Cavalry in Future Wars Part 9

When, after long marches, hours of fighting, and heavy losses, the exhausted victor bivouacs on the hard-won field, when the day is drawing to its close and the shadows are spreading far across the pastures, then the real work of the Cavalry begins; then, without drawing rein, the hors.e.m.e.n must press forward to intercept the enemy's retreat, attack him anywhere where he least expects it, and harry him to utter exhaustion and dispersal (see Book I., Chap. IV., 1.4); or it must, under the difficult conditions of a retreat at night, sacrifice itself in charges or in protracted fire action in every direction in which the pursuing Army can threaten danger to the retreating columns.

In such situations they must be prepared to hold suitable positions by the hour, without thought for their own retreat, without any knowledge of the general situation, and without any connection with the remainder of their forces. Threatened in flank and rear, and yet unshaken by the general collapse, by the flight and panic of their comrades, they must hold their own, relying on their own strength and self-reliance. These are the conditions which make the highest demands both on the material and moral excellence of the men, as well as on the indomitable energy and skill of the Cavalry Leader, and to few mortals is it given to prove equal to such contingencies; hence one must prepare one's self beforehand for such situations.

Primarily one must remember to give opportunities to both men and horses to feed, water, and rest even during the progress of the battle. One must endeavour, even while the fight is still raging, to become perfectly clear in one's own mind as to the possible lines of retreat, and the probable ulterior operations. One must try to impress upon one's memory the lie of the roads according to the map, and the important defiles and positions which might be favourable either to pursuit or retreat, in order to be able to act at the right moment, without loss of time or hesitation, in full cognizance of the circ.u.mstances of the case. _Nothing helps a decision more than a complete intellectual command of the situation._

Hence we see that the leading of Cavalry has been rendered immeasurably more difficult by a whole series of external considerations, as we have shown at the beginning of the chapter; that at every moment the highest demands will be made on the intellectual perception, the boldness and strength of character of the Leader, if on the battle-field of the future he is to handle the Arm with any prospect of success; and that the best Cavalry under modern circ.u.mstances must fail if their Leaders prove unequal to their task.

CHAPTER VI

TACTICAL CONDUCT OF DISMOUNTED ACTIONS

If, in the shock between mounted men, the genius of the Leader is the princ.i.p.al factor of success, nevertheless, the successful conduct of a dismounted combat and of all the variations this form of action may a.s.sume make almost equal demands upon his capacity. For the timely recognition of opportunities which can only be turned to account by recourse to fire power, the transition from one form of action to another, the skilful and systematic arrangement of a dismounted engagement, require such a complete command of the situation and such certainty of military judgment and decision of character that the combination will be almost as rarely found.

Moreover, in the power of holding the balance correctly between fire power and shock, and in the training for the former never to allow the troops to lose confidence in the latter, lies the real essence of the Cavalry spirit. This, whether it be in the working out of some great strategical design, or in joining hands with the other Arms to obtain by united fire action some common purpose, implies a balance of judgment and absence of prejudice of the rarest occurrence in normal natures.

The essential point which differentiates the action of Cavalry fighting on foot and of Infantry engaged in the same operation is the dependence of the former on their horses; and to arrange that under all circ.u.mstances of the combat the relation of the men on foot to their means of locomotion shall be suitably maintained is at once the most important and the most difficult task that falls to the lot of the Leader.

Primarily we have to decide whether we intend to fight with mobile or immobile horses,[13] and in every case the question arises how the conditions of the moment, whether in attack or defence, can best be dealt with.

[Footnote 13: When only three men in four dismount the horses are said to be 'mobile.' When the proportion is greater the horses become 'immobile.']

Turning first to the attack, as the most important form of action, consideration leads to the following conclusions: If the advance is made with 'mobile' detachments, then in case of success the horses can be led forward after us. It is then easy to remount, and continue the prosecution of our ultimate purpose. If, on the other hand, we fight with 'immobile' detachments, one cannot at once pursue one's successes with the same body of troops with which such success has been won.

Either the position which has been captured must be retained for some considerable period, or we must go back to where the horses were left, at the cost of considerable loss of time, and at the risk of intervening circ.u.mstances robbing us of further opportunity. Neither operation commends itself to the true Cavalry spirit.

