Cavalry A Popular Edition of "Cavalry in War and Peace"
Part 12
First and foremost, I think that it follows, from the above arguments, that, in the case of cavalry operating independently, engagements may often take place which, with a generally offensive intention, must be conducted at times in a defensive spirit and with only part of the troops--that is to say, where it is not the intention to act on the defensive with the whole force, but to use the defence only as a means of resuming the general offensive later at the most advantageous time. It will be possible, especially in the battle of encounter, to defend favourable positions or localities with the advanced troops, either to gain time for the arrival of the main body, or else to oblige the enemy to weaken his reserves, against which the offensive is intended. This combination of attack and defence will frequently occur, I am convinced, even in the battle of encounter.
In such cases the defence must endeavour to deceive the opponent and to provoke the attack. Efforts will be made, while putting but few men into the fight, to give the impression of strength in the firing-line, and yet so to dispose the troops that attack will not appear impossible, if carried out in sufficient force. Groups of men on a broad front, a liberal expenditure of ammunition, and sometimes the holding back of artillery and machine-guns, are the means whereby the enemy may be thus misled.
But, even if the defensive on a large scale is adopted because the force is considered too weak to take the offensive in the open, the guiding principle will still be, as I have already indicated, to obtain a decision in the defensive fight by an offensive counter-stroke, in so far as the force and the circumstances of the ground in any way permit. This is a fundamental principle of the spirit of cavalry.
The force destined for the counter-attack should accordingly be detailed from the first. Efforts must be made, by using favourable country for the defensive front and thus being able to occupy it weakly, to spare every available man for the counter-attack, and to compensate for the weakness of the force in position by ample ammunition, well-arranged cross-fire, and similar measures. The troops designed to play the offensive rôle must first be placed in reserve, withdrawn, as far as possible, from view and fire of the enemy. As soon as the situation is cleared up, they will be placed in échelon behind that flank from which the counter-stroke will take place. Whether this will be a mounted or dismounted attack depends on the character of the ground and similar circumstances. In any case a base for attack outside the limits of the enemy's fire must be reached, and, where possible, by surprise.
It is therefore of the highest importance that the enemy shall be prevented from gaining observation as to the conduct of the reserve, in order that its presence may eventually come as a surprise to him. Hostile patrols must be attacked with remorseless energy wherever seen, and, if possible, put out of action. Those look-out points, on the other hand, from which observation can be made of the enemy must be occupied early in the fight.
The cavalry will, as a rule, only undertake a completely passive defence, where the object of the fight is to hold the crossing over some obstacle, to defend isolated localities, or to gain time. In such a case the question is one of the obstinate defence of a definite object, sometimes perhaps, also, of a retirement from one point to another. Such an operation, however, is always difficult to carry out on account of the led horses, and should only be attempted in very favorable country. It demands that the fight shall be broken off--always a difficult matter, and, to cavalry encumbered by their led horses, one of considerable danger. The horses certainly render it possible, by making a proper use of the ground, to withdraw more rapidly than could infantry in the same case. On the other hand, however, they tie the dismounted troops down to a definite direction of retreat, and remounting, when pressed by the enemy, is always a critical matter.
4. _Breaking off the Fight, Retreat, and Pursuit_
When it becomes apparent during the course of a fight that success cannot ensue, the commander must decide in good time whether he will carry the engagement through or break it off. To choose the right moment for the latter operation is generally extraordinarily difficult, even when it has been planned from the commencement. To make the necessary dispositions, also, demands great tactical skill. To continue the fight with determination, perhaps till nightfall, will often cost no greater sacrifice than the breaking off of the engagement and the attendant retreat.
Generally speaking, such engagements will only be those which are fought out on foot. The more open the country, the closer the enemy, and the greater the number of troops which have already been thrown into the fighting-line, so much the more difficult will it usually be to break off the fight. The circumstance also as to whether the led horses are mobile or immobile, and their position, will naturally influence the decision. On the other hand, it is easier to extricate the force after some success has been gained; whether it be that a hostile attack has been repulsed, or that our own troops have made a successful counter-stroke. History teaches us that at such moments there is generally a lull, during which the opponent is obliged to bring up fresh troops or to make fresh tactical dispositions.
Even under such favourable conditions, however, it will generally be impossible to break loose from the enemy without suffering heavy loss.
