A Treatise on the Tactical Use of the Three Arms Part 3

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 cuira.s.siers 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 cuira.s.siers 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 cuira.s.siers 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 pa.s.s 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 manuvre 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 pa.s.sed. 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 ma.s.s are considered preferable to hollow ones, on the supposition that though horses will recoil from a dense ma.s.s, 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 princ.i.p.al 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 cuira.s.siers 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 manuvring 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 ma.s.ses. Occasionally, in order to pa.s.s 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 pa.s.sed, 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 manuvring.

A regiment, or a brigade, in covered ground, whether the enemy be visible or not, should never change its position in battle, or manuvre, without the protection of a skirmis.h.i.+ng 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.
