size of which vary.

ENGINEERS. A French Division includes one half battalion of sappers
and miners, which is not sufficient; two battalions at least ought to
be attached to it. The rapidity and solidity with which the German
entrenchments are constructed is due to the great number of engineer
battalions which our enemy possesses.

CAVALRY. A Division also includes two squadrons of cavalry. In the
trenches they are dismounted and used as connection-agents (_agents de
liaison_). Their duties will be considered at another point.

AVIATORS. A Division ought to possess its own aviation corps; planes
for reconnoitring, planes for directing the fire of artillery and the
movements of infantry, and swift battle-planes without the protection
of which all other flying-machines are exposed to great dangers.

We cannot insist enough on the necessity for the American Army to be
uncompromising concerning the perfect organization of its aviation.
Reasons which we lack space to discuss have so far prevented the French
section of aviation from having the complete general organization it
ought to have.

SUPPLY. All the services for the supply of munitions, and for the
repair and renewal of material, are centralized in a divisional Park.
To the supply of munitions we shall devote a special chapter.

The supply of provisions is entrusted in a Division to a sub-commissary
of stores. The Commissariat Department is part of the general service
at the Army base, and its study would lead us beyond the limits
assigned to this exposé.

MEDICAL DEPARTMENT. Every Division has its own medical department.
On this point, too, we shall abstain from entering into details.
Let us however remark that the medical service is still susceptible
of much improvement. In spite of continuous improvements in its
organization, in spite of the generous assistance of our Allies, of
neutral countries, and particularly of our American friends, the recent
engagements have proven:

1st. The insufficiency of the means at hand for rapidly collecting the
wounded on the battlefield;

2d. The insufficiency, near the battlefield, of large field hospitals
for the operations that cannot be delayed;

3d. The lack of special hospitals just out of range of the enemy’s
guns, where the severely wounded (_grands blessés_), and particularly
the abdominal cases, can remain as long as necessary. It is generally
acknowledged that those who have been wounded in the abdomen require
immediate surgical aid, and cannot be removed to a distance without
undue risk. Such dangerously injured men should therefore be provided
with “Rest hospitals,” where they can remain until able to be
transported to the base.

The transportation of the wounded should be the object of a very
close study. The trains for the transfer of the grave cases should be
further improved, their speed increased, and their appointments so
arranged as to allow the wounds to be dressed during the trip. Many
cases of gangrene would thus be avoided.

This is said without prejudice to the wonderful improvements which have
been made during the last three years. The devoted service rendered to
France by her military Medical Corps cannot be too highly praised.

American army surgeons, who have benefited by the vast experience and
wonderful skill of Dr. Alexis Carrel at the War Demonstration Hospital
in New York, will be able to do more for the relief of suffering and
the saving of life than their ablest French confrères could accomplish
three years ago.

THE COMMAND. The characteristic qualities of a “Chief” in the present
war must be:

1st. A very great physical endurance to render possible a great
activity. The General commanding a Division must actually see with
his own eyes every detail of the enemy’s positions. He must acquaint
himself with the nature of the ground occupied by his adversary as well
as with the strength of the latter’s defences. Such inspections will
often take him to the trenches, where his presence will keep up the
spirits of his men better than any exhortation written at a distance.

2d. The Chief must take in the situation at a glance. He must be
composed, and a man of prompt decision. Only on a thorough knowledge
of all the facts will he base his final dispositions for a fight. We
are of opinion that, especially in the present war, when a decision
has been taken or an order given, it is always advisable not to modify
these except in details of execution which cannot interfere with the
operation as a whole.

3d. During the battle, the Division General should establish his post
of command at a spot whence he may, if possible, see the ground where
his troops are engaged. He should, in any case, be where he can keep in
touch as long as possible with the generals or colonels of the infantry
under his command, and with his artillery and his information section.

4th. The Chief of any unit in war time is responsible for the physical
and moral condition of his troops. He will keep their spirit at a
high level if he proves to be as strict with himself as with his
subordinates. In all circumstances, he should treat them with justice
and kindness, but should be pitiless to bad soldiers.

He should by frequent personal inspections make sure that his troops
have good food, shoes, and clothing, and that their small arms and
artillery are perfectly kept, whatever the weather may be.

Some commanders of infantry Divisions, during the present war, have
neglected to take as good care of their artillery as of their infantry.
This is a mistake to be avoided. There are no more infantry Divisions.
Our Divisions are composed of all arms, each having a special utility,
and all must, without any discrimination, receive the care and
supervision of their Chief.

THE STAFFS. The unit commanders need the assistance of officers
thoroughly imbued with their thoughts, able to express and transmit
them faithfully.

_Chief of Staff._ In every unit we have a general or superior officer,
called “Chief of Staff.” In a Division taken as a unit, this officer
is entrusted with the direction of all the divisional services and the
services at headquarters. He is responsible to his commander for the
perfect working of all these services, and also for the wording and
prompt transmission of all orders.

While the task of inspecting the troops (especially the fighting
troops) rests with the General, the Chief of Staff should more
particularly inspect the non-combatant services and personnel, namely,
the Health, Supply, Treasury, and Post Office Departments.

_Staff-Officers._ It would be a great mistake to divide the
staff-officers otherwise than into two very distinct classes:

1st. Staff-Officers proper, who are the direct assistants of the Chief;

2d. Office Staff, entrusted with all the clerical work, except that
concerning the preparation and conduct of the operations, and the
report thereon.

The latter need not possess military science. They can efficiently
fulfil their duties if, as civilians, they have been trained to prepare
written reports, and they need not possess the physical endurance
necessary to the staff-officers proper.

To be efficient, a staff-officer needs to possess military science,
judgment, tact, physical strength, great activity, bravery, and
self-abnegation.

By adhering to the above classification, the American Army will have
no trouble in forming excellent staffs. In fact, it will not have
to triumph over a routine that three years of war has not entirely
eliminated from our old European armies. Too often we injudiciously
employ for tasks unfamiliar or unsuited to them officers capable of
rendering much greater services elsewhere.

The staff-officer will be efficient if he performs the following
briefly stated duties:

The staff-officer must complete by a minute reconnoitring the
inspections previously made by the General himself. He should never
hesitate to go to the very first lines, and it will be often necessary
for him to go under the protection of patrols of infantry, and
ascertain in person to what extent the first lines of the enemy have
been destroyed, how much damage has been done to the wire entanglements
and defences, etc.

The staff-officer must be a perfectly trained aërial observer. He
should also be competent to detect on the different photographs
furnished by the aviators the least damage done to the enemy’s works by
the successive projectiles. This task, which must be accomplished most
conscientiously, requires excellent eyesight.

We do not hesitate to say that, in the present war, it would be
criminal insanity to deliver an attack without being sure that the
enemy’s wire defences have been sufficiently damaged; at least to
such an extent as will allow the infantry to pass through them.
A staff-officer should not at this most important juncture trust
implicitly to the information furnished him in reports from the first
lines or found in the photographs taken by the aviation, but he ought
to go and see for himself and report minutely to his Chief.

These are dangerous missions: hence the need of having staff-officers
in reserve. It has been repeatedly proved that officers who have
not been trained at the Ecole d’Etat Major (staff school), but are
experienced and efficient men, quickly become excellent substitute
staff-officers.

Their principal duties may be summed up as follows:

Keep their Chief informed before, during, and after an operation.

Their office work ought to be limited to the writing of orders and
reports concerning the operations. This is easy of accomplishment when
the commander has a comprehensive grasp of the situation, and gives his
staff clear and concise orders, which they have only to put into effect
in due form.

The staff-officer must also act as an intelligence officer. As close to
the General’s headquarters as possible, a staff-officer must establish
a centre of information, where he will keep a force of men and all
the equipment that will enable him to keep in constant communication
with his General, with the infantry, the artillery, the captive
balloons, all the services of the aviation, etc. When a reconnoitring
aviator returns with some important information, unless he has been
able to communicate it by wireless, he lands as near as possible to
the intelligence bureau, gives to the staff-officer in charge an
account of what he has seen, and flies off. The staff-officer transmits
immediately to the proper quarter the information he has just received,
and it is his duty in all important cases to make sure that his message
has reached its proper destination. If telephonic communication has
been interrupted by any accident of battle, he must despatch some of
the estafettes, dispatch-runners, or carrier-pigeons at his disposal.

AVIATION

  1. Its military beginnings. Its increasing importance.

  2. Its use and scope.

  3. Different kinds of aircraft. Battle-planes. Bombing-planes.
       Observation--or scout-planes. Employment of scout-planes
       for the direction of artillery-fire and the movements of
       infantry. Aviation during a battle.

  4. Hydroplanes.

  5. Balloons, Zeppelins.


=1. Its military beginnings, its increasing importance.= At the
beginning of the war, Germany alone possessed a military flying corps.
She was the only nation who desired war. She was the only one prepared,
in this as in other respects. Her foresight was duly rewarded.

Though still few, her aviators found themselves the masters of the air.
They made themselves very useful to the German Command by observations
that enabled them to locate the principal French forces. They rendered
also great services to their artillery during the actual fighting. A
German machine, while clumsily flying some 3000 feet above the French
batteries, would send up a rocket, and a few minutes afterwards 150 mm.
shells would begin to fall on the spot thus indicated.

If, at the time, the Germans had been as expert as they are now in
pointing their guns, these air-directed bombardments would have had
more efficacious results, but even as it was, they invariably produced
a deplorable impression on the morale of the troops who felt themselves
at the mercy of a shell-fire which the French artillery could not
return for want of howitzers.

Aviation had developed itself mostly among the civilians in France.
Overnight, as it were, our civilians became military aviators. They
showed great bravery and a few at once proved themselves remarkable.
Their machines, though speedy, as speed was reckoned in those days,
were in many ways inadequate for the purposes of war, but they were
none the less extremely effective.

Since 1914, all the belligerents have, with more or less success,
considerably developed the scope of their aviation.

In France there was too much indecision as to what types should be
adopted.

The production of standardized machines encountered serious
difficulties. Construction was slow. Factories either lacked machinery
entirely or were insufficiently supplied with it.

Till the autumn of 1915, Germany retained the supremacy in the air.
From that time on the situation gradually altered in favor of France,
and since the arrival of a large contingent of British machines, the
Allies have maintained a marked superiority on the Western Front. When
the American air-corps has added its strength to the French the end of
the German aviation will be close at hand.

It is well nevertheless to note that the Germans, fearing the advent
of the American airmen, are now making a powerful effort to double the
number of their planes; and, aided by a careful study of the Allies’
machines which have fallen in their lines, are busy constructing more
and more formidable examples. The Allies, in the meantime, are daily
improving their own, and the Americans have lately had the occasion to
see that Italy, one of the most recent aviation recruits, has nearly
reached perfection in aircraft construction.

In order to render promptly the anticipated aid, the United States
should, at the beginning at least, adopt thoroughly tested types of
aircraft, of easy control in the air; and should construct several
standardized motors.

After trial _on the French front_ some types may have to be modified,
but only after the American aviation corps has made sure that, in any
event, it will have a sufficient number of aircraft in France while
awaiting the arrival of the new models.

Airplane construction has been hitherto, and will continue to be,
constantly progressive. An improvement much needed is a device for the
protection of the gasoline tank, which on most of the existing types is
too vulnerable and too frequently set on fire. Very often the Germans
aim at the tanks rather than at the pilot, as the former are easier to
hit and the result is the same.


=2. Use and scope of aviation.= Our opinion is that during the present
war no real success can be obtained without the help of numerous
and daring aviators. During the days preceding an attack (in the
trench war) or in order to hide the movements of the troops (in the
open field) it is of the utmost necessity to maintain the supremacy
in the air. The enemy’s aviation must be entirely blinded. Not one
enemy machine must pass over the lines. The captive balloons must be
destroyed. In brief, the aviation must be powerful enough to prevent
the enemy from having any knowledge of our preparations, and above
all from ascertaining the exact point whence the main attack will be
launched.

Besides the work it will have to do on the front (with which we will
deal hereafter) the aviation of bombardment will, during the period
of preparation, have to make numerous raids on the enemy’s rear, hurl
destruction upon the aerodromes, and into the camps of the staff and
reserves, blow up the important ammunition and food stores, attack the
trains, destroy the railway lines, especially at the junctions, set the
stations on fire, and attack all detachments and convoys on the roads.

Briefly, the aviation should, during the preparation for an attack
supplement at the rear the disorder created at the front by a prolonged
bombardment. If these desiderata are complied with by sufficiently
numerous and powerful aircraft, the enemy will find themselves in
evident inferiority at the moment of attack.


=3. Different kinds of aircraft.= There are several kinds of airplanes:

BATTLE-PLANES. The importance of the fighting aviation far exceeds that
of the other kinds, owing to the fact that whatever their mission, the
latter cannot keep the air either on the front or during the raids back
of the enemy lines unless they are protected against the attacks of the
opponent’s aircraft by a sufficient number of lighter, swifter, and
more easily manœuvred battle-planes. The organization of the fighting
aviation ought, therefore, to claim the principal and most careful
consideration of the commanding officer in charge of all the different
services of the flying corps.

Fighting machines must be very numerous, and piloted by cool, competent
aviators, masters of their machines and possessing what, in France, our
soldiers call “Cran”; _i. e._, Pluck.

At the present moment there is an obvious tendency to abandon
monoplanes in favour of small, very handy biplanes flying 220
kilometres an hour. Our renowned “aces,” such as the late Captain
Guynemer and so many others, have, until now, fought single-handed,
piloting and shooting at the same time. We are returning to the idea
of placing two men on these fighting machines.

Some of these are already fitted with two very light and extremely
accurate machine-guns, the front one being fixed so as to shoot through
the screw. This result has been obtained by the use of a device so
marvellously accurate that the ball at its exit from the barrel of
the gun never hits the blades of the screw speeding at more than one
thousand five hundred revolutions a minute.

For a long time, our French aviators operated separately, but the
Germans having taken the habit of flying in groups, our aviators, in
most cases, fly now in squadrillas so as to be able to help one another.

The battle-plane aviators fly at great heights, hiding themselves
behind the clouds, and, when they see an enemy machine below them, they
drop on it with all speed and attempt, while keeping above it, to shoot
it down.

When they are attacked, they try to rise and gain the advantage of
position. Their tactics, in brief, consist in getting as much as
possible out of an enemy’s range, and in attaining such a position as
will enable them to reach him.

Some of these fights last ten, some fifteen minutes.

When the weather allows flights, there ought always to be several
battle-planes in the air to protect the other kinds of airplanes.

One must lay down as a rule, and we here repeat the opinion expressed
by famous aviators, that every attack, whether by a single machine or
by a squadrilla, must always be carried out with the utmost vigour. The
Germans seem, indeed, to have received orders to fly away whenever they
feel themselves inferior.

An important function of the battle-planes is to escort and protect the
scouting or raiding squadrons during their operations, so as to allow
the latter to fulfil their mission without having to guard against any
possible attack of the enemy.

During these expeditions the battle-plane is to the other airplanes
what the destroyers are to the ships they convoy. In order that they
may afford efficient protection to the ships, the destroyers must
be very fast and manageable; likewise the chasing airplanes must of
necessity be more rapid and manageable than those they are sent to
protect.

BOMBING-PLANES. The number of machines composing a squadrilla of
bombardment varies. Several squadrillas often start together to
accomplish a mission, forming an aërial army. The machines thus
detailed must be able to carry a heavy load of ammunition, also a
provision of gasoline sufficient to allow them to remain a long time in
the air.

