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.

If, however, understanding between the commander-in-chief and the leader of the cavalry is established, and if full confidence in the judgment and energy of the latter exists, he must be allowed that necessary freedom and independence which alone ensure successful action. On the other hand, he should never wait for orders to intervene, but must himself turn any favourable moments of the fight to account by rapid and energetic independent action. Even if he is definitely placed at the disposal of the commander, he should not shrink at critical moments from acting on his own responsibility, informing, of course, his superior officer of his actions. As an example of the relations between the supreme command and the cavalry leader I would draw attention to the conduct of King Frederick and General von Seydlitz in the battle of Zorndorf. The King felt the necessity of restoring the wavering fortunes of the day by launching the cavalry to the attack, but Seydlitz independently chose the moment for the charge; and success justified them both. When, however, in the battle of Kunersdorf, the General was compelled to order the charge against his better judgment, the consequences were a heavy defeat for the cavalry.

1. The Army Cavalry on the Flank of the Battle

I have already repeatedly indicated that the most favourable position for the army cavalry is to a flank and in advance of a flank of its own army, and, where possible, of that flank on which, in the battle of offence, the decision will be sought, or, when in defence, the main hostile attack may be expected.[40] The new Cavalry Regulations adopt this point of view. It is therefore superfluous to comment further on the advantages of such a position. Unless the cavalry is going to resign all claim to offensive action, this position will compel it to seek battle. This may also happen when the cavalry masses of both sides endeavour to take up such a position, and thereby naturally come into collision, so that a sort of battle of encounter results, but one, however, that will bear quite a different character from the battle of encounter in strategic operations.

There will already be a difference, in the fact that the strategic approach and the tactical disposition in advance guard, main body, and reserve, will be wanting. In the consciousness, moreover, that, whatever the relative strength may be, the decisive battle has, under any circumstances, to be sought, it must be prepared for systematically. The cavalry will therefore have to adopt a wider front, or even deploy while farther from the enemy, having to its front only the necessary bodies for reconnaissance and security. The reconnaissance must be of a double nature. Timely measures must first be taken to ascertain whether, on the probable lines of approach and communication of the enemy, further hostile forces, ammunition columns, or supply trains are hurrying to the battlefield. Where the squadrons already pushed forward have received the necessary further instructions, this reconnaissance will often develop from the corresponding strategic measures. It will, however, frequently be necessary to send forward new organs of reconnaissance, even up to the strength of squadrons, as is discussed in the chapter on "Close Reconnaissance and Reconnaissance for the Fight." Besides this far-reaching exploration, immediate tactical reconnaissance for the fight must also be arranged; this will, in general, be directed against such hostile troops as may be within tactical reach, and must at the same time comprise reconnaissance of the ground. This service must be carried out by contact patrols and it is obviously impossible to separate the two duties.

The reconnoitring organs suffice in such a case for safety to the front. To the flank, however, local flanking patrols must be pushed out during the advance. It may at the same time be advisable, for the protection of the main body, and as points of support for the reconnaissance, to occupy defiles and other important places to the flank or front by dismounted detachments up to the strength of a squadron or more.

Screened by these various measures, the cavalry mass now advances fully deployed for the fight. It must be écheloned so far from the flank of the army that it cannot come under the fire of its own infantry, and that it can, if in any way possible, turn the outer flank of the hostile cavalry. The latter may then easily become hampered in movement by its own troops, and will have to deploy eccentrically, a disadvantage under any circumstances. Connection with our own army must, naturally, not be lost, so that in case of an unfavourable issue of the fight the cavalry may not be completely severed from it. The tactical dispositions, which should always be of an elastic nature, must obviate this.

That depth must be maintained in so far as it allows the necessary frontage, is easily understood. In deploying concentrically the various groups do not by any means need to be in touch, as during the advance they will gradually approach each other. They can, or rather must, be disposed at wide intervals, and it is better that these should be too great than that the necessary depth should suffer. A reserve must always be detailed and at the disposal of the commander, in order that he may retain his influence over the decision and be ready to meet the vicissitudes of the conflict.
