If circumstances are less favourable, if the population is not so great, or if it consists more of artisans than agriculturists, if the soil is bad, the country already several times overrun—then of course the results will fall short of what we have supposed. Still, we must remember that if the breadth of the front of a column is extended from two miles to three, we get a superficial extent of country more than double in size, that is, instead of four we command nine square miles, and that this is still an extent which in ordinary cases will always admit of concentration for action; we see therefore that even under unfavourable circumstances this method of subsistence will still be always compatible with a continuous march.

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.

The first glance shows that by such a mode of proceeding the subsistence of a large army would be a matter of impossibility. The collection made from the stores in any given district in the country will be much less than if the troops had taken up their quarters in the same district, for when thirty or forty men take possession of a farmer’s house they can if necessary collect the last mouthful, but one officer sent with a few men to collect provisions has neither time nor means to hunt out all the provisions that may be stored in a house, often also he has not the means of transport; he will therefore only be able to collect a small proportion of what is actually forthcoming. Besides, in camps the troops are crowded together in such a manner at one point, that the range of country from which provisions can be collected in a hurry is not of sufficient extent to furnish the whole of what is required. What could be done in the way of supplying 30,000 men, within a circle of a mile in diameter, or from an area of three or four square miles? Moreover it would seldom be possible to collect even what there is, for the most of the nearest adjacent villages would be occupied by small bodies of troops, who would not allow anything to be removed. Lastly, by such a measure there would be the greatest waste, because some men would get more than they required, whilst a great deal would be lost, and of no benefit to any one.

The result is, therefore, that the subsistence of troops by forced contributions in this manner can only be adopted with success when the bodies of troops are not too large, not exceeding a division of 8,000 or 10,000 men, and even then it is only to be resorted to as an unavoidable evil.

It cannot in general be avoided in the case of troops directly in front of the enemy, such as advanced guards and outposts, when the army is advancing, because these bodies must arrive at points where no preparations could have been made, and they are usually too far from the stores collected for the rest of the army; further, in the case of moveable columns acting independently; and lastly, in all cases where by chance there is neither time nor means to procure subsistence in any other way.

The more troops are accustomed to live by regular requisitions, the more time and circumstances permit the adoption of that way of subsisting, then the more satisfactory will be the result. But time is generally wanting, for what the troops get for themselves directly is got much quicker.
