But if a halt of several days takes place, then great distress must ensue if preparations have not been made beforehand for such an event in other ways. Now these preparatory measures are of two kinds, and without them a considerable army even now cannot exist. The first is equipping the troops with a wagon train, by means of which bread or flour, as the most essential part of their subsistence, can be carried with them for a few, that is, for three or four days; if to this we add three or four days’ rations which the soldier himself can carry, then we have provided what is most indispensable in the way of subsistence for eight days. The second arrangement is that of a regular commissariat, which whenever there is a moment’s halt gathers provisions from distant localities, so that at any moment we can pass over from the system of quartering on the inhabitants to a different system. Subsisting in cantonments has the immense advantage that hardly any transport is required, and that it is done in the shortest time, but certainly it supposes as a prior condition that cantonments can be provided for all the troops. 2.—Subsistence through exactions enforced by the troops themselves. If a single battalion occupies a camp, this camp may be placed in the vicinity of some villages, and these may receive notice to furnish subsistence; then the method of subsistence would not differ essentially from the preceding mode. But, as is most usual, if the mass of troops to be encamped at some one point is much larger, there is no alternative but to make a collection in common within the circle of districts marked out for the purpose, collecting sufficient for the supply of one of the parts of the army, a brigade or division, and afterwards to make a distribution from the common stock thus collected.
