TACTICAL USE OF THE THREE ARMS.


Every complete military force consists of three arms,--INFANTRY,
ARTILLERY, and CAVALRY.

In battle, these three arms are united; and, other things being equal,
that commander will prove victorious who is best acquainted with their
combined use in the field.

In order thoroughly to understand the proper use of the three arms
combined, we must obviously begin by learning the proper use of each of
them separately.

Hence the importance of the subject of the present treatise. In
discussing it, we shall commence with the




TACTICAL USE OF INFANTRY.


The subject will be considered under the following heads:--

   I.--ITS ATTACK, GENERALLY.
  II.--FORMATIONS FOR ATTACK.
 III.--THE ATTACK, HOW MADE.
  IV.--BAYONET CHARGES.
   V.--DEFENCE AGAINST INFANTRY.
  VI.--DEFENCE AGAINST ARTILLERY.
 VII.--DEFENCE AGAINST CAVALRY.
VIII.--SQUARES.
  IX.--SKIRMISHERS.


I.--Its Attack, generally.

Infantry attacks with its fire, or with the bayonet. Which of these is
the more effective?

1. The _object_ of an attack is to destroy or capture the hostile force,
or, at least, to drive it from the field.

Capturing the enemy, or driving him from the field, cannot usually be
effected by merely firing upon him.

True, a mere fire at a distance may finally destroy him. But an
insuperable objection to this mode of attack is, that while we are
killing or disabling his men, he is killing or disabling as many of our
own.

2. If we fire from _behind cover_, our loss may be comparatively small.
But, in that case, the enemy will never remain for any length of time
exposed to our fire. He will either attack and rout us from our cover,
or retire. And even if he did neither, his actual and complete
destruction, capture, or rout, would still require an attack with the
bayonet.

3. It follows that the proper mode of attack by infantry on infantry is
with the _bayonet_.

The Russian Suwarrow's victories and reputation were won chiefly by his
fierce bayonet attacks, which often effected great results, in spite of
his ignorance of the art of war.

4. But there are _exceptional cases_ where infantry may properly use
only its fire; as--

(1.) When acting as a support to artillery, it should rarely, if ever,
leave its position to use the bayonet; thereby endangering the safety of
the guns which it is its first duty to guard. Its function, in this
case, being purely defensive, it should act by its fire alone.

(2.) Against a line of skirmishers deployed, a well-directed fire will
usually be sufficiently effective.

(3.) In mountain warfare, its only practicable mode of attack will
sometimes be by its fire.

5. When both sides are _equally exposed_, the actual attack with the
bayonet should not be preceded by a distant musketry fire; for, as in
that case, our loss will generally be equal to the enemy's, this fire
will give us no superiority in the charge, and the loss we have
sustained will be therefore entirely thrown away.

6. Nevertheless, our actual attack should be _prepared_, when possible,
by the infliction of such a loss on the enemy as will make him inferior
to us at the decisive moment. In war, the object is not to test the
comparative courage of the combatants, but to beat the enemy. We must
never, therefore, when it can be avoided, fight him on equal terms; and
so, never close with him without such a superiority in numbers,
position, or spirit, as will make the chances decidedly in our favor.
If, without exposing ourselves to much loss, we can inflict a
considerable loss upon him, we shall render him inferior to us, both by
the number of his men we have disabled, and by the demoralization
thereby caused in his ranks.

7. This preparatory loss can be most effectually inflicted by the _fire
of artillery_; as, from its great superiority of range, it can suffer
but little, meanwhile, from the enemy's infantry fire. Our attacking
infantry are thus enabled to keep out of the range of the fire of the
infantry they are to attack, till the moment of advancing to close.

8. When we have no artillery disposable for the purpose, the preparatory
effect may be produced by a _well-sustained fire of infantry_, provided
it can find a sheltered position to deliver it from; or, by the fire of
a heavy line of skirmishers.

9. If we can make the infantry we wish to attack _engage in a prolonged
fire_, this will exhaust them, and thus render them inferior to us in
strength and in spirit, even if we inflict on them but little loss. But
as our attacking infantry should, in the mean time, be kept fresh, the
preparatory fire, in such case, should not devolve on the troops that
are to close with the enemy.

10. One cause of the _indecisiveness of the results_ obtained in many of
the battles of the late war, as compared with the great loss of life on
both sides, has been, that the opposing battalions were too often kept
firing at each other at a distance, both sustaining nearly equal loss,
until the ranks were so weakened as to disable either party from making
a vigorous and decisive charge. Or else, charges were made on the
enemy's battalions before they had been shattered by artillery; so that
the attacking troops were easily repulsed, sometimes with great
slaughter.


II.--Formations for Attack.

1. Infantry may advance to attack in either of _three ways_: in column;
in line, marching by the front; and by the flank; that is, in line, but
faced to a flank.

2. Of these three formations, the last is undoubtedly the _worst
possible_; for--

(1.) On arriving at the enemy, the troops are not concentrated at the
point where the struggle is to be. As they must come up successively,
they will be crushed in detail by superior numbers.

(2.) Advancing in such a formation, they would be exposed to a
destructive raking fire from the enemy's guns; especially since the
adoption of the new flank march by fours, which gives to rifled
artillery a tolerable mark.

3. The question is, then, between an attack in column and an attack in
line. _Which is the better_ of the two?

The decisive effect of infantry is produced by a rush on the enemy with
the bayonet. The chief elements of success in this attack at close
quarters are, the physical momentum of the charge, and the powerful
moral effect caused by the swift approach of a compact and orderly
hostile mass. A charge in line does not admit of both these elements.
The advance of a line of one or more battalions, to be united and
orderly, cannot be rapid, and thus has no impetus. Such a line,
advancing swiftly, especially over uneven ground, would soon become so
broken and disunited as to destroy, in a great measure, the effect, both
moral and physical, of its charge, and, at the same time, to deprive the
attacking troops of that confidence which is inspired by the
consciousness of moving together in one compact, formidable mass, in
which every soldier feels himself fortified by the support of his
comrades.

4. On the other hand, _a column_ can move rapidly without losing its
compactness and order.

In attacking the enemy's line, a close column concentrates successively,
but rapidly, a force superior to the enemy at the decisive point, and
can hardly fail to pierce the line attacked, if it arrive with its
momentum unchecked.

In a close column, there is a real force created by the pressure of the
mass behind on the leading subdivision, pushing it on the enemy, and
preventing it from drawing back or stopping; thus imparting to it
somewhat of the actual physical momentum of a mechanical engine.

A close column shelters raw troops, and carries them irresistibly along
with it.

A close column, in case of need, can rapidly extend its front by
deploying.

It can promptly make itself impenetrable to cavalry.

Finally, in a column, the officers being seen by the men, the benefit of
their example is not lost.

The close column would, therefore, seem to be the best formation for
attack.

5. Movements in line requiring that high degree of perfection in drill
which can rarely be attained by any but regular troops, they were
accordingly abandoned by the raw and undisciplined masses of French
soldiers that so successfully defended the French Republic from invasion
against the veteran armies of Europe; some of which were led by generals
who had served under Frederick the Great. Conscious of their military
inferiority to the enemy, they instinctively clustered together in
close and heavy columns; then rushed down on the enemy's line with the
force of an avalanche, often carrying every thing before them. Thus was
inaugurated that system of attack in _deep and solid columns_, which was
afterwards so successfully used by Napoleon.

6. Close columns have two defects. One is, that they are _oppressive and
exhausting_ to the men, especially in hot weather.

But this is not a very serious objection; for they are, or should be,
formed only when about to be used, and then their work is generally soon
over.

7. The other defect, however, is of so grave a nature as, in the opinion
of some, to more than outweigh their advantages; and this is, the
_terribly destructive effect_ upon them of the enemy's artillery fire,
or of that of his sharpshooters; for the solid mass is an easy target,
into which every shot is sure to penetrate. Many of the missiles which
would fly over an advancing line, are sure to fall, somewhere or other,
in a deep column.

This destructive effect was strikingly illustrated in Macdonald's charge
on the Allied centre at Wagram. The eleven thousand men (some accounts
say fifteen thousand) composing that famous column, advanced under the
fire of one hundred and eighty hostile guns. After being driven back
twice, they succeeded, in a third attack, in breaking the enemy's
centre. But of the entire column, only eleven hundred men, it is said,
were left standing.

8. The recent improvements in fire-arms must render the fire on a close
column of infantry, both by artillery and sharpshooters, still more
destructive than it was before. But this sacrifice of life can be
prevented, to a great extent, by using the columns at a proper time and
in a proper manner. They should, like storming parties (which they
really are), never be launched against the enemy's line till the fire by
which they would suffer has been _quite or nearly silenced_ by our
batteries. Sometimes this may be impracticable; but this precaution has
often been neglected when it was perfectly feasible, thus causing a
great and useless slaughter.

9. But destructive as may be artillery fire on close columns, on troops
advancing in line grape and canister _begin to be equally so_ on their
arriving within four hundred yards of the enemy's batteries; and are
certainly quite as destructive, and more so, at the distance of two
hundred yards. So that, within this distance, at least, the superiority
of lines over columns ceases; and, probably, much sooner.

10. The _desideratum_ is to preserve the advantages of the column, while
saving the attacking troops from the almost total destruction which
would now seem to threaten them, when marching in such a formation, from
the new rifled artillery, which is said to fire with accuracy at two
thousand yards, and from the new infantry rifles, said to be reliable,
in the hands of sharpshooters, at five hundred yards.

11. Perhaps this object might be attained by the advance of the
attacking troops in line, but _in loose order_, and at double quick, to
about two hundred paces from the enemy, a halt, a prompt alignment on
the colors, a rapid ployment into close column doubled on the centre,
followed by a swift and resolute charge with the bayonet.

This method, while giving the rapid clearing of the intervening ground,
to within two hundred paces of the enemy, and afterwards the impetus,
and other advantages of the column, would, at the same time, afford that
comparative immunity from a destructive fire which is the chief
advantage of an advance in line.

To guard against the danger, in the use of this method, of the troops
stopping to fire, instead of ploying into a column of attack, they
should commence their advance with pieces unloaded. Their boxes might
even be previously emptied of their ammunition. Why should not a battle,
as well as an assault on a fortress, have its "forlorn hope?"

12. This mode of attack would be open, it is true, to _two
objections_:--

First. It would require for its successful execution under fire great
coolness, and much previous instruction in the manoeuvre, to enable
the troops to perform it promptly and accurately.

Secondly. In presence of a bold and active enemy, it would expose the
attacking troops to the danger of being charged and routed while
manoeuvring.

13. In the late War of the Rebellion, in lieu of close columns, attacks
have been sometimes made in _several lines_, following each other at
distances of three hundred paces or more. Although these attacks have
sometimes succeeded, they are objectionable in principle; for each line
is in danger of being repulsed successively, before the arrival of the
one in its rear; and there is wanting that great superiority of force at
the decisive point which is the most important element of success in a
battle.

Such formations are essentially defensive in their nature, and not
suitable for attack. A line in position, against which the enemy is
advancing, is strong in its fire, which will usually preserve it from
absolute defeat till a second line, posted at one hundred and fifty, or
even three hundred paces in its rear, has had time to come up in
support. But even these distances Napoleon's experience appears to have
taught him to be much too great; for in his last battle, at Waterloo, he
posted his second line, both infantry and cavalry, at only sixty paces
behind the first; thus sacrificing, to a great extent, the advantage of
keeping the second line out of fire, in order to secure the more
important one of concentration of force. But this was only his formation
for defence; for, in the same battle, his formations for attack were
always in close columns.

14. Our present Infantry Tactics have adopted two new expedients to
accelerate the advance of battalions, and diminish the loss to which
columns of attack are liable--Division Columns and Advancing by the
Flank of Subdivisions.

As _Division Columns_ break the battalion line into several columns,
each of two or three subdivisions deep, as a substitute for a single
column four or five subdivisions deep, they undoubtedly diminish the
loss from the enemy's artillery fire in corresponding proportion. But in
compensation for this partial advantage, they have three defects:--

(1.) In moving rapidly for any distance, especially over broken or
obstructed ground, both the alignment and the proper intervals between
the columns will usually be lost; thus causing, in the deployment, a
dangerous loss of time in re-establishing the alignment and the correct
intervals.

(2.) In advancing in line of division columns, there is no means of
forming square, except by passing through an intermediate formation.

(3.) The intervals between the columns are so many gaps, through which
cavalry could easily penetrate, and take the columns in rear.

The line of division columns appears to have been first suggested by
Marshal Marmont, who was a good artillery commander, but not
necessarily, for that reason, a weighty authority on a point of
Infantry Tactics.

15. The manoeuvre of _Advancing by the Flank of Subdivisions_ is
obnoxious to all the objections just pointed out in regard to Division
Columns. On being threatened by cavalry, though the troops would have no
intermediate formation to pass through to prepare for forming square,
they would have to face into column and close to half distance, which
there would often not be time to do.

In addition to this, the flank march being habitually by fours, the
subdivisions would offer a tolerable mark for the enemy's artillery, and
thus be exposed to a destructive enfilade.

And in forming into line, where the leading guides have not accurately
preserved both their alignment and their intervals, which must be the
usual case in the field, there must be more or less delay and confusion,
of which a prompt and active enemy would not fail to take fatal
advantage.

The mode prescribed by the Tactics (Par. 150, School of the Battalion),
for executing the manoeuvre of forming line while advancing by
subdivision flanks, seems also to call for remark; it being "by company
(or division) into line." In other words, each individual soldier
brings a shoulder forward, breaks off from his comrades, and hurries up,
not on a line with them, but detached from them, and moving
independently, to find his proper place. This destroys for the time
being, and at a critical moment, the unity of the subdivisions, and so
impairs the confidence soldiers derive from realizing that they form
part of a compact mass. In thus executing this manoeuvre under fire,
and near the enemy, there is danger of the men becoming confused and
bewildered. For this reason, a better method of forming line would seem
to be to re-form the column by a simple facing, and then to _wheel_ into
line by subdivisions.

16. The worst possible _order of marching_ in battle, for any
considerable number of men, as a battalion, for instance, is by the
flank. Such a line, advancing in what is really a column of fours, would
be rolled up and crushed, on the enemy's attacking its head; and would,
meanwhile, be exposed to enfilade. Marching _to_ a flank, it would be
running the gauntlet of the enemy's batteries and musketry fire. In
forming into line in either case, much time would be lost; as in flank
marching in the field, especially when the ground is ragged or
obstructed, distances cannot be preserved.

It may be here remarked, that marching to a flank in column also,
whether by division, company, or platoon, is highly objectionable, as it
constantly exposes the column to an enfilading fire, as well as to be
suddenly charged in flank by cavalry.


III.--The Attack, how made.

1. The speed of a column of attack must _never be checked_ for a moment,
to enable it to reply to the enemy's fire. The fire of the column will
be ineffective, for it will be the fire of excited men, and very limited
in extent, as it can proceed from the leading division only; and the
fire once begun, it will be hard to stop it. If, in order to fire, we
halt the column, re-forming it under the excitement of the fire will be
very difficult; and the enemy's least forward movement may then cause a
rout.

