The rapid change from one fighting form to another must be absolutely guaranteed, and equally so the possibility for each unit to assume that formation in depth called for by the circumstances of the combat, without recourse to complicated orders and movements.[6]
If these requirements are to be fulfilled, then only such elementary movements must be prescribed and regulated as can be executed under all circumstances, as laid down in the Regulations.
These matters being settled, then tactical regulations should lay down no fixed evolutions, but should confine themselves essentially to forms and principles of action, which should be treated with the utmost clearness and precision.
It is hardly necessary to adduce elaborate proof to show that our existing Regulations by no means meet these requirements in all their sections.
Above all, the movements and deployments laid down for the Regiment are far too formal, based too much on accurate intervals and fixed prescriptions for the movements of the individual squadrons to be suitable for use on the ground which Cavalry must nowadays be prepared to traverse, or to be executed, exactly as laid down, in face of the enemy. Such evolutions are only possible on the drill-ground, where bugle-sounds and words of command can still be heard, and are far too complicated for practical use.
For instance, let us take the case of deployment to the front out of any 'deep' formation—columns of fours, half troops, or the like, which obviously cannot always be executed before the enemy precisely in the manner prescribed, because all must depend on the space available and the distance which separates us from the enemy. The head of the column must suit its movements to these conditions, and in turn the following sections must conform to the movements of the head; greater freedom of choice must, therefore, be left to the latter.
On the other hand, there are evolutions of the utmost importance before the enemy for which the book gives no guidance whatever—e.g., the rapid passage from the double column into squadron columns, either to the front or flank.
Even for the larger units all the prescriptions are by no means adapted to the requirements of active service. For instance, the relief of lines ('Treffen Wechsel') is an operation of no use except on the drill-ground, and is never attempted even in manœuvres—at least, personally I know no instance of its ever being tried, except as a matter of drill.
That a certain measure of justification may be found for this and similar formations, I do not wish to dispute.
They certainly possess great educational value as a means to the acquisition of the requisite discipline and cohesion, and they are also well adapted for movements beyond the danger zone, when it becomes necessary to steady the troops by the most absolute insistence on accuracy of movement and precision of drill; and that such cases do arise no one who has had experience of War will for one moment dispute.[7] Hence, even if one may hold the opinion that the same purpose may be equally well served by less complicated means better adapted to practical requirements, one can nevertheless subscribe unconditionally to the soundness of the principle involved. But for actual purposes of combat we require simpler forms and more freedom in their application, and in so far as the Regulations tend towards this end they show a very considerable degree of improvement; for the squadron, Section 330 provides the necessary amount of independence, and Sections 331 and 333 give sufficient freedom to the Regiment, subject only to the limitations referred to above. Section 346 in particular and Section 348 are also of fundamental importance for the higher commands.[8] Indeed, I hold the former as the most important concession contained in the whole book, for it practically initiates a new phase in the whole course of our drill evolution, by marking the commencement of the breach with the old doctrine of the Three-Line system ('Drei Treffen Taktik'). It is true that it still lays chief importance on this method, but it no longer regards it as the one royal road to success. Thus we enter on a path on which the Infantry already long ago preceded us, and which, mutatis mutandis, offers also for the Cavalry similar great and undeniable advantages. It is safe to predict that Section 346 will prove the starting-point, by sheer pressure of natural conditions, of a fresh series of development in our Cavalry Tactics.
