It must be remembered that it is always much more difficult and dangerous in the presence of the enemy to separate a cavalry mass for the fight than to concentrate it from a not too wide separation for common action against the enemy. In the first case the danger must be run of surrendering "the proud rights of the initiative" to the enemy, and of being obliged to attack eccentrically; while in the second case one is in possession of the exterior lines, and, with them, the most favourable directions for attack.
The regulation quoted should therefore result only exceptionally in a complete tactical concentration. The wish, however, to fight concentrated must never lead to a concentrated advance unless circumstances dictate such an operation as practical. Leaders of the large reconnoitring bodies will have, rather, continually to consider how they may best fulfil the task of the moment in the most practical way without allowing themselves to be bound by preconceived theoretical views. This must be their course of action, and will often enough lead to the advance in separate columns. The breadth of reconnaissance-zones will often demand such procedure.
Along the whole front, troops must be in a position to support the reconnoitring bodies which have been pushed forward. This will not always be possible from a single point on account of the distances involved. It will at times be necessary to break through the hostile screen when it is met by force of arms, without first being able to judge where this can most easily or most advantageously be accomplished. Again, complete information will not perhaps be to hand of the presence and the direction of march of the hostile cavalry, so that the concentration of force upon a single road will not appear at all desirable. It must also be borne in mind that the masses of cavalry have not only to act as fighting bodies, but at the same time to play an important part in the system of obtaining information. Communication must be maintained with the Head Quarters, as well as with the reconnoitring squadrons and certain independent patrols. In the latter case particularly, great difficulties will often arise. A cavalry leader must continually ask himself which is the shortest and safest means of communication with the reconnoitring organs on the one hand and with the army following him on the other, and how it can be maintained when hostile detachments pervade the intervening country. All these are circumstances which would lead to the adoption of an advance in separate columns.
The universal principle must always hold good for cavalry, that when a decisive struggle is in prospect all possible strength must be concentrated for it. On the other hand, it must be perfectly clearly understood that in a future war many varied and often contradictory demands will be made upon the arm. It will not always be possible to meet them all from the one point of view—that of uniting all possible strength before the commencement of a fight; the less so as in reconnaissance the fight is only the means to an end, the knowledge of the enemy being the essential. It remains for the genius of the leader to make his preparations in full freedom, and to solve the task confided to him in his own way. To hamper active operations by regulation is always a great evil.
The danger which lies in separation of force is not so great for cavalry as might appear at first sight, on account of the mobility and adaptability of the arm. For, although the Regulations lay down that on account of the rapid conduct of a cavalry fight the concentration of separate columns upon the field of battle can but seldom be successfully accomplished, this view can only be admitted in the case of the mounted combat. I am of opinion that it cannot be so difficult under ordinarily favourable circumstances to bring about such a concentration. With reliable reconnaissance early intelligence of the presence of the hostile cavalry should be to hand. It should then be often still possible to concentrate the separate columns according to circumstances, either forwards, backwards, or to a flank, and finally to unite them for the fight with sufficient room and time, and in an effective direction for attack. If, however, a portion of the advancing cavalry mass should come into unforeseen collision with superior hostile cavalry, it must fall back in a direction which will lead to concentration of force. In order gradually to lead up to, and at the right time to achieve, such a concentration from a divided advance, without falling into the error of a too close tactical concentration, presupposes that the leader is an artist in the conduct of his arm. Such an undertaking is much easier where not only mounted combat, but fire action is taken into consideration. In such a case that detachment which comes first into collision with the enemy would be able to defend itself in some strong position or behind some naturally defensible locality until the rest of the main body came up.
Good communication between the several portions is in all such cases an important factor. If necessary it must be effected by the help of the guns. Generally speaking, it will facilitate and prepare communication if the separately advancing columns are kept informed as to the rate of march, so that each column can at any moment calculate where the others will be in a given time if nothing unforeseen occurs. This also enables information to be sent by the shortest route to points which can to a certain extent be previously determined.
The arrangements for the advance form at the same time the foundation for the action of the actual reconnoitring organs and the complete establishment of the reconnaissance system. Directions for this will be found in the "Field Service Manual." It is laid down that reconnoitring squadrons will be pushed forward from the various groups of the army cavalry, and will be allotted zones of reconnaissance in the direction of the enemy. The reconnaissance itself will be carried out by patrols.
The breadth of these zones must continually alter according to circumstances.
If it be necessary to reconnoitre on a broad front with a comparatively weak cavalry, very wide zones will often be necessary. On the other hand, the closer the system of reconnoitring squadrons can be established, the more reliable the manner in which reconnaissance will be carried out, and the easier will it be to hamper the enemy's efforts at gaining intelligence. If the "Field Service Manual" lays down a certain breadth as normal, this naturally only indicates that, under ordinary circumstances, squadrons on a wider front would no longer be in a position to carry out their duties to the full; nothing more. The frontages laid down should never lead either to the perceptible weakening of the fighting value of a force by sending forward too many reconnoitring bodies, or, on the other hand, to the inability of the reconnoitring organs to cover the space demanded by the strategical situation. A well-considered allotment of areas is therefore of special importance, and a matter for the higher leader to decide. For the arrangements for reconnaissance inside the zone apportioned to him, the squadron leader is, on the other hand, correspondingly responsible. It is at the same time laid down that no squadron should interfere in a neighbouring zone.