At Maida, in Calabria, in 1806, the French columns attacked the English
under General Stuart. When within thirty paces, the English gave them a
volley. The French, stunned, as it were, began, at once, to deploy. The
English fired again, and the French retreated.

At Waterloo, in the last grand attack by the French, the advance column
of the Imperial Guard was decisively repulsed by the British Guards.
These had been lying on the ground behind the crest of the slope until
the French appeared, when they suddenly rose up and poured in a
murderous volley at short range. Instead of instantly charging with the
bayonet, the French hesitated, then began to deploy. The British charged
at once, and drove them down the hill.

2. This dangerous halt and deployment is apt also to occur when the
column finds _sheltering objects by the way_. Therefore, hurry by these,
and hasten the step.

3. It will also tend to prevent such an untoward accident, if we furnish
the columns of attack, where several are employed, with _skirmishers_ in
their intervals, as well as on their outer flanks, to draw the enemy's
fire. Otherwise, the column fired into will be apt, in order to return
the fire, to halt instinctively and deploy into line, which breaks up
the attack.

4. From this it appears that the limited fire of a column of attack is,
in fact, _no defect_, the highest offensive power of infantry being in
the bayonet. Fire, in the attack, is generally ineffective, and
sometimes injurious. It should rarely be used till the enemy has turned
his back.

5. As to attacking _cavalry_:

Infantry may advance in line and attack cavalry safely, provided its
flanks are protected. Before a long line of infantry, cavalry must
retreat, or be destroyed by its fire. In the Austrian service it is said
to be a received maxim, that horses will not stand before the steady
approach of a mass of infantry, with bayonets at the charge, but will
always retire before the infantry closes on them.

6. So, infantry _in column_, either closed in mass, or at half distance,
may attack cavalry successfully; taking care to be ready to form square,
or "column against cavalry," at the first symptom of their preparing to
charge.

7. As to attacking _artillery_:

Before charging, the infantry sometimes first seeks the shelter of
ground, using its sharpshooters to annoy it, and, if possible, to
silence its fire.

Or, when circumstances are favorable, as when it can get a position near
its flank, it attacks it vigorously, at once, with fire and bayonet.

But when infantry has to advance to the attack of a battery in front, it
should never be in any compact formation, but always deployed as
skirmishers. Otherwise, it would usually meet with a bloody repulse;
especially where any considerable space of ground is to be cleared.

At the battle of Malvern Hill, the rebel General Magruder's division was
sent, either in column or in line, to charge a powerful Union battery
just beyond an open field a mile and three-quarters in length. The
rebels rushed into the field at a full run, but encountered a murderous
fire from the guns they were sent to attack, which mowed them down by
hundreds. By the time they had cleared two-thirds of the ground, the
carnage was so dreadful as to drive them back to the woods from which
they had started. Twice more they were sent forward in the same manner,
but with the same result; when the undertaking was abandoned.

8. In attacking a battery, we may often secure its capture by a volley
_aimed at the horses_; the effect of which may prevent the enemy from
carrying it off. But this should be avoided when there is a good
prospect of capturing the battery without disabling the horses; since
then, if we succeed, we shall be able to immediately use the battery
against the enemy ourselves.

9. In the French Revolution, the Chouans of La Vendée attacked the
Republican batteries in _several single files_, of one or two hundred
men each, at intervals of fifty paces. Such a formation protects the
attacking columns, to a great extent, from the enemy's fire, but exposes
them to destruction by a charge from the battery supports. In the
absence of these, it would often be very advantageous; since, by proper
drilling, these columns in one rank could be made, on arriving near the
enemy, to rapidly double in two or four ranks, without halting, and
then, by filing to a flank and facing, to advance by the front in a
compact line.

The same formation would be useful for troops advancing to assault an
intrenchment; but, as in the case of a battery, subject to the risk of
being destroyed by a sudden sortie from the work.

10. Artillery is never without _supports_. One part of the infantry,
therefore, deployed as skirmishers, should attack the guns, circling
round them, and opening fire on the men and horses; while the other part
attacks the support in flank. On getting sufficiently near, the
assailants should try to draw the fire of the guns, and then rush on
them before they have time to reload.

If a battery gets into confusion, or there is any delay in unlimbering
or limbering up, then is the most favorable time to capture it by a
vigorous charge with the bayonet.


IV.--Bayonet Charges.

1. When made resolutely, and _without slackening the gait_, bayonet
charges have succeeded in nine cases out of ten.

2. The bayonet is usually more effective than _grape_, _canister_, or
_bullets_.

At the battle of Leipsic, in 1813, Kleist's Prussian division was sent
to carry the position of Probstheyda. For this purpose it was necessary
to advance up a long slope, the crest of which was occupied by Drouot's
artillery. The French allowed the Prussians to approach to within a
short distance, and then poured into them a most destructive shower of
grape, which drove them back for a moment in confusion. But they
immediately rallied, and rushed desperately on again. Marshal Victor
then charged them with the bayonet, and completely repulsed them.

Afterwards, having been re-enforced by Wittgenstein's Russian division,
they again advanced, under a constant shower of grape from Drouot. They,
nevertheless, kept advancing; and, in spite of the great loss they
suffered, were about carrying the position, when the French again
charged with the bayonet, forcing them down to the very foot of the
declivity; where, being once more covered with grape, their repulse was
complete and final.

So, at the battle of Mill Springs, in January, 1862, after the
combatants had been exchanging musketry fires for several hours without
any decisive result, the rebels' left was vigorously charged by the
Ninth Ohio with the bayonet. This charge broke the enemy's flank. His
whole line gave way in confusion, and the battle was won.

So, at Malvern Hill, in 1862, in several instances, columns of rebels
whom a storm of canister and shell had failed to repulse, were driven
back and routed by a dash with the bayonet, after a volley poured in at
a few yards from the muzzles of the guns.

So, at the battle of Seven Pines, according to General Heintzelman's
report, whenever our troops used the bayonet, their loss was
comparatively light, and the enemy was driven back, suffering heavily.

3. The bayonet charge, when made from any considerable distance, should
be _in column_; the only formation in which order can be combined with
sufficient speed. But, at a short distance, a bayonet charge by a line,
instantly after firing a volley to repel an attack, will be very
effective, and usually successful.

4. In ordinary cases, the charge should be _prepared_ by first
shattering the hostile masses, or, at least, wearying and demoralizing
them by artillery, or by skirmishers' fire.

5. The more _vigorous and resolute_ the charge, the greater the chance
of success. The enemy never retires before a moderate advance.

6. Where the enemy is _forced into a defile_, a charge with the bayonet,
preceded by a few rounds of grape, will complete his destruction.

7. When the enemy is _behind cover_, the best way to drive him from it
is with the bayonet. This will cause less loss of life than to attempt
to return his fire. But, in such case, the charge should be prepared,
when possible, by a few shells, or rounds of canister.

8. Shots up or down a declivity usually miss. A _height_ should,
therefore, be carried with the bayonet, without firing.

The moral effect, moreover, of a steady charge of infantry up a hill,
without stopping to fire, is very great; and such a charge is usually
successful. Prince Czartoryski, Alexander's most experienced general at
Austerlitz, admitted that he lost all confidence in the result on seeing
the French infantry ascending the plateau of Pratzen, the key to the
Allies' position, with a firm and decided step, without once stopping to
fire.

So, at Chattanooga, in November, 1863, Thomas's troops carried the
height of Missionary Ridge by a similar steady and determined ascent, in
spite of the volleys of grape and canister from nearly thirty pieces of
artillery, and of musketry from the rebels' rifle-pits at the summit.
General Grant attributed the small number of casualties our troops
sustained in the attack to the rebels' surprise at its audacity, causing
"confusion and purposeless aiming of their pieces."


V.--Defence against Infantry.

1. The defence of infantry is by its fire, and therefore its proper
defensive formation is in _deployed lines_.

2. Avoid a _premature commencement_ of the fire. Long firing exhausts
the men's energy, expends the ammunition, fouls the pieces, destroys the
soldier's confidence in his weapon, and emboldens the enemy.

3. So, a fire upon an enemy while _under cover_, as in a wood, would be
virtually thrown away. If his fire from such a position causes us any
loss, he had better be shelled, or driven away by skirmishers, according
to circumstances.

4. The practice of hostile regiments exchanging for a considerable time
a _musketry fire at a distance_, is highly objectionable, as it causes a
great sacrifice of life without corresponding results. Instead of
standing in line for ten minutes, receiving and returning fire at a
distance of three hundred yards, it would be much better to clear this
space at double quick in two or three minutes, and close with the enemy;
for, in returning his fire, we can do him no more harm than we receive,
while nothing decisive is accomplished. The case is, of course,
different where our own troops are behind cover, while the enemy's are
exposed.

5. But in _special cases_, as where we have to cover a flank movement of
our second line, or of the reserve, or to await a force coming to our
support, it may be necessary to keep up an incessant fusillade, without
regard to losses received.

6. Fire in action is of two kinds: the fire at will, and the fire by
volleys; the former kind being the rule, the latter the exception.
Although the fire at will is the one principally used, there are _very
strong objections_ to it.

(1.) The men load and fire as individuals, and generally with great
rapidity, and under more or less excitement, rarely stopping to take a
deliberate aim. The consequence is, that very few shots take effect, and
the fire is, for the greater part, wasted, as is shown by the
well-established fact that, in every engagement, for every man killed or
disabled, there have been from three to ten thousand musket or rifle
bullets fired.

(2.) Except on windy days, a cloud of smoke soon collects in front of a
line firing at will, hiding, more or less completely, the enemy from
view. The fire being then at random, it is, of course, unreliable.

(3.) The fire at will leads to a rapid and enormous consumption of
ammunition. To show how serious is this objection also, it is only
necessary to consider in how many instances victory has been turned into
defeat by the premature exhaustion, by one or more regiments, of their
ammunition.

(4.) As a necessary consequence of this rapid consumption of ammunition,
the pieces soon become fouled, and thus, to a great extent, useless.

(5.) Troops under a musketry fire at will, soon become accustomed to it,
and its incessant din produces on them a stunning effect, which deadens,
in no small degree, their sensibility to danger.

7. On the other hand, _volley firing_ has often been attended with
decisive results, especially when it has been reserved to the proper
moment, and delivered at short range. Instances of this have occurred in
almost every great battle we read of in history, as also in the late War
of the Rebellion. For example: at the battle of South Mountain,
Doubleday's brigade was engaged with a heavy force of rebels at some
thirty or forty paces in its front. Our men were behind a fence, firing
at will; but their fire made little or no impression on the enemy, who
attempted to charge at the least cessation of the fire. Our troops were
then made to cease firing, to lie down behind the fence, and, on the
enemy's approach to within fifteen paces, to spring up and pour in a
volley. This was so deadly, that the rebels fled in disorder, leaving
their dead and wounded, and could not be rallied again.

At Chickamauga, in 1863, the regiments of Hazen's brigade fired only by
volleys; every one of which, it is officially reported, was powerfully
effective in checking the enemy's attacks.

8. Nevertheless, it has been a common military saying, and supported
even by high authority, that the fire at will is _the only one possible
in action_. This assertion implies that the rank and file are not
sufficiently cool to reserve their fire, and that they must be kept
constantly occupied by the excitement, noise, and smoke of their own
fire, in order to make them remain steady in their ranks under that of
the enemy.

As applied to raw, undisciplined, or demoralized troops, the proposition
may be, to a great extent, true. But in reference to disciplined or
veteran troops, whose _morale_ has not been impaired, it will be found
disproved on almost every page of military history; from which a few
examples will be cited hereafter. For the present, one instance will
suffice; that of Colonel Willich's regiment of Thirty-second Indiana
Volunteers, at the battle of Shiloh, in April, 1862. While under fire,
their commander, perceiving their own fire to have become "a little
wild," caused them to cease firing, and then drilled them in the manual
of arms, which they went through as if on parade; after which, they
again opened on the enemy a fire, which is reported to have been
"deliberate, steady, and effective."

It may be here observed that, whenever troops lose their presence of
mind, there is no surer way of restoring it than by the repetition, by
their officers, in their usual tone, of any words of command they have
learned instinctively to obey on the drill-ground.

9. Infantry, when charged in position, should reserve its fire till it
can be made _with deadly effect_, as at the distance of fifty paces; and
the volleys should be instantly followed up by a countercharge with the
bayonet on the charging enemy. For, if our fire has staggered him, a
vigorous charge will complete his repulse; and if it has not, our only
chance of success is in suddenly taking the offensive ourselves.

Whilst awaiting his charge, we shall incur but little, if any, loss
from the enemy's fire; for the fire of troops advancing to attack is
usually of very little account.

The only disadvantage attending a volley just before we charge is, that,
as the smoke veils us from the enemy's view, it will rob us, to some
extent, of the moral effect of our swift advance.

But, in many cases, if the enemy see us awaiting his bayonet attack, and
reserving our fire to the very last, he loses resolution, relaxes his
speed, and then stops short, or retires.

At Cowpens, Colonel Howard broke and routed the British line which was
advancing to attack him, by reserving his fire to within thirty yards,
and then charging with the bayonet.

At the battle of Friedland, the Russian Imperial Guard charged on
Dupont's division with the bayonet. The French did not wait for them to
close, but rushed on with the bayonet themselves, and completely routed
them.

10. A volley concentrated upon the enemy's _regimental colors_ will
usually disable the color-guard and the men near it; and, if promptly
followed up by a charge, may enable us to capture the colors. This is
always an important advantage; for, by the loss of its colors, a
regiment is not only dispirited, but in danger of disorganization;
these being its proper rallying-point.

11. When infantry is acting as a _support to artillery_ which is
attacked, it should throw out sharpshooters to reply to the enemy's
skirmishers that are firing at the gunners and horses, whilst it engages
the compact mass by which it is itself attacked.

If the enemy should commit the blunder of attacking the battery with his
entire force, without detaching to engage the support, we should profit
by it by instantly charging him in flank; but taking care not to be led
away to any distance from the battery we are protecting.

12. Infantry, surrounded by the enemy, will often be able to _cut its
way through_ and escape. For this purpose, as the highest degree of
concentration is required, its formation should be in close column.


VI.--Defence against Artillery.

1. The best defence of infantry against artillery is by the fire of
_sharpshooters_ deployed as skirmishers, to pick off the gunners and the
horses; the main body, meanwhile, occupying the most sheltered locality
it can find.

2. Where no shelter is afforded by any natural obstacles, or by
irregularities of ground, it may be sometimes necessary to make the men
_lie down_.

But this expedient should be used as rarely as possible, on account of
its demoralizing tendency. Troops that have become accustomed to it
cannot be expected to bravely face the enemy; and the habit is very
rapidly formed. At Bull Run, in July, 1861, a whole company was seen to
grovel in the dust at the mere snapping of a percussion-cap of one of
their own muskets.