To realize the progress made in the construction of such machines one
has but to remember that, on the 15th of last October, an Italian
airplane carrying a great weight in addition to its supply of gasoline,
covered the distance from Turin to the English coast in ten hours.

The Italians have now at Washington a machine carrying twelve
persons. All the Powers are building large airplanes intended to make
bombardments more and more deadly.

At first, ordinary bombs were dropped from airplanes, but they are now
supplied with special bombs filled with the most powerful explosives
known (winged torpedoes), and also incendiary and asphyxiating
projectiles. Special devices have been constructed which increase the
accuracy of the aim, when dropping bombs.

These bombing-planes are armed with quick-firing guns, but are less
handy and manageable than the battle-plane, whose protection,
therefore, they require.

We are confident that our American friends will develop to the extreme
limit their aviation of bombardment, and will train a great number of
their aviators for long-distance flights by night or day. Very many
of the most important military establishments in western Germany are
within reach of our blows. Up to now the insufficiency of our material
has been the sole reason of the failure of our aviation to attempt
the destruction of her plants at Essen, Cologne, Manheim, Metz, etc.
Certain expeditions have proved that all these places are within the
reach of fairly good machines piloted by well-trained aviators.

What would become of the Essen works the day that 1200 or 1500
airplanes attacked them in groups of 30 or 40, following each other
at ten-minute intervals; some bombarding the works with high-power
torpedoes, others with incendiary bombs, others with suffocating
projectiles, utterly demoralizing the workmen and spreading terror in
their midst?

Certainly there would be losses, for the Germans have surrounded their
works with numerous anti-aircraft guns, but would the more or less
complete destruction of the Essen works be too dearly bought by the
loss of a number of machines? Moreover we do not believe that a raid on
their big plants, if well prepared and well carried out, would be very
costly.

The use of aviation to destroy the enemy’s munition plants will, in our
opinion, greatly hasten the end of the war, and spare a large number of
lives.

If the war lasts, the long-distance aviation will have to be employed
very extensively during the summer to set fire indiscriminately to
the harvest in the enemy’s country, and even in the territory which
they occupy as invaders, since there is no reason to spare the invaded
sections as long as the natives are not allowed to have their share of
the crops. Furthermore, devices will have to be invented to facilitate
this work of destruction.

It is materially impossible to give the bombing-machines a speed equal
to that of the battle-planes. Great importance however must be attached
to the choice of motors and to obtaining the greatest speed possible.

All these machines have two propellers and some are provided with three
motors.

The first bombing expeditions were undertaken during the first months
of the war. From the very beginning, the Germans realized that
airplanes could go far and strike dangerous blows. Paris was bombarded
as early as September, 1914. In time, and as the machines were
improved, the bombardments became more disastrous. In the course of the
first half of 1915, British aviators dropped bombs on Friedrichshaven,
the Zeppelin station on the Lake of Constance; French aviators attacked
Stuttgart and Carlsruhe; and since the beginning of 1917, the Germans
have multiplied their raids on London and the coasts of England.

We believe that bombing aviation, for purely military purposes, will
assume an ever-increasing importance in the war.

OBSERVATION OR SCOUT-PLANES. On the French Front the old types of
reconnoitring machines are being replaced as quickly as possible. They
were too slow and not easy to control in case of an attack.

The services rendered by the reconnoitring airplanes are of the
greatest importance. Their observations supply the Command with
accurate information concerning everything that is taking place within
the enemy’s lines; the condition of his front; the movements of troops
in his rear; thus enabling the Chief to foresee his intentions and foil
his plans.

In addition to reports of what they observe during their flights, the
pilots obtain aërial photographs. This very important adjunct of our
modern armies has been considerably improved.

Photos taken at an altitude of 2500 and 3000 metres (8000 to 10,000
feet) reproduce so accurately the configuration of the land with every
object on it, that trained officers are able to observe in them the
smallest changes that have been made. With this object in view they
compare together several photos of the same place taken at different
dates.

We include in our volume some aërial photographs of the German lines in
the Aisne sector taken at the end of December, 1916, in January, 1917,
and in April and May, 1917. The first show merely the enemy’s works
before the French bombardment. The pictures taken in April of the same
ground give an excellent idea of the progressive effect of the French
artillery, and the last photographs, taken during the attacks of the
5th and 6th of May, show the final result of the tremendous shell-fire.
In order to compare the changes effected from time to time, it is
necessary to use a magnifying-glass, and to note successively each
observation on a large-scale map called a “directing map.” This minute,
painstaking method alone will enable the Staff to form an idea of the
effect of the artillery, and the progressive demolition of the works
and trenches of the enemy. Later on we will see that the observations
reported by the reconnoitring aviation influence in a great measure the
dispositions taken for attack.

The British attach, and rightly so, such importance to a strictly
accurate record of the effects of their fire, that they are not
satisfied with the usual charts, but construct for their principal
staffs large-scale relief-maps including both their own and the German
lines, works, and batteries, as revealed to them by photographs taken
from airplanes and captive balloons. Officers of the General Staff are
specially entrusted with the duty of recording on this relief-map all
damage and destruction as fast as it is reported. When the order of
attack is given, the British chiefs, knowing as far as it is possible
what works they will find destroyed, and what points will offer a more
or less stubborn resistance, make their dispositions accordingly.

No attack is possible if the Command is not daily informed by the
photographic section. Even after a continuous bombardment it is more
prudent to defer an attack if during the preceding days the weather has
been so bad as to prevent the use of the aërial cameras.

USE OF SCOUT-PLANES TO DIRECT ARTILLERY FIRE. Special and sufficiently
numerous squadrillas must be reserved for the exclusive use of the
artillery, and more particularly for that of the heavy artillery in
order to supply them with the proper range.

At times, captive balloons can help the heavy artillery in this
respect, the gunners preferring them to airplanes; but these balloons
are not always sufficiently numerous and cannot always see far enough.

The guiding airplane informs the batteries to which it is assigned of
the effect of their shell-fire by means of wireless telegraphy, which
has the advantage of not being interrupted by the terrific noise of the
bombardment, whereas telephonic communication with a captive balloon is
impossible without the use of special “hearing masks.”

Different kinds of rockets can also be employed for indicating the
range under certain circumstances.

USE OF SCOUT-PLANES TO DIRECT THE MOVEMENTS OF INFANTRY. The
squadrillas of a Division are provided with devices for guiding the
movements of infantry.

Their duties are manifold. At all times they are kept hovering over the
first lines to watch the enemy and give warning of all unusual moves.

During an assault their principal duty is to secure the indispensable
unity of action between the infantry and the field artillery. As we
will explain further on, every attack made by the infantry is screened
by a terrific barrage fire that advances about one hundred yards ahead
of the first wave. In order that such a barrage may continue to be
properly effective it must progress at the same speed as the infantry.

For this purpose scout-planes are equipped with a special rocket, that
signals, “Increase the range.” Each rocket sent calls for an increase
of one hundred metres in the range.

During the fight the duties of the aviator as watchdog of the infantry
do not cease. He has to observe the slightest moves of the enemy,
and he is usually able to warn his commanders of the preparation of
counter-attacks, of their direction, and of their strength.

The services rendered by the guiding aviation to the artillery and
infantry are obviously of capital importance. Its mission, if properly
executed, is extremely hard and laborious, hence the necessity, in the
future, of increasing the number and efficiency of these squadrillas as
much as possible. In order that they may operate successfully they must
be closely protected by powerful battle-planes, unless the latter have
already cleared the region of enemy machines and left them the mastery
of the air.

AVIATION DURING BATTLES. Since the battle of the Somme, the British
and French aviation has taken, day by day, a more and more direct part
in the actual fighting. The Germans, whose aircraft were originally
employed only for scouting purposes, were not slow in imitating them.

During all the recent Franco-British offensives, machines of all types
were seen flying down as low as one hundred and even fifty yards
above the enemy’s terrain, raking the reserve lines with machine-gun
fire, shooting down the gunners of exposed batteries, surprising
reinforcements on the march or coming up in troop trains, and
spreading disorder everywhere.

In Artois, a moving train attacked by three British machines was
wrecked with great loss to its crowded freight of infantry.

It is a pleasure for a Frenchman to pay to the British aviators the
tribute well earned by their valour and enterprise. Sportsmen that
they are, the English from the very first have taken to aviation as
a sport, and have given themselves to it heart and soul. The results
they have achieved are wonderful. They might perhaps have accomplished
feats equally brilliant with smaller losses; nevertheless we cannot but
admire the high courage of their young men, who, scorning death, have
bent all their energies to achieve success.

The preceding brief summary of the uses of aviation in the present war
justifies what we wrote at the beginning, viz., the side that has the
uncontested supremacy in the air, the side that has done away with the
adversary’s aviation, will be very near the final victory.

But in order to safely and rapidly reach this result, the Americans
should, in the organization of their flying corps, consent, at least in
the beginning, to make a sacrifice of their pride as inventors.

It will be absolutely necessary for them to commence the fight in the
air with none but planes already successfully tested at the front
in the various branches of the aërial service. It matters little
what types they select from among the best now in use by the French,
British, Italians, and even by the Germans; the important point is the
achievement of swift and sure results, and these can be obtained only
with such aircraft as have proved their worth in actual warfare.

Otherwise, the Americans would expose themselves, at the start, to the
useless loss of numerous planes, and the sacrifice of many precious
lives. They would delay for several months the perfection of an arm
which is expected to give prompt and decisive results on the Western
Front, and thus cause as great a disappointment to the American as to
the Allied Armies.

The adoption of such a policy would not, however, prevent the American
engineers from improving progressively upon their original aircraft.
During the last three years airplanes have been continually modified
and improved. Still greater improvements may be expected in the
future, and in this line a vast field remains open to the American
genius.


=4. Hydroplanes.= A brief mention should be made of hydroplanes, or
sea-planes, which, although usually equipped only with the pontoons
that enable them to alight upon the water, are equally fitted for a
landing on terra firma by the super-addition of wheels. Most of the
British attacks upon the German airdromes, encampments, and fortified
lines on or near the Belgian coast have been made from hydroplanes.
These machines have proved of great value for patrolling the coast
against submarines. The aviators can see the submarines at a certain
depth under water, and following in pursuit, they attack them by
dropping special bombs, which, like those used by destroyers when
passing over a submarine, are so constructed as to explode at a certain
depth by water pressure even if they do not strike their target. The
force of the explosion is sufficient within a radius of many metres to
disjoint the plates of the submarine.


=5. Balloons--Zeppelins.= At the outset of the war the Germans had
a marked superiority in dirigible balloons. They had then already
completed their particular type of rigid dirigible balloon, the
Zeppelin, which they have since improved and multiplied to the full
extent of their ability. Only at sea have they used them for strictly
military purposes, observing very advantageously by their means the
British fleet and flotillas. In the fighting on the Western Front they
have used their Zeppelins but once, in the course of their attempt upon
Verdun, when an effort was made to destroy the Paris-Verdun railroad
track. Two days before the attack they dispatched a couple of the great
airships on this errand, but one was brought down and the other was
driven away before they could accomplish their mission.

All the other Zeppelin expeditions on the Western Front have been
made not against combatants but against towns. While they have caused
a great many casualties among the civilian population in the Allied
countries, a large number of them have been shot down.

France has used for distant expeditions a few non-rigid dirigibles and
has lost several of them.

England, for the protection of the Irish sea and the Channel, uses some
very swift little dirigibles which are very easily handled and form an
excellent submarine patrol, but as fighting units they are worthless
and are obliged to flee from hostile airplanes.

=1. General Remarks.= When her dream of a short war which was to
realize all her aims of conquest was dissipated, Germany resorted to a
policy of occupation in the hope of either maintaining her hold upon
the territory she had seized, or else of eventually using it as an
asset in negotiations for peace. At the end of 1914 she occupied nearly
the whole area of seven French Departments, three or four of which are
among the richest agricultural and industrial districts of France.

To attain her ends, Germany intrenched her armies on the nearest front
that she had time to occupy, one of several defensive lines which she
had selected long before. Her spies, in time of peace, had furnished
her with accurate knowledge of all the important positions.

Thus, when the German armies of the first line were beaten on the
Marne, and fell back in disorder, they found, at a distance of three
or four days’ march, beyond Soissons, on the frontier of Lorraine, an
unbroken line of intrenchments already organized by the second-line
troops while they were operating their enforced retreat.

The French pursuing armies had not, in September, 1914, the material
means of assaulting the enemy’s intrenchments. They had just fought
a series of battles which had considerably lessened their effective
forces. Their regiments had to be officered anew. They had no
alternative but to intrench themselves, on positions as little
disadvantageous as possible, in front of the enemy. Thus all along a
line extending from the North Sea, at Nieuport, to the frontier of
Switzerland, began the formidable conflict which is still raging.

The distance between the two hostile fronts varies from 30 or 40 metres
to 1200 or 1500 metres at most.

After big attacks, prepared by long bombardments, the first lines cease
to exist, and very often both of the hostile fronts are merged into one
another. The most advanced small outposts have no other shelter than
that of shell-craters, and it is by means of grenades thrown from one
crater to another, and with whatever earthworks can be improvised with
the tools on hand, that attempts to rectify the fronts are made.

Both parties, most of the time, have three successive lines of
organized defence, and sometimes more.

It is to be noted, however, that while the Germans have adhered to
the three-line principle in the sectors where they believe themselves
but slightly threatened, on the fronts where they are heavily pressed
by the Allied Armies, they have organized, as their advanced lines
weakened or were forced, a series of very strong positions, one behind
the other. It is impossible to be precise as to the number of these
lines. According to the reports of the aviators, several complete
systems of defences exist between the positions they are now defending
and the Meuse.

It is interesting to remark that the multiplication of large-calibre
artillery has caused changes to be made by both belligerents in the
construction of shelters and intrenchments.

During the winter of 1914–1915, no serious bombardments took place
before April. Both sides organized themselves on their positions,
excavating shallow shelters which were braced with wooden beams and
roofed with two or three layers of logs, over which earth was more or
less thickly packed. Such shelters resisted well enough 150 mm. shells.

But, in 1917, during the operations in Artois and Champagne, the
adoption of larger calibres, and the use of torpedoes fired by trench
machines, compelled the belligerents to bury themselves more deeply
in the ground, wherever the soil permitted, and to build more solid
shelters. When water interfered with deep excavations, the shelters
were covered in with very strong T-shaped iron railway ties, or with
several layers of steel rails; but these proved insufficient, and the
Germans were the first to construct those bombproofs of reinforced
concrete which the British for the first time encountered on the Somme.
The concrete blocks are very large and the steel reinforcing bars
extremely strong. Such works certainly impede and delay the operations
of the enemy, especially when they are extensively employed, but
events have proved that, given time, they can always be destroyed by
gun-fire. The French have constructed similar works only at points
of capital importance. They prefer the old wooden shelters, well
reinforced with earth.

[Illustration: Ailles and its western approach

February 10, 1917--2.30 P.M.]

At all the inhabited places in their lines, and at points of natural
strength, the Germans have organized independent centres of resistance.
They have transformed whole villages into fortresses. Mention need
only be made of the labyrinth of Carency-Thiepval, Beaumont-Hamel, the
tunnels of Cornillet, of Hill 304, of Mort-Homme, etc.

In every one of those places a surprising number of concrete
constructions and superimposed subterranean galleries were discovered.
In them the enemy had collected reserve troops, food, and munitions.
Such shelters, no doubt, afforded the Germans great protection, and in
order to destroy them, it was necessary to have recourse to more and
more powerful methods.