On the whole, in attack the difficulty is best met by working with 'mobile' detachments, and the requisite number of rifles in the fighting line can then be provided by dismounting men from a larger number of units--Squadrons, Regiments, or Brigades.

From this principle one should only deviate when, owing to the proximity of the enemy's Cavalry or other circ.u.mstances, it is absolutely indispensable to keep a strong mounted reserve at hand, or when it can be foreseen that the number of rifles available, if the 'mobile' form is preferred, will obviously not be sufficient for the appointed task; for it must never be forgotten that the rapid attainment of fire superiority must be striven for under all circ.u.mstances.

If we turn to the consideration of the Defensive, our conclusion must be the exact converse.

The maintenance of fire superiority now becomes the primary objective, and since, in case of success, a general advance is precluded by the very conditions which compelled us to adopt the defensive role in the first instance, and further, owing to the conditions which surround a defensive combat generally, particularly the nature of the ground, it is usually practicable to bring the led horses closer up to the firing line, which remains stationary, and does not, as in the attack, constantly increase the distance between the two, it will be wiser to adopt the 'immobile' detachment as a fundamental proposition.

This gives us the further advantage of being able to retain a larger mounted reserve in hand for the initiation of a possible pursuit, and one should only depart from this principle when special circ.u.mstances make it appear desirable to advance rapidly after the decision of the fire fight, and the ground compels us to leave the led horses far behind the actual shooting line of the position.

Next to this question of 'mobile' or 'immobile' detachments, the Commander must decide how far away from the actual field of action he should dismount his men.

Fundamentally, the idea must hold good that one must ride up as close as possible to the line to be held or the position from whence the advance is to be made; and the limit to the mounted approach is only set by the necessity of retaining cover, at least from sight, for the led horses, and time enough, in the event of failure, to insure that the men can remount before fire can be brought upon them, even from a distance. The possibilities of becoming exposed to the indirect fire of Artillery must not be left out of consideration altogether in the solution of this question.

Hence, it can only happen very rarely, and then only under exceptionally favourable topographical conditions, that a suitable position for the led horses can be found in immediate proximity to the actual line of action.

We may, however, be less particular when, in fairly favourable country, it is advisable to engage, without the intention of courting a decision, our object being only to annoy the enemy by sudden fire, disappearing again as soon as he retaliates, or when one is reasonably certain of success, as against inferior or badly shaken troops.

But when such favourable conditions are not present, and a tactical repulse is always possible, then the place for the led horses can only be found so far to the rear that the enemy cannot take us under fire whilst in the act of remounting, and circ.u.mstances render it improbable that this emergency can arise before we have succeeded in breaking off fighting contact with the enemy.

The Commander, therefore, who decides to undertake a serious fire action must be perfectly clear in his own mind that by the act of dismounting he has severed his connection with his horses for a very considerable time; for if the enemy's resistance proves more obstinate than originally antic.i.p.ated, and it becomes clear that the original purpose is not to be attained with the available means, the expectation that after once engaging the enemy the fight can be broken off and the horses remounted will in most cases prove entirely illusory.

Since this operation of discontinuing a fire combat is most difficult to carry through, even for Infantry, the dangers are immensely greater for mounted men, owing to the added complication of their led horses.

Only the pa.s.sivity of the enemy, or unusually favourable topographical conditions, as in South Africa, can alter the general soundness of this conclusion; and it is entirely impracticable to escape these consequences by any attempt to lay down a limit and distance beyond which the fight is not to be prosecuted, in the hope that by so doing we can safely break off a combat once commenced. Generally it must be accepted, as laid down in Cavalry Regulations, Sections 362 and 364, that a fire action once accepted must be carried out to the end, unless the arrival of fresh troops on the flanks makes its interruption possible.

One must never, therefore, in reliance on this possibility of withdrawal, allow one's self to be led into the mistake of keeping the led horses too close at hand; but the resolution to engage in a dismounted action must always involve measures which fully recognise the serious possibilities such decision entails, and must be on a scale which will insure the necessary vigour of execution.