This demoralizing tendency does not exist, however, where troops lie
down only to enable their own artillery to fire over them. This was
shown at the battle of Pea Ridge, where several of our regiments lay on
the ground for two hours or more, while thirty of our guns were firing
over them. When, at last, this fire had silenced the enemy's guns, our
infantry then rose, charged him in a compact line, and drove him from
the field.

3. A line of infantry may _avoid_ cannon-shot by advancing or retiring
fifty paces. A column or a square would have to move this distance, or
more, according to its depth.

Ricochet shots may be avoided by moving fifty paces to the right or
left.

This shifting of position is but a temporary expedient, it is true, for
the enemy's guns will soon obtain the exact range again. But for this,
several trial-shots will be requisite, thus making the enemy lose time;
and, in battle, a few minutes lost or gained have often decided between
victory and defeat.

4. When the enemy opens an artillery fire on a square, _preparatory to a
cavalry charge_, his fire must cease when his cavalry approaches the
square; say, on its arriving within one hundred and fifty yards. To
avoid the artillery fire, the square may safely remain lying down until
the hostile cavalry has reached this point. For, as they will require
about half a minute to clear the intervening ground, the square will
still have time enough left to rise, align its ranks, and deliver a
volley before the cavalry reaches it.


VII.--Defence against Cavalry.

1. The discipline of infantry is never put to a severer test than when
it is required to resist a _charge of cavalry_, properly made. The moral
effect of a charge of a body of horse at full speed, on the troops
waiting to receive it, is like that caused by the swift approach of a
locomotive under full steam, seeming quite as irresistible. It would be
so in reality, but for the counter effect produced both on the horses
and their riders by the sight of the infantry standing firm and
reserving its fire. I have been told by an old cuirassier officer, who
served through the campaigns of Napoleon with distinguished bravery,
that there was no operation that his regiment so much dreaded as a
charge upon well-disciplined infantry.

2. This counter moral effect on the charging cavalry is the greater,
_the longer the infantry reserve their fire_; since, the less the
distance at which it is delivered, the more fatal will be its effects. A
volley at long range is not destructive enough to check the cavalry's
advance; while this effect has often been produced by the infantry
merely withholding its fire till the cavalry has approached very near;
and a volley delivered at the very last moment has, in by far the
greater number of instances, effectually repulsed the charge.

Infantry should, therefore, let cavalry approach to within forty paces,
or nearer still, and then give them a general volley.

At the battle of Neerwinden, in 1793, the Austrian cavalry was repulsed
by the French infantry under Dumouriez, by a volley poured in at the
very muzzles of the pieces.

At Austerlitz, a Russian cavalry charge on French infantry in line was
repulsed by a volley delivered so near, that it stretched four hundred
troopers on the ground. The rest dispersed in disorder to the right and
left.

3. The armor of cuirassiers is bullet-proof. To repel a charge of these
troops, therefore, it will be necessary to _aim at the horses_. Their
armor is so heavy, that the mere fall of the riders on the ground is
usually sufficient to disable them, as was the case with the French
cuirassiers at Waterloo.

4. Infantry in line, in two ranks even, may withstand cavalry, if in
compact order, and attacked _in front_. But the slightest cavalry charge
on the flank of a line will rout it.

At Quatre Bras, a French infantry line, advancing, repulsed a charge of
the Brunswicker Lancers under the Duke of Brunswick, by receiving it in
steadiness and good order, and then pouring in a destructive fire.

But, in the same battle, the Sixty-ninth British Regiment was instantly
rolled up and destroyed by a charge of French cuirassiers on its flank.

5. Where infantry is well disciplined, and its commander is cool and
prompt, it may sometimes _avoid the effect_ of a cavalry charge by other
means than its fire, or formation in square. At Talavera, a French
infantry division, drawn up in close column, seeing an English cavalry
regiment charging down upon them, avoided the shock by simply stepping
aside, thus allowing the cavalry to pass by them. A portion of the
charging troops wheeled round to follow them; but, by the cross-fire of
another division, and the charge of other cavalry, which fell upon it in
its confusion, it was completely annihilated.

6. A line of infantry charged by cavalry in flank, and so suddenly as to
allow no time to form square, could hardly escape destruction. It would
seem that the best course to be adopted in such a case would be to _open
the ranks_ by a rapid and simultaneous movement of both of them, thus
compelling the charging cavalry to ride between them. If the front rank
should then face about, this would bring the cavalry between two fires,
which might be poured in with most destructive effect.

But where the cavalry charges with a very wide front, or in line, this
manoeuvre might be difficult, or impossible.

7. Whenever an infantry line is charged by cavalry in front, and it is
doubtful whether it will stand the shock, the wisest course would seem
to be to make the men lie down, and let the charging cavalry _leap over
them_. This the horses will instinctively do, with but little risk of
injury to the men, provided they lie in a position parallel to the line
of battle, thus presenting the least possible depth. It is said that the
British infantry has sometimes done this, and risen up again immediately
after the cavalry had passed. The cavalry could thus be promptly taken
in rear.

8. In retreating, when threatened by cavalry, if there be a _long plain_
in our rear, we must retire slowly. But if cover, or ground unfavorable
to cavalry, be near, we must reach it as soon as possible.


VIII.--Squares.

1. In 1813, France was nearly exhausted of soldiers, so that Napoleon,
on hastily preparing for his campaign of that year, was obliged to
incorporate into his army a large number of raw conscripts, who had
scarcely begun their elementary drill. On the route to their respective
points of concentration, he accordingly ordered his columns to halt each
day, to practise _the three movements_ which he considered to be the
most important for infantry to be familiar with. These were, forming
battalions in square, deploying in line, and re-forming in column of
attack.

2. In the Austrian service, squares formed by a _column in mass_ are
considered preferable to hollow ones, on the supposition that though
horses will recoil from a dense mass, they may be easily brought to
break through a shallow formation, over which they can see the open
ground. But this theory seems to be refuted by numerous facts. A large
proportion of the formations that have successfully repulsed cavalry,
since the beginning of this century, have been hollow squares.

3. The rule laid down in the Tactics (Par. 143, Skirmishers), directing
the skirmishers, in rallying on the square, to "come to a ready without
command, and fire upon the enemy; which will also be done by the
reserve, as soon as it is unmasked by the skirmishers," is an unsound
one, for a compliance with it would be dangerous. A square cannot expect
to repulse cavalry by an irregular fire at will, but only by
well-directed _volleys_. If cavalry charge a square firing irregularly,
it will probably rout it. On the other hand, if a square wait coolly
till the cavalry is at twenty paces, its volley will be murderous. At
Waterloo, the Allied squares that reserved their fire till the French
cavalry had arrived at from twenty to forty paces, invariably repulsed
it. At that battle, Ney led eleven cavalry charges against the British
squares, every one of which failed.

At the opening of the campaign of 1813, Napoleon had, comparatively, but
a handful of cavalry; so few, that they had to keep close to their
infantry for protection. In crossing the plains of Lutzen, a large and
splendid cavalry force of the Allies, supported by infantry and by
horse-artillery, made an attack on Ney's corps, which consisted chiefly
of young and raw recruits, who saw an enemy for the first time. The
situation was extremely dangerous, and Ney and his principal generals
threw themselves into the squares to encourage them. By volleys
delivered at a signal, the enemy's charges were all repulsed, and the
conscripts acquired great confidence from the ease with which this was
done. Ney then broke up his squares, and, pursuing the enemy in columns,
completed their repulse.

At Auerstadt, in 1806, Davoust's French squares had to sustain a long
succession of charges from ten thousand Prussian horse. By reserving
their fire, each time, to within thirty or forty paces, its effect was
so deadly, that a rampart of dead and disabled men and horses was soon
formed around the squares, and the charges were all repulsed.

So, at Jena, on the same day, Ney, posted in a square, allowed the
Prussian cuirassiers to charge up to within fifteen or twenty paces,
when the front attacked, at his word of command, poured in a fire which
completely repulsed the charge, strewing the whole ground with dead and
wounded. The Prussian cavalry, in that battle, are said to have been
"terrified at the sight of a motionless infantry reserving its fire."

Again, at Mount Tabor, in 1798, General Kleber, marching with an
infantry division of only three thousand men, over an immense sandy
plain, was attacked by twelve thousand Turkish horse. The French squares
resisted their successive charges for six hours, by means of volleys
reserved till the enemy were at the very muzzles of their guns; which
soon built up a rampart around them of men and horses. Bonaparte then
arrived with another division. Dividing it into two squares, he rapidly
advanced them in such a manner as to enclose the Turks in a kind of
triangle; when, by a sudden fire upon them from three points at once, he
drove them upon each other in confusion, making them flee in every
direction.

It may be observed, that advancing or manoeuvring in squares is
practicable only on open and level plains, like the sandy deserts of
Egypt and Syria.

4. The best reliance of an infantry square being, therefore, on its fire
by volleys, the men should be instructed to come to a _charge bayonet_,
instead of a "ready," immediately on forming square. From this latter
position, there would be much greater danger of the volley being
prematurely delivered. The fire of a single excited man will usually be
followed by a general discharge.

5. It may be often advisable that the volley should be delivered by
_both ranks_ at once, and not by a single one. Par. 1191, School of the
Battalion, directing that "a battalion, in square, will never use any
other than the fire by file, or by rank," should therefore be amended.

6. Moreover, in view of what has been said as to volley-firing, and of
the examples that have been cited in confirmation, there is reason to
doubt the wisdom of the direction contained in Par. 67, School of the
Company: "The fire by file being that which is most frequently used
against an enemy, it is highly important that it be rendered perfectly
familiar to the troops. The instructor will, therefore, give it _almost
exclusive preference_."

The fire by file, after its commencement, becomes a mere individual fire
at will. Independently of the general ineffectiveness of this kind of
fire, one would have supposed that the instructor's attention should be
rather directed to accustoming the men to the more difficult reserved
fire by volleys, instead of practising them almost exclusively in a fire
which, once learned, they will use instinctively, and without any
practice at all.

7. Infantry _breech-loading weapons_ would be very useful to troops in
square, when charged by cavalry; since, being rapidly reloaded, they
would enable the square to repulse, with a volley, each subdivision
successively, where the charging column is formed at the usual
distances. But it is doubtful whether, on the whole, these weapons are
preferable to muzzle-loaders. Certain it is, that they exhaust the
ammunition much more rapidly, and so cause a suspension of fire, and a
withdrawal from the line of battle, till a new supply can arrive. And,
to obtain this new supply, a long time is generally required; infantry
ammunition being usually carried in the second, or more distant
ammunition train, instead of the first, or nearest one, as it ought to
be.

8. Although a reserved fire is much the most reliable in repulsing
cavalry, the men may sometimes be ordered to commence the fire at a
_considerable distance_. In such case, they should be instructed to aim
at the horses, instead of their riders, as affording a better mark.

9. European cavalry is often practised, on arriving within four hundred
yards, or effective grape-shot distance, of an infantry square, to halt,
and then open at the centre, unmasking a battery of horse-artillery,
which plays for a certain time on the square, when the cavalry closes
again, and charges.

A square, however, attacked in this manner, is _not in so much danger_
of being broken as might be imagined. The enemy's guns, after being
unmasked, would usually require several trial rounds to get the exact
range; and our sharpshooters, who could safely be thrown forward one
hundred yards, with the new rifled arms, ought, in the mean time, to
inflict such loss on the cavalry, as well as on the battery, as to cause
it either to retire, or to charge feebly, and, therefore, ineffectively.
At the very worst, the square would have ample time to re-form its
ranks, and deliver a deadly volley before the cavalry could reach it, as
it also would if this operation were attempted much nearer, say at two
hundred yards. In this last case, a few volleys from the square itself,
with the new arms, would probably be destructive enough to prevent the
charge altogether.

10. It is hardly necessary to observe, that troops formed in square,
when charged by cavalry, can secure their safety only by _standing
firm_. A single opening will suffice to let in the enemy, who will then
easily ride over the square, and cut it in pieces. Whereas, if the
square remain unbroken, cavalry can inflict upon it no loss, or but a
trifling one.

11. In repulsing a cavalry charge, coolness and presence of mind will
sometimes enable troops to accomplish _extraordinary results_.

At Quatre Bras, the square of the Forty-second Highlanders was not
completed, the companies still running in to form the rear face, when
the enemy's leading troop entered. But the square, nevertheless,
finished its formation; and the French cavalry, caught, as it were, in a
net, was soon destroyed by the concentrated fire of all the fronts,
which had faced inward.

In the same battle, the Forty-fourth British Regiment, standing in line
in two ranks, was suddenly charged in rear by the French Lancers, who
had dashed round one of their flanks for that purpose. The rear rank
suddenly faced about, and, at a very short distance, poured in a deadly
fire, which put them into confusion. On their way back to re-form, the
front rank, in its turn, gave them a volley, which destroyed great
numbers of them, and completed their rout.

12. Even when a square has been actually broken, it is _not necessarily
lost_. If the troops are brave and well disciplined, it may sometimes be
rallied again, re-formed, and made to repulse the attacking cavalry, as
was the case with some of the Allied squares at Waterloo.

So, at the battle of Pultusk, in 1806, a French battalion that had been
broken and overthrown by Russian cavalry, immediately rallied, fell on
the troopers floundering in the mud, and dispatched them.

So, at the battle of Krasnoe, in 1812, a large Russian square was
retreating before the French cavalry masses. Occasionally, in order to
pass a narrow defile, it was obliged, temporarily, to break the square.
At these times the French made furious charges, penetrated into the
column, and captured men and guns. But as soon as the defile was passed,
the Russians instantly re-formed the square, and continued their
retreat. They finally succeeded in reaching Korytnia, after killing and
wounding some four hundred or five hundred of the French; though with
the loss of eight guns, one thousand prisoners, and seven hundred or
eight hundred _hors de combat_, out of five thousand or six thousand
men.


IX.--Skirmishers.

We shall consider--

First, THEIR USE.

Secondly, HOW THEY ARE POSTED.

Thirdly, HOW THEY ARE HANDLED.

Fourthly, RULES FOR INDIVIDUAL SKIRMISHERS.


A. THEIR USE.

1. In approaching the enemy through a wooded or broken country,
skirmishers thrown out in advance, and on the flanks of the leading
column, are absolutely indispensable, in order to _reconnoitre the
ground_, and prevent a surprise.

2. Skirmishers _protect_ the main body, or any particular portion of it,
from attack while manoeuvring.

A regiment, or a brigade, in covered ground, whether the enemy be
visible or not, should never change its position in battle, or
manoeuvre, without the protection of a skirmishing line.

3. They furnish a screen, behind which the main body may _hide its
movements_, and be enabled to attack at an unexpected point.

4. Where a ravine, a wood, or other similar obstacle causes _a break in
our line of battle_, by occupying it with skirmishers we guard it
against penetration by the enemy, and connect the separated corps with
each other.

