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.