In defence, if the ground is especially favourable, it will certainly be possible at times to extricate a force without considerable loss. If it can rapidly withdraw from the firing-line and retire covered from pursuing fire, the whole force may under certain circumstances simultaneously evacuate a position, that is to say, if the enemy is still so far distant that he is unable to employ pursuing fire until the defender has reached a place of safety. How seldom, however, will such be the case! Small detachments will generally have to be sacrificed to secure the retreat of the main body. This means that various especially strong supporting points in the position will be occupied, and the force will withdraw under cover of them.
Military history offers us repeated examples where the attacker makes desperate endeavours to overpower such points, and in so doing forgets to pursue the withdrawing masses of the defender's troops. This, for example, was the part played at the battle of Weissenburg by Geisberg Castle and Schafbusch, and the château with its enclosed park at the battle of Coulmiers. Under cover of these points, against which all the efforts of the French were concentrated, the defenders were able in both cases to withdraw so slightly molested that even touch with them was completely lost.
The defence of such supporting points, which must be conducted with the utmost obstinacy, frequently ends in capture, but the end gained is worth the sacrifice. If the endeavour is made to withdraw the whole line of defence simultaneously under circumstances where it is possible for the attacker to bring to bear an effective pursuing fire from the captured position, loss will generally be much greater than that which would be deliberately incurred in arresting the pursuit.
The conditions are similar in attack. At manoeuvres certainly we see the attacker when repulsed turn about, and, in a continuous retreat, lay himself open to a pursuing fire, which would mean absolute destruction. I do not think such a manoeuvre possible in reality. As the advance has been by stages, so must be the retreat. But, whereas in the advance it was a matter of pressing forward on a wide connected front, in order to hold the whole of the enemy's position under fire, and _not_ of massing together where cover could be obtained, the exact contrary is the case in retreat, and the troops must seek any cover that will shelter them from the fire of the pursuit. Various strong points in the attack which have already been taken and occupied must be obstinately held during the retirement, and from them a heavy fire poured into the pursuit to bring it to a standstill. Care should be taken, even during an advance, to keep such places well supplied with ammunition, which can either be taken forward to the captured position or be at the disposal of the retiring troops.
I do not think that it will be possible in any other manner to break off an attack which has penetrated to within effective range of the enemy, or to carry out a compulsory retreat without disastrous loss.
The troops must fall back, obstinately contesting the ground and continually recommencing fire from any favourable position. The commander must make careful preparations, even when advancing, that a possible retreat shall not lead to disaster, but will be able to find prepared points of support. All detachments, however, that are outside the effective range of the enemy's fire, and still capable of manoeuvre, especially artillery and machine-guns, must from commanding positions bring fire to bear on those troops which are harassing the retreat, regardless of the losses they may themselves incur. In such a moment everything must be subordinated to delivering the retreating masses from that destruction which the fire of the pursuit portends. Any advance of pursuing cavalry, also, must be met by heavy fire from such detachments, regardless of the expenditure of ammunition.
A retreat, then, requires particularly intelligent handling. The various detachments must be provided with instructions that are clear and definite. The commander must have his troops well in hand, must arrange for the occupation of any positions, decide which detachments shall cover the retreat, dispose of the artillery and machine-guns, determine the line of retreat of the various units, with due regard to the situation of their led horses, and arrange for the occupation of the rallying position. He should himself only leave the field when the force has got clear of the enemy. He must then, however, straightway attend to the rearrangement of the tactical dispositions, and take the other necessary measures. Any reserve still in hand must be used to check the pursuit where possible by a vigorous offensive. It is just in such situations that a determined counter-attack, even by a weak force, makes the greatest impression on the enemy.
As to the further conduct of the retreat after a successful extrication, definite instructions are naturally impossible. Everything depends on the circumstances of the moment. The possibilities of resuming the offensive must be borne in mind, even during a retirement. To this end it is frequently advisable to fall back partially towards a flank. Gneisenau, after the defeat at Ligny, directed the retreat on Wavre, in order to be able to take up the offensive again on the following day, and thus supplied us with a brilliant example well worthy of imitation even where the forces engaged are but small.