5. Skirmishers may be used to alarm the enemy at a point where he
expected no attack, and thus _create a diversion_.

6. By their attack at various points, they serve to _unmask the enemy's
position_.

7. They may be employed to _open the way for a charge_ with the bayonet.

At the battle of Stone River, the rebels, on one occasion, advanced in
line, with a double column in rear of each wing, preceded by a double
line of skirmishers, who reserved their fire till close to our line,
when they halted, poured in a murderous fire, and fell back on their
main body, which then rushed forward. Both our first and second lines,
staggered by this sudden and destructive fire, were swept from the
ground.

8. Skirmishers have been sometimes thrown forward to _test the spirit
and disposition_ of the enemy.

At Biberach, in 1800, the French general St. Cyr, after having carried
the place, and driven the Austrians through the defile in rear of it
back upon their main body, posted on the heights of Wittenburg, sent
forward a strong line of skirmishers to open fire on them, with the view
of ascertaining their temper and disposition after their vanguard had
been defeated and driven in. This drew forth a general and continued
discharge, like that which demoralized troops are apt to indulge in to
keep up their spirits by their own noise. Seeing this, St. Cyr instantly
prepared to charge, although he had with him but twenty thousand men,
and the Austrians numbered sixty thousand, and were in a strong
position. The result justified his decision; for, on the near approach
of the French, the Austrians fired a volley or two and then retreated in
confusion.

9. Skirmishers should _accompany columns of attack_; for--

(1.) They increase the confidence of the troops they accompany. Placed
between the columns, they advance boldly because the columns advance,
and the columns advance boldly because the skirmishers do.

(2.) Preceding the columns, by driving back the enemy's skirmishers, and
diverting his fire to themselves, they keep the attacking columns as
free from loss as possible till the shock.

They, moreover, serve to annoy the troops we are about to attack, by the
incessant sharp buzzing of their deadly bullets among them, like so many
bees, killing some and disabling others; and this, sometimes, to such a
degree as to demoralize them.

It is said that, at Waterloo, the swarms of skirmishers that covered the
French attacking columns so galled and excited the stationary columns
and squares of some of the Allies, as to nearly drive them from the
field.

(3.) On the flanks of a column, they cover them from attack.

(4.) They draw the enemy's fire prematurely, and thus render it
comparatively ineffective.

(5.) They prevent the columns from halting to deploy and fire.

(6.) They may sometimes conceal the direction of the march of the
attacking column, and even seize the guns that have been playing on it.

10. In defence, if they can _encircle the enemy's advancing column_,
they may destroy it by their concentric fire.

11. In a retreat, skirmishers _cover the rear_, so long as the enemy
attacks without cavalry.

12. The NEW RIFLED ARMS have obviously much increased the effectiveness
of skirmishers.


B. HOW POSTED.

1. They should be always _near enough to the main body to be supported
by it_, if hard pressed, and also to enable the main body to profit at
once of any advantage that may have been gained by them.

2. They should _cover the main body_, both in front and in flank, except
where the ground may render this impracticable or unnecessary; and, in
defensive positions, they should occupy every point from which the
enemy's skirmishers might annoy us.

3. In a defensive combat, they should be so posted as to take the
enemy's attack _in flank_:

(1.) Because their fire will be thus the more destructive; and--

(2.) They will not be exposed to be driven back by the enemy's fire, or
by his advance.

4. If thrown into an enclosure, they must have _an easy exit_.
Skirmishers feeling themselves in danger of being cut off, will lose
somewhat of that coolness which is so essential to their efficiency.

5. They should not be kept stationary _behind a straight line_, as a
wall, a fence, or a hedge; for this would expose them to enfilade.

6. Skirmishers are only auxiliary to the main force, and are not
capable, by themselves, of effecting any decisive result. Therefore, in
order not to exhaust the men, _heavy_ skirmishing lines should not be
used, except to lead a decided advance, or to repel one.

7. The principle is, to post skirmishers so as to give them the _maximum
of shelter_, whilst inflicting the _maximum of loss_ on the enemy. This
applies to the placing of the whole line, and to the separate groups.
The way skirmishers produce their effect is by sharpshooting, which
requires calmness; and the more completely sheltered they are, the
calmer they will be, and the more deadly will be their aim.


C. HOW HANDLED.

1. Deploy them _before coming within range of musketry_; for infantry in
compact order is a good target for the enemy.

2. They should be kept _well in hand_; especially at the moment of
success, when they are in danger of rushing headlong to destruction.

3. Coming upon the enemy's main body, they should _occupy him in front
and flank_ till our own main body gets up.

4. Except in urgent cases, never deploy a line of skirmishers _on a
run_; for this makes them lose breath and calmness, and, with their
calmness, their accuracy of aim.

So, after deployment, avoid all rapid and violent movements.

5. Skirmishers become exhausted after long firing. The longer they
continue out, the worse they shoot. Therefore, _relieve them often_.

6. Skirmishers should be accustomed to _lie down_ at a given signal; as
it is sometimes very important that both our artillery and infantry
should be able to fire over them.

7. In retreat, skirmishers occupy every favorable point for _holding the
enemy in check_.


D. RULES FOR INDIVIDUAL SKIRMISHERS.

1. In advancing, in retreat, or at a halt, use _every cover_ that
presents itself.

2. Preserve _the alignment and the intervals_, so far as possible. On
open ground, this may be done perfectly. In woods, skirmishers should
never, for a moment, lose sight of each other.

3. The security of the _flanks_ should be looked out for by the men near
them.

4. Run over _exposed ground_ as quickly as possible.

5. Approach the _crest of a hill_ with great caution.

6. If threatened by _artillery alone_, advance and kill off the men and
horses before they get into battery. When the pieces have got into
battery, lie down, if on exposed ground, till they limber up again, and
then recommence the fire.

7. A skirmisher, with the new rifled arms, ought, at five hundred yards,
to be _more than a match for a gun_; for, in men and horses, he has a
much larger target than the gun has in him.

Again, with the new rifle shells, he may be able to blow up a caisson.

8. Neither should a skirmisher have much to fear from a _single
horseman_. With his bayonet fixed, he would usually be able to defend
himself successfully against the trooper, whose sabre is the shorter
weapon of the two; more especially, if he will take care to keep on the
trooper's left, which is his exposed side.

9. Never lose your calmness. Your power consists, not in rapid firing,
but in the _accuracy of your aim_. Avoid all hurried and violent
movements; and never raise your gun till sure of a shot.

10. The aim, according to the Tactics, is made by bringing the gun down,
instead of raising it up. However little the soldier may be excited, he
will be apt to pull the trigger more or less too soon; that is, while
the muzzle is yet too elevated. This is the reason why infantry missiles
usually _fly too high_. The difficulty would not be obviated by causing
the aim to be made by raising the piece; for then the same disturbing
cause already mentioned, the soldier's excitement, would make the shots
fly as much too low, as they now fly too high.

Rapid firing is another cause of this incompleteness of aim. Infantry
firing is already too rapid to be effective; so that what is claimed for
the new breech-loading weapons as an advantage, that they increase the
rapidity of fire, furnishes, on the contrary, a strong objection to
them. The effectiveness of the fire of a sharp-shooter, especially, will
be usually in inverse, instead of direct proportion to the number of
shots he delivers in a given time.

In view of this, and of the tendency to pull the trigger before the
muzzle is sufficiently depressed, it has become an established maxim, to

   "Aim low,
   Fire slow"




TACTICAL USE OF ARTILLERY.


The subject will be treated under the following heads:--

    I.--HOW POSTED WITH RESPECT TO THE GROUND.
   II.--HOW POSTED WITH RESPECT TO OUR OWN TROOPS.
  III.--HOW POSTED WITH RESPECT TO THE ENEMY.
   IV.--POSTING OF BATTERIES AND PIECES AS BETWEEN THEMSELVES.
    V.--HOW USED.
   VI.--ITS FIRE.
  VII.--ITS SUPPORTS.


I.--How posted with respect to the Ground.

1. Artillery has a much longer range than musketry. In order to avail
ourselves of this advantage, we must so post it as to overlook all the
ground to which its utmost range extends. It therefore requires _an
elevated position_.

2. It has been considered an additional advantage of a commanding
position for artillery, that it enables our guns to cover our infantry,
attacking or attacked, by _firing over their heads_.

This was done by the French at Waterloo, apparently with great effect.
But the advantage is a doubtful one; for firing over our own troops,
especially with cast-shot or shell, is very dangerous to them, and is
apt to intimidate them. It moreover furnishes to the enemy a double
target. The shot which miss our troops will be apt to fall among the
guns behind them; and some of those which do not reach the guns, will
probably take effect among the troops in front of them.

3. But _very high_ points are unfavorable positions for batteries.
Batteries so placed would not command the ground immediately below them;
as guns cannot be depressed to fire below a certain angle without soon
destroying their carriages. And this would facilitate their capture;
for, once arrived on the ground near them, the assailants could not be
injured by their fire. It has been estimated that the slope in front of
a battery should not exceed one perpendicular to fifteen base.

4. When guns have to be used as a support to other parts of the line,
which is often the case, their capture might lead to serious
consequences. They should therefore have the ground clear of all
obstacles which may _mask their fire_, not only in front, but to their
right and left.

5. Although the most favorable position for guns is an eminence sloping
gradually towards the enemy, an _open and level plain_ is by no means an
unfavorable one; for, on such ground, the enemy will be visible at a
great distance, and our shot may act by ricochet, which causes more
destruction than ordinary point-blank firing.

For ricochet, firm and even ground is requisite; on soft or rough ground
it is not attainable.

6. In enfilading the enemy's position, or in raking his advancing
columns from head to rear, a _grazing fire_ is the most destructive that
can be used. This consists of a long succession of ricochets at low
heights. Where the ground is level and firm, we can obtain this fire at
a short distance from the enemy; as, on such ground, ricochet shots do
not rise much. But where the ground is uneven, to obtain such a fire, a
more distant position will be requisite.

7. _Muddy_ ground is unfavorable for artillery. Over such ground, its
carriages move slowly, and its fire is less effective. Balls cannot
ricochet; and shells often sink into the mud, and thus are either
extinguished or explode with but little effect.

Napoleon depended so much on his artillery at Waterloo that, although
every moment was precious, he delayed commencing the battle till his
chief of artillery had reported the ground, which had been covered by a
soaking rain, to be sufficiently dry for the movements and effectiveness
of that arm. The three hours' delay thus caused, would have sufficed him
to crush Wellington's army before the arrival of the Prussians.

8. _Stony_ ground is a bad location for a battery; for the enemy's shot
will scatter the stones around it with more or less fatal effect.

9. _Rough_ or _uneven_ ground immediately in front of a battery is not
objectionable, as it will stop the enemy's shot.

10. A battery, when it is possible to avoid it, should not be posted
within musket range of _woods_, _bushes_, _ravines_, _hedges_,
_ditches_, or other cover from which the enemy's sharpshooters might
kill off the gunners, or, by a sudden dash, capture the guns.

11. To prevent the enemy from approaching a battery under cover, it
should be so placed as to be able to sweep all _villages_, _hollows_,
and _woods_, in front and in flank.

12. In taking up a position, a battery should avail itself of all
_inequalities of the ground_, for the shelter of its pieces and gunners,
or of its limbers and caissons, at least.

For the same purpose, a battery posted on an eminence should have its
pieces some ten paces behind its crest.

13. Where the ground affords no shelter, and where the position of the
guns is not likely to be changed, it may be worth while to cover them by
an _épaulement_ or breastwork, some three feet, or more, high.


II.--How posted with respect to our own Troops.

1. In order to be ready to support the flanks of our attacking columns,
and to aid in the defence in every part of the field, batteries should
be placed at _several different points_ in the line of battle.

2. In a defensive battle especially, as it is uncertain on what point
the enemy will mass his principal attack, the artillery should usually
be distributed _through the whole line_.

3. A line of battle has been compared to the _front of a fortification_,
of which the infantry is the curtain, and the artillery batteries the
bastions.

4. The _lighter_ guns should be placed on the _salient_ points of our
line, from which they can be more easily withdrawn; the heavier guns,
constituting the stationary batteries, on the more retired points.

5. Pieces should not be placed _in prolongation with troops_; for this
would be giving the enemy a double mark. Artillery posted in front of
other troops will draw a fire on them. When a battery must be placed in
front of the line, let the infantry in rear of it clear the ground by
ploying into double columns.

6. Never place artillery so as to _impede the movements of the other two
arms_. A battery posted in front of the centre would often hamper the
movements of the infantry; besides being peculiarly exposed to a
converging fire from the enemy's batteries.

7. The safest position for a battery is on that wing which is most
secure from a flank attack.

But guns should re-enforce the weaker points, thus making the enemy
attack the strongest ones.

Therefore, _where a wing is weak_, place the largest number of guns
there, to support it. If we have one wing entirely uncovered, of four
batteries, for instance, we should give three to the uncovered wing.

8. Of the heavy batteries, one, at least, should be placed in the first
line, so that we may be able to open an effective fire on the enemy at
the _earliest possible moment_.

9. The prompt use, at the proper moment, of the reserve, may decide the
battle. The movements of heavy artillery, therefore, are too slow for
the reserve, which should have most of the light pieces. _Horse
artillery_ is especially suitable for it.

10. Guns near an infantry square should be posted at its _angles_. If
the square is charged by cavalry, the gunners run into the square, after
filling their ammunition pouches, which they take in with them, as well
as their sponges and other equipments. The limbers and caissons are sent
to the rear; or, if there is no time to do this, they may be brought
into the square. If this is impossible, they may be formed into a
barricade.

At Waterloo, on the French cavalry's retiring from their charges on the
enemy's squares, the British gunners rushed out from the squares in
which they had taken refuge, and plied their guns on the retiring
squadrons.


III.--How posted with respect to the Enemy.

1. If the enemy's batteries are concentrated in one position, by placing
our own batteries properly we may obtain a powerful _cross-fire_ on
them.

2. It is always advantageous to so dispose our batteries as to take
those of the enemy _in enfilade_, or obliquely (_en écharpe_, as it is
called).

At the battle of Murfreesboro', in December, 1862, a rebel battery,
being taken in enfilade by one of our own, was silenced in about five
minutes.

3. So, also, if we can obtain an oblique or enfilading fire _on his
troops_, it will be very destructive. A flanking battery, raking the
enemy's position, is often enough, of itself, to decide a battle.

Thus, the battle of Chippewa was finally decided by our getting a gun or
two in a flanking position, enabling us to enfilade the British line.

So, at the battle of Shiloh, the rebels' triumphant advance on the
evening of the first day was effectually checked by the fire of our
gun-boats Tyler and Lexington, which had taken an enfilading position
opposite their right flank.

4. For this reason, we must never post one of our own batteries so that
the enemy's guns will take it _obliquely_, or _in flank_; unless,
indeed, by doing so, we may probably obtain some important and decisive
effect before it can be destroyed, or made unserviceable.

5. Batteries should be so placed as to _command the whole ground in our
front_, even almost up to our bayonets, and so as to be able to direct
their fire towards every point; at all events, so that a fire can be
kept up on the enemy till he is within short musket-range.