Hence, since in all cases in which a serious dismounted combat is absolutely necessary it is essential that the horses should be left in the greatest attainable security, the place for them should be selected in such a manner that they are protected against possible turning movements by the enemy--that is to say, behind suitable shelter provided by the ground, or behind defiles that can be easily defended. In cases in which these conditions cannot be complied with, which in practice will often arise, their security must be provided for by a sufficient reserve of mounted men, particularly when the enemy's Cavalry is in the vicinity, for 'immobile' detachments are practically at the mercy of every mounted patrol; and as a further precaution it will be well to spread around them a sufficient web of reconnoitring and security patrols, and to arrange for the support of one's own batteries.

The covering of the led horses, however, is not the only duty of the mounted reserve: the protection of the Artillery also devolves upon it, and generally it must be ready to meet any of the demands for which Reserves are usually set aside. Hence it will have to provide not only for the safety of its own side and all pertaining thereto, but it must also threaten the enemy's flanks, undertake turning movements, reinforce, if necessary, the fighting lines, pursue the enemy, or cover the possible withdrawal of its own dismounted combatants; and, further on the offensive, it is its special mission to hold the conquered ground when the dismounted detachments are called off to remount, and to continue to carry on the original mission, interrupted by the combat, until relieved by the men who in the meanwhile have regained their horses, and again a.s.sumed the role of mounted combatants.

The first point the Commander will therefore have to decide is, how strong it will be necessary to make his mounted reserve if it is to suffice to meet all these requirements, and then whether, with the remainder of the men in hand, he has any prospect of successfully carrying out his immediate purpose. From this it will depend whether he determines to fight or to reach his object by other means. In general, the Reserve can be reduced in proportion to the weakness of the enemy's Cavalry, and to the depth of the zone of security his patrols have been able to secure for him.

Having by this line of reasoning determined the number of men he can afford to employ on foot, he must next make up his mind as to their tactical distribution.

In this case there can be no doubt that the method of employment by 'Wings' must commend itself even more than in cases involving only mounted combat, for, quite apart from all the many admitted advantages of this form, in no other way is it possible to guarantee that the dismounted men can safely and rapidly regain their horses.

The 'Line' system would involve endless confusion and loss of time in sorting them out amongst their respective commands.

As regards the general considerations of width of front and depth, the same principles apply as in the case of Infantry. In the defence to gain time is the main object, and the problem to be solved is to secure at one and the same moment both fire superiority and a sufficient reserve to meet all possible emergencies. A skilful utilization of the ground, previous ascertainment of the ranges, ample ammunition and sound fire discipline, will, as with the Infantry, be the best means of attaining one's object.

Special conditions only arise in the defence of villages where the horses can be brought under cover close to the men, and here it seems to be necessary to distinguish between several possibilities, all of which require different treatment.

If the place is to be obstinately defended, then the horses must be kept on the side away from the enemy, or in the centre of the buildings, the defence of the boundaries be suitably arranged, and the men told off to their several sections. The exits must be barricaded, and the approaches entangled with wire.

A strong inlying piquet, to act eventually as a reserve, must be placed in a central position.

If, however, the place is to be given up when seriously attacked, and resistance is only to be sufficient to cover withdrawal, then the horses should be kept saddled up in the stables, etc., and arrangements made to withdraw them rapidly without exciting attention.

In the first case, as against Infantry or mounted Cavalry only, one can count on holding one's own without serious losses for a considerable time; but the matter becomes very different if the enemy's Artillery is also to be reckoned with, for modern sh.e.l.l fire will soon involve the destruction of all the horses, and one must be prepared to find retreat practically impossible once one has allowed one's self to be committed to an engagement of this nature. Hence such positions should only be occupied and defended when it is safe to count on support from following troops, or when it is improbable that the enemy will be able to bring Artillery into action. Such situations may frequently arise in the advanced lines of a concentration zone, in which the villages nearest the enemy form part of the general system of security.

In all other cases, and particularly as regards the advanced squadrons, it will be better to take up 'Alarm' quarters, and the more unexpectedly the enemy can attack us the more stringent must be the precautions we adopt.