An officer of the 81st Regiment of Infantry which captured Mort-Homme
writes as follows: “ ... and on the hill where the 81st Regiment is
encamped, what an accumulation of defensive agencies! Wire, tunnels,
trenches, observatories, shelters of every description, machine-gun
posts, light cannon, nothing is lacking. To these ordinary means of
defence, other extraordinary ones had been added, consisting of three
immense and very deep subterranean systems (82 steps led down to
one and the length of another exceeded one kilometre) provided with
ventilators, Decauville narrow-gauge railways, electricity, posts of
command and relief, rooms for the men, and stores for food, arms,
munitions, and material. All these extraordinary fortifications could
not resist the impetuous assault of our troops, which had been preceded
by a six-day bombardment so intense that the entire first line was
enveloped in a thick cloud of smoke about two hundred metres high, and
the ground shook all the time.”

In fact, no absolutely impregnable shelter has yet been devised,
and the story of fortification is but a repetition of the story of
defensive naval armament. The thicker the plates of the dreadnoughts,
the more powerful the guns are made, and the guns have the last word.

Moreover, it has been by no means demonstrated that the German
intrenchments, which have cost enormous sums, and an amount of human
labour that the Allies would have been unable to furnish, have to any
extent reduced the enemy’s losses. On the contrary, it appears that the
temporary protection afforded by such works is more than offset by the
great losses in men and material which is the result of their final
destruction.

The official reports which reach us, just before going to press, of
the French victory of the 23d-25th of October, 1917, on the Aisne,
prove that, in the captured salient (which the Germans had considered
of capital importance), they had accumulated means of defence more
considerable and powerful than at any point hitherto conquered.

At the inhabited points, they had converted all the cellars of the
houses into bombproofs. They had bored tunnels of communication,
some of which were a mile long. Everywhere they had built formidable
concrete dugouts connected by covered passages loopholed for
machine-guns, and had even mounted heavy pieces of artillery in their
first lines. The whole position was considered so impregnable that they
had stored in its subterranean spaces a very large quantity of winter
supplies. The topography of the region was unusually favourable to the
construction of defensive works, and a number of natural grottoes had
been turned to good account.

In a few days a powerful artillery had enabled a heroic infantry
(fighting under the eye of the American General Pershing) to overcome
the resistance of an enemy defending his ground with a force of about
nine divisions. This operation justifies once more our assertion that
it is impossible to construct works that are absolutely impregnable to
gun-fire.

To give an idea of the morale of the French, we can do no better than
to cite a passage from a letter, written at the Front on October 6th,
which we have just received from a young artillery officer. “Watch the
communiqués that will be issued on or about the 20th day of October.
We are preparing for the Boches a song and dance that they will not
forget.”


=2. General plan of an intrenchment system.= The description we give
hereafter of the organization of the lines is, of course, like the
following diagram, purely explanatory and illustrative.

[Illustration: South-east of Ailles

February 10, 1917--2.30 P.M.]

It is intended to set forth the principles governing
trench-construction and to give a general idea of a system of field
fortifications. Such a system is subject to the exigencies of local
topography, and it is therefore impossible to state exact measurements
and distances for the broad outlines of the plan.

Thus one could formulate no law to fix the distance which should
separate the different lines of an intrenched position; and even with
regard to the breadth of the interval between two trenches of the same
line, one can scarcely be more precise; since, however essential it may
be in theory to make it broad enough to prevent a single shell from
doing damage to both trenches, in practice the configuration of the
ground does not always permit of such a precaution.

The plotting-out of the trenches is of very great importance. They must
be made in such a manner that they will not be exposed to an enfilading
fire of the enemy’s guns, and will be strong enough to oppose the
greatest resistance to attack.

Too long and too straight lines are generally avoided. The usual custom
is to reproduce the ground plan of a bastion, with alternating salients
and re-entrants, a disposition which permits flank firing across the
front of the trench (Fig. 1).

The re-entrants are frequently additionally fortified so as to render
them insurmountable to assault, so that the defenders need occupy the
salients only. Advanced trenches exposed to intense bombardment can
thus be defended with a smaller number of men.

[Illustration: _FIG. 1_]

The inside of the trenches is provided at short intervals with
_pare-éclats_, or shell-screens, consisting of buttresses of earth
supported by _clayonnages_, or wattle-work, which are intended to limit
as much as possible the radius of action of a bursting shell to a
single section of trench (Fig. 2).

The trenches are of different dimensions; nevertheless, when time
is not limited for their construction, Fig. 3 can be considered as
representing the most generally adopted type. The earth thrown up in
front, either loose or filled into sandbags, forms the parapet.

As the action of the weather, especially rain, tends to cave in the
sides of the trenches, they have to be upheld with wooden props, or
with wire nets, supported at three or four metre intervals by wooden
or iron posts.

[Illustration: _FIG. 2_]

[Illustration: _FIG. 3_]

In the very damp regions small drains (_rigoles_) and cesspools have
to be dug to carry off the water, and the trenches themselves must be
provided with open “boardwalk” flooring. When not pressed by time
and scarcity of material, especially in winter, all possible means
should be adopted to prevent the men from standing too long in water.
Dampness, more than cold, is responsible for frostbitten limbs.

[Illustration: _FIG. 4_]

In the parapets of trenches that are expected to last some time,
loopholes are made by inserting pieces of sheet-steel with openings to
allow the passage of a gun barrel. Each opening closes with a small
door which remains shut except when the loophole is in use (Fig. 4).

[Illustration: South-east of La Bovelle Farm

February 10, 1917--2.30 P.M.]

When neither time nor material is lacking, the machine-gun shelters
(Fig. 5) in the trenches are installed within steel cupolas, which are
either stationary or revolving. The mechanism of the latter is,
however, complicated, and too delicate for use in the first lines.
These cupolas are also much used for observation posts, and, as we
shall see later, they are kept as much as possible concealed from the
sight of the enemy by camouflage.

[Illustration: _FIG. 5_]

The first line comprises three positions or trenches. That nearest to
the enemy is the advanced trench, and at a short distance behind it are
the support trenches. Only a few men are now posted as sentries in the
advanced trenches. In front of these trenches, “listening” or “watch”
posts are hidden in the ground. Between these posts and the advanced
trenches barbed wire entanglements are stretched, in number and width
proportionate to the dangers threatening the position.

In the support trenches are the dugouts sheltering the men against the
fire of the artillery. Many communication trenches or _boyaux_ connect
them with the advanced trenches, facilitating the rapid occupation
of the latter in case of need. In the advanced trenches are built
shelters for the machine-guns. Rifle-fire is directed through loopholes
protected by the steel plates above mentioned (Fig. 4) which are
bullet-proof at fifty yards.

At some distance to the rear of the support trenches and overlooking
them, the first-line system is reinforced by a line of “centres of
resistance,” which is punctuated with blockhouses protected by thick
wire entanglements. Well sheltered machine-guns, a certain number
of which sweep the communication-ways leading to the front, compose
their main armament. This blockhouse line is connected by many
communication-ways with the trenches in front of it.

These centres of resistance are intended to check the advance of the
enemy, when they succeed in breaking into the three anterior lines, and
to give the reserves time for counter-attacking.

Between the blockhouses and the second-line system a fortified line
is frequently organized which is called the “protecting line of
the artillery.” This is intended to repel the advance of the enemy
infantry, if they gain possession of the first-line system, before they
reach the field batteries, or to retard it long enough to allow the
batteries to fall back. This line is held by the troops of the sector
which do not belong to the fighting contingent.

The distance from the first-line system of trenches to the second-line
system varies according to the configuration of the ground. These
second lines should, when possible, overlook the first lines, so as to
hold them under their fire. The same rules prevail in the location of
the third lines. In the sectors which seem to particularly interest the
enemy, very strong “check positions” are prepared in the rear.

The troops occupying the second and third lines should be protected
against bombardment as much as possible. It is therefore in these
trenches or very near them that shelters capable of withstanding heavy
gun-fire should be constructed.

We say “in or near” advisedly, for it is important to hide the shelters
as much as possible from the enemy, and, to effect this, it is no
inconvenience to build them a little in the rear of the trench-lines,
if the desired result can thus be obtained. Often it will be necessary
to do this merely for the purpose of getting more favourable ground on
which to erect the shelter.

The main point to emphasize is that these shelters should be connected
by means of communication-ways permitting quick passage from the
shelters to the trench-lines.

In all three lines, when the ground is suitable, observation posts are
located, but however well they may be concealed, the enemy is not long
in discovering them, and in the first line it is generally with the aid
of different kinds of periscopes that the observations are made.

COMMUNICATION LINES. All the trenches are connected by communication
trenches or _boyaux_, which conceal from the enemy the movements
of troops. These are mere ditches about two yards deep, the earth
from which is thrown out to the left and right, or on one side only.
They follow a zigzag line so as not to be exposed to enfilading
fire, or, when straight, are protected at intervals by earth screens
(_pare-éclats_).

[Illustration: Diagram of Campaign Intrenchments.]

The depth or breadth of these “ditches” depends on the use to be made
of them. For instance, those intended for carrying out the wounded
must be deep and wide.

To preclude obstruction during attack, and to provide free and quick
passage for reserves rushing up from the rear, communication trenches
should be very numerous. Some should be designated for forward and
some for rearward movement. Each one should bear a name or a number
and at its extremities arrows should indicate the direction of the
circulation. Thus confusion will be avoided.

TRENCHES OF ATTACK. When the opposing lines are sufficiently far from
one another, it is impossible to launch an attack without having
brought the infantry within striking distance.

For this purpose a sufficient number of _boyaux_ are dug in the
direction of the enemy, starting from the advanced trenches, passing
under the wire entanglements, and connecting together with a
cross-trench when at the required distance. This is the “trench of
attack” and at the proper time, steps are made in it to facilitate the
egress of the troops at the moment of assault.

This work is done at night, and preferably, when possible, by troops
which are not to take part in the attack. The men proceed to this work
under cover and patrol guard.

ARTILLERY. The artillery, according to its size, is placed between the
lines or behind them. Field batteries are pushed forward up to the
“artillery protecting line” and placed in position to shell, at any
time, certain designated portions of the enemy’s front. They are either
buried in the ground or sheltered under casemates, when the latter can
be concealed from the enemy.

The trench-guns are, generally, on account of their small range, placed
in the first-line support trenches.

The heavy artillery, farthest back of all, is drawn up in echelons
according to its size and the part assigned to each part of it.

WIRE ENTANGLEMENTS. The width of the wire entanglements varies
considerably. Well-strung wire prevents any attack, and none can be
attempted until the entanglements are destroyed. In front of their new
lines on the Aisne, where the Germans are simply holding the ground,
and have given up all notion of advance, they have stretched eight or
nine successive rows of wire, each row being fifty metres wide.

Wherever defence only is contemplated, the protection of wire
is essential, but it will be well to bear in mind that too many
entanglements may prove inconvenient at the time of an attack. We
have seen that in such cases, the difficulty is solved by digging
communication trenches under the wires.


=3. Mines and counter-mines.= Since both parties dug themselves in,
much use has been made of mines and counter-mines, especially in 1915
and a part of 1916.

The aim of the mine is to throw the enemy into sudden consternation
and disorder, while destroying an advanced trench, or work. The French
considered the mine as a weapon with which it would be possible to
remedy at certain points the defects of their line.

They caused heavy losses to both parties, but are not so much used
now for the very good reason that, where the fronts have undergone
no change since 1914, the soil has been so greatly disturbed that it
would be absolutely impossible to make the necessary excavations. We
shall simply recall that in June, 1917, the British, prior to their
attack on Messines, set off twenty mines, each containing twenty-three
thousand kilograms of explosive, and as the Germans were not aware
of their construction, the effect of the explosions was terrible,
producing huge craters, seventy metres deep and several hundred metres
in circumference.

Mines are dug by hand or electric drills. The latter have the
disadvantage of making too much noise. Greatly improved systems
of “listening posts” permit the enemy’s operations to be detected
and opposed, and in all cases, excepting at Messines, where the
British bored their galleries at more than fifty metres underground,
mine-digging was carried on under great difficulties.

The best means to neutralize the danger of a mine whose construction
is discovered, is to reach it as quickly as possible by excavating a
“counter-mine,” and blow it up before the enemy has a chance to set
it off. The success of such a counter-mine is termed a _camouflet_
inflicted on the enemy.

In our opinion, mines and counter-mines will play a less and less
important part in the present war, but it will nevertheless be
necessary for our armies to be provided with the means of operating
them whenever the Command may deem them advisable.


=4. Special railway troops.--Transportation by roads.= Since the
beginning of the war, France has been lacking in special technical
corps, especially for the railways. Her ante-bellum system was
insufficient to cope with the rapid development of the military
operations, and the reorganization rendered necessary by trench warfare
along an extensive front.

A large proportion of the railroad employees was at first mobilized to
assist and reinforce the railway troops. Then, after a few months, a
large number of these men had to be sent back to their former civilian
duties, in order to assure the economical life of the country.

While the transport of troops alone requires a daily extension of our
road and railway systems, and constant attention to repair-work in
the fighting zones, the industrial efforts of the nation to equip and
arm the millions of combatants also necessitates an enormous railroad
activity. As the lack of workmen prevents locomotives and carriages
from being repaired, and the supply of rolling-stock shipped from
America is not sufficient, it is as much as the French can do to keep
their railroad tracks in good condition.

It should be noted that owing to the intense and forced use of her
interior lines to which we have already referred, the railways of
Germany are in still worse condition than those of France. For want of
oil and grease a large portion of their rolling-stock cannot be used.

To make up the deficiency in technical troops, France has had to have
recourse to her “territorial units,” composed of men unfit for the
Front and generally more than forty-five years old, who, exhausted by
three years of war, are unable to do much work.

This short résumé of the conditions prevailing on the rear of the
French Front will enable the Americans to comprehend the necessity for
organizing on a very extensive scale a special railroad transportation
corps. Without interfering with traffic on the principal roads
of the United States, it should be possible to create railway
regiments officered by civil engineers, with separate units for
track-construction, operation of trains, and repair of rolling-stock.

The engineer regiments should likewise be enabled to build rapidly
field-barracks of all kinds in the zones devastated and abandoned by
the Germans.

They should, moreover, be entrusted with the erection of hospital and
ambulance buildings, and their removal and reconstruction whenever new
ground is wrested from the enemy.

TRANSPORTATION BY ROAD. Except in the immediate vicinity of the lines,
where horses are still used by the regiments for transportation between
the camps and cantonments and the bases of supply, all the conveyance
of men and material, which is not made by rail, is done by motor-cars,
in daily increasing numbers.

Not only have the railways from the rear to the front been increased
in number, but also the communication lines running parallel with the
front. Their capacity, however, being inadequate for moving large units
quickly from one part of the Front to another, motor-cars should be on
hand in number sufficient for the rapid transportation of an entire
army corps.

There should be a permanent service of motor-cars between the front
lines and the rear, to assume the task of taking fresh troops to the
line and exhausted troops to the camping-grounds. They can be used
also, and with great efficiency, when circumstances at the Front
require the prompt advance of reserves from the various bases.

We shall see later how motor-cars are used for the supply of food or
ammunition. Many more cars are needed for the hospitals, ambulances,
and the carrying of the wounded.

The consumption of gasoline, notwithstanding the suppression of the
abuses which were for a long time prevalent on the Anglo-French Front,
remains considerable. France is supplied with it exclusively by the
United States and Mexico.


