Squadrons will generally advance by successive stages, and upon those roads which appear to them to be the most important for reconnaissance. If they are provided with the light-signal apparatus, and can use it for communicating to the rear, they must keep in mind during the march itself the possibilities of being able to use it, try it on the ground, and make a mental note of points that are specially adapted for connection-stations. The whole plan of the day's march must then be made with an eye to the establishment of communication by this method. Halting-places for rest or feeding horses must be selected with regard either to good cover or to the view which may be had from them. In order to be independent of the hostile population, it is advisable for the squadron to have its ration and forage wagons with it. In case of an unsuccessful collision with the enemy these may indeed be lost. In any other case, however, they will always be at the disposal of the squadron. On the other hand, in hostile country, if they follow the squadron at too great a distance, they will often fall a prey to the enemy. Under such circumstances, if they are to be really protected, a sufficiently strong escort must be left with them, and this will react unfavourably upon the strength of the squadron. The efforts of reconnoitring squadrons to diminish the distance between themselves and the enemy as quickly as possible by undertaking excessive marches, such as are frequently seen in peace, are misdirected and unreal, and only tend to wear out the horses. In peace manoeuvres, which only last two or three days, and which have not to be sustained by a number of lame and over-tired horses, such proceedings are indeed possible, but in war they are pernicious. A squadron should be able to remain up to strength throughout a campaign, and it must be remembered that horses that go lame and are left behind will, at all events in hostile country, be lost to the reconnoitring squadrons for good. The patrols, too, must be able to keep something in hand. But, if the squadrons tax their capacity for marching to the utmost, the patrols, which are required to go still farther in advance, must be completely exhausted. If the squadrons can cover daily 25 miles and the distant patrols 35 to 40 miles, this will, I hold, be quite sufficient. More than this, on an average, cannot be expected of them. This does not of course preclude special efforts to meet particular circumstances. It will only be possible, however, to demand these efforts when we learn how to calculate the average length of march during which men and horses can be kept fresh and efficient.
