By this disposition, the extent of the _camp_ from right to left, of each battalion and squadron, will be equal to the front of each in line of battle; and consequently, the extent from right to left of the whole _camp_, should be equal to the front of the whole army when drawn up in line of battle, with the same intervals between the several encampments of the battalions and squadrons, as are in the line. There is no fixed rule for the intervals: some will have no intervals, some small ones, and others are for intervals equal to the front of the battalion or squadron. The most general method is, an interval of 60 feet between each battalion, and of 36 feet between each squadron. Hence it follows, 1st, That the front line of the _camp_ must be in a direction to face the enemy; 2dly, That at the head of the encampment of each battalion and squadron, there must be a clear space of ground, on which they may form in line of battle; and 3dly, That when the space taken up by the army is embarrassed with woods, ditches, and other obstructions, a communication must be opened for the troops to move with ease to the assistance of each other. The _camps_ of the Greeks and Romans were either round, square, or oval, or rather of an oblong square figure, with the sharp corners taken off; and to secure them against surprises, it was the prevailing custom to surround them with intrenchments. The _camps_ of the Anglo-Saxons and Danes were generally round, as likewise those of the Anglo-Normans. The _camps_ of the ancient Britons were of an oval form, composed of stakes, earth, and stones, rudely heaped together: but the practice of the present times is quite different; for the security of our _camps_, whose form is a rectangle, consists in being able to draw out the troops with ease and expedition at the head of their respective encampments. CAMP _of a battalion of infantry_, is the ground on which they pitch their tents, &c. The principal object in the arrangement of a _camp_ is, that both officers and men may repair with facility and expedition to the head of the line; for which reason the tents are placed in rows perpendicular to the front of the camp, with spaces between them, called streets. The general method is, to form as many rows of tents as there are companies in the battalion; those for the private men in the front, and those for the officers in the rear. In the British service the several companies of a battalion are posted in camp, in the same manner as in the line of battle; that is, the company of grenadiers on the right, and that of light-infantry on the left; the colonel’s company on the left of the grenadiers, the lieutenant-colonel’s on the right of the light-infantry, the major’s on the left of the colonel’s, the eldest captain’s on the right of the lieutenant-colonel’s; and so on from right to left, ’till the two youngest companies come into the centre.