=5. General remarks on transportation.= The question of supplies of all
sorts will be one of the difficulties connected with the organization
of the American Armies on French soil. The United States will not
merely have to convey troops from one continent to the other, but also
to ship all that is necessary for the subsistence of her armies, their
upkeep, their armament, their artillery, etc., just as if they were
expected to land in a desert country where the barest necessaries of
life would be lacking.

The American Government and the General-in-Chief have from the start
been aware of the difficulties awaiting them, and, immediately after
the landing of the first troops, very important works were begun for
the improvement of the French ports of landing and for the duplication
of French railroads, wherever needed. This work is being actively
carried out under the direction of American engineers.


=6. Camouflage.= Everything pertaining to the equipment and employment
of troops must be hidden, so far as possible, from the sight of enemy
aviators, and the various devices resorted to for this purpose are
termed “Camouflage” (disguise).

Artillery, transportation parks, ammunition dumps, camps, roads of
communication, etc., are masked in many ways, on the general principle
of causing the object to be concealed to blend with the tint of the
soil or the foliage, or to melt into the landscape and avoid the eye.
Coverings of brushwood or straw represent the simpler, and framework
supporting artificial greenery or painted canvas, the more ambitious
forms of camouflage. Objects irregularly blotched with paint of
different colours are practically invisible at a certain distance--a
device borrowed from the “protective colouring” of the animal kingdom.

Batteries of dummy guns are often used in this, as in former wars, to
deceive the enemy.

It is highly important to have good points of observation within the
first lines, whence the enemy’s defences may be searched with powerful
field-glasses. To meet this need, artificial trees, rocks, etc., have
been provided when nature failed to supply them.

The camouflage of the French army has been entrusted to a special corps
of professional artists, which has proved a most useful unit, since it
is necessary that the work done should deceive not only the human eye,
but the sensitive plate of the camera.




CHAPTER IV

COMPOSITION AND USE OF THE ARTILLERY

  1. Retrospective view. General considerations.

  2. Different sorts of artillery: Artillery of an Army; Artillery
       of an Army Corps; Artillery of a Division; Trench artillery
       “Tanks,” or artillery of assault.

  3. Mission and use of the artillery during a battle.

  4. Anti-aircraft artillery.

  5. Advance or withdrawal of the batteries.

  6. Conclusion.


=1. Retrospective view.= _General considerations._ In the French
army long before the war, several clear-headed and well-informed men
had foreseen the necessity of having a large, heavy field artillery,
similar to that of Germany.

To recall General Pétain’s motto: “The artillery conquers the
positions, the infantry occupies them”--this simple axiomatic statement
obviously compels the inference that an army shall possess an artillery
able to bombard efficiently every species of fortification.

Unfortunately few people in the Government or parliamentary spheres
could be brought to consider the possibility of a war; so this question
of a heavy artillery, although continually agitated in those circles,
remained unsolved.

In 1914, the immense majority of the French nation, including not only
the politicians but also a great many army officers, scoffed at the
possibility of a war with Germany. The Moroccan imbroglio, the war in
the Balkans, and the Austrian policy of conquest were not sufficient
warning for them. That France’s military preparation was entirely
inadequate, and that this was due solely to the lethargy of the
national mind, is generally admitted to-day. During the first year of
the war, not only were we hopelessly outclassed in heavy artillery, but
at Lille, Maubeuge, and La Fère the Germans captured a goodly number
of our heavy guns with their munitions, and turned them against us.
Fortunately we are able to assert that they used them with very little
advantage to themselves.

Only a few heavy-artillery regiments existed before the war. Their
armament included few quick-firing 155 mm. Rimailho guns, which, though
rapid in action, were too short in range. Other batteries were armed
with 120 and 155 mm. siege guns; good types, but too small in calibre,
and too slow in action. Moreover all these guns were placed at the
disposal of armies which, at the beginning of the conflict, considered
them as a reserve stock and kept them too far from the battle-fields of
August and September, 1914.

The impossibility of following up the victory of the Marne gradually
opened the eyes of the Government to the need of a very large, heavy
artillery, but this necessity was frankly admitted only in the autumn
of 1915, and then largely under the influence of the example given by
our British Allies. They had much more quickly comprehended that no
victory would be possible unless supremacy in artillery was achieved,
and, with their usual cold determination, had turned all the resources
at their disposal to the manufacture of every kind of gun, and
mountains of ammunition.

France followed the example.

The progress made enabled us first to hold our own against the German
artillery, then to equal it, and finally to surpass it.

Considering the limited means left to France by the invasion,
considering the seizure by the enemy of her Lorraine iron deposits,
and of her richest coal mines, it must be acknowledged that the effort
made from 1915 to 1917 was gigantic.


=2. Different sorts of artillery.= We shall divide the artillery into
three parts: the artillery of an army, of an army corps, and of a
division.

ARTILLERY OF AN ARMY. This includes heavy artillery of all sizes. The
army unit alone possesses guns of greater calibre than 155 mm. The
composition of the heavy artillery in an army varies considerably,
the number of different types of cannon allotted to any one arm
depending upon circumstances and on the work which it is expected to
do. According to local needs, therefore, the Generalissimo orders the
heavy artillery to be transferred from one army group to another.
Similarly, the Chief of a group of armies can, as he sees fit, order
such transfers of guns within his command.

We find in the armies howitzers and mortars of the following sizes:
220, 270, 280, 305, 370, 400 mm. (in inches: 8, 10, 11, 12, 14½, and
15¾). Soon we shall have 520 mm. guns (20½ inches). There are also
field guns of 120 and 155 mm. short and 155 mm. long (5 and 6 inches)
and naval guns of 19, 100, 240, 274, 305, and 340 mm.

The artillery of an army is under the command of a General.

The field batteries of 120–155 mm. are composed of four pieces;
howitzer batteries and naval batteries of 100 and 190 mm. are nearly
always of two pieces. The largest mortars, and the heaviest naval guns
mounted on railroad trucks, operate singly, and each gun is accompanied
by several trucks carrying its material and munitions.

ARTILLERY OF AN ARMY CORPS. The artillery of an army corps is under
the command of a Colonel. It includes two groups of 75 mm. field guns,
two groups of 105 (4 inch), or of 120 (5 inch), and one group of 155
(6 inch), quick-firing. This artillery is reinforced, in case of need,
by the heavy artillery which the army can dispose of. The Colonel
commanding the artillery assumes the command of all batteries, of
whatever size, momentarily put at the disposal of his army corps. He
is most specially intrusted with the selection of the ground on which
to place the batteries, and it is he who has to specify the part each
of them shall take in the action. The divisional batteries of the army
corps are also under his command, at least during the preparation for
the attacks. It is absolutely indispensable that each battery should
be assigned its objective, and should be positively forbidden to
scatter its projectiles promiscuously. Thus costly waste is avoided,
and a definite purpose accomplished.

While getting ready for their first great attack in the Somme sector,
the British, during an artillery preparation of several days’ duration
that exceeded in intensity any previously known, fired a vast number of
projectiles. At the time of the assault, the British infantry displayed
an indomitable courage, and captured several important positions, but,
for the want of a proper concentration of the fire of their artillery
on the points to be destroyed, their heavy losses in men were too big
a price to pay for the gains they made. The British artillery has
since modified its methods, and, assisted by an unexcelled service of
aviation, it has, over all its Front, impressed the Germans with the
power and accuracy of its guns.

ARTILLERY OF A DIVISION. At present, divisional artillery includes
three groups of 75 mm. (each group composed of three batteries of four
guns), one group of three batteries of four quick-firing 155 mm., and
one battery of trench-guns, the number and size of which are variable.
This artillery is under the command of a Colonel.

Further on we shall speak of the difficulty experienced in advancing
the heavy guns through the country devastated by the Germans in March,
1917. The 75 mm. field artillery, only, was able to advance quickly
enough. Guns of 105 mm. should have been able to follow the troops
everywhere and give them help until the arrival of the heavier pieces.

In position, and at the time of active operations, the artillery of a
division is reinforced by the artillery of the army corps and that of
the army.

The longest range of field guns is 8500 metres.

The range of the howitzers varies between 10,000 and 14,000 metres.

Heavy guns have a much greater range. The 380 we shall soon be turning
out will send a shell containing 150 kilograms of explosive to a
distance of 38 kilometres.

TRENCH ARTILLERY. This artillery includes special mortars, firing
at a high angle projectiles containing powerful explosives; their
longest range is not over two miles. They are principally used for the
destruction of wire entanglements, first-line trenches, and dugouts.
Their size varies from 58 to 340 mm.

The projectiles are provided with blades which maintain their
direction through the air, as the guns firing them are not rifled.
They are really aërial torpedoes, and are tremendously destructive to
trenches and defences of every sort.

The armies have a big reserve of trench guns distributed along the
Front according to circumstances. These batteries are generally placed
in the first-line support trenches.

Small-sized mortars operated by compressed air are now also used. Their
range is limited, but for short distances they are very reliable and
powerful weapons.

By reason of the great difficulties they experienced in getting heavy
artillery up into the mountains the Italians have adopted trench
mortars which fire very large projectiles to a considerable distance,
and they have succeeded in constructing some examples which will throw
heavy torpedoes three and four kilometres.

“TANKS” (ARTILLERY OF ASSAULT). Tanks were first used by the British,
to whom they have rendered very valuable service. They have not only
been of great assistance to their infantry, but have also produced a
very depressing effect on the enemy’s morale.

Their somewhat too great weight caused many to stick in the muddy and
unfavourable ground over which they had to operate. We believe that
the original model has not been abandoned, but that lighter ones have
lately been built.

The French made use of tanks for the first time in their attack on the
Aisne on the 15th of April, 1917. Their machines were not absolutely
perfect then, and, owing perhaps to faulty tactics, their success was
not equal to expectation, but, in the attack of May 5th, they were
better handled and proved valuable in the action. The French tanks have
since been improved, and now thoroughly fulfil their purpose.

It is important to note that the Germans, who for a long time did
not favour the adoption of tanks, probably because the management of
these monsters require of their crews qualities not always found among
the Boches, have recently constructed some. Of course they are of
“Kolossal” proportions. We do not know as yet exactly what results they
have obtained.

Quite recent reports reveal that in the attack of the 28th of October,
north-east of Soissons, the French used tanks far lighter than those
first employed. Last spring’s experience has caused them to be handled
in a much more efficient manner, and the first reports show that these
machines, by destroying numerous machine-gun shelters that had escaped
the fire of the artillery, have greatly facilitated the forward march
of the troops.

It seems to us that the proper tactics for tanks should not be to
advance ahead of the infantry waves and thus, without benefiting them,
hinder the barrage fire of their own artillery, but should consist
in following slightly behind the first waves in order to complete
the destruction of the numerous nests of German machine-guns which
the artillery has not always succeeded in silencing, to overthrow
obstacles, and flatten the incompletely destroyed wire.

In brief, the mission of the tanks should be to support the infantry
and clear the way for its forward progress.


=3. Mission and use of the artillery in the fight.= The mission of the
field artillery in the preparation for an offensive consists in tearing
up the first-line trenches, the passages of communication, and the wire
entanglements, and in locating and silencing the machine-guns through
the loopholes of their shelters.

Unless the field artillery is directed with most particular care, it
is liable to expose its infantry to heavy losses, which are not only
regrettable in themselves but affect considerably the morale of the
troops.

For the very reason that the 75 mm. gun is a weapon of great precision,
its accuracy is disturbed by very slight causes, such as atmospheric
perturbations, and the quality and condition of the different powders.
The officers commanding the batteries, immediately upon their arrival
in new regions, prepare firing-tables based on the local conditions of
the atmosphere and temperature, to guide the firing at the different
hours of the day. They correct also the errors resulting from the
different propulsive qualities of the various powders. As a rule all
the projectiles belonging to the same lot give similar results.

Directly it is in position, the field artillery calculates the distance
that separates it from the various points on which it may have to fire.
It complies with all the requests of the infantry, when informed of
dangerous moves of the enemy; executing rapid barrages on the signalled
objectives. By barrages, at about one hundred metres ahead of the
advance, it protects the assaulting waves of infantry. It increases the
range in proportion as the advance moves on. The groups of 105 mm. may
be advantageously used in order to reinforce the action of the 75 mm.
field artillery.

Since it has been possible to increase the proportion of 155 mm.
quick-firing guns, batteries of this calibre have often been brought
in to reinforce the barrages kept up by the 75 mm. guns. In the recent
operations on the Anglo-French front this combination has often been
used on a large scale, and with disastrous effect whenever fire was
opened in time on troops assembled for the purpose of counter-attack.

Heavy artillery has a twofold part to play. It is an artillery for
destruction and an artillery for counterfiring; it executes also
neutralizing fire. It is guided by the information furnished by
scouting airplanes and captive balloons.

_Destructive fire_ is executed against important dugouts, blockhouses,
shelters for machine-guns, and everything on the enemy’s front that can
check the advance of the infantry.

_Counterfiring_, guided by the same agencies, is executed in order to
put enemy batteries out of action. It is certain, indeed, that the
one of the two adversaries that succeeds in silencing the opposing
artillery can more easily collect his forces, and, at the time of
launching an attack or resisting a counter-attack, the task of the
infantry will be made easier of accomplishment.

At the time of the preparation of the attacks, the fire of the various
artilleries continues for seven and even eight days with unabating or
even (if necessary) increasing intensity.

_Neutralization fire_ is made with asphyxiating shells. When the
enemy’s batteries have been well pounded by destructive fire, the
quickest way to put them completely out of action is to exhaust the
gunners by neutralization fire and thus prevent them from serving the
guns. Even with gas-proof masks the men very soon become exhausted on
account of the difficulty they have in breathing through them. With
this end in view, a bombardment with asphyxiating shells is kept up for
several hours.

For instance, at the time of the attack, near Craonne, on the 5th of
May, 1917, one of our French army corps was faced by about one hundred
and eighty German batteries of all sizes. Our destructive fire had
terribly damaged those batteries; but the Germans, being undisturbed on
their Eastern Front, could bring up fresh batteries at every moment,
and were still able to oppose our advance towards the tableland of
Craonne.

On the whole length of our Front our artillery fired with asphyxiating
shells, and a few hours afterwards, with the exception of four or five,
all the German batteries had ceased firing.

The importance of the use of asphyxiating shells may be very great.

Recently in Champagne an asphyxiating shell of large size penetrated
through a hole made by previous heavy shell-fire into a concreted
German tunnel and exploded. This tunnel, which sheltered an important
garrison, comprising two companies and many machine-guns, had already
suffered heavily. Its exits were obstructed, but it was still holding
out.

All but one man were suffocated, surprised by the gas before they had
time to put on their masks. A French surgeon, peering through the
hole made by the shell and seeing no sign of life, crept into the
corpse-filled gallery, and, after a brief reconnoissance, signalled to
the nearest French troops that they could occupy it.

It is not unusual to see, during the big attacks, the various
artilleries established in eight and even more rows, occupying all the
available vantage ground.

The occupation of Hill 304 in August, 1917, is a striking example of
the results of a thorough co-ordination of the different elements for
the preparation of the attack and the capture of the position.

Commencing with the systematic destruction of the enemy’s defences by
several days’ continuous bombardment, accompanied by a most careful
location of his batteries, with the help of all possible means of
investigation (such as wireless telegraphy, photography, location
of the guns by light and sound, interception of code signals,
interrogation of prisoners, etc.), the guns of our counter-batteries,
having duly apportioned these various objectives, succeeded on the
morning of the 24th in neutralizing the fire of the German artillery,
and exhausting the defenders of Hill 304.

