We are now considering the three situations of an army outside of the combat only strategically, that is, so far as they are conditioned by place, time, and the number of the effective force. All those subjects which relate to the internal arrangement of the combat and the transition into the state of combat belong to tactics.

The disposition in camps, under which we mean every disposition of an army except in quarters, whether it be in tents, huts, or bivouac, is strategically completely identical with the combat which is contingent upon such disposition. Tactically, it is not so always, for we can, for many reasons, choose a site for encamping which is not precisely identical with the proposed field of battle. Having already said all that is necessary on the disposition of an army, that is, on the position of the different parts, we have only to make some observations on camps in connection with their history.

In former times, that is, before armies grew once more to considerable dimensions, before wars became of greater duration, and their partial acts brought into connection with a whole or general plan, and up to the time of the war of the French Revolution, armies always used tents. This was their normal state. With the commencement of the mild season of the year they left their quarters, and did not again take them up until winter set in. Winter quarters at that time must to a certain extent be looked upon as a state of no war, for in them the forces were neutralised, the whole clockwork stopped, quarters to refresh an army which preceded the real winter quarters, and other temporary cantonments, for a short time within contracted limits were transitional and exceptional conditions.

This is not the place to enquire how such a periodical voluntary neutralisation of power consisted with, or is now consistent with the object and being of war; we shall come to that subject hereafter. Enough that it was so.

Since the wars of the French Revolution, armies have completely done away with the tents on account of the encumbrance they cause. Partly it is found better for an army of 100,000 men to have, in place of 6,000 tent horses, 5,000 additional cavalry, or a couple of hundred extra guns, partly it has been found that in great and rapid operations a load of tents is a hindrance, and of little use.

But this change is attended with two drawbacks, viz., an increase of casualties in the force, and greater wasting of the country.

However slight the protection afforded by a roof of common tent cloth,—it cannot be denied that on a long continuance it is great relief to the troops. For a single day the difference is small, because a tent is little protection against wind and cold, and does not completely exclude wet; but this small difference, if repeated two or three hundred times in a year, becomes important. A greater loss through sickness is just a natural result.

How the devastation of the country is increased through the want of tents for the troops requires no explanation.

One would suppose that on account of these two reactionary influences the doing away with tents must have diminished again the energy of war in another way, that troops must remain longer in quarters, and from want of the requisites for encampment must forego many positions which would have been possible had tents been forthcoming.

This would indeed have been the case had there not been, in the same epoch of time, an enormous revolution in war generally, which swallowed up in itself all these smaller subordinate influences.

The elementary fire of war has become so overpowering, its energy so extraordinary, that these regular periods of rest also have disappeared, and every power presses forward with persistent force towards the great decision, which will be treated of more fully in the ninth book. Under these circumstances, therefore, any question about effects on an army from the discontinuance of the use of tents in the field is quite thrown into the shade. Troops now occupy huts, or bivouac under the canopy of heaven, without regard to season of the year, weather, or locality, just according as the general plan and object of the campaign require.

Whether war will in the future continue to maintain, under all circumstances and at all times, this energy, is a question we shall consider hereafter; where this energy is wanting, the want of tents is calculated to exercise some influence on the conduct of war; but that this reaction will ever be strong enough to bring back the use of tents is very doubtful, because now that much wider limits have been opened for the elements of war it will never return within its old narrow bounds, except occasionally for a certain time and under certain circumstances, only to break out again with the all-powerful force of its nature. Permanent arrangements for an army must, therefore, be based only upon that nature.
