any danger, the rapidity of movement made that kind of relief impossible.
But when from any cause the course of events is less impetuous, when a more even oscillation and balancing of forces takes place, then the housing of troops must again become a foremost subject for attention. This want has some influence even on the conduct of war itself, partly in this way, that we seek to gain more time and security by a stronger system of outposts, by a more considerable advanced guard thrown further forward; and partly in this way, that our measures are governed more by the richness and fertility of the country than by the tactical advantages which the ground affords in the geometrical relations of lines and points. A commercial town of twenty or thirty thousand inhabitants, a road thickly studded with large villages or flourishing towns give such facilities for the assembling in one position large bodies of troops, and this concentration gives such a freedom and such a latitude for movement as fully compensate for the advantages which the better situation of some point may otherwise present.
On the form to be followed in arranging cantonments we have only a few observations to make, as this subject belongs for the most part to tactics.
The housing of troops comes under two heads, inasmuch as it can either be the main point or only a secondary consideration. If the disposition of the troops in the course of a campaign is regulated by grounds purely tactical and strategical, and if, as is done more especially with cavalry, they are directed for their comfort to occupy the quarters available in the vicinity of the point of concentration of the army, then the quarters are subordinate considerations and substitutes for camps; they must, therefore, be chosen within such a radius that the troops can reach the point of assembly in good time. But if an army takes up quarters to rest and refresh, then the housing of the troops is the main point, and other measures, consequently also the selection of the particular point of assembly, will be influenced by that object.