At the time of the attack our battle-planes, by driving the enemy’s
aircraft far beyond their lines, allowed our scout-planes to direct
accurately the fire of our 75 mm. guns, and permitted the aircraft
accompanying the assaulting waves of infantry to fly close to the
ground and attack the enemy in their very trenches.

To such a co-ordination of all our efforts is due the seizure, with a
minimum loss to our troops, of most important positions.

The Germans have a way of attempting to regain lost ground by
counter-attacks in mass-formation, which has cost them terrible losses.
Field artillery has a capital part to play in the repulse of these
attacks, which are usually broken up by the rapidity and power of
the barrages. The guns of 75 mm. are assisted by the groups of 105
and by the destruction groups of 155, and also by counter-battery
or neutralization fire from the heavy artillery, according to the
necessities of the moment.


=4. Anti-aircraft artillery.= Airplanes are the most reliable and
effective weapons against airplanes and Zeppelins, but it is impossible
to command at all times a sufficient number of machines to prevent the
enemy’s incursions.

Behind the lines have been placed special sections of anti-aircraft
guns of different sizes (75, 47, and 37 mm.) mounted on special
carriages that allow vertical fire. Without entering into details, we
may say that the fire of these guns has been rendered so accurate that,
though every airplane thus attacked may not be destroyed, projectiles
shower so close around them that they are forced to fly away at all
speed. A certain number of aircraft are brought down by these guns
every month.

One of these sections hit and brought down a Zeppelin near Verdun in
February, 1916; another shot down, near Compiègne, in the spring of
1917, a large Zeppelin on its way back from England. Quite recently
five Zeppelins returning from a raid on London were brought down
in France by airplanes and anti-aircraft cannon. We mention these
well-known events as indicating the unquestionable superiority of
the airplane over the dirigible, which, we repeat, has been of real
military service only at sea. They also demonstrate that by increasing
the number of anti-aircraft sections both behind the front and in
proximity to the whole enemy line, the raids on open towns can be
rendered impossible.

The Germans have recently invented a new gun, probably a mortar, which
projects with great accuracy and to a high altitude a big cluster of
whirling balls of fire, each having a potential diameter of five or six
feet of fire. The whole cluster has an apparent radius about as great
as the spread of an airplane from tip to tip. These new projectiles,
known as “flaming onions,” have been used principally on the British
Front, and do not appear to have done much actual damage, but should a
great number of them be discharged at large, slow-moving planes, they
might become dangerous.

ARMOURED MOTOR-CARS. On some armoured motor-cars small cannon are
used; on others, machine-guns are placed. They are intended to throw
the enemy lines into confusion at certain points. Their action must be
swift, sudden, and brief. Their mobility enables them to dodge the fire
of the enemy’s artillery. These cars can be much more useful in open
field operations than in trench warfare. They will be especially useful
as a help to cavalry when the latter can once more be used.

Every regiment of infantry is now provided with a section of three
37 mm. guns which being light, easy to move, and very accurate are
employed principally, either all together or in the proportion of
one to each battalion, against machine-guns. They have been greatly
appreciated by the regiment commanders; a large number will probably be
distributed as soon as they can be manufactured.


=5. Advance or withdrawal of the artillery.= One of the most
interesting questions for an army in the making, such as the American
Army, is that of the rapid moving of the heavy artillery, at a given
moment.

We do not hesitate to say that this problem is far from being entirely
solved on the Western Front, and that its study and organization will
be a very hard task for the engineers entrusted with its solution.

American engineers will have to go to the Western Front and see for
themselves all the difficulties to be surmounted.

ADVANCE. During the spring of 1917, the French Army had to pursue on
a large front an enemy who had not only devastated the country behind
them to a depth of from 30 to 35 kilometres, but had also accumulated
in this wilderness all the obstacles their fertile imagination could
suggest.

The 75 mm. field artillery alone, at the cost of great efforts and
tremendous loss of horses, managed to overtake, though somewhat late,
the advance of our infantry, which had succeeded in going forward
everywhere.

The sections for the supply of munitions followed their batteries,
but more slowly; and some batteries, which at the cost of great and
continuous efforts, had come into position, had no munitions.

The only way to guard against such delays, in the future, will be to
keep in reserve complementary teams of horses, to replace those that
are killed, or to help the batteries and their ammunition sections
through the worst passages.

We have not the right to give here in detail the difficulties
encountered in the advance of the heavy artillery. We were informed of
them by a confidential note from the High Command.

However, while this confidential note sets forth in detail all the
difficulties encountered, it makes no recommendation whatever as to
what should be done on such occasions in the future.

There is absolutely no doubt that wherever the Germans retreat, they
will endeavour to accumulate obstacles behind them as they did on the
Somme and the Aisne. The question of the advance of the different
artilleries must therefore be very carefully considered. Means must be
found to ensure it, while keeping within the immediate reach of each
battery the requisite munition supply.

America, however great her participation in the war, will never be
able to mobilize more than a small part of her immense population.
Unlike France, she will not be forced to suspend the activities of
ordinary industrial and commercial life. Assisted by technicians,
she will succeed in training all the special troops required and in
supplying them fully with material. She will even be able to lend
some of them to France, who, having mobilized all her fencible men
for service at the front or rear, experiences great difficulty in
recruiting the technical troops she needs.

The problem of the rapid advance of the artillery is to be solved
by increasing the road-making facilities. Whatever the difficulties
encountered and the obstacles created by the enemy, we must be able
to make, with the least possible loss of time, large and solid roads
in sufficient number, and to repair or build entirely new lines of
railroads of all gauges.

WITHDRAWAL. We must always foresee the possibility of a defeat, prepare
everything to lessen it, and leave as few guns as possible in the hands
of the enemy. This problem is easier to solve than that of an advance
towards the enemy, and in order to be able to withdraw the various
artilleries rapidly, it will be sufficient, when preparing the attack,
to have foreseen the number of roads and tracks necessary to remove the
batteries from the front.

These roads and railway lines have to be constantly kept in order by
special gangs, and the holes made by shells must be immediately filled
up.

In fact we shall see that the perfect repair of all these ways of
communication is intimately connected with the supply of munitions.


=6. Conclusion.= From the mere general outlines we have just given
concerning the use and mission of the artillery, we may draw the
following conclusion:

Till the end of the war it will be necessary to constantly increase
the manufacture of guns of all sizes, especially those of the largest
calibres, and to accumulate a reserve of ammunition far beyond the
actual needs. The adversary that will have succeeded in silencing the
opposing artillery will be sure of victory, and will obtain it without
the enormous losses in human life that all combatants have sustained
since the beginning of the war.

These losses, it may be remarked in passing, have been considerably
reduced of late by the employment of more scientific methods of
fighting.

The transference of heavy artillery from one army to another, according
to local needs, has many disadvantages. Such a practice prevents the
High Command from deceiving the adversary as to the real point of
attack. If the artillery preparation could be maintained with equal
intensity for equal periods of time on the Fronts of several armies,
the enemy could not possibly foresee which of the armies would strike
the principal blow, and would be much embarrassed as to the disposition
of their reserves.

It will never be possible on a 600 kilometre front to accumulate
a sufficient number of guns literally to accomplish this, but by
constantly turning out new guns, by increasing the number of batteries
and of large artillery concentrations on many points distant from one
other, the enemy will be kept guessing.




CHAPTER V

MUNITION SUPPLY

  1. Sketch of the railroad organization.

  2. Organization of the munition parks.

  3. Divisional parks. Their organization. Their management.

  4. Importance of the munition supply.

  5. Replacement and repair of guns.

  6. Different issues of ammunition.


In the present war the supply of munitions of all kinds is of such
great importance that we have thought proper to devote a special
chapter to this subject.


=1. Sketch of the railroad organization.= According to instructions
from General Headquarters the services at the rear forward the required
ammunition to the “distributing stations” of the different armies.
There is one of these for each army, provided with the necessary
sidings and yards where all the men and materials coming from the rear
are sorted, and distributed further ahead throughout the “terminal
zone” (_zone d’étapes_) or “war zone.” This zone extends from the
distributing station to the front of the army it supplies. The stations
within the zone at the rail-heads, just behind the front, are the “war
terminals” (_stations têtes d’étapes de guerre_).

From this brief sketch of the railroad organization that feeds the
front, we pass to a consideration of the war-freight which it carries.


=2. Organization of the munition parks.= At the rear of every
army there is a “Main Artillery Park,” located at a point of easy
communication with the distributing station and the front beyond.
Military railways connect it with the “Army-Park Depots” farther on,
which in turn are similarly connected with the “Army-Corps Parks,”
and the latter with “Divisional Parks.” The military railways thus
spread out fan-wise from the various bases to the front, through
distributing-point after distributing-point.

During the transportation of the munitions from the interior of the
country to the front, the different kinds of projectiles are never
mixed together. There are munition trains for heavy guns, others for
field guns.

The munitions are transported by rail in the following way. The 75
and 105 shells travel in wooden cases, from which they are removed
only to be placed in the supply wagons that carry them directly to the
batteries.

The shells for the big guns are transported in bulk. They are filled
with explosive, but the fulminate is not attached.

The powder lots for all sizes travel in _copper cases_, to guard
against all risks of accidental explosion. The distributing station
sends the ammunition trains to the Main Parks, where they are shunted
on to sidings.

These trains are afterwards distributed to the advance posts of the
Army Parks, where, according to circumstances, they are unloaded to
form reserves of munitions, or redistributed to the Army-Corps Parks.

Most of the time, when the parks of the front are demanding fresh
supplies, those trains are not unloaded at the Army Parks, but sent on
to the Army-Corps Parks.

There, the ammunition is taken off the cars, and piled in assorted
stacks separated by intervals of fifty metres; stacks of cases for the
field artillery, stacks of big shells, stacks of fulminate cases, and
stacks of powder-bag cases.

The Army-Corps Parks are entrusted with the supply of the Divisional
Parks, with which they are connected by small railways of 60-centimetre
gauge.


=3. Divisional parks.= As we have taken the division as a unit and
examined its component parts, we shall likewise take the Divisional
Park as a type.

It has complete autonomy, and has the means of distributing munitions
for the artillery and the infantry to the batteries and regiments of
the division. It possesses, too, reserve guns, and has the equipment
necessary for repairing wheels, wagons, gun-carriages, brakes,
motor-cars, etc.

Let us examine the part taken by a Divisional Park in the preparation
of an action.

As it is continually supplied by the Army-Corps Park, its duty is the
maintenance of a sufficient reserve for the batteries and regiments of
the division. The reserve should be complete when a battle is about to
begin.

Field artillery and infantry should be supplied with munitions by
wagon-trains. In fact, as soon as the soil has been badly ploughed
by shells, only horse-drawn vehicles can circulate. The frequent
necessity of planting new batteries has been the cause of a
considerable reduction in the number of the wagon-trains. They have
been replaced by motor-cars that drive as near the batteries as
possible. The latter then send their wagons to meet the motor-cars and
bring the shells to the points selected by the officer commanding the
batteries.

The ammunition for the heavy artillery is brought on railways
of 60-centimetre gauge to the battery supply-shelters, whence
40-centimetre gauge tracks, equipped with small hand-trucks specially
detailed to each battery, take it directly to the guns. These
supply-shelters, solid enough to resist the enemy’s shell-fire, are
constructed by each battery as soon as it has completed and occupied
its allotted emplacement.

During the preparation the transportation of supplies offers few
difficulties so long as the fire of the enemy is not very severe.
As soon as the ground begins to be torn up, construction-gangs must
be summoned for the purpose of keeping in repair all the ways of
communication. Each battery has its own organized reserve of munitions
or supply-shelter, from which to draw the necessary shells during the
first days of the operation, and the parks endeavour by all possible
means to keep on feeding these reserves.

Ammunition for the trench-guns is conveyed to the entrance of the
trenches by similar little hand-operated railways, and cartridges and
grenades for the infantry are distributed in the same manner.

It is advisable, when time and means permit, to operate these small
railways of 40-centimetre gauge in the trenches themselves, when they
are sufficiently wide for the purpose. The small trucks, pushed by
men, will bring the torpedoes and other munitions as far as possible,
but when the narrowness of the excavations prevents this, supplies
must be carried by hand to the most advanced lines. This work, which
is very laborious, should be left, whenever possible, to men drawn
from regiments in the rear which are not intended to take part in the
impending attack. For the last year North African burros have been used
for carrying the munitions through the communication trenches. They are
hardy animals, easy to drive, and they save the troops a great deal of
labour.


=4. Importance of the munition supply.= To give our readers an idea of
the enormous work involved in munition transportation, we append some
figures obtained from a field battery operating in the first lines on
the Aisne in March and April, 1917.

On the 12th of April the reserve in munitions of that four-gun battery
was 2000 shells per gun; _i. e._, 8000. From the 15th onward the
battery received 1500 shells daily. On the 19th, in the evening, there
remained only 1700 shells. The battery had therefore fired from the
12th to the 19th about 3600 shells per gun. This is a normal figure,
and explains why millions of shells are fired on a large front in a few
hours.

PRECAUTIONS. The enormous quantity of projectiles and supplies of all
kinds in the different parks prevents them from being sheltered or even
concealed, and, in order to limit the accidents caused by explosions,
the stacks of ammunition are far from one another. In an effort to
hide them from the enemy aviation, painted cloths, or green or brown
coloured grasses, are thrown over them, so as to deceive the eye.

For some reason or other the aviation of the enemy has not caused
very great damage to our various ammunition stores. The damage, as a
rule, has been confined to the explosion of the stacks directly hit,
although, at the beginning of the operations on the Somme, a German
aviator succeeded in destroying completely in the rear of the English
lines a large park of all sorts and sizes of shells.

The Allies also have often caused the explosion of German munition
depots, but the damage done, to all appearances, has always been
limited.


=5. Replacing the guns.= We have just seen that some field guns fire as
many as 3600 shots in a few days. This, added to the rapidity of the
firing (at times fifteen shots a minute, during barrages), explains the
rapid wear of the guns, whose metal becomes decomposed by the heat.

In spite of the quality of the steel, the guns wear out and finally
burst. It is of the utmost importance to replace those put out of
service by wear, or by the fire of the enemy.

This duty rests with the Divisional Park, which must have a reserve
sufficient for all needs. The park must also be prepared to repair all
the guns which are not so badly injured as to require shipment back to
the Army Park.

The battery to whose consumption of munitions we have previously
referred had, from the 12th to the 19th of April, to make the
following changes:

Two guns were put out of service by the fire of the enemy;

One gun exploded;

Seven guns had to be sent to the parks for repairs to their mechanism
or their carriages, which had been put out of service.

When the mechanism, the wheels, or a part of the carriage only have
been damaged, repair is rapidly made, but when the guns have exploded
or have been smashed by the enemy’s fire, they have to be recast.

In short, a battery of four guns, used ten guns in seven days; but it
should be noted that out of these ten guns only three were entirely put
out of service (two of the carriages could be used again) and two of
the guns merely needed a change of tubes.

Nevertheless, these figures emphasize the need for the parks to keep on
hand a large stock of reserve guns and to maintain workshops for the
immediate repair of slightly damaged pieces.

The retubing of the guns is a work that can only be done in the
factories of the army. The interior rifled tube, while white-heated,
is removed and replaced by a new tube which is re-rifled. The gun is
then as good as new, but, if the outside tube, which is the resisting
part of the cannon, has been broken by projectiles, the gun is beyond
repairing and has to be sent to the rear to be recast.