It is manifest that the best position for a battery, to enable it to
effectually cover the entire ground in our front, would not be in our
line of battle, but in advance of one of its flanks, from which it could
take the enemy's troops advancing over it, in enfilade.

6. Artillery fire from _an unexpected quarter_ always has a powerful
moral effect. Two guns, even, hoisted up to a place where the enemy does
not dream of there being any, may have a decisive effect.


IV.--Posting of Batteries and of Pieces as between themselves.

1. The best mode of posting batteries is in the form of a crescent, its
horns pointing towards the enemy, or forming the sides of a re-entering
angle; for this gives a _convergent fire_ to the enemy's divergent one.

Its inconvenience is, the exposure of its flanks to attack, or to
enfilade. Therefore, when such a position is adopted, its flanks must be
protected by natural obstacles or by artificial defences.

2. Batteries, or parts of batteries, should be at _supporting distances_
from each other; that is, not over six hundred yards apart, so as to
effectually cover the whole ground between them, in case of need, with
grape and canister. When rifled guns are used, this distance may be
increased.

3. _A long line of guns_ in our line of battle is objectionable; for, if
it should become necessary to withdraw them, they would leave a
dangerous interval.

4. It is dangerous to collect _a great many pieces in one battery_,
especially in the beginning of an action, when the enemy is fresh, for
it strongly tempts him to capture it. When used, such a battery should
have powerful supports to protect it, or should be sheltered by a
village, a defile, or other cover, occupied beforehand.

5. Although, to be used offensively, guns should be in strong masses, in
order to strike a decisive blow on some single point; this is by no
means the case when _used defensively_; for,

(1.) It is only when guns are more or less scattered over different
parts of the field, that they can be made to give a cross-fire on the
enemy's advancing columns, or on any part of his line.

(2.) If the position where they are massed does not happen to be
attacked, they become useless, while stripping the rest of the line.

(3.) If they are captured, all the artillery is lost at once, as
happened to the Austrians at the battle of Leuthen, causing their
defeat.

6. A certain number of pieces of horse-artillery must always be _kept in
reserve_, so that, if an artillery fire at any point should be suddenly
wanted, it may be furnished with the least possible delay.

7. Guns of _various calibres_ should never be in the same battery, to
prevent confusion as to the respective ranges, and in the supply of
their ammunition.

8. An independent section or battery should never consist of _howitzers
alone_, for the proper fire of these pieces is too slow to be effective
in repulsing an attack on them.

9. There should always be _wide intervals_ between the pieces; otherwise
the battery would offer too good a mark to the enemy.


V.--How used.

First, GENERALLY.
Secondly, IN OFFENSIVE COMBAT.
Thirdly, IN DEFENSIVE COMBAT.
Fourthly, AGAINST INFANTRY.
Fifthly, AGAINST CAVALRY.
Lastly, AGAINST ARTILLERY.


A. GENERALLY.

1. So far as is possible, guns should be kept _hidden from the enemy_
till the moment of opening on him. They may be masked by the ground, or
other cover, natural or artificial, or by troops placed in front of
them. The surprise will add much to their effect. Moreover, concealed,
they will be less exposed to be taken. Nothing discourages troops more
than the loss of a battery at the beginning of an action.

2. A desultory and indiscriminate artillery fire will accomplish
nothing. To effect any thing important, it must be _concentrated on some
object_; and the fire must be persevered in till the desired effect has
been produced.

3. It is a general principle that artillery should not reply to the
enemy's batteries, unless compelled to by their effect on our own
troops. To obtain the most decisive effects from artillery fire, it
should be directed _on the enemy's troops_, instead of his guns.

4. If it should become advisable to silence one of his batteries, it
will be done more promptly and effectually by the employment, for this
purpose, of _two_ of our own batteries, than of a single one.

5. There is usually great advantage in keeping our batteries constantly
_shifting their position_; for then--

(1.) They have the effect of a surprise, by opening on the enemy at
some unexpected point.

(2.) They make the enemy believe our guns to be more numerous than they
really are.

(3.) They are in less danger of being captured.

But these changes of position are attended with this inconvenience, that
they expose the horses to be taken in flank by the enemy's batteries and
sharpshooters.

6. The movements of a battery in the field should be _as rapid as
possible_; for, while moving, it is helpless and exposed.

Moreover, celerity of movement and accuracy of fire will often more than
compensate for inferiority in the number of guns; as was the case at the
battle of Palo Alto, in the Mexican War, where the enemy's guns
outnumbered ours two to one.


B. IN OFFENSIVE COMBAT.

1. When used to _prepare for an attack_ of infantry or cavalry,
artillery concentrates as much fire as possible on the point where the
attack is to be made, in order to overcome the resistance there, and
thus make success easy.

2. When there are several points on which our fire should be directed,
we must not batter them all at once, but concentrate our whole fire on
them _in succession_.

3. In attack, artillery should _not be split up_ among different
brigades or divisions; else no decisive result can be expected from it.
Whole batteries, used together, will have a more telling effect than if
scattered over the field in separate sections.

In no case should less than two pieces be used together; for, while one
piece is being loaded, the piece and its gunners need the protection of
another one ready to be discharged.

4. Pieces in support of an infantry column of attack should never be in
its rear, but _on its flanks_, near its head, in which position it will
best encourage the infantry. But if a battery have already a position
from which it can afford to the attack effective assistance, it should
remain in it; sending a few pieces to accompany the infantry, which
always greatly values artillery support.

5. Powerful effects may be produced by the _sudden assemblage of a great
number of guns_ on some particular point. This was a favorite
manoeuvre of Napoleon; who, by his rapid concentration of immense
batteries of light artillery on the important point, usually obtained
the most decisive results. At Wagram, for instance, when Macdonald's
column was ready to make its great charge on the Austrian centre,
Napoleon suddenly massed one hundred guns in front of his own centre,
and made it advance in double column at a trot, then deploy into line on
the leading section, and concentrate its fire on the villages forming
the keys to the enemy's position, in front of his right and left wings
respectively; each battery opening its fire on arriving at half-range
distance. The effect was overwhelming.

6. The _nearer_ artillery delivers its fire, the more powerful, of
course, are its effects. Horse artillery, in sufficient strength,
attacking the enemy at short grape-shot distance, say within three
hundred or four hundred yards, may lose half its pieces, but with the
other half it will probably decide the battle at that point.

At Palo Alto, Duncan's rapid closing with his guns to less than half
range, drove back the Mexican right wing, which could not stand the
destructive fire.

7. _Horse artillery_ does not usually attempt to follow up cavalry in
its attack; but takes a position to cover its retreat, if repulsed, or
to push forward in support, in case of success.

8. When cavalry has to _debouch from a defile_, horse artillery may
render it most effectual assistance, by taking a position that will
enable the cavalry to form without fear of being charged and destroyed
while forming.


C. IN DEFENSIVE COMBAT.

1. Artillery should always reserve its fire till the enemy's _real
attack_.

2. It should play on that portion of the hostile force that _threatens
us most_.

3. It should wait till the enemy has come within _destructive distance_,
and then open on his columns with a concentrated fire.

4. It should protect our troops _while manoeuvring_, and accompany
them in retreat.

5. We must _subdivide our batteries_ whenever we wish to obtain
cross-fires on a _débouché_, or on the head of an advancing column, or
on the ground in front of a weak part of our line. By so doing, we
compel the enemy to divide his own artillery in order to reply to our
fire.

6. A _sudden concentration_ of a great number of guns at some particular
point may be used with the same decisive effect in a defensive, as in
an offensive battle; though in this case, artillery plays, for the time
being, a part strictly offensive.

At the battle of Friedland, where the French were attacked by the
Russians in overwhelming numbers, Ney's corps was driven back by a
terrific concentrated fire, in front and in flank, from the Russian
batteries on the opposite side of the river; its own artillery being too
feeble to stand before them. Seeing this, Napoleon instantly ordered all
the guns of the different divisions of the corps next to Ney's, on the
left, to be united and thrown in one mass in front of Ney's corps.
Taking post at some hundred paces in front, these batteries, by their
powerful fire, soon silenced the Russian batteries; then advancing on
the Russian troops that had crossed the river to within grape-shot
range, they made frightful havoc in their deep masses. The French
infantry, profiting by this, rushed forward and captured the village of
Friedland, driving the enemy in their front over the bridges, which they
then burned. This was decisive of the battle; for the whole Russian army
was then driven into the river.

So, at the battle of Kunersdorff, in 1759, after Frederick's left and
centre had driven the Russians, and captured seventy guns and many
prisoners, Soltikoff promptly massed the whole artillery of his right
wing at a single point behind a ravine, which, by its concentrated fire,
swept away the flower of the Prussian army in their efforts to force its
passage; and Frederick was badly defeated.

7. When compelled to retreat, guns should _retire successively_, in
echelons of batteries, half-batteries, or sections, in order that the
fire of one may cover the limbering up and retreat of another.

Besides the mutual support thereby afforded, these successive
face-abouts of artillery have a powerful moral effect on the pursuing
enemy, already more or less disorganized by success.

It would be well for some pieces in each echelon to be kept loaded with
canister, so as to drive the enemy back if he should press very close.

8. The protection afforded by artillery in retreat is very powerful, as
it keeps the enemy constantly _at a distance_.

A fine example of the use of it for this purpose occurred just before
the battle of Pea Ridge, in March, 1862. A rear-guard of six hundred
men, under General Sigel, was retreating before a force of four
regiments of infantry and cavalry, that followed and attacked it on
every side. Sigel disposed his guns in echelons, the one of which
nearest the enemy played on his attacking squadrons with grape and
shell, which suddenly checked them. Instantly profiting by their
temporary hesitation, the echelon limbered up and galloped away to
another position, while the next echelon, again checking the enemy by
its fire, followed its example. By this means, Sigel, cutting his way
through a vastly superior force, succeeded, after a retreat of ten
miles, in rejoining the main body with but trifling loss.

9. If driven to the last extremity, the gunners should try, at least, to
_save the horses_, and to blow up the caissons they have to abandon.

At the battle of La Rothière, in 1814, where Napoleon, with thirty-two
thousand men, was overwhelmed by one hundred thousand Allies, and was
obliged to leave fifty guns on the field, he succeeded in bringing off
all his gunners and horses.


D. AGAINST INFANTRY.

1. It is an important rule that artillery should play on the enemy's
_troops_, without attending to his batteries, except in urgent cases.

2. Against a _deployed line_, whether marching by the front or by a
flank, case-shot, that is, grape, canister, and spherical case
(sometimes called _shrapnel_), are most suitable; as these all scatter,
right and left, to a considerable distance.

The best effect of canister is within two hundred yards. Beyond three
hundred and fifty yards, it should not be used.

The best effect of grape is within four hundred yards. Over six hundred
yards, it is not very effective.

Spherical case is effective at much greater distances, its range being
nearly equal to that of solid shot.

Against a line of infantry at a greater distance than six hundred yards,
spherical case should be used, chiefly, if not exclusively; as being
more likely to be effective than ball.

3. But case-shot are _unsuitable against a column_, as they consist of a
number of small balls which have not momentum enough to penetrate into
it to any depth. When the enemy advances in columns, solid shot should
plough through them from head to rear, a cross-fire being obtained upon
them when possible.

4. Especially should _round-shot_ be used against a close column rushing
to attack us through a defile. Grape and canister might sweep down the
leading ranks, but the mass of the column sees not the destructive
effect; and being carried forward by the pressure of the ranks behind,
continues to rush on till the battery is carried, though with more or
less loss.

At the battle of Seven Pines, on one occasion, when the rebels were
advancing in close columns, they were plied with grape and canister from
two of our batteries with but little effect. Every discharge made wide
gaps in their leading ranks, but these were instantly filled again, and
the columns pressed on.

A round-shot, on the other hand, comes shrieking and tearing its way
through the entire column, carrying destruction to the very rear-most
ranks. The hesitation produced is not limited to the leading ranks, but
extends throughout the column. Thus both the actual and the moral effect
of ball on a close column is much superior to that of grape or canister.

At the bridge of Lodi, the Austrian gunners plied the French column
with grape. If they had used round-shot instead, it is doubtful whether
Bonaparte would have succeeded in carrying the bridge.

5. But a direct fire with ball on the head of a column of attack would
be much assisted by the fire of a few light pieces taking it _in flank_.
And, for this fire in flank, case-shot would be powerfully effective;
for, from their wide scattering, both their actual and their moral
effects would extend through the whole column, from front to rear.

6. A battery with _guns enough to keep up a continuous fire_ has little
to fear from an open attack on it by infantry alone. Napoleon observed
that no infantry, without artillery, can march one thousand yards on a
battery of sixteen guns, well directed and served; for, before clearing
two-thirds of the way, they will have been all killed, wounded, or
dispersed.

This remark was made in reference to smooth-bore guns; the new rifled
guns should be still more destructive.

7. _Against skirmishers_, as they offer but a poor mark for ball, grape
and canister should alone be used.

E. AGAINST CAVALRY.

1. The ground round a battery should be so obstructed as to _prevent the
enemy's cavalry from closing on it_; but in the case of a light battery,
intended for manoeuvre, so far only as this can be done without
impeding the movements of the battery itself.

2. On being threatened by cavalry, a light battery may sometimes
promptly change its position to one where the cavalry would attack it
_at great disadvantage_. For instance, if posted on an eminence, and
cavalry should attempt to carry it by charging up the slope, instead of
awaiting the charge in a position which would allow the cavalry to
recover breath, and form on the height, it might run its pieces forward
to the very brow of the slope, where the cavalry, having lost their
impetus, and with their horses blown, would be nearly helpless and
easily repulsed.

3. At a distance, the most effective fire on cavalry is with
_howitzers_, on account of the terror and confusion caused among the
horses by the bursting of the shells.

On the cavalry's flanks, when within four hundred or five hundred
yards, the fire with grape would be most effective.

4. The _last discharge_ should be of canister alone, and made by all the
pieces at once, when the battery should be swiftly withdrawn.

5. If the cavalry succeed in reaching the pieces before their
withdrawal, the gunners may find temporary refuge _under the carriages_.


F. AGAINST ARTILLERY.

1. As guns in the field should generally play on troops instead of
batteries, there should be a _reserve of horse artillery_ to take the
enemy's batteries in flank, in case of need, as well as for other
purposes.

2. Though the ordinary use of artillery is against infantry and cavalry
only, special circumstances may render it expedient that a certain
portion of it should _respond to the enemy's batteries_. In this case,
not over one-third should be used for that purpose.

3. When we have _guns in abundance_, it might be sometimes advisable, by
using several batteries at once, to silence the enemy's guns, before
beginning to play on his troops.

4. Artillery properly plays on the enemy's _guns_--

(1.) At the moment of their coming into action, for then they are so
exposed that our fire will be peculiarly effective, and perhaps to such
a degree as to prevent their opening on us.

(2.) When our troops move forward to attack, in order to draw away from
them the fire of the enemy's batteries, or, at least, to render it
unsteady, inaccurate, and ineffective; and

(3.) Generally, when his guns are causing us very great damage.

