The Director of the manoeuvres can also do much to make the operations instructive for the Cavalry, and also to stimulate the interests of all engaged, if he takes care that the demands made upon the Cavalry are kept within reasonable limits. It constantly happens that patrols are despatched at far too late an hour to make it possible for their reports to arrive in time. Commanders, again, frequently wish to be informed as to the exact position of every battalion on the other side, although they generally know his total force with accuracy, or they want to know the exact strength of the Garrison holding a certain village or locality, as if Cavalry could under any circumstances supply such information; and if at night no sketch of the enemy's outpost line has been handed in, the Cavalry are held to have failed in their duty. All these demands are, in my opinion, entirely unpractical; in War one never has such precise information, and no rational man dreams of wasting the strength of his Cavalry in endeavouring to secure such details. These things are mere remnants of the Paleolithic Age, and only justifiable as an extreme case when perhaps planning a surprise. Further, it is thoroughly unpractical to require under all circumstances complete information as to the progress of an engagement. With modern weapons this is impossible, unless favoured by unusual topographical conditions. Not merely are such demands unpractical, but they exercise a most prejudicial effect, for too accurate and too detailed information gets the Generals into bad habits of command, and the Cavalry itself is well-nigh ruined. Certainly, when circumstances demand it, the men must not be afraid to keep well up to the enemy, and bring back intelligence even out of the zone of his fire; but, generally, reliable observations are only made out of range. The Cavalry must learn principally to judge the enemy's arrangements from a distance; they must direct their attention to the essential only, and not waste their time in unnecessary side issues. If justice is to be done to these requirements, it is quite impossible to collect all the information the Generals so frequently require. Thus they get in the habit of observing in an unpractical manner, and the whole of this most important branch of their education suffers accordingly. So much is this the case that nowadays the patrol leaders often exchange mutual confidences to one another, as it is practically impossible, owing to conditions of time and space, to obtain the required information otherwise, and they consider it better to get it in this manner than to accustom their men to unpractical feats of riding. Reconnaissance and its results can only be of value to the training when kept within the limits that the nature of things dictates.