Under the most severe bombardment the replacement of the guns, thus put
out of service, did not take more than two hours.

The study of the above details will show the necessity, in case intense
and constant firing is needed, of accumulating the largest possible
reserve of field batteries at the points requiring a great effort.
When, as will often happen, several batteries are temporarily out of
action, the surrounding batteries will have to intensify their fire.
Barrage fires, almost exclusively the work of the field artillery, must
be rapid, continuous, accurate, and concentrated.


=6. Different issues of ammunition.= In order to avoid delay in the
aiming and firing, it is indispensable to see that the ammunition
brought to the batteries, of all sizes, belongs, as much as possible,
to the same issue, from the same loading factories. This rule is
strictly adhered to, except in case of material impossibility.

In France, parks generally receive lots of 5000 shells, all loaded in
the same factory and with labels enabling the gunners to ascertain that
the projectiles belong to the same lot; loaded at a specified date and
at a specified factory.

After a few trial shots, the battery commanders will see the effects of
a given lot of shells and point their guns accordingly.

We cannot enter here into the details of artillery practice. The study
of it must be begun in schools under the direction of specialists;
practical application must be made in the camps. This detailed
instruction is now being given in the camps of France and America to
the new recruits by Allied officers, who all have acquired at the Front
a large experience in all that concerns the artillery.

Guns play a preponderating part in the present war, and the combatants
are improving them unceasingly.

At the present time, the French field artillery undoubtedly stands
first for the accuracy and efficiency of its guns and projectiles, the
models of which have been adopted by the United States.

The French and English heavy artilleries are now decidedly and in
every respect superior in quality to the German and are more cleverly
handled.

The English heavy artillery, at all times seconded by numerous aviators
of great daring, can develop its concentration fires to a very great
degree of intensity and efficiency, and we can assert on personal
information that there never has been on any front during this war such
a formidable drumfire as that executed by the French artillery between
the 18th and 22d days of October, 1917, north-east of Soissons.

The Germans, who at the beginning of the war were rather bad gunners,
have improved their material and especially their firing methods by
frankly adopting those of the French artillery. They possess a heavy
artillery, as numerous as powerful and varied, and when they succeed in
systematizing their fire, its effects are cruel.

For this reason we shall end this chapter by repeating:

Let us have still more cannon, still more ammunition, and still more
airplanes to second our artillery.




CHAPTER VI

INFANTRY

  1. Arms of the infantry: the rifle; the machine-gun; the
       machine-gun rifle; the bayonet; the grenade; the trench
       knife; the automatic pistol.

  2. Instruction of troops. Duties of officers. “Shock-troops.”

  3. The infantry of a division: the front; dispositions taken;
       storming troops; occupying troops; offensive or defensive
       engagements; preparation of attacks; prolonged engagements;
       posts of command; signalling; battalions and companies;
       subaltern staffs.

  4. A word about cavalry.


=1. Arms of the infantry.= This war has completely transformed the
armament and consequently altered the fighting methods of the infantry.

RIFLE. In 1914 the French soldier was armed with the rifle of the 1886
pattern, not remodelled; _i. e._, a repeating gun with a hand-filled
magazine. It was an excellent weapon in use for a long time, but too
many of them had lost their accuracy through wear. Since 1914 these
rifles have been replaced by others of the same model fitted with
loading clips.

MACHINE-GUNS. At the beginning, the number of machine-guns was six per
infantry regiment. During a long time they were distributed at the rate
of two per battalion; then it was decided to form them into a battery
under the command of the Colonel.

This limit of six machine-guns per regiment placed France in a very
great inferiority to the Germans, who had reserves of machine-gun
companies in every division.

The first battles showed the important part played by the machine-guns,
and France prepared to turn out quantities of them. For a long time,
however, she remained in a state of inferiority in this respect, by
reason of the advances in equipment made by the Germans, and also
because, out of the three different models adopted and constructed,
two were not strong enough to stand trench warfare. These models gave
disappointing results, but the evil has now been remedied.

Each machine-gun company is now provided with sixteen guns--a number
which, we believe, has been adopted for the machine-gun company in
America. As France now possesses excellent models, the United States
troops, who already before the war had good guns, will doubtless
receive an efficient equipment. In this war, it is necessary that the
component parts of a machine-gun and its ammunition should be easy of
transport.

Notwithstanding their reduced effectives, the Germans are still able
to increase the number of their machine-guns, and they contemplate
raising their number from twenty-four to thirty-four per company. In
all likelihood the Allies will very soon have to strengthen their own
machine-gun batteries. A battery can seldom fire all its guns at the
same time because they get too hot after shooting about five hundred
rounds, and because they are likely, especially when operating over
muddy ground, to get jammed, and thus remain out of service until the
gunners can put them in working order.

For these reasons the ante-bellum regulations prescribed that
machine-guns should work in pairs, so that one would always be ready to
take up the fire, if the other should, for any reason, go out of action.

This regulation is still adhered to, but only so far as circumstances
permit. In cases of emergency, for instance, when an attack has to
be repulsed, the simultaneous use of all the guns becomes necessary,
especially against an enemy who possesses a superior number of similar
guns.

Each belligerent has captured many machine-guns and much ammunition
from the enemy. Thus France has complete German batteries, and Germany
possesses both French and English batteries.

The principal structural difference between the German and French
machine-guns consists in the mechanism for cooling off the guns; the
Germans use for this purpose water circulation, and the French air
circulation.

To avoid serious burns resulting from contact with the barrels of the
guns, the gunners wear gloves covered with very thick steel mail.

We have seen photographs of American machine-gun batteries carried on
motorcycles. The French no longer make use of this method, and although
it may have proven excellent in Mexico, it is entirely impracticable on
the French Front.

The ground for a long distance behind the lines of defence has been so
torn up and rendered impassable by prolonged bombardment that motor
vehicles cannot get through. Horse-drawn vehicles can approach much
nearer but at the entrance of the communication trenches even pack
transport has to be abandoned, and from this point (in default of such
recent devices as narrow-gauge hand-operated tracks, or pack-donkeys)
all war material has to go forward to the advance lines on men’s backs.
In case of an advance beyond the front, difficulties would be doubled,
since the devastated ground behind the enemy’s lines would have to be
traversed.

Pack transport therefore is best suited for machine-gun batteries and
their supplies. Where the number of horses or mules is insufficient,
light vehicles, each drawn by a single animal, can be used; especially
for the machine-gun sections which are to occupy more or less permanent
positions.

In order to counterbalance her losses, Germany has constantly increased
the number of her machine-guns, using them as a defensive weapon to
check the advance of the enemy, and to enable herself to cling to her
positions with a small number of men.

Germany does not hesitate to sacrifice machine-guns in order to gain
time, and German machine-gunners were often found in their shelters
chained to their guns, and so obliged to serve them until killed or
released by the enemy.

Machine-guns and grenades are certainly the most powerful arms against
assaulting waves. Seldom will the reconnoitring airplanes detect all
the numerous machine-gun shelters. Some of them always remain after a
bombardment to show activity at the time of the infantry attack.

The British have very efficiently used their tanks for the destruction
of these remaining machine-gun posts. The French have commenced to
use them advantageously. The Americans, entering the war after they
have been perfected, and profiting by their Allies’ experience, will
be able, on their arrival at the front, to use well designed and
constructed tanks in support of their infantry. Tanks will become more
and more indispensable weapons, and their general use will save the
infantry heavy losses of life. The Germans now have some.

MACHINE-GUN RIFLE. A new weapon was added to the armament of the
infantry in 1916. It is the machine-gun rifle, which is not to be
confounded with the automatic rifle (repeating rifle).

Much lighter than the machine-gun, carried and served by one man only,
it is easily moved about, and, when well used, is a most dangerous
weapon.

To shoot, the man lies down (behind a shelter if possible) and lifts
the butt-end to his shoulder, the fore-part of the gun resting on
a very short fork. Machine-gun rifles are used principally against
machine-guns.

There are several types of machine-gun rifles. The best is without
doubt that provided with a plate, containing twenty-five cartridges,
which turns on a vertical axis back of the gun and fires the
twenty-five cartridges. Each shot causes the plate to make 1/25 part of
a revolution and drop a new cartridge in the barrel. When the plate is
empty it is immediately removed and replaced by another that has been
previously loaded.

Experience shows that machine-gun rifles give good results only when
in the hands of cool and clear-sighted men, well acquainted with their
manipulation, but that they are not as good as the ordinary rifles in
the hands of African troops.

THE BAYONET. All the infantry use the bayonet, a weapon which has
maintained its full importance in the present war. French and
Russian soldiers handle the bayonet most dangerously. The Germans
are not so proficient in its use.

[Illustration: Urtebize

January 29, 1917--12.30 P.M.]

The men must be given a very detailed and thorough instruction in
bayonet practice, but as the American troops are in possession of a
very complete manual on this subject we will not dwell upon it.

GRENADES. A new weapon (or rather an old one that has been revived)
that plays a very important part in the actions of the infantry is
the grenade. Many types exist but they can be classified either as
offensive or defensive grenades. The former kind is not so destructive
as the latter. They are lighter, can be thrown to a greater distance,
and are used to prevent the enemy from coming out of their dugouts
and trenches when the assailants reach them. The defensive grenades,
which are extremely destructive, are used against attacking or
counter-attacking troops. Some are thrown by hand, others with the
rifle. Well trained soldiers can throw grenades as far as fifty and
fifty-five metres.

Rifle grenades are thrown by the propulsive power of the ordinary
cartridge. A special contrivance at the muzzle of the gun cocks the
grenade, so to speak, as it is driven from the barrel by the bullet,
so that it will explode on hitting the ground. It reaches farther than
the hand grenade.

Recently General Pershing rightly laid stress on the necessity of
perfecting the marksmanship of the recruits. To this accomplishment and
skill in the use of the bayonet, which gives the soldier self-reliance,
suppleness, and agility (qualities that the Germans do not easily
acquire) ought to be added a thorough training in the throwing of
grenades, a sport which promptly captivates those who practise it.
Excellent results are secured by offering prizes for grenade practice,
both for distance and marksmanship. The French soldier is contented
with little, and the mere offer of a few cigars or packages of
cigarettes to the best throwers has achieved wonderful performances in
this line.

We believe that the Germans have no reason to congratulate themselves
on having been the first to reintroduce the use of grenades in warfare,
because it is a weapon requiring intelligence and skill in its
handling. Thrown by shrewd quick Frenchmen, or by sportsmen like the
British, it is much more dangerous than in the hands of thick-headed,
passive German soldiers. We are sure that the American troops will use
the grenade with the same skill as their Allies.

TRENCH KNIVES. The trench-fight is a fight to a finish, and has
necessitated the adoption of a strong knife. In the hands of fierce
resolute men it is a terrible weapon, much resorted to in the confined
space of trenches, tunnels, and dugouts where bayonets cannot be used.
The African troops are very fond of these knives, and as the Germans
are well aware of this fact, they never surrender to African troops,
and the fights between these combatants always smack of savagery.

On account of their fear of knives and daggers the Germans have
pronounced their use inhuman, and have shot many prisoners on whom
daggers were found. It is advisable, then, for troops obliged to
surrender (and the bravest troops may have to do so) to throw their
daggers away in good time.

AUTOMATIC PISTOLS. Officers and non-commissioned officers only have
automatics, but we would like to see them issued to the infantry, as
they _are most useful in hand-to-hand fights_.

The use of the various arms above named has necessitated the division
of the company into grenadiers, machine-gunners, and light infantry.
The last-named fight especially with the ordinary rifles, bayonets, and
daggers.

When circumstances permit, it would be advisable to teach all the
men of a company the use of all the arms, one after the other, so as
to be able to re-establish after and even during a battle the exact
proportion of specialists. There has been too great a tendency to
neglect rifle practice. Soldiers ought to lose no occasion to perfect
themselves in the use of the rifle, which remains the principal arm of
the infantry. Its importance will be even greater in open warfare.


=2. Instruction.= To be a good infantry soldier a man ought to be very
vigorous, sufficiently young, not more than thirty-five, well fed and
well trained.

The individual instruction should be as thorough as possible, and
perfected before the man is sent to the front.

The theoretical instruction of troops must be completed before they can
be given the defence of a sector, and it is only in the lines and in
the face of the enemy that they can acquire the practical experience.
The more thorough their knowledge of theoretical details the sooner the
company and battalion will become good fighting units.

[Illustration: La Bovelle

December 20, 1916--3. P.M.]

The spirit of initiative should be specially encouraged in every
soldier, as in the present war every man has an individual part to
play, according to his duties, his rank, and his weapons. During the
actual fighting the soldier can rely but little on the leadership of
his superiors, who are merely expected to set the example, and who are
frequently the first shot.

DUTIES OF THE OFFICERS. Before ordering their men to advance and while
still in the trenches, the officers, assisted by their non-commissioned
officers, should, whenever time and circumstances allow, strive to
explain fully to every man what are the objectives to be attained and
what means are to be employed. No details should be neglected.

The Major’s duties will be to designate very clearly the fronts
assigned to each of his companies, the objectives they are to reach,
and the itineraries they are to follow. An assault is usually made in
several waves, so the order of departure, the distance to be maintained
between the successive waves, the place to station the reserves, and,
if need be, the instructions relative to the juncture and reforming
of the elements of the various companies, form so many points that
must be settled beforehand in their minutest details. The Major will
have to decide beforehand how the battalion as well as the several
companies will hold the objectives after capturing them, how they
will organize these objectives in the shortest time possible, and
how they will resist the counter-attacks. The officers in command of
battalions and companies must not forget that, once the action has
commenced, and often even before it is begun, all communications become
difficult and frequently impossible, and that consequently all possible
eventualities, within the orders received, must have been thoroughly
studied in advance. So it is indispensable to give every man minute
instructions.

This extract from a letter found on a French captain who was killed on
the Meuse will give to young and inexperienced officers a good idea of
the thoughts that must absorb the mind of an efficient commander.

“I am alone,” he wrote, “in this underground shelter, still permeated
with the foul atmosphere of the Germans, where the evidences of a
disorderly flight, biscuits, bloody rags, stained letters, a biography
of Hindenburg, etc., lie scattered in every direction. I am alone after
having relieved the company that made the attack. I am alone without
counsel if I hesitate, without help if I weaken, in this captured
trench which is half destroyed. My two hundred men are blindly piling
in, ignorant of their surroundings, of what to do. The sight of them
restores my waning energy. I have to think for them, and put everything
in order before daybreak. I consult my watch: it is midnight.”

Here is a Chief, a real leader! He goes out; until dawn he inspects
his sector, he sets his men at work. To each he assigns a task; he
stimulates them, prevents them from falling asleep, and does not spare
himself. He can count on all his subordinates to do their best, and at
the break of day, if the bombardment is resumed, if the counter-attack
is launched, the trench will be ready; the losses will be lessened;
resistance will have been made possible. It is by such methods, by
the constant co-operation of the officer and his men, that the army
performs marvellous feats. It is this constant co-operation, this
comprehension of duty by the humblest leader, that enabled us to hold
out at Verdun.

The most difficult missions should be entrusted to those known to be
the best qualified to fulfil them.

Once the signal of attack is given, the officers and non-commissioned
officers will scarcely have any other means of ensuring obedience to
their orders than by setting an example to their men.