If it is a matter of mounted combat, the breaking off of the actual fight is quite impossible. Troops once engaged must carry the fight through. Even when retreating from the mêlée, fighting cavalry has no kind of means of extricating itself. It is then entirely dependent on the enemy, and can only retire at the most rapid speed. Reserves alone are able to bring the immediate pursuit to a standstill by intervening in the running fight. Generally, however, this will only end when the horses of the victor are quite exhausted, or when the latter feels the necessity of getting his troops in hand and forming again for fresh duties. The further conduct of the vanquished troops must depend on the condition of the horses and the general situation. It is of importance to withdraw beyond the reach of the enemy as soon as possible in order that full freedom of action may be regained.
If the fire of the hostile artillery is to be feared, it is advisable to retire extended without regard to tactical formations, and making the best possible use of the ground. The troops will then only rally again beyond the range of the enemy's fire. The same naturally holds good for the retreat from a dismounted action after the men have remounted.
The commander will be well advised to inform his senior subordinates, if not all the troops, before the fight begins where the troops are to concentrate again in case of a reverse. The necessity for such dispositions generally passes unnoticed in peace, because pursuit is never thoroughly carried out, and the beaten troops are not so completely broken up as has repeatedly happened in war in the past and will happen again. We should not deceive ourselves in this matter, as otherwise there is a danger of completely losing control over the troops. Whoever expects to be able to rally a beaten cavalry division after a mounted fight by blowing the divisional call lays himself open to bitter disappointment. If the enemy is pursuing with energy, this will only be possible in the very rarest cases.
Before the commencement of the fight, arrangements must also be made for the rear communication, as there will otherwise be a danger of losing transport, and thereby ability to operate. Far to the rear or close at hand are the two only possible positions for it. In the first case an escort whose strength will be dictated by the circumstances will always be necessary.
It should also be remembered that wagons should be able to turn round where they are halted. If single teams are unable to turn about on their own ground, it will be better to park the whole of the transport in such a way that it can easily be moved in any direction. It is then also easier to protect it against attack. If there is no fear of attack, the various columns may turn off the road with intervals corresponding to their length. It appears to me to be of especial importance to lay stress on these circumstances because in peace exercises there is no transport, and commanders consequently get accustomed to paying little attention to it.
As regards the pursuit, it is necessary to differentiate between a tactical and a strategical pursuit. The latter must crown the success of the former.
In mounted action, the beaten opponent must be kept at the point of the sword as long as the strength of the horses hold out. Detachments not immediately pursuing must be concentrated, and must seek to regain their ability for manoeuvre as soon as possible.
After a dismounted action on the defensive, the pursuit will first be taken up by rifle fire. Any mounted reserve there may be should be launched to the charge against the retiring enemy as soon as the pursuing fire begins to cease to be effective. A victorious attack, on the other hand, must make every endeavour to gain the position vacated by the enemy, and to occupy ground from whence an effective pursuing fire is possible. The bringing up of the led horses will be of special importance in this case. If they are immobile, a portion of the men must be sent to the rear to bring them up, while the remainder hold the captured position. Any mounted reserves there may be can often be employed to bring up at least a portion of the led horses. Generally speaking, however, all troops not already engaged must, as we have already shown, take up the strategic pursuit as early as possible. This will supplement and complete the results of the tactical pursuit.
Never to let the enemy rest, even when the tactical pursuit has ceased, to prevent him regaining his cohesion, to capture prisoners, horses, and trophies, and, above all, to increase to the utmost the moral effects of his defeat, is the task before us. The immediate pursuit must therefore be combined, wherever possible, with a parallel pursuit commenced in good time. The latter must nip in the bud every attempt on the part of the retiring enemy to take up rearguard positions, by turning such positions and pressing forward with reckless energy against the actual lines of retreat. It must also endeavour to anticipate the enemy in the occupation of any defiles necessary to his retreat. At such times there must be no thought of sparing horseflesh. Even in this pursuit, however, the commander must give a definite object and a rallying point for the detachments following. He will otherwise, by reason of rapidity of the movements in progress, risk losing control of at least part of his troops, and of allowing them to go farther than the strategical situation demands or admits. For the rest, I may draw attention to the new Cavalry Drill Regulations, the compressed instructions of which contain much that is essential and coincide generally with my views.
V. THE ACTION OF CAVALRY IN BATTLE
In the battle of all arms, cavalry must be handled according to principles which are quite different and almost diametrically opposed to those which characterise its independent action as army cavalry. For, in the latter case, not only is the defeat of the enemy kept in view, but another definite object has also to be pursued. This object can only be attained if successful in the fight, while an unsuccessful battle will paralyse the activity of the cavalry, and may cost the army the loss of its organs of reconnaissance. However daring its conduct then, it should never be engaged in hopeless enterprises, and should only undertake a fight where success can be reckoned upon with a certain measure of probability.