5. _Against guns_, solid shot or shells only should be used, since they
alone are capable of inflicting any serious injury on either guns or
their carriages: solid shot, by their great weight and momentum; shells,
by their bursting.

But within three hundred or four hundred yards, grape and canister would
soon destroy the gunners and the horses.

6. Our fire on a hostile battery would not only be very effective when
it is coming into action, but at all other times _when its flanks are
exposed_; as in limbering up to move off, or in a flank march. On these
occasions we should use grape, if near enough; otherwise, spherical case
would be generally the best.

7. When possible to avoid it, _a field battery should not be opposed to
a battery of position_, or, generally, a battery of light guns to one
of heavy guns. For even when the numbers of pieces on the two sides are
equal, the enemy's superiority in range and in weight of metal would
give him such advantage in the duel that our own battery would soon be
destroyed or silenced.


VI.--Its Fire.

1. It is important not to commence the fire till our guns are in _sure
range_--

(1.) Because a harmless fire serves but to embolden the enemy and
discourage our own troops.

(2.) Because artillery ammunition should never be wasted. The fate of a
battle will sometimes depend on there being a sufficient supply of it at
a particular moment.

2. The usual maximum distances at which smooth-bore field guns may open
fire _with any considerable effect_, are--

   For 12-pounders     1100 yards.
   For 6    "           750   "

What these distances are in respect to rifled guns, it does not appear
to be yet definitively settled. The extreme range of the new rifled
six-pounders is said to be three thousand yards; of the twelve-pounders,
four thousand five hundred yards.

3. Guns are usually fired _by order_, and not by salvos, or volleys; and
never as soon as loaded, unless delay be dangerous. Artillery fire is
formidable only in proportion to its accuracy; and this is attainable
only by a cool and calculated aim.

4. Artillery fire should never cease _through the whole line at once_.
This would have a discouraging effect on our own troops, and an
inspiriting one on the enemy's. Especially must this not be done when we
are about to execute any manoeuvre; for it would be sure to call the
enemy's attention to it.

Therefore, if a particular battery has to change its position, it must
not cease the fire of all its pieces at once; for, besides its
disquieting effect on our troops, it would notify the enemy of the
movement.

5. In _covering an attack_, our guns should keep up their fire till the
moment it would begin to endanger our advancing columns.

6. By a _ricochet_ fire, artillery is said to increase its effect, from
one-fourth to one-half. It is especially effective in enfilading a line
of troops, a battery, or the face of a work taken in flank.

Ricochet shots have also great moral effect.

7. When used against _breastworks of rails or logs of wood_, guns should
be fired with moderate or shattering charges; so as more surely to
demolish them, and, at the same time, to increase the destructive effect
of the fire by scattering the splinters.

In view of the frequent necessity of battering such defences, and of
using a ricochet fire, which also requires small charges of powder, it
would be an improvement in our artillery service to make a certain
proportion of the ammunition in each gun limber to consist of cartridges
of half the usual size.

8. In _bombarding a village_ during a battle, if our object be to set
fire to and destroy it, this will be best accomplished with shells. If
we wish merely to drive the enemy from it, solid shot from heavy
calibres will be necessary, which will more surely reach and destroy his
troops, wherever they may show themselves.

9. The _moral effect_, both of solid shot and of shells, is much greater
than that of grape or other case-shot, from their more fearful effects
on the human frame, and from the great number of men that a single ball
or shell will kill or fatally wound. One twelve-pound solid shot has
been known to kill forty-two men, who happened to be exactly in its
range.

10. _Ball and shell_ should be used--

(1.) When the enemy is at a distance.
(2.) When he is in mass.
(3.) When he is in several lines.
(4.) When his line may be enfiladed.

11. In _silencing a battery_, our fire should be concentrated on one
piece at a time, while some of our guns throw spherical case, from a
raking position, if possible, on the gunners.

12. Though grape has a much less range than ball, yet _within four
hundred yards_, on account of its scattering, its effect is superior to
it.

The fire of guns double shotted with ball and a stand of grape, is
fearfully destructive when used at a short distance to repel a charge.

13. It is artillerymen's point of honor _not to abandon their pieces
till the last extremity_. They should always remember that when the
enemy is closing on them, the last discharge will be the most
destructive of all, and may suffice to repulse the attack and turn the
tide of battle.

In our attack on Quebec, in our War of Independence, on the near
approach of our assaulting column, the British gunners fled from their
pieces; but the one who fled last, before leaving, discharged his gun,
which was loaded with grape. The discharge killed and wounded several of
our men; among them the brave General Montgomery, who was leading the
column in person. The effect was decisive. The assailants fell back,
panic-struck at the loss of their commander; and our attack failed.

14. To prevent our own captured pieces from being turned on us by the
enemy, it is the artillerymen's last duty, when it has become evident
that the guns cannot be saved, to _spike_ them. The operation requiring
but a few moments, it can rarely be omitted without disgrace.


VII.--Its Supports.

1. Artillery must always be protected from the _mêlée_, in which it is
helpless whether against infantry or cavalry; and should therefore have
a strong _support_.

2. A portion, at least, of every artillery support, should consist of
_sharpshooters_, whose fire will be the most effective in driving off
skirmishers sent forward to threaten or attack the guns, or to pick off
the gunners.

3. Batteries must be secured _on both flanks_, and their supports will
be posted with that view; on one or on both flanks, according to
circumstances, and more or less retired.

4. A support should never be directly _in rear_ of the battery, where it
would be in danger, not only of receiving the shots aimed at the
battery, but also of killing the gunners belonging to it, as has
repeatedly happened during the late war.

5. A battery and its support owe each other _mutual protection_.
Therefore, when an infantry support, after holding the enemy in check,
to enable the battery to limber up and retire, is obliged, in its turn,
to retreat, the battery should take such a position as will enable it to
cover the retreat by its fire.

6. A battery consisting of any considerable number of pieces may be
able, sometimes, to _dispense with a support_.

During the battle of Uclès, in Spain, in 1809, the French artillery,
under General Senarmont, had been left behind, owing to the badness of
the roads. The Spaniards came down upon it in large force. On their
approach, the guns were formed in square, and, by their fire on every
side, defended themselves successfully, and finally repulsed the enemy.

So, at Leipsic, in 1813, when the grand battery of the Guard, which had
been left temporarily without a support, was charged by the Russian
hussars and Cossacks, Drouot, its commander, rapidly drew back its
flanks till they nearly met; and the cavalry were soon repulsed by its
fire.

7. At the battle of Hanau, in 1813, Drouot's eighty guns were charged by
the Allied cavalry. Having no supports, he placed his gunners in front
of them with their carbines. This checked the cavalry, who were then
covered with grape, which drove them back to their lines.

Ought not our gunners also to have _carbines slung on their backs_ for
such emergencies? Against infantry, our guns would often need no other
support. The carbines could be used to reply to the enemy's skirmishers;
and the example just cited shows that, thus equipped, artillerymen may
sometimes successfully defend their pieces even against cavalry.

IX.--GENERAL REMARKS.


I.--Its Formations.

1. The _formations_ of cavalry for battle are either--

(1.) In deployed lines.
(2.) Lines of regiments, in columns of attack doubled on the centre.
(3.) A mixed formation of lines and columns.
(4.) Echelons of lines or columns; or--
(5.) Deep columns.

2. _Deployed lines_ are not objectionable in principle. They are often
not advisable; but are sometimes necessary.

But long, continuous lines should always be avoided; being unfavorable
to rapid manoeuvring, which cavalry is constantly called upon to
execute in the field.

3. Cavalry has, in its horses, an unreasoning element, which is not
controllable, like men; and is therefore much more easily thrown into
disorder than infantry. For this reason, when deployed, it should always
be _in two lines_; the second behind the first; the first line deployed,
and the second in columns of squadrons by platoons. There should be also
a reserve at a few hundred paces behind the second line.

The second line should be near enough to the first to be able to support
it, if checked; but not so near as to partake in its disorder, if
repulsed.

4. Cavalry should be always _in column_ when expecting to manoeuvre,
or to be called on to make any rapid movement; this being the formation
best adapted for celerity.

5. Cavalry deploys _in lines_--

(1.) When preparing for a charge in line.

(2.) When preparing for any attack requiring the utmost possible width
of front; as where the enemy is to be suddenly surrounded.

(3.) When it becomes necessary in order to prevent our troops from being
outflanked by the enemy's.

(4.) When exposed to continued artillery fire, which is much less
destructive on a line than on a column.

6. Cavalry should always present _a front at least equal to the
enemy's_; otherwise, its flank, which is cavalry's weak point, will be
exposed to attack. When inferior in numbers, we may extend our line by
leaving intervals, more or less wide, between its different corps. Any
hostile squadrons that may attempt to pass through these intervals to
take the line in rear, could be taken care of by the second line.

7. The best formation in respect to _mobility_ is a line of regiments in
columns by squadrons, doubled on the centre; corresponding to infantry
double columns.

8. The _mixed formation_ of lines and columns is more manageable than
simple lines. Which of these two is preferable depends upon the ground,
and upon all the other circumstances of the case.

9. The order _in echelons_ is as good in attack as in retreat; since the
echelons mutually support each other.

10. Decidedly the most objectionable of all cavalry formations is that
in _deep columns_:

(1.) From the almost entire loss which it involves of its sabres, which
are cavalry's peculiar and most effective weapon.

(2.) From the long flanks which it exposes to attack.

11. The formation in _one rank_, instead of two, has been introduced by
the new Cavalry Tactics, though it has been as yet but partially adopted
in the field.

This innovation has two advantages. It doubles the number of sabres to
be used against the enemy; and it enables the cavalry to cover double
the ground; thus doubling, also, its power to outflank, which is a
valuable advantage, especially when opposed to cavalry.

Its disadvantage is, that it must, more or less seriously, impair the
solidity and vigor of the cavalry charge proper; in which a whole line,
with "boot to boot" compactness, comes at once to the shock, like some
terrific mechanical engine; and in which the riders in the front rank
are compelled to dash on with full speed to the last; knowing that if
they slacken rein, even for a moment, they would be ridden over by the
rear-rank men one yard behind them. From there being no rear-rank to
fill up the gaps caused, during the charge, by the enemy's missiles, or
by casualties occasioned by obstacles of the ground, the charging line
must generally arrive on the enemy broken and disunited, or as foragers.
The moral effect of such a charge on our own men will be unfavorable, as
they will not realize the certainty of mutual support at the critical
moment; and its moral effect on the enemy must be decidedly inferior to
that produced by a charge that is at once swift, solid, and compact.

But the force of this objection is somewhat weakened, by the
consideration that the compact charge of "cavalry of the line" must
hereafter be comparatively rare, in consequence of the introduction of
rifled artillery and infantry weapons, with their greatly increased
accuracy and range; which ought to cause such slaughter in a line or
column of charging cavalry, that, if it arrive at all to the shock, it
would generally be only in scattered groups.

12. In advancing over wooded, or other obstructed ground, it may be
necessary to break the line into _company columns of fours_, as in the
infantry manoeuvre of advancing by the flanks of companies.

As the cavalry column of fours corresponds to the march of infantry by
the flank, the use of this formation in action is open to the same
objections that have been already pointed out as applying to flank
marches by infantry.


II.--Its Strong and its Weak Points.

1. The value of cavalry on the battle-field consists chiefly in its
velocity and mobility. Its strength is in the _sabre-point and spurs_.

2. Its charge is accompanied with a _powerful moral effect_, especially
upon inexperienced troops. But,

3. Cavalry has but _little solidity_, and cannot defend a position
against good infantry. For, if it remain passive on the ground it is to
hold, the infantry will soon destroy it by its fire, to which it cannot,
with any effect, reply; and if it attack at close quarters, the
infantry, by means of its defensive formations, will be able, at least,
to hold its ground, and probably repulse its charges by a reserved
fire. So that the cavalry will finally have no alternative but to
retire.

4. It is exposed and helpless _during a change of formation_; like
artillery limbering up, or coming into action.

5. _On its flanks_, it is the weakest of all arms. A single squadron
attacking it suddenly in flank, will break and rout cavalry of ten times
its number.

At the battle of the Pyramids, Napoleon kept a few squadrons in rear of
either flank, which, on his line being charged by a formidable body of
Mamelukes, vastly superior to his own cavalry in numbers, horses, and
equipments, nevertheless suddenly fell on their flanks and destroyed
them.

6. Cavalry is never so weak as directly _after a successful charge_;
being then exhausted, and in more or less disorder.


III.--How Posted.

1. A part of our cavalry must be so posted as to _secure our flanks_;
remaining in column behind the wings, till the enemy's movements require
its deployment.

If one wing is covered by natural obstacles, give the cavalry to the
uncovered wing; posting it in rear of the flank battalion of the second
line.

2. When cavalry is posted on the flanks, it should _not usually be on
the first line of infantry_. If it is to be used for attack, it is
better to keep it retired from view till the last moment, in order to
strengthen its attack by the powerful moral effect of a surprise. And,
used defensively, it will be best posted on the flanks of the second
line; since, in advancing to charge, it must have a clear space in its
front of at least two hundred or three hundred yards, to enable it to
act with freedom and vigor.

3. But if a position can be found for cavalry in front, where it would
not be too much exposed, this may sometimes enable it to exercise an
important moral effect, by _threatening the flank_ of such of the
enemy's troops as may be sent forward to attack.

At the battle of Leipsic, in 1813, the Wurtemburg cavalry was launched
against Blucher's Prussian cavalry. But, seeing the Prussians drawn up
not only in front, but opposite their flank, they lost confidence,
charged feebly, and too late. They were consequently repulsed and
driven back on the Marine Battalion, which they threw into confusion.

So, at the battle of Prairie Grove, in December, 1862, the First Iowa
Cavalry, which was held in reserve, by its mere presence, caused every
attempt of the rebels' flanking regiments to be abandoned.

4. In order not to impede the manoeuvres of the infantry, cavalry
should not _fill intervals_ in the lines, or be placed between the
lines.

It is dangerous when the ground is such as to require the cavalry in the
centre of the first line; for, if it is beaten, a gap is left through
which the enemy may penetrate. At the battle of Blenheim, in 1704,
Marlborough owed his victory, in great measure, to the Allies' forcing
back the cavalry forming the centre of the French army; thus turning the
whole of its right wing, and compelling the infantry posted at Blenheim
to surrender.

5. Yet cavalry should always be near enough to the infantry to take
immediate part in the combat; and although it should not be posted in
the intervals between infantry corps, it may _debouch through them_, in
order to attack more promptly.

At the battle of Friedland, the Russian cavalry charged a French
infantry division. Latour Maubourg's dragoons and the Dutch cuirassiers,
riding through the battalion intervals, charged the Russians in turn,
and drove them back on their infantry, throwing many of them into the
river.

6. When _both wings are uncovered_, the best place for the cavalry will
usually be in rear of the centre of the second line; whence it can be
sent in the shortest time to either wing.

7. Cavalry should not be _scattered over the field_ in small
detachments, but be kept massed at one or more suitable points; as
behind the centre, or behind one wing, or both wings. A small cavalry
force should be kept entire; or it will have very little chance of
effecting any thing whatever.

