The term is sometimes more extensively used to include all the means for lodging and sheltering the soldiers during a campaign, and all the arrangements for cooking, &c., either in the field or in winter quarters.

A camp, whether composed of tents or barracks, or merely places assigned for bivouacking, must be divided and arranged in such a way that the several divisions shall be disposed as they are intended to be drawn up in order of battle; so that, on any sudden alarm, the troops can pass from it promptly, and form their line of battle without confusion.

Suitable places must also be assigned for cooking, for baggage, and for provisions, military stores, and ammunitions.
The extent of the color front of a camp depends much on the character of the ground and the means of defence, but as a general rule, it should never exceed the position which the army would occupy in the line of battle.

The different arms should be encamped in the same order as that of battle; this order of course depending on the nature of the battle-ground.

A _corps d'armee_ is composed of battalions of infantry, squadrons of cavalry, batteries of artillery, and companies of engineer troops, and the art of encampments consists in arranging each of these elements so as to satisfy the prescribed conditions.
The choice of ground for a camp must be governed, 1st, by the general rules respecting military positions, and, 2d, by other rules peculiar to themselves, for they may be variously arranged in a manner more or less suitable on the same position.
That the ground be suitable for defence, is the first and highest consideration.
It should also be commodious and dry: moist ground in the vicinity of swamps and stagnant waters, would endanger the health of the army: for the same reason it should not be subject to overflow or to become marshy by heavy rains, and the melting of snow.
The proximity of good roads, canals, or navigable streams, is important for furnishing the soldiers with all the necessaries of life.
The proximity of woods is also desirable for furnishing firewood, materials for huts, for repairs of military equipments, for works of defence, &c.
Good water within a convenient distance, is also an essential element in the choice of ground for a camp; without this the soldiers' health is soon undermined.
