In the formation for attack and the deployment, the Regulations follow the logical sequence of their point of view that, in the attack upon cavalry, no second line is necessary, and in this matter adhere to the directions laid down in the old Regulations. From my point of view, this does not seem to correspond at all with the necessities of the fight.
In my "Reflections on the New Cavalry Drill Regulations" I laid down "that it should always be possible for cavalry to change from the manœuvre column straightway into attack formation with flank protection, without first forming line, as hitherto has been deemed necessary." In opposition to the Regulations I still hold fast to this principle.
We have seen that the formation in lines is the necessary one for all charges, and that an attack in one line will only be possible in exceptional cases where weakness forbids the formation of several lines, or where the surprised and demoralised condition of the enemy appears to render a second line superfluous.
The logical conclusions resulting from these reflections are that all column formations employed in the approach march must keep in view first and foremost the rapid adoption of the attack formation, and that deployment must in principle lead to the formation in lines for attack. The complete deployment in line of any units from the regiment upwards can only be necessary in exceptional cases. It can be formed from the attack formation or direct from column when specially ordered.
Taking into consideration the rapidity with which approach, deployment, and attack will often follow each other, I would even advocate that a trumpet-call, "Form for attack!" should be laid down in the Regulations. The strength of the various lines will generally have to be ordered according as the objective consists of cavalry or troops using fire action. It will not always be possible to find time for detailed arrangements, particularly during the rapid vicissitudes of a cavalry combat. The trumpet-call would then justify itself, and the lines would be formed by the independent action of squadron leaders, according to the formation the troops were in and the expected breadth of frontage of the enemy. It should be laid down as a guide that of four squadrons one at least should form a second line, and that an unprotected flank should, when possible, be covered by a squadron in échelon. The squadrons nearest the enemy would form a first line, and the remainder would act according to circumstances, and either follow the first line, échelon themselves in rear of it, or, when necessary, prolong it. For the deployment into one line a special call could be used.
For the conduct of the fight on foot the same principles hold good as for the infantry. The duties and conditions of the fight are similar, and demand similar general tactical directions. The arrangements for the led horses, however, render the introduction and the conduct of the fight considerably more difficult. There is also a certain difference according as the opponent is infantry or cavalry.
For, in the first case, there is generally no danger of a further turning movement, or of threats against the led horses from the flank or rear. In the greater number of cases when arranging for the position and safety of the led horses, only small hostile patrols need be expected. An action may therefore generally be conducted with more boldness under these circumstances than when opposed to cavalry which might seriously threaten the led horses by a mounted reserve.
These circumstances must be taken into consideration when dealing with the principles for the conduct of the led horses.
In defence, the measures required are comparatively simple. The conformation of the ground usually chosen with a view to the peculiarities of defensive action will often allow of the led horses being kept close to the firing-line, where it will also be possible to mount out of the enemy's range and to withdraw from his fire under cover of the ground. The led horses should only be left to the rear if the position is to be maintained until the enemy comes to close quarters, and then should be, if possible, behind some fresh position, where it seems likely that resistance may be renewed. In defence, the led horses will generally be left quite immobile,[23] though this method should not be considered imperative. For even in defence the led horses must be sometimes kept mobile; for instance, when it is necessary to rapidly occupy on foot some locality in the neighbourhood of which there is no suitable position for the led horses. In such a case they will have to be sent behind cover, which can only be done if they are mobile. The horses will only be kept in the immediate neighbourhood when it is intended merely to bring off a fire surprise, and not when carrying out an attack or making an obstinate resistance (471-473).[24]
For the attack the conditions are different. The troops must then be often completely separated from their horses. It is therefore all the more necessary that the latter should be secured against all hostile attack. If, for instance, hostile cavalry threatens, they must have a special escort. The possibility of a reverse must be taken into consideration when selecting the position for led horses, and the retiring troops must be able not only to mount, but to withdraw under cover.