If we decide to retire, a portion of the men will be detached to take the horses out of the village, or to have them drawn up in readiness for mounting behind the position selected, and meanwhile the remainder of the garrison must compensate for their diminution in numbers by a greater expenditure of ammunition, thus holding the enemy till all is ready, and then slipping rapidly back to their horses. Without losses--amounting, perhaps, to the sacrifice of the last covering party--such withdrawal can hardly hope to succeed; but previous systematic arrangements give the best chance of success, and the same prevision will be equally necessary, even if the place is to be held at all costs, for the situation may always change, and a retreat become advisable.

At night, however, the aspect of affairs changes; then any attempt at withdrawal is to be deprecated, and, as a matter of principle, must not be contemplated. Even if the enemy breaks into the place by surprise, it is still better to fight him on the spot rather than to risk the certain destruction of the whole detachment by retreat. A successful resistance is in such cases all the more probable, since in the darkness the use of the enemy's Artillery is practically precluded--at any rate, can attain but little result. Only the squadrons far out in advance, and thus liable to be surrounded on all sides and captured before help can arrive, will have to be prepared for a night withdrawal before the a.s.sailants can close in around them.

As to the principles to be observed in such cases, there should be no room for doubt. Everyone should know what he has to do when the case arises.

Turning now to the consideration of the conduct to be observed in attack, it is clear that here also the same fundamental ideas apply as with the Infantry. Dismounted Cavalry must be prepared to work their way up to decisive distances, to break down from this limit the enemy's resistance, and finally to carry the position by storm. Hence the fighting line has need of constant reinforcements to give the necessary forward impulse, and hence we require the same distribution in regard to 'depth.'

Nevertheless, it would be a great mistake to adopt on this point any stereotyped formation. It must not be overlooked that the essence of such Cavalry attacks is rapidity of execution. Hence in all cases where this necessity for rapidity arises the endeavour must be made to bring from the very first as many rifles into the firing line as possible, and it follows that the greater the fire power thus obtained the less the need for subsequent reinforcement.

If we try to picture to ourselves the conditions under which these dismounted Cavalry attacks can occur, it is evident that only in the most unusual instances will the necessity arise of launching them against wide fronts of dense lines of unbroken Infantry; on the other hand, we shall often be called upon to capture isolated villages, etc., such as posts on the line of communication, railway-stations, and important defiles, and in all such cases it will always be possible to combine attacks simultaneously against both flanks, front and rear. Thanks to its mobility, the Cavalry is exceptionally well suited to the performance of such undertakings, because it can combine both attack and surprise to the best advantage.

If, thanks to this possibility, it is practicable to diminish the weight of the front attack, it follows, again, that less depth--_i.e._, fewer successive reinforcements--will require to be provided; but these can only be suppressed altogether when the object aimed at does not imply the actual maintenance of the position to be a.s.saulted, but our purpose is only to reach a point from whence to overwhelm the enemy with fire, previous to riding him down by our closed squadrons, or to break off the action again and retire as soon as a counter-attack develops. These are cases which will often present themselves: either when in pursuit it is desirable to strike unexpectedly at the enemy's columns, or during a battle, when it is feasible to molest and disturb his reserves.

In the above paragraphs I have put together the chief points to be considered in the action of dismounted Cavalry when acting unsupported; it remains now to consider the role a.s.signed to the Horse Artillery allotted to it, if only to bring out those parts which, in my opinion, lie beyond its proper field.

If we admit that in general, as between two great Cavalry ma.s.ses in actual collision, the guns can play an important part, I must yet insist that the measure of this importance should not be overdrawn; for it is only when the former are confined to a defensive att.i.tude--for instance, when they are still under cover or behind sheltering folds of the ground, or when moving in a widely-extended screen to mislead the enemy and tempt him into fire-swept ground, in order to fall upon him when he has ventured into the trap--that much is to be expected from their co-operation.

But as soon as the Cavalry begins to advance, the part the Artillery has to play drops into the background. Then the guns become simply an impediment, because, since they generally require a special escort, they subtract from the total force available for the actual shock, and always act more or less as a pivot, which hampers the free movement of the Cavalry.
