We must not, however, assume that this deployment—in a cavalry division, for instance—requires that the various brigades shall draw away from each other at regulation intervals, and that the division will, in this formation, advance towards the enemy. This will generally be impossible; first, because it is usually advisable to seek the cover of the ground in order to be secure from possible hostile fire surprise, even when the enemy's artillery is not yet located; secondly, because the regulation frontage of deployment of a cavalry division is much too narrow to allow it to gain exterior lines, or to affect a concentric attack. The deployment must rather be carried out according to the demands of the situation at the moment, without regard to regulation intervals. The division commander will first of all detail a reserve for himself. To this he will then give the orders necessary for its conduct as well as to the advanced guard, the various groups of the main body, and the artillery and machine-guns. The direction of march of the various subdivisions will thus be determined according to the ground and the intentions of the commander, and it will also usually be necessary, in order to keep the troops well in hand, to order the advance by stages, and to regulate the pace.
If the advance has been carried out in separate columns, the action of the smaller columns must be regulated before the deployment of the main column. A certain loss of time will here generally be found inevitable. The necessary preparations must therefore be made early enough to ensure that, if the junction of a detachment with the main body is intended, it will be possible to carry it out before contact with the enemy is made. It is a matter for especially careful and well-considered action if one of the lesser columns is to intervene from a flank direction in a fight which is already raging, an operation which may be of the most decisive importance, but difficult to effect in the rapid course of cavalry action. If, however, it is desired to reap the benefits of such action, an endeavour must be made to gain time by dismounted action for the arrival of the column which is to strike the decisive blow. Such measures will always be risky, but may lead to glorious results.
The orders for the concentration and for the deployment form the framework on which the whole fight develops. They are therefore of the highest importance. Faults committed here can seldom be rectified later, and yet such orders will generally have to be issued before touch with the enemy is gained, except by patrols, and at a moment when the main features at most of the enemy's situation are known. Particular attention must, as we have seen, be paid to his artillery. No one will deny that herein lies the possibility of misapprehension and failure, and that many a leader will shrink from the necessity of such a decision. He, however, who, in spite of the uncertainty of the situation, succeeds in making up his mind betimes has an obvious advantage. For it is just in such a battle of encounter that success will fall to him who knows how to avail himself with rapidity and determination of the favourable moment, who quickly possesses himself of important points and localities, and who anticipates the enemy, as advocated above, in broadening the front, and thereby in deployment.
Under such circumstances the dispositions made for the advanced guard will be of the greatest importance. Its conduct has often a deciding influence on the issue of the whole fight.
If it be carelessly handled, this circumstance may mean the loss of the initiative, and the commander may find himself compelled to turn his attention to the situation forced upon him by the advanced guard, and to conduct the fight otherwise than his own intentions and the general situation demand. On the other hand, a too careful employment of the advanced detachments is apt to entail loss of advantages which might be of decisive importance. The proper conduct of such an advanced guard demands, therefore, an unusually sure military instinct. Its commander must always be instructed in a detailed manner as to the intentions of the general, if he is expected to handle his detachment successfully according to them.
It will often be advisable for the advanced guard to occupy some point of support dismounted, in order that the deployment and the further tactical development may be undertaken under cover of it. In such circumstances there is no reason to shrink, when necessary, from bringing the advanced guard back to some suitable locality, if thereby full cover can be afforded for the rear detachments or for separated portions of the force that may be rejoining. It will often be found desirable also, in the critical moments of deployment, to strengthen the resisting power of the advanced guard by machine-guns. It may, however, on the other hand, be equally advantageous for the advanced detachments, on collision with the enemy, to charge him recklessly in order to reap full benefit from some favourable opportunity.
The handling of the artillery, particularly at the moment of deployment, is of especial importance. It may be a great advantage to bring it into action before the enemy's artillery, in order to profit by any carelessness of the hostile troops in deployment and approach, and to surprise their artillery when coming into position. The conduct of the advanced guard must therefore be influenced by the fact that a suitable position must be assured to the artillery. Its fire will often suffice to induce the enemy to show his strength or to evacuate localities which he has occupied.
As long as the strength of the enemy is unknown, and the possibilities of superior force have to be reckoned with, it would be a great error to stake the whole force as soon as contact has been gained. This is often done on training-grounds in quite a systematic way, because there is always a tacit understanding that the enemy is no stronger than one's own force. In war such action might lead to the gravest disasters.
If, therefore, complete uncertainty reigns as to the enemy's strength, it will be better at first to operate tentatively with a portion of the force until an opinion can be arrived at as to whether the decisive attack can be ventured on. Energetic contact with the enemy by fire action will generally soon clear up this point.
The view that a gradual and judicious employment of force is not in accordance with the principles of cavalry action (430)[30] can only be justified in the case of the pure cavalry combat mounted. This, however, in my opinion, should only be determined upon if the enemy's strength is known, at all events to some degree. I do not share the view of the Regulations that, if uncertainty reigns as to the strength and intentions of the enemy, freedom of action can be preserved, even in the mounted combat against cavalry, by the use of formations in échelon (424).[31] This is only possible by a protracted action in which gradual reinforcements are used, and only in such a manner can the enemy be forced to disclose his strength and intentions. A protracted fight, however, can only be carried out by fire action. A mounted advance, whether made in échelon or otherwise, cannot alter the rapid nature of a cavalry fight, and will not allow of sufficient time being gained to form a proper appreciation of the enemy. Échelon formations lead at best to eccentric attacks and thereby to unfavorable tactical situations.