Cavalry of the line, to produce its decisive effects, must be used in
heavy masses. In the beginning of the Napoleonic wars, the French
cavalry was distributed among the divisions. Napoleon's subsequent
experience led him to give it more concentration, by uniting in one mass
all the cavalry belonging to each army corps; and, finally, these masses
were again concentrated into independent cavalry corps; leaving to each
army corps only cavalry enough to guard it.

8. For tactical operations in the field, cavalry insufficient in number
is _scarcely better than none at all_, as it can never show itself in
presence of the enemy's cavalry, which would immediately outflank and
destroy it, and must keep close behind its infantry.

At the opening of Napoleon's campaign of 1813, he had but very little
cavalry to oppose to the overwhelming masses of this arm possessed by
the Allies. In consequence of this, he could make no use of it whatever;
and the tactical results of the battles of Lutzen and Bautzen were far
inferior to those habitually obtained in his former victories, and were
purchased with much greater loss.

9. Small bodies of cavalry threatened by the enemy's cavalry in greatly
superior force, may sometimes be saved by taking refuge _in an infantry
square_, as practised by Napoleon at the battle of the Pyramids.

10. Cavalry should _remain masked_ as long as possible; for it produces
most effect when its position and movements are hidden, so that a strong
force may suddenly be brought upon a weak point.

For this reason, a flat, open country is less favorable for this arm
than plains with undulations, hills with gentle slopes, woods,
villages, and farms; all these being so many facilities for screening
cavalry from view.

11. Cavalry should never be brought to the front, _except to engage_. It
is unfortunate when the ground is such as to prevent this; for cavalry,
compelled to remain inactive under fire, is in great danger of becoming
demoralized.

12. As to the _ground_:

(1.) Cavalry must not rest its flank on a wood, a village, or other
cover for an enemy, till it has been occupied by our own troops. If
compelled to do so, it should send out patrols to reconnoitre and
observe. Its position is no longer tenable from the moment the enemy
appears within striking distance on its flank.

(2.) It must not be posted on the very ground it is to defend, but in
rear of it; as it acts effectively only by its charge.

Attacking cavalry must have favorable ground in front; defending
cavalry, in rear. An obstacle in either case may be fatal.


IV.--Its Supports.

1. The flanks of cavalry lines or columns are always exposed. They
should, therefore, be protected by _supports_ of light cavalry, which
can act promptly and swiftly. When behind a line, these supports should
be usually in open column, so as to be able to wheel, without a moment's
delay, into line.

2. The _most effectual_ mode of protecting the flank of a line or column
of cavalry is by means of squadrons in rear, formed in echelons
extending outwards; as this exposes the enemy's cavalry that may attempt
to charge the main body in flank to be immediately charged in flank
themselves; which would be destruction. For this purpose, irregular
cavalry may be as effective as any other.

3. This cavalry support or reserve behind the flanks may sometimes play
_an important offensive_ part. The enemy's first line, the instant after
either making or receiving a charge, is always in greater or less
disorder; and a vigorous charge then made on it in flank by our own
flank reserve, would have a decisive effect.

4. Cavalry should never engage without a support or _reserve in rear_,
not only to guard its flanks, but also to support it when disorganized
by a successful charge.

5. So, when engaged in _skirmishing order_, being then very much
exposed, it must always be protected, like infantry skirmishers, by
supports in close order.

6. It has been already seen that, although cavalry may carry a position,
it cannot hold it, if attacked by infantry. When used for such a
purpose, therefore, it should always be accompanied by _an infantry
support_.

The French cavalry succeeded in carrying the plateau of Quatre Bras;
but, having no infantry with it to reply to the terrible fire of the
Allied infantry from the surrounding houses, it was compelled to retire,
and yield it again to the enemy.

According to Wellington, Napoleon frequently used his cavalry in seizing
positions, which were then immediately occupied by infantry or
artillery.


V.--How Used.

1. Cavalry generally manoeuvres _at a trot_. At a gallop, disorder is
apt to take place, and exhaustion of strength that will be needed in the
charge.

2. The ordinary use of cavalry is to follow up infantry attacks and
complete their success. It should never be sent _against fresh
infantry_; and should generally, therefore, be reserved until towards
the last of the action.

Napoleon, who, by concentrating his cavalry into considerable masses,
had enabled himself to use it on the battle-field as a principal arm,
sometimes produced great effects by heavy cavalry charges at the very
beginning of the action.

But, though Napoleon's splendidly trained heavy cavalry might sometimes
break a well-disciplined infantry without any preparatory artillery
fire, it would be dangerous to attempt this with cavalry inferior to it
in solidity; and the new rifled weapons would seem to render the cavalry
charges of his day no longer practicable.

3. Cavalry _may_ be hurled against the enemy's infantry--

(1.) When it has been a long time engaged, and therefore exhausted.

(2.) When it has been shattered by artillery.

And _always should_ be--

(1.) When it is manoeuvring.

(2.) When the attack would be a surprise.

(3.) When its ranks begin to waver, or when it manifests any unequivocal
symptom of hesitation or intimidation.

In the three latter cases, success will usually be certain; in the two
former ones, quite probable: but, in most other cases, a cavalry charge
will succeed, perhaps, only one time in ten.

4. The chief duties of cavalry in a _defensive_ battle are--

(1.) To watch the enemy's cavalry, to prevent its surprising our
infantry.

(2.) To guard our troops from being outflanked.

(3.) To defend our infantry and artillery while manoeuvring.

(4.) To be ready to charge the enemy the instant his attack on our
troops is repulsed.

5. _Used offensively_, it must promptly attack--

(1.) The enemy's flanks, if uncovered.

(2.) His infantry, when, from any cause, its attack would probably
succeed.

(3.) All detachments thrown forward without support.

6. When cavalry has routed cavalry, the victorious squadrons should at
once charge in flank _the infantry protected by the cavalry just
beaten_. The great Condé, when only twenty-two years of age, by this
means, won the victory of Rocroi.

7. Deployed as skirmishers, by their noise, dust, and smoke, cavalry may
furnish a good _screen_ for our movements.

8. Cavalry skirmishers _scout their corps_, to prevent the enemy
reconnoitring it too closely.

9. When a cavalry rear-guard has to defend, temporarily, a defile, a
bridge, or a barricade, a part should _dismount_, and use their carbines
till the rest are safe.

So, a cavalry vanguard, by its fire, dismounted, may prevent the enemy
from destroying a bridge.

In these, and in similar cases, the cavalrymen should habitually
dismount, in order to render their fire effective; acting and
manoeuvring as skirmishers.


VI.--How it Fights.

1. The success of cavalry in battle depends on the _impetuosity of its
charge_, and its _use of the sabre_. When deployed as skirmishers,
mounted or dismounted, its proper weapon is the carbine or pistol; and
in individual combats, these weapons may occasionally be very useful.
But when acting as cavalry proper, in any compact formation, it must
rely on the sabre. The aim with a pistol or carbine in the hands of a
mounted man is so unsteady, that the fire of a line of cavalry is
generally ineffective; and there are few occasions where it should be
resorted to. When cavalry has learned to realize that these are not its
true arms, and that it is never really formidable but when it closes
with the enemy at full speed and with uplifted sabre, it has acquired
the most important element of its efficiency.

2. Cavalry should, therefore, not fight _in columns_, as most of its
sabres would thereby become useless. But if a facing about to retreat is
feared, an attack in column would prevent it. It is said, also, that a
column is more imposing than a line. If so, it might have a greater
moral effect on the enemy.

3. When cavalry are deployed as skirmishers, as a curtain to hide our
movements, they should be _in considerable number_, with small
intervals, and should make as much noise, and smoke, and dust as
possible. When the charge is sounded, the skirmishers wait and fall in
with the rest.

4. The great rule in cavalry combats is to _cover our own flanks_, and
_gain the enemy's_; for these are his and our weakest points.

5. When the enemy's cavalry is already in full charge on our infantry,
it is too late for our cavalry to charge it with much prospect of
success. In such a case, it would be better to defer our own charge till
the moment that the enemy's _is completed_; for our success then would
be certain.

6. Cavalry attacks cavalry _in line_, in order to have the more sabres,
and, if possible, to outflank the enemy.

7. If we can manoeuvre so as to attack the enemy's cavalry _in flank_,
our success will be certain.

Military history affords hundreds of instances in proof of this
proposition. At one of the battles in Spain, for example, in 1809,
fifteen hundred French horse, by charging four thousand Spanish cavalry
in flank, completely cut it in pieces.

8. Cavalry _never waits in position_ to be charged by cavalry. Its only
safety is in meeting the charge with a violent gallop; it would
otherwise be sure to be overthrown.

When hostile cavalries thus meet each other, there is usually but small
loss on either side. A certain number of troopers are usually
dismounted; but the colliding masses somehow ride through each other,
allowing but little time for the exchange of points and cuts.

Thus cavalry can defend itself against cavalry only by attacking; which
it must do even when inferior to the enemy in number.

9. To attack artillery, cavalry should be in _three detachments_;
one-fourth to seize the guns; one-half to charge the supports; and the
other fourth as a reserve.

The first party attacks in dispersed order, as foragers, trying to gain
the flanks of the battery. The second party should manoeuvre to gain
the flanks of the supports.

10. Where a cavalry attack can be masked, so as to operate _as a
surprise_, a battery may be taken by charging it in front. The
formidable Spanish battery in the Pass of Somosierra, was finally
carried by a dash of Napoleon's Polish Lancers upon it, suddenly
profiting of a temporary fog or mist. But, in ordinary cases, when
cavalry has to charge a battery in front, its fire should be drawn by
our own guns or infantry, immediately before the charge begins.

11. In an attack on an _intrenchment_, the office of cavalry can rarely
be any thing else than to repulse sorties from the work, and to cut off
the enemy's retreat from it.


VII.--Its Charge.

1. As cavalry acts effectively on the field of battle only by its
charge, good cavalry of the line can be formed in no other way than by
being _exercised in this_, its special and peculiar function.

On taking command of the Army of Italy in 1796, Bonaparte found the
French cavalry to be entirely worthless. They had never been accustomed
to charge, and he had the greatest difficulty in making them engage.
Seeing the great importance of this arm, he determined to make good
cavalry of them by compelling them to fight. So, in his attack on
Borghetto, he sent his cavalry forward, with his grenadiers on their
flanks, and his artillery close behind them. Thus enclosed, and led on
by Murat to the charge, they attacked and routed that famous Austrian
cavalry whose superiority they had so much dreaded. This was the first
step in the formation of the splendid French cavalry to which Napoleon
afterwards owed so many of his victories. And, at the battle of
Hochstedt, on the Danube, in 1801, its superiority over the Austrian
cavalry was, at last, completely established.

2. Cavalry _charges_--

(1.) In line; but this only on even ground, and at short distances;

(2.) In column; and

(3.) As foragers, or in dispersed order. But this kind of charge is
exceptional. It can rarely be used with safety against any but an
uncivilized or an undisciplined foe.

3. A charge in _one long continuous line_ should never be attempted.
Such a charge will be usually indecisive, as it cannot be made with the
necessary _ensemble_ or unity. The success of a charge in line depends
on the preservation of a well-regulated speed and of a perfect
alignment; by means of which the whole line reaches the enemy at once.
At the charging gait, this is rarely attainable; so that the charge in
line, except at short distances, and over very even ground, usually
degenerates into a charge by groups, or individual troopers, arriving
successively. The most dashing riders, or those mounted on the swiftest
horses, will naturally arrive first, and be overpowered by numbers.

4. A charge _in deep column_ is also objectionable; its long flank
exposing it too much to artillery fire and to the enemy's cavalry.

But when cavalry is surprised, it must charge at once, in whatever order
it happens to be, rather than hesitate or attempt to manoeuvre, for
this would expose it to destruction.

5. A prompt and unhesitating obedience to the command to charge, without
regard to the circumstances under which it is given, may sometimes lead
to results _unexpected even to the charging troops themselves_.

One instance of this was related to me by an old officer of Napoleon's
favorite Fifth Cuirassiers. The regiment was on the left of the line of
battle. Directly in front of it was an extensive marsh; beyond which
rose an eminence, abrupt in front, but sloping gently towards the rear,
the crest of which was crowned by formidable Austrian batteries. For two
hours the cuirassiers had been standing in line, listening to the roar
of battle on the right, and eagerly expecting a summons to go
_somewhere_ to engage the enemy. The very horses were neighing and
pawing the ground, in their impatience to be off. Just then galloped up
one of the Emperor's aids, saying, "Colonel, the Emperor desires you to
charge directly on the enemy's batteries opposite your position." The
brave colonel, who was one of Napoleon's personal favorites, though
chafing at the prolonged inaction of his command, pointed to the marsh,
and requested the officer to inform the Emperor of the obstacle in his
front, with the existence of which his majesty, he said, was probably
unacquainted. In a few minutes the officer came riding furiously back
with a message to the colonel, that "if he did not immediately charge,
the Emperor would come and lead the regiment himself." Stung by this
reproof, the colonel plunged his spurs into his horse's flanks, and
giving the command "Forward," led his regiment, at full gallop, directly
through the marsh upon the point that had been indicated.

The charge itself was, of course, a failure. The regiment finally
struggled its way through the marsh to the opposite side, but leaving
behind it a large number of gallant officers and men, who had sunk to
rise no more; my informant being of the number who escaped.

But the result of this demonstration was most decisive. Seeing that the
height on which the Austrians had planted their heavy batteries, and
which commanded the entire ground, was the key of the battle, Napoleon
had determined to wrest it from them, together with the batteries which
crowned it. Accordingly, the evening before, he had dispatched a body of
light infantry by a very circuitous route, to turn the position and
attack the batteries in rear. He had accurately calculated the time the
detachment would require to reach its destination; and when the moment
arrived at which it should be ready to commence its attack, he ordered
the cuirassiers to charge directly upon the position in front. The
Austrian artillery, suddenly attacked in rear, and, at the same time,
threatened with a cavalry charge in front, where it had deemed itself
perfectly secure, tried to change the position of its pieces, so as to
get a fire on its assailants from both directions. But it was too late;
the temporary confusion into which it was thrown enabled the French
infantry to carry all before it, and the height was won, with all its
batteries.

So, at Waterloo, Sir Hussey Vivian's brigade of Light Cavalry, which was
marching in column by half squadrons, left in front, had begun to form
up into line on the leading half squadron, when an order arrived from
Wellington to charge. Instantly the charge was made, and, of course, in
echelons of half squadrons, extending to the right. The effect of this
was that a body of French cavalry on its right, then attacking the
British line, was suddenly taken in flank and completely routed.

6. A charge in deep column may sometimes be made necessary by _the
nature of the ground_, which, at the same time, protects its long
flanks: as where, in our pursuit of the rebels after the battle of
Nashville, in 1864, the Fourth United States Cavalry, approaching them
over a narrow turnpike, made a vigorous charge in column of fours, which
broke their centre, and, with the help of infantry skirmishers on the
flanks, drove them from the ground.

