Thus it appears to me we could achieve a considerable reduction in the amount of practical drill necessary, and the change would tell all the more the more frequently the call was employed, until at last it became ingrained in the very flesh and blood of each man in the ranks. Unfortunately the Regulations do not allow their employment in this sense, but permit them only as cautionary sounds (Section 115, note); but even in this restricted sense they deserve most constant use in drilling, for they are always a means of preventing, in a measure, misapprehensions in the execution of other sounds. We come now to the second portion of our requirements--viz., how to obtain clearness in the appreciation of tactical principles. Fortunately they are few in number, but it is absolutely indispensable that every Cavalry Leader should most fully have mastered their meaning. No knowledge, however accurate, of the formal prescriptions of the Regulations can in any way compensate for a deficiency in this respect. They are certainly not indicated as 'General Principles' in the Regulations themselves, but may be read between the lines with more or less precision from its several paragraphs. FOR CAVALRY VERSUS CAVALRY. 1. The German Cavalry must always endeavour to attack first in order to utilize to the utmost its superior 'moral,' and to catch the enemy in the act of deployment. If an opening for such an attack is offered, then even the risks of a long preliminary gallop must be accepted (Section 339). 2. The leading lines must _always_ be followed by supporting squadrons in adequate numbers (Section 843, and note also Section 346); that is to say, the enemy's Cavalry will always be attacked in two 'Lines,' unless special circumstances compel departure from this prescription. 3. One must always endeavour to keep the last closed Reserve in hand, because in the melee the impetus of the last closed body generally decides. One must never, therefore, as long as one suspects that the enemy has still further Reserves in hand, engage a greater number of squadrons than he shows, in order to save up Reserves. 4. Success must be looked for in the vehemence of the onslaught, not in superiority of numbers (Section 313). The greatest importance must be attached to cohesion; hence, unless necessary to surprise the enemy in the act of deployment, the 'gallop' should not be sounded too soon, or the 'charge' too late (Section 339).