If, therefore, the strength and intentions of the enemy are not fully known, it will be better, as we have seen, to guard against engaging the whole force in such an uncertain enterprise. Efforts should rather be made, as I have endeavoured to show, to clear up the situation by a careful feeling of the enemy and a gradual engagement of force. Once possessed of this knowledge of the situation, it will be possible either to seek a decision or to break off the fight in time to avoid the risk of incurring too considerable a loss.
Quite different is the case in the main battle. Here the objective is contained in the battle itself. It is the destruction of the enemy that is sought. It is not expected that each single detachment engaged should be victorious, but that the net result of the battle should be a victory. The task of the various detachments is only to engage and to destroy so much of the enemy's force as lies within their power. This naturally holds good for the cavalry. It is not now demanded that each single action of the cavalry should of itself be successful, but that the general engagement of the cavalry should have the greatest possible effect. A considerable result may often be obtained by the attacking cavalry drawing the enemy's fire upon itself for a time, and thus affording the infantry the possibility of gaining ground to the front, or of re-forming and receiving reinforcements.
To break off the main battle is generally quite out of the question. The very fact that the battle has been begun betokens the intention of carrying it through to a final decision, even where the enemy has shown himself to be in superior force. The various troops which advance to the conflict need not therefore reflect whether _they_ have any special prospect of success, but must strive for this success with all their power. This means for the cavalry, in by far the greater number of cases, always at least where a charge is in prospect, _the simultaneous engaging of its whole fighting strength_, naturally in that tactical formation which the conditions of weapons demand. If in its _independent_ operations cavalry must be dealt with as a strategical body, and thus employed in the fight, it is _in the main battle_ a purely tactical body, which must be engaged _en masse_, and not in detail. This contrast appears, at least to me, to be an obvious one. There is another that is equally clear.
In independent operations it is the duty of the cavalry, before all else, to defeat the enemy's _cavalry_. Victory over the latter creates the possibility of carrying out its proper task, that of reconnoitring and screening, without being involved in further fighting on a large scale. In the main battle, however, it would be taking quite a false view of its duty if it were to restrict itself to driving the hostile cavalry from the field. Victory over the latter has indeed a certain value, as it paralyses its further action, but it will, in most cases, be comparatively useless for the main issue of the battle unless further consequences result from it. A victory over the hostile cavalry only receives its particular importance when by it the possibility is gained of intervening in the decisive encounter _of the other arms_, and of acting unhindered when, in the course of events, it becomes a matter either of pursuit or of covering a retreat.
Finally, in independent operations, even small detachments can aim at great results, and a division of force will frequently be indicated. In the great battle, however, any considerable effect can only be attained by the action of the mass. The reason for this lies in the size of modern armies.
It will be advisable to concentrate the mass of the cavalry at what are considered the decisive points, in order to be able to engage it simultaneously. Any frittering away of force upon the field of battle will strike the troops with impotence. We have only to remember the battle of Coulmiers, where the richest prospects of success confronted a cavalry which achieved nothing, because it did not act in concert. Where great tactical units have to be concentrated which are not under a single command, it will be advisable that the laws of seniority be set aside, and the command given to that leader from whom the best performances are to be expected, even though he be not the senior. In the cavalry, more than in any other arm, success depends upon the leader. Nothing is more rare than a good cavalry leader, and it would therefore be a great mistake to ignore such a one, and thus perhaps to sacrifice the fortunes of the day to the Moloch of Seniority. We should rather act like Frederick the Great at Rossbach, when he placed Seydlitz at the head of his cavalry, and we must expect from Prussians to-day the same generosity as Frederick's generals showed in willingly serving under their junior.
The best of leaders, however, will only be capable of great performances if he is fully acquainted with the intentions of the Head Quarters and the idea of the battle. He must therefore be not only closely informed before the fight, but must remain throughout its progress in continual communication with the Head Quarters, and must be made aware of all dispositions and at the same time must share its observations and be in touch with its intentions. The German cavalry would certainly have been able to fight a more successful and connected action at Mars la Tour, as at Coulmiers, if it had been better informed as to the general situation, and had thus been in a position to appreciate for itself what was necessary and what was possible.