7. When the ground is rugged, in order to lessen the number of falls,
the rear-rank, in the charge, should _open out six paces_, closing up
again at the last moment.

8. Cavalry advances to charge at a _trot_, or at a _gallop_. A fast trot
is better than a gallop, as alignments are not easily kept at great
speed. Experience has shown that the best distance from the enemy to
begin the gallop, is about two hundred and sixty yards; thence steadily
increasing to the maximum of speed. This gradual increase of speed is
very important, to prevent the horses from being completely blown on
reaching the enemy.

9. Cavalry should not charge by _a wood_, till it has been carried by
our own infantry, if it can possibly be avoided.

At the battle of Kollin, in 1756, Frederick's cavalry, pursuing the
Austrians, was taken in flank by some Austrian infantry posted in a
wood, and made to retire with great loss.

10. When cavalry is required to charge over unknown ground, it should be
preceded by a few men thrown out to the front as skirmishers, in order
to _scout the ground_ to be passed over. The neglect of this precaution
has sometimes led to great disaster.

At Talavera, two cavalry regiments, the First German Hussars and the
Twenty-third Light Dragoons, were ordered to charge the head of some
French infantry columns. When near the top of their speed they came
suddenly upon a deep ravine, with steep sides. Colonel Arentschild
commanding the Hussars, who was in front, at once reined up, and halted
his regiment, saying: "I vill not kill my young mensch!" But the other
regiment, commanded by Colonel Seymour, which was on its left, not
seeing the obstacle in time, plunged down it, men and horses rolling
over on each other in frightful confusion. Of the survivors, who
arrived on the other side by twos and threes, many were killed or
taken; and only one-half of the regiment ever returned.

So, at the battle of Courtrai, in 1302, from the French cavalry's
omitting to scout the ground they charged over, the Flemings won a great
victory. All the _élite_ of the French nobility and chivalry was
destroyed, and gold spurs were collected by bushels on the field. It was
the French Cannæ. The Flemings were drawn up behind a canal, flowing
between high banks, and hidden from view. The French rushing on at full
gallop, all the leading ranks were plunged into the canal. The entire
cavalry was thereby checked and thrown into irretrievable disorder,
which extended to the infantry, in their rear. The Flemings, profiting
by their confusion, crossed the canal at two points simultaneously,
attacked them in flank, and completed their rout.

So, at the battle of Leipsic, in 1813, Murat, in his great cavalry
charge on the Allied centre, had captured twenty-six guns, and was
carrying all before him, when he pushed on to the village of Gulden
Gossa, where the ground had not been reconnoitred, and could not be
distinctly seen from a distance. Here the French found their career
suddenly checked by a great hollow, full of buildings, pools of water,
and clusters of trees; while the Allied infantry, from behind the
various covers afforded by the ground, opened upon them a destructive
fire. Being then suddenly charged in flank by the Russian cavalry, they
were driven back with heavy loss; the Allies recapturing twenty of the
twenty-six guns they had lost.

The troopers employed to scout the ground before a charge would not be
in much danger from the enemy, who would hardly fire on a horseman or
two, especially when expecting a charge.

11. Cavalry must never pursue, unless its supports are _close at hand_.

In pursuing, it must be circumspect, and not go too far. Union and order
are indispensable; for, without them, a slight resistance may suffice to
cause a repulse.


VIII.--Its Attack on Infantry.

First, as to its ATTACK GENERALLY.
Secondly, its attack ON SQUARES.


A. GENERALLY.

1. Cavalry must avoid _distant engagements_ with infantry; in which the
latter must always have the advantage.

2. The slightest cavalry charge on the _flank_ of infantry will rout it.

3. As to a cavalry attack _in front_: If the infantry stand firm, the
chances are against its success. If the infantry cannot be attacked in
flank, the cavalry should therefore wait till it has been shattered by
artillery, or has become exhausted, or demoralized, or till it begins to
manoeuvre.

4. If the infantry be _in line_, or _in column_, cavalry should attack
it in flank; if _in square_, at one of its angles; if _in several
squares_, at one of its flank ones, so as to avoid a cross-fire from the
other squares. If a flank square be broken, the next one to it, being no
longer protected by the fire of any other square, may be attacked with
the same prospect of success; and so on successively.

5. But if the hostile infantry have _supporting cavalry_, we must not
charge in such a manner as to enable it to take us in flank.

6. To _test the infantry_ about to be attacked, cavalry may pass a few
hundred paces in its front, to threaten it, sending forward a few
horsemen to fire, gallop forward, and raise a dust. If the infantry,
instead of disregarding these movements, begin to fire, it will probably
be broken, on the cavalry's charging it at once and vigorously, whether
in column or in line. But otherwise, if the infantry reserve its fire,
and only sends out a few sharpshooters.

7. _Ascending slopes_, if not too steep, are not unfavorable to attacks
on infantry; for their shots, as experience shows, will then mostly fly
too high.

8. On a _descending slope_, cavalry charges down on infantry with
terrible effect; as it then arrives with an impetus which nothing can
stop.

At Waterloo, a column of French infantry was ascending a steep slope.
Suddenly the Scotch Greys cavalry regiment dashed down upon it from
above, rode over, and destroyed it.

B. ON SQUARES.

1. Infantry squares are usually charged in _open column_; the distance
between the subdivisions being a subdivision front and a few yards over;
in order that each subdivision may have time to break into the square,
or, if unsuccessful, to disengage itself and retire.

But the distances should never be so great as to allow the square to
reload after firing a volley at the next preceding subdivision.

2. The leading subdivision will usually _draw the fire_ of the square.
If this is delivered at very short range, say at twenty paces, it will
raise up a rampart of dead and wounded men and horses which will
probably suffice to check the following subdivisions, and so repulse the
charge. But an infantry square rarely reserves its fire so long; and if
the fire is delivered at any considerable distance, no such effect will
be produced.

3. A _good formation_ to attack a square is said to be a column of three
squadrons, with squadron front, at double distance; followed by a fourth
squadron, in column of divisions or platoons, to surround the square,
and make prisoners, if it is broken.

4. Before cavalry charges a square, it should be first shattered or
demoralized by _artillery fire_, when this is practicable. In the
absence of artillery, sharpshooting infantry skirmishers may, to a
certain extent, supply its place.

5. A square should be attacked at one of its angles, which are obviously
its weakest and most vulnerable points. But to cover a real attack on an
angle, cavalry sometimes makes a _false attack_ on the front of a
square.

6. When squares are formed checkerwise, cavalry must attack _a flank
square_, and not expose itself to a cross-fire by charging an interior
one.

7. Cavalry charging a square firing irregularly will usually break it.
But when the square reserves its fire, and pours in well-aimed volleys
at short range, the charge will rarely succeed. The cavalry should,
therefore, before charging, use every effort to _draw the fire_ of the
square, or of the fronts which threaten it. This is sometimes
accomplished by sending forward a few skirmishers to fire on the square.

8. When one square fires to assist another, the firing square should be
_instantly charged_, before it has time to reload.

9. To succeed, a cavalry charge should be made with a _desperate,
forlorn-hope recklessness_, and with reiterated attacks on one point. If
the fire has been delivered at very close range, though its effect has
probably been destructive, the smoke will momentarily shut out the line
of infantry from the horses' view, thus removing the chief obstacle to
their breaking through it. The survivors of the fire should therefore
rush desperately on.

If the French attacks on the British squares at Quatre Bras had been
made in this manner, instead of opening to the right and left, and
diverging to a flank at the moment of closing, they would probably have
succeeded.

But this sudden divergence is often the fault of the horses, which
instinctively recoil before a serried line of infantry, with bayonets at
the charge. Cavalry should, therefore, never be practised on the
drill-ground in charging a square, as the horses would thereby acquire
the habit of suddenly checking their course, or of diverging to a flank,
on arriving at the enemy. This would so strengthen their natural
instinct that they could never be got to break a square. Or, at least,
when this manoeuvre is practised for the purpose of instruction, the
horses used should never afterwards be taken into the field.

10. The cavalry most formidable to an infantry square are _Lancers_.
Their lances, which are from eleven to sixteen feet long, easily reach
and transfix the infantry soldier, while the sabres of the other cavalry
are too short to reach him over the horse's neck, and over the musket,
lengthened by the bayonet. But Lancers are usually no match against
other cavalry, who can parry and ripost before the lance can resume the
guard.

11. When cavalry has succeeded in completely breaking a body of
infantry, it may often inflict _fearful slaughter_ upon them.

At the battle of Rio Seco, in Spain, after Lasalle's twelve hundred
horse had broken the Spanish infantry, they galloped at will among
twenty-five thousand soldiers, some five thousand of whom they slew.


IX.--General Remarks.

1. Besides its uses on the field of battle, cavalry may render most
important service in completing the destruction of beaten corps, or
compelling their surrender, and so enable us to secure the great
strategic objects of the campaign. Thus, after the battle of Waterloo,
it was the Prussian cavalry that completed the dispersion of the French
army, and prevented it from rallying. And, but for Napoleon's ill
fortune in respect to Grouchy, in that battle, he would, to all
appearance, have succeeded in accomplishing his plan of campaign, which
was, to separate the English from the Prussians, beat them in detail,
and complete their destruction with his twenty thousand cavalry.

2. The battles of the late War of the Rebellion, the earlier ones, at
least, were mostly indecisive. One chief cause of this was, that neither
side had a sufficient force of true cavalry to enable it to complete a
victory, to turn a defeat into a rout, and drive the enemy effectually
from the field. The cavalry charges were generally such as mounted
infantry could have just as well made; charges in which the pistol and
carbine played the principal part, instead of the spur and sabre. It was
not until the fight at Brandy Station, in June, 1863, that sabres were
used, to any extent, at close quarters. Thus, neither of the contending
armies was able to break up and disperse, destroy, or capture its
enemy's infantry masses, in the manner practised in Napoleon's great
wars, not having, to any considerable extent, that description of force
called Cavalry of the Line, which alone is capable of effecting these
results by its solid and compact formations, its skilful, yet rapid
manoeuvring, and its crashing charges.

3. European cavalry of the line is divided into Heavy and Light. Heavy
cavalry is heavily armed; that is, their weapons are larger and heavier
than those of light cavalry, and to these weapons, carbines, in most of
the corps, are added. Some of the corps wear steel or brass cuirasses;
and the men and horses are of the largest size.

In Light cavalry, the only weapons are the sabre and pistol; and the men
and horses are light and active, rather than strong and large.

Lancers are considered a medium between Heavy and Light cavalry.

4. Great as may be the advantages of a large force of regular cavalry of
the line, there were serious objections to its being raised at the
opening of the late war.

(1.) The theatre of war presented nowhere any of those wide and level
plains so common in Europe, and on which cavalry masses are able to
produce such decisive effects in battle. On the contrary, the ground was
almost everywhere so rugged and mountainous, or else so densely wooded,
as to be extremely unfavorable to the movements of cavalry of this
description.

(2.) Since the introduction of the new rifled arms, exposing cavalry
masses to a deadly fire at far greater distances than ever before known,
a fire often reaching to the reserves, it seemed doubtful whether the
manoeuvring and charging in heavy, compact masses, which formerly
rendered cavalry of the line so formidable, would any longer be
practicable.

(3.) The comparative cost of this kind of force is so great, that, if it
had been raised and kept up on the scale required, the expense of this
war, enormous as it has been, would have been vastly augmented. Three
years are required for the thorough training and instruction of the men
and horses; so that it would not have been until the fourth year of the
war that we could begin, even, to reap the fruits of so enormous an
outlay.

5. But to carry on any war successfully, what is needed, and is, in
fact, indispensable, is an ample force of light cavalry, of a kind
requiring comparatively but little time and training to fit it for the
various and important duties devolving upon it in the field, and
therefore far less expensive than cavalry of the line; and having all
the discipline of this latter kind of force, though wanting its
perfection of manoeuvre. Every army, or considerable detachment, must
have enough of this kind of force with it to furnish what is requisite
for Outpost duty, Patrols offensive and defensive, Escorts to trains,
Foraging parties, Reconnoissances, and the various other purposes
necessarily incidental to operations in the field; and in marches, all
Advanced, Rear, and Flank guards should consist, in part, at least, of
cavalry. Finally, this description of force is needed for the
performance of those arduous, but most valuable, services often rendered
by the quasi-independent bodies called Partisan Corps; services usually
requiring great celerity of movement.

6. This kind of force being "the eyes and ears of an army," it often
contributes powerfully to the success of strategic operations.

In the campaign of 1813, Napoleon complained that, for want of light
cavalry, he could get no intelligence of the enemy's movements.

So, in the rebel campaign of 1863, culminating at Gettysburg, General
Lee attributed his ignorance of our position and movements, which led to
the failure of his operations, to his being destitute of this arm;
Stuart's cavalry, on which he depended for information, having got too
far away from him.

In Pope's campaign in 1862, the rebels, by their cavalry raid on
Catlett's Station, obtained possession of the commanding general's
correspondence, plans, and orders from Washington.

On the other hand, whilst keeping us informed of the enemy's movements,
an abundant light cavalry, active and well commanded, may be so used as
to constitute an impenetrable screen of our own movements from the
enemy, as effectual as would be a lofty and impassable mountain range.

Again, if we are greatly inferior to the enemy in cavalry, our own
cavalry will have to keep itself within our infantry lines; and the
consequence will be that the enemy will obtain control of the entire
country around us, and so deprive us of all the supplies it contains.

As, besides this, cavalry is absolutely necessary for the protection of
convoys, and, from its celerity of movement, is the kind of force best
fitted for guarding our communications, it is evident that the
subsistence of an army is dependent, to a great extent, upon this arm.

From what has been said in relation to the three arms, it is evident--

1. That ARTILLERY, within the range of its fire, is powerful in
preventing the enemy's approach to it; but, only to a limited extent,
can pursue and drive the enemy from his position; and that its function
is, therefore, mainly DEFENSIVE.

2. That CAVALRY, by the impetuosity of its charge, is peculiarly fit for
driving the enemy from his position; but, remaining in position itself,
has but feeble power to prevent the enemy's approaching it; and this,
only by its carbine and pistol fire, which is far from effective; and
that its function is, therefore, mainly OFFENSIVE.

3. That INFANTRY has great power, both in keeping the enemy at a
distance by its fire and in driving him from his position with the
bayonet; and that this arm is, therefore, both OFFENSIVE and DEFENSIVE.

4. That although artillery is mainly a defensive arm, it plays an
important offensive part in the powerful assistance it renders to
infantry, in shattering and disorganizing the enemy's masses; thereby
opening the way for our attacking columns.

5. That although cavalry is mainly an offensive arm, its defensive value
is also very great in the protection it affords, in various emergencies,
to the other arms, by its actual charge, or by its threatening position.

The special parts usually played in battle by the three arms
respectively, may be briefly stated thus:--

Artillery prepares the victory; Infantry achieves it; Cavalry completes
it, and secures its fruits.


THE END.