We take this occasion to render a profound homage to inferior ranking
officers of the French armies. They indeed are and shall remain the
heroes of this war. They have fallen on the field of honour since
August, 1914, not by thousands but by tens of thousands. Never, under
the most critical circumstances, has their morale weakened for a single
moment. At all times, men equally as brave as their predecessors have
been found to fill the places of those who had so heroically (I was
going to say so cheerfully) gone down to death. By the sacrifice of
their lives to their country, they have not only set an example to the
officers of their Allies, but have also given the latter time to form
and train themselves, and I can truthfully say, to equal them. The
bravery displayed by the infantry officers of the English, Italian, and
Russian armies is on a par with that of the French officers, and within
a short time, the American officers, I am sure, will show themselves
worthy of the same verdict.

[Illustration: South of La Bovelle Farm

January 29, 1917--12.30 P.M.]

Our officers have always and from the very first day of the war
invariably marched ahead of their men, leading them straight to the
enemy. They have advanced through the most intense curtain-fire; they
have exposed themselves to the fire of innumerable machine-guns; they
have been the targets of rifles and grenades. Thousands have been
killed; not one has hesitated, not one has turned back. The Allied
officers have exhibited the same daring, the same bravery.

But what about the German officers? Is it possible not to contrast
their attitude with that of our own? The German officers endeavour
to keep under shelter as long as possible their precious persons, so
greatly superior, in their own estimation, to those of their men, and
when they do muster the courage to come out into the open, they are
content to follow behind their troops, with revolvers in their hands to
exact obedience.

We wish to reproduce here two or three citations taken at random among
a thousand similar ones published in the _Journal Officiel de la
République Française_, the official organ of the French Government, to
give a vivid illustration of the way that officers ought to understand
their duties:

On September 1, 1914, _Major Parisot de la Boisse_ said to his
chasseurs: “I give you my word of honour, as long as one of us remains
alive, the enemy shall not pass.” In spite of heavy losses, though
nearly surrounded, he extricated his troops and maintained the fight.
The Pass de Mandray he defended remains French!

_Captain Robert Dubarle._ “A living example of impassibility under
fire, contempt of danger, energy, and initiative.”

_Captain Mazarde_--11th Chasseurs. “A splendid officer already cited
at the order of the Division, of the Army Corps, and of the Army. From
June 29th to July 14, 1915, he exhibited the bravery of a hero. While
leading his Chasseurs to the air of _Sidi Brahim_ in an attack upon a
wood, he was stopped by wire entanglements at 50 metres from its edge.
He maintained the line of attack for 36 hours, face to face with the
enemy, repulsed a counter-attack, and riddled the line of the enemy
with bullets and grenades. He withdrew only when ordered to do so,
taking all his wounded and the bodies of the officers killed. He was
shot, and died from his wounds.”

[Illustration: West of Ailles

April 24, 1917--10.00 A.M.]

_Captain Pierre Mercier_--67th Battalion of Chasseurs. “Entrusted with
the mission of defending the passage of a bridge, he maintained his
company under an intense fire. Outflanked on both right and left, he
did not hesitate to charge an enemy very superior in numbers, and fell
mortally wounded, saying to his men, “We have done our duty.”

Space does not allow us to give more numerous citations, but we think
that it would benefit the American army to get the minutes of the
war, to select therefrom the most brilliant citations of the French
and English armies, to have them translated and widely distributed
among the American troops. Nothing would be more instructive for the
officers, nothing could better rouse their fire, nothing would inspire
them with a greater desire to emulate their comrades in the Allied
armies. The example of heroism is contagious for young men.

SHOCK-TROOPS (STOSSTRUPPEN). The continual failure of the German
attacks or counter-attacks for more than a year led them to the
creation of what they call _Stosstruppen_. The new recruits of the
German army were lacking greatly in quality--the German soldier at best
is wanting in initiative. The High Command therefore resorted to a
selection of the best elements to be found in some of their divisions,
with which to form battalions or companies for assault.

The promise of receiving better and more abundant food than that given
to the other troops (so important is the question of food to the German
soldier, who has been on somewhat short rations since 1916) has been
sufficient to bring forward volunteers for these companies.

These special troops are exempted from work in the trenches, and are
brought up to the lines only when needed. On such occasions they are
scattered all over the attacking front for the purpose of encouraging
by their example the elements which are not so well organized.

The Germans, who, after the Russian revolution, were enabled to
withdraw the best elements from their divisions on their Eastern Front,
made, in June and July, 1917, a frequent use of their _Stosstruppen_ in
counter-attacks in Artois, and in desperate and daily attacks on the
Chemin des Dames, but the result was far from expectation.

The _Stosstruppen_, obliged, like the ordinary troops, to attack in too
serried ranks, offer a splendid target to artillery and machine-guns
and, nine times out of ten, their rush is stopped before they can
engage in a hand-to-hand fight.

[Illustration: La Bovelle

May 5, 1917--10.30 A.M.]

We wonder what the German divisions on the Russian Front will be able
to accomplish without their best and strongest elements when the
Russian Army rallies and re-enters the war in earnest.


=3. Mission and use of the infantry in a division.= We have stated
that a division includes three or four regiments. We will now dwell on
the disposition of a division comprising two brigades of two regiments
each. It seems certain that this is the type that will be adopted by
the American Army, which possesses a sufficient number of men for this
normal constitution of a division.

_Front of a division._ The front of a division in trench warfare is
very variable in extent. The occupation of strong intrenchments,
enabling the reserves to be sheltered from the enemy’s fire, allows
of the extension of the front, especially if the army remains on the
defensive.

As soon as a division takes the offensive, however, its front is
reduced to such proportions as will permit of energetic effort. The
front of a division in the open field has been fixed at 1800 to 2000
metres. The operations in 1914 showed that the fronts were always
longer than this and often twice as long and such will perhaps
continue to be the case in future if the war in the open is resumed;
but, so long as the war remains one of intrenchments, it will be
very dangerous not to limit the fronts, especially at the time of
an offensive. This is an acknowledged truth, and there is a growing
tendency, especially in the British Army, to shorten the front of
attack of a division.

DISPOSITIONS. The most logical mode of disposing the troops in a
division on the battlefield will always consist in the junction of the
two brigades side by side, and, in the brigades, the junction of the
regiments side by side.

The division, the brigade, the regiment, and even the battalion, have
each to constitute reserves either to ensure success or to guard
against possible failures in their offensive. In this warfare of
position, even more perhaps than in one of movement, the necessity of
always having troops near at hand, ready to repel counter-attacks, is
imperative, owing to the fact that every repulse is followed by the
enemy’s occupation of a part of the line of defence which would have to
be retaken later with great losses should the enemy be given time to
organize themselves therein.

[Illustration: North of La Bovelle

April 24, 1917--10 A.M.]

The disposition of the units in depth enables the Command, when the
lines are cleverly constructed and their intercommunications well
assured, to keep only a few men in the severely bombarded spots, and
to shelter the largest part of the troops where they cannot be injured.

The study of the last large operations, especially on the British
Front, shows that the experience and training gained by the British
troops in the field, and the cohesion of their artillery and infantry,
have compelled the Germans to abandon their method of distributing
their forces in 1916 and to adopt a quite different system of fighting.

In the battle of the Ypres-Menin road the Germans launched three
divisions on a very narrow front, with three battalions, one from each
division, on the first line.

Immediately behind each leading battalion a second was placed
to support it. The other two battalions of each regiment of
four battalion-formation, and the third battalion of the three
battalion-regiments, were held in reserve in depth to try and check the
English advance and to execute detailed counter-attacks.

Behind these divisions of attack, special troops, carefully selected,
composed a general reserve, waiting in very solid shelters where
they were protected from heavy-artillery bombardment. These reserves
were used when the first line divisions failed to check the enemy’s
advance, or when there was a chance of retaking lost ground by violent
counter-attacks.

The natural consequence of this new distribution of the German troops
is that to counteract it successfully very narrow fronts have to be
adopted. Forces strong enough to repel the enemy, and permit no time
for the supporting battalions to engage effectively, have to be placed
on the first line. The first lines are to be backed up by reserves
strong enough to oppose the enemy reserves without any loss of time.
A general reserve is to be kept in readiness in sufficient force to
hold the conquered positions against all counter-attacks which may be
launched by the general reserves of the Germans.

The last operations of October show that these dispositions are now in
force in all the armies.

DEFENSIVE. We have just explained the dispositions the Germans had to
adopt on the defensive, and we think that all parties will perforce be
led to adopt a somewhat similar distribution.

[Illustration: La Bovelle

May 5, 1917--10.30 A.M.]

The power of resistance of the trench-lines of the Allies being far
inferior to that of the German lines, the Allies must, to guard against
the danger of attack, take advantage of the superiority of their
artillery. They must dispose their forces in depth, in such a way as to
ensure the repulse of the enemy by a succession of assaults that will
stagger him and prevent him from re-forming.

It is impossible to give hard and fast rules for the distribution
of forces between the different lines of the divisions, regiments,
battalions, and companies. The distribution depends entirely on the
nature of the operations, and is left for each unit to carry out
in conformity with the orders received. When sufficiently detailed
instruction has been given to a unit in the course of its training,
these distributions are an easy matter to decide upon, provided the
officers of all ranks perform conscientiously the duties we have
indicated elsewhere.

ASSAULTING AND OCCUPATION TROOPS. Experience has suggested to the
Allies to divide their fighting troops into army corps for assault and
army corps for occupation.

Once the objectives are attained and strongly held, the assaulting
troops are replaced by the occupation troops that arrive fresh on the
ground. Their task, though one of defence, is often hard. They have to
remain a long time in the first lines, exposed, by reason of the new
German methods, to frequent and severe bombardments, and obliged to
repel numerous counter-attacks.

The generals commanding-in-chief are the exclusive judges of the part
the different army corps will have to play, but, in our opinion, there
is one principle which must never be ignored in war. In the army, as
well as in the battalion and in the company, it is the duty of the
Chief to select for action, irrespective of any rotation of service,
that element of the troops under his command which he deems the one
most likely to achieve the desired result.

What we have said concerning the use of the artillery, the armament
of the infantry, the distribution of the infantry in the division and
the trenches of attack, will enable us to give an exact idea of the
physiognomy of an offensive action and of its preparation.

OFFENSIVE ENGAGEMENTS. THEIR PREPARATION. The preparation of attacks in
a war of position is a long one. On account of the work it necessitates
it is very difficult to conceal these preparations on the front from
the opposing aviation, and also, alas! from the curiosity of the rear.

An attack can be determined upon only by order of the
General-in-Chief, who decides where and on what front it shall be made.
He gives his instructions to the General in command of an army group,
who, according to circumstances, employs one or several of his armies
for the operation. Each General commanding an army prepares an order
of operation for each of his army corps, and so on, until the precise
instructions reach the elements of the first line.

The preparation then commences. It consists in establishing on the
terrain under the protection of the batteries:

1st. The new lines of the infantry, and, if necessary, the
communications between these lines;

2d. The location of the artillery of all calibres;

3d. The organization of the posts of command;

4th. The bringing up of the munitions and material of all kinds;

5th. The construction, at the rear of the front of attack, of railroads
and ordinary roads in sufficient number, rather in excess of the
estimated needs than otherwise;

6th. The organization of the reserves of infantry.

7th. The preparation for the evacuation of the wounded, and the
installation of large field hospitals, as close as possible to the
lines;

8th. The organization of stations of evacuation;

9th. The organization of the parks;

10th. The organization of the centres of supply, etc.

This enumeration, from which we have omitted the aviation, by reason of
its special installations on appropriate grounds, gives a sufficient
idea of the labour required in preparing an offensive, which takes
generally several weeks to accomplish.

A few days before the attack, an effort is made to secure the mastery
of the air. Destruction fire is then directed against the opposing
trenches. The comparison of the different photographic plates handed
daily to the General Staffs enables the Command to watch the progress
of the destruction of the lines and positions of the enemy. When the
destruction is deemed thorough enough, the order is given to attack,
at given points, at a given hour of a certain day. The last operation
of the artillery, called “the rolling surprise fire,” consists in
subjecting numerous portions of the front to a series of terrific
and rapid bombardments, which leaves the enemy in doubt as to the
points against which the attacks of infantry are to be launched.
At the time appointed these attacks commence. The field artillery
covers its infantry by barrages as intense as possible. The first
assaulting waves, followed by those of the supporting troops, rush to
the objectives selected, drive off the enemy by all means at their
disposal, occupy and organize them. If necessary, the reserves come in,
either to help the assaulting troops, or to repulse the counter-attacks
of the enemy, if any occur.

[Illustration: Trench “Battemburg”

May 4, 1917--Noon]

It was decided some time ago that the troops must not, yielding to
their ardour, or the excitement of a too easily acquired success,
go beyond the objectives that have been assigned to them. A close
examination of the defensive dispositions of the Germans which we have
described reveals the wisdom of this precaution. It does not follow
that additional objectives cannot be taken on the same day, but in this
case the additional advance will be made by a fresh attack and the
effort will be distributed accordingly.

Documents found on Germans in Champagne, in August, furnish the
following details of an attack they had prepared north of the Souain
Hill. A similar attack had been rendered impossible by the action of
the French at Verdun, and by the destruction of the gas reservoirs by
the French artillery.

Three fresh divisions and fifteen companies of _stosstruppen_
(shock-troops, or special troops of assault) were to lead the attack
with light machine-guns, _minenwerfer_, signalmen, miners, sappers,
gasmen, grenadiers, stretcher-bearers, and artillery patrols. Twelve
“booty-squads” and twelve “destruction-squads” each composed of
an officer and thirty-two men were to follow the _stosstruppen_.
Arrangements had been made with a view to removing the captured guns.

They had prepared for a formidable discharge of a new gas by a
six-company regiment of sappers.

The gas attack was to be launched for a quarter of an hour. A
very strong artillery preparation was to follow, after which the
_stosstruppen_ were to rush forward.

The aviation was to play an important rôle, and the attack was to be
made with the aid of all the means of liaison known: dispatch-runners,
telephonists, optical signals, carrier-pigeons, luminous rockets, and
wireless telegraphy.

[Illustration: West of Ailles

May 4, 1917--Noon]

Orders had been given to bring back as many French gas-victims as
possible, with a view to studying the effects of the new product.

On the 20th of November, 1917, the third English army, by a successful
surprise attack, penetrated into the German lines to a great depth and
on a large front.

This operation, prepared in the greatest secrecy, was carried out
without the usual assistance of the artillery or barrages. The infantry
attacked under the protection of numerous tanks which destroyed the
wire entanglements and the most important obstacles.

We do not think that this method will henceforth become a rule.

Before launching this attack, the British Commander must have been
informed by his aviation, or by some other means, that the German Front
was lacking in artillery and infantry and he must very cleverly have
taken advantage of this momentary situation.

Must we conclude that the rules of preparation of attack, as stated
above, will not be applied hereafter? It is very doubtful, in view of
the fact that the Germans have prepared in France too many lines of
defence, one behind the other.

This English victory, however, shows that the High Command, whenever
in possession of information warranting the hope of success, will have
to combine regularly prepared attacks with surprise attacks on points
where the German effectives happen to be reduced.

The success of this operation on the Cambrai Front proves that, however
strong a position may be, however numerous its wire defences, it will
always be possible to take it when not protected by a sufficient force
of artillery and infantry.

