A further cause is to be found in the Regulations themselves. These give no firm foothold for the decision of the question as to what forms and movements really are practicable in War-time, and, probably in the endeavours not to hamper too much the initiative of the Leaders, does not express the principle on which the conduct of the combat is based with sufficient precision to preclude very different opinions as to what these principles really are. Finally, the local conditions of many of our garrisons often create an almost insuperable difficulty for the proper training of the troops over country. In face of these conditions, we must strike out new paths for our guidance if we do not intend to remain behind the times altogether. We must first, however, be perfectly clear in our own minds as to which of the Regulation forms are really practicable, and hence require increased attention. Then we must endeavour to formulate the guiding principles for the conduct of an engagement in a manner so clear and definite that they can easily be fixed in the memory, and then work out the best way in which the troops can be thoroughly grounded in their application. Finally, we must acquire a quite distinct grasp of what can be practised over country, and from what points of view such exercises are to be undertaken in order to make them of direct utility in the solution of the problems modern Warfare will set before us. To clear up the first point it will be best to sketch in its general outline the course in which events succeed one another in an engagement, and then to deduce the forms of movement which are essentially practical. Taking the case of Cavalry in combination with the other Arms, at the commencement of the action we find the squadrons in 'rendezvous' formation under cover outside the immediate danger sphere, either on the flanks or behind the general line of battle. When the moment to act arrives, they advance at a rapid pace, either in closed-up column of route or in any other dense formation which permits of ready deployment in the direction of their allotted target. Often in this movement they will have to overcome difficulties of the ground--defiles and the like, of varying breadth. Arrived in the vicinity of the field of attack, they deploy into lines of squadron columns, form line to the front, and execute the charge. In such cases it may often become necessary to secure one's own flanks by forming protective echelons, or to endeavour to surround those of the enemy by corresponding offensive movements. In the case of Cavalry acting alone, it will often be necessary to form for action directly from column of route, and it will be essential to establish co-operation not only between the advance guard and the main body, but also between columns concentrating from different directions upon the field of coming action.