DEFENSIVE ENGAGEMENTS. When the troops have to withstand an attack
on their lines, they must bear in mind the very sound principle of
war that a passive resistance can only end in defeat. On the first
lines all the elements necessary for as long a resistance as possible
will have to be accumulated. The infantry will then have occasion
to make a telling use of rifles, grenades, rifle machine-guns, and
machine-guns in as great a number as possible. The supporting troops
and the reserves must be ready to counter-attack the enemy without loss
of time, and throw him out of any trenches he may occupy temporarily.
We have often seen German attacks on advanced trenches repulsed in
the very moment of success by a simple bayonet charge made by the
troops of the first lines. To the field artillery, however, belongs
the most important rôle in repulsing the attacks of the enemy, and
the “communiqués” of all the Allies show that eight out of every ten
attacks are repulsed by barrage fire. When the aviators can report in
time exactly where the enemy troops are being massed for attack, the
trench artillery can work great havoc in the ranks of those usually
compact formations.

[Illustration: View taken about 10 A.M. during the attack of May 5,
1917]

PROLONGED ENGAGEMENTS. What we have just said refers to attacks made
from regularly organized lines which have not been entirely destroyed
by shell-fire.

On a ground where fighting has been proceeding continuously, the
trenches are entirely destroyed, and the men and machine-guns
belonging to the first-line troops remain with no other shelter than
shell-craters, which are, as far as possible, connected together during
the night by shallow trenches, provided this work is not prevented by
continuous shell-fire. The communication trenches with the rear do not
exist any more; and connections can only be maintained with the utmost
difficulty; by what means, we will later explain.

In order to resume the attack under such conditions, it will be
necessary to choose the exact moment when the enemy is supposed to be
demoralized by the artillery, and to rush the troops forward. In nearly
every case, the assistance of fresh troops or of troops that have
suffered little will be needed.

These field operations are difficult and require from both the chiefs
and the soldiers a resolute will to conquer, and a thorough knowledge
of war conditions.

During the last battles on the Somme, on the Aisne, and at Verdun,
advanced infantry fractions had to hold out for several days in
shell-craters, not connected with one another, and often filled with
water. The heavy enemy shell-fire rendered every move impossible and
stopped the arrival of all supplies. The adverse lines were often
merged into one another and from hole to hole grenade fighting was
kept up. It was nevertheless under such trying conditions that our
troops fought inch by inch to defend the French lines at Verdun, and
their heroic resistance enabled the Command to prepare new positions,
to redistribute the troops and to move them forward, after they had
finally thwarted the great German effort.

[Illustration: View taken about 10 A.M. during the attack of May 5,
1917]

POSTS OF COMMAND. In a division all the commanders of units from
the General of Division to the Major direct the fight from quarters
called Command Posts. These quarters, rendered as much as possible
proof to field artillery fire, must overlook the battlefield. They are
fitted with all the rapid means of communication, both telegraph and
telephone. The wires, although numerous and deeply buried seldom resist
the bombardment until the time of attack. As a last resource recourse
is had to signals, optical devices, carrier-pigeons, and messengers.
Apparatus for ground-telegraphy, which seems destined to come into
general use, has lately been employed, but we have not seen it in
operation.

As communications between the advanced lines and the rear have become
so very difficult during the preparation bombardment and the barrages,
which are often uninterruptedly kept up for several days, the western
armies have again had recourse to the carrier-pigeons, which are
furnished in large numbers by private societies, existing before the
war. Their co-operation is very useful and helps to save many human
lives. They are also sent out by airplanes whenever the use of wireless
telegraphy is not deemed expedient. They render great service in
keeping the front in communication with the rear, and are also of
priceless value for connecting the rear with the front.

SIGNALLING. The difficulty of communication between the rear and the
front during the bombardments will necessitate the increasing use
of infantry aircraft for the direction of operations. The aircraft,
connected by wireless with the various divisional headquarters, are
able to send information and in turn, to receive and transmit orders by
signal to the troops on the front.

These aircraft will also maintain a connection between the infantry and
the field artillery, which must be close and continuous if demoralizing
consequences, such as have only too frequently occurred in all camps,
are to be averted.

After the Anglo-German battles in Artois, the German prisoners,
respectively of the infantry and the artillery, had to be separated,
so great was the feeling between them. The infantrymen claimed they
had not had sufficient protection, and wanted to “take it out” of the
gunners.

So as to avoid confusion during infantry attacks, the guiding aircraft
ordinarily send up but one sort of rocket-signal, indicating to the
artillery either a lengthening or a shortening of the range by one
hundred metres.

[Illustration: View taken about 10 A.M. during the attack of May 5,
1917]

BATTALIONS OF THREE COMPANIES. At the same time that the effectives
of certain divisions were reduced, the battalions were returned to a
three-company formation.

A company of infantry is in principle composed of two hundred and
fifty men, a quota which is however purely theoretical, as this number
becomes rapidly reduced by various causes, such as illness, loss in
battle, etc.

FRAMEWORK OF THE ARMY. The ranks of the officers and non-commissioned
officers of the French Army have been renewed several times since the
beginning of the war. Many captains in 1917 were mere privates in
1914 and most of them are very young. They are, generally, excellent
officers, and it is to be regretted that those who have proved their
worth are not even more rapidly promoted.

The spirit of routine that prevails in an army officered by soldiers of
regular professional training is often responsible for the promotion to
high command of men too old for the effective direction of a long and
exhausting war like the present one.

There is no reason to think that the American people, any more than
the British and the French, will meet with serious difficulties
in recruiting and quickly training a strong staff of officers of
all ranks. They will also, like the Allies, find no insuperable
difficulties in filling the gaps which the enemy’s fire will make among
them.


=4. A word about cavalry.= If in this treatise we have not devoted a
chapter to the use of cavalry it is because, since September, 1914,
cavalry has had but few opportunities to operate as such.

The cavalry has been generally used in the present trench warfare in
the same manner as the infantry. It has been reduced in number; that of
the army corps has been suppressed, and only two squadrons have been
allotted to each division.

Some regiments of cuirassiers have been dismounted, for want of proper
horses.

But we think that, notwithstanding the small part the cavalry has taken
in the war during the last thirty months, its opportunity is bound to
come.

Some cavalry corps, comprising several divisions, have been retained,
and during the offensives they are held in readiness to move to the
front in case the enemy lines should be broken.

Cavalry squadrons rendered good services to the British and French
during the pursuit in March, 1917.

The Germans will perhaps not always be able to protect their retreats
by the desert-like devastation of thirty or forty kilometres of
country. Their weak point will be found some day or other, and on that
day the cavalry will resume its importance.

The difficulty in feeding and obtaining horses seems to have compelled
the Germans to reduce their cavalry forces considerably.




CHAPTER VII

FORBIDDEN WEAPONS

  1. Asphyxiating gases.

  2. Tear-producing gases.

  3. “Gaz-vésicant.”

  4. Liquid fire.


=1. Asphyxiating gases.= During the present war Germany has ransacked
the arcana of science for the means of destroying her enemies. Those
to which she resorted had been forbidden and condemned as belonging to
barbarous ages by all the conventions to which she had been a party,
and by all the agreements that she had signed.

Asphyxiating gases were used for the first time against the British
troops on the Yser. The corrosive vapours of chlorine are fatal to all
who have been sufficiently exposed to them, and when first directed
against an unprepared and unsuspecting enemy, their effects were
terrible.

Fortunately the use of these gases is possible only when the wind
is favourable and the weather dry; and as the coincidence of these
conditions is exceptional, especially in the north of France, the
Allies had time to invent protective masks and distribute them to their
troops.

The models adopted can be slipped on easily and quickly even in the
dark and are effective for several hours. Every soldier is provided
with one.

At the start, when gas-offensives were still in the experimental stage,
the German attacks were limited to single discharges, which were more
or less rapidly dissipated by the wind and were quite harmless to
adversaries equipped with good masks.

But shortly afterward, when their weapons were turned against them, and
their trenches were “gassed” by the Allies, and the Germans discovered
by experience that a mask causes great fatigue and even exhaustion if
its use is greatly prolonged (since it interferes so much with the
breathing), they altered their method of procedure and began to take
advantage of favourable winds to launch successive waves of gas, in
order to wear their enemies out by keeping them in their masks as long
as possible.

Next, as the approach of the whitish gas-cloud was easily visible and
was always promptly signalled by the lookouts, the German scientists,
in an effort to catch their adversaries unprepared, modified their
original formulas and produced colourless gases, which are more
difficult but by no means impossible to detect.


=2. Tear-producing gases.= The next step was to find some means of
nullifying as much as possible the protection of respiratory apparatus,
so the _good_ Germans invented the tear-producing gases which, in spite
of the special glasses that have been added to the masks, rapidly
interfere with vision and place the victim _hors de combat_.

The Allies were forced, in self-defence, to resort to similar means.


=3. “Gaz-vésicant.”= A new gas invented also by the Germans has made
its apparition on the Western Front. It is known in France under
the name of _gaz-vésicant_; it acts after a few hours only; it is
colourless and inodorous; it destroys all the tissues as thoroughly as
they would be under the action of sulphuric acid.

We have mentioned the preponderant use of asphyxiating shells in
neutralization fire. All our armies are now provided with a variety of
gas-generating apparatus, some of which have given excellent results
as regards accuracy and rapidity of discharge.

There is another reason why the Germans should be unable to
congratulate themselves on this invention. Westerly and north-westerly
winds are more frequent in France than easterly winds, so that gas
attacks can be made oftener by the Allies than by their enemies.


=4. Liquid fire (_flammenwerfer_).= When neither guns nor gases
fulfilled their expectations and they saw that the “furor Teutonica”
embodied in the mass-attacks of the best soldiers of the Kaiser was
powerless to break through the Franco-British lines, the Germans
resorted to the use of liquid fire.

In favourable weather before the attacks are launched, men in heavy
bullet-proof steel breastplates are sent forward, carrying on their
backs reservoirs very similar to those used on farms to sprinkle
sulphate on the crops. Through nozzles connected with these reservoirs
they throw by the force of compressed air streams of burning liquid to
a distance of fifty to sixty yards. The dense clouds of black smoke
produced by the liquid fire mask its bearers from the sight of the
enemy.

Liquid fire, especially at the beginning, when the Allies were
unprepared for this mode of attack, rendered good service to the
Germans by enabling them to take some advanced trenches at small cost
to themselves.

The present results are less brilliant. Grenades have done the work
against the mail-clad bearers of _flammenwerfer_ that rifles or
machine-guns could not. When a bearer falls, the masterless nozzle does
not always continue to spit its flames in the direction of the enemy,
but is often turned against the other bearers, and even against the
very troops whose advance it is intended to protect, thus spreading
great disorder in their ranks.

Recently, in order to compensate for the decreasing morale of
their troops the Germans have resorted more and more to the use of
_flammenwerfer_.

The Allies have in their turn adopted similar apparatus and the Germans
have more than once had the opportunity to realize that it is as useful
in the defensive as in the offensive.

Gas apparatus and _flammenwerfer_ should be as portable and as handy as
possible.

They should never be operated by other than specially trained troops,
fully instructed and thoroughly skilled.

In France detachments of sappers or miners are entrusted with these
devices.




CHAPTER VIII

CONCLUSION


We have endeavoured to present, without entering into the technical
details which are being taught by the officers composing the various
Allied missions, a general sketch of the conditions and principal
factors of modern warfare that will be sufficient to give an idea of a
modern army and its operation in the field.

It is hoped that our explanations will aid in reading between the lines
of the “communiqués,” in comprehending the plan and the importance of
individual engagements and finally in enabling those who have relatives
at the Front to follow them at their posts of duty and to fully realize
the importance of the parts assigned to them.

Before concluding, we should like to be granted the privilege of
expressing our personal opinion concerning the methods calculated to
hasten the instruction of the new armies of the United States.

Everyone agrees on the necessity of proceeding rapidly and effectively.

The defection of Russia on the Eastern Front and the recent very
serious reverses of the Italians, of which the Germans have not failed
to take prompt advantage, have rendered more difficult the efforts of
the Allied Armies on the Western Front.

The instruction of the American units can be terminated in France,
first in camps and afterwards in quiet sectors, until the American High
Command considers that the moment has come to throw its forces into the
thick of the fight.

Notwithstanding the immense resources of the United States, the
difficulties of transportation will doubtless be such as to force the
military authorities to hold a certain number of divisions in the
instruction camps in America.

The instruction of these troops ought, we think, to be as thorough as
possible.

The Allied countries have delegated to the United States distinguished
officers who have participated in the war and who know all its
difficulties. We should wish them to proceed, if only on a short front,
with an exact reproduction of the shell-torn fields over which the
American troops are destined to manœuvre in Europe. The small units
that could be successively and frequently trained on these prepared
fields would thereby have less time to spend in the instruction camps
in France and could more promptly be sent to the Front.

In the vast territories of the United States, ground adapted to this
purpose would not be difficult to find, and the plan would afford
opportunity to give the last divisions to embark complete instruction
in all matters of detail, and a perfect knowledge of all the component
elements of an army, from those of a company to those of a division.

Let us insist on the fact that, in this war, the art of rapid
excavation and intrenchment is one of the chief things to be learnt by
the troops, as special formations cannot be detailed for this work, and
every soldier has to carry an intrenching tool and must know how to use
it.

It will therefore be necessary for the units to practise intrenchment
on a large scale, and finally to perfect their instruction by exercise
over shell-torn ground similar to that of the Front.

We would suggest, in order to familiarize the troops with the actual
mode of destroying defensive works, practice with such obsolete
artillery as is not fitted for use at the Front. It is of paramount
importance also to accustom the men as rapidly as possible to the sight
and sound of gun-fire. We would suggest that the final exercises of
assault be accompanied by curtain fires made, to avoid all risks of
accident, at about three hundred metres in advance of the first lines.

We can add that the mode of instruction we advocate here would be as
beneficial to the Chiefs as to the men. Thus only will they fully
realize beforehand the difficulties they will meet when facing the one
factor which it is impossible to include in any course of training--the
Enemy; an enemy that, to the end, will be skilled and formidable.

_12°. Illustrated. $1.50 (By mail, $1.65)_


In the amazingly vivid and simple way that has made =_Over the Top_=
the most widely read and talked of book in America, and the most
successful war book in all history, Empey tells the new soldiers

        _What they want to know_
        _What they ought to know_
        _What they’ll have to know_

and what their parents, sweethearts, wives, and all Americans, will
want to know, and can do to help.

A practical book by an American who has been through it all.

The chapters headed “Smokes” and “Thank God the Stretcher Bearers” will
stand among the war classics.

Here is advice, here are suggestions, overlooked in other books, that
will safeguard our boys in France.

  _IT IS THE REAL STUFF_

  _OVER THE TOP_

  BY AN AMERICAN SOLDIER WHO _WENT_

  _ARTHUR GUY EMPEY_
  MACHINE GUNNER, SERVING IN FRANCE


  _AUTHOR OF_
  “_FIRST CALL_”


For a year and a half, until he fell wounded in No Man’s Land, this
American soldier saw more actual fighting and real warfare than any war
correspondent who has written about the war. His experiences are grim,
but they are thrilling and lightened by a touch of humor as original as
the Soldiers Three. And they are _true_.

Transcriber’s Notes


Simple typographical errors were corrected. Punctuation, hyphenation,
and spelling were made consistent when a predominant preference was
found in the original book; otherwise they were not changed.

The apparent hierarchy in the Table of Contents (capitalization and
what is included in that Table) is not the same as the apparent
hierarchy of the rest of the book (centered headings, boldface
sections, and small-cap sub-sections). This discrepancy has been
retained in this eBook.

Illustrations in this eBook have been positioned between paragraphs
and outside quotations. In versions of this eBook that support
hyperlinks, the page references in the List of Illustrations lead to
the corresponding illustrations.

The index was not checked for proper alphabetization or correct page
references.
