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.

The battalion companies are posted two by two: that is, the tents of every two of these companies are ranged close together, to obtain, though they be fewer in number, larger and more commodious streets: the entrances of all the companies tents face the streets, except the first tent of each row belonging to the serjeants, which faces the front of the camp.

The number of tents in each perpendicular row, is regulated by the strength of the companies, and the number of men allowed to each tent, which is 5 men to 7 men: thence it follows, that a company of 60 men will require 9 to 12 tents, a company of 75 men 11 to 15 tents, and a company of 100 men 15 to 20 tents; but as it always happens, that some are on duty, fewer tents may serve in time of necessity.

When the battalion is in the first line of encampment, the privies are opened in the front, and at least 150 feet beyond the quarter-guard; and when in the second line, they are opened in the rear of that line.

To distinguish the regiments, camp colors are fixed at the flanks, and at the quarter and rear guard.

The colors and drums of each battalion are placed at the head of its own grand street, in a line with the bells of arms of the several companies. The officers espontoons were formerly placed at the colors, with the broad part of their spears to the front. The serjeants halberts were placed between, and on each side of the bells of arms, with their hatchets turned from the colors.

When two field-pieces are allowed to each battalion, they are posted to the right of it. Gustavus Adolphus, king of Sweden, was the first who ordered two field-pieces to each battalion, which are generally light 6 pounders.

Distribution of the front and depth of the Camp for a battalion of infantry. The present mode of encampments differs from what was formerly adopted. The front of the camp for a battalion of 10 companies of 60 men each, is at present 400 feet, and during the late wars only 360 feet; the depth at present 759 feet, and during the late war 960. The front of the camp of a battalion of 10 companies of 100 men each, is at present 668 feet, and formerly only 592. The breadth of the streets from 45 to 55 feet, excepting the main street, which is sometimes from 60 to 90 feet broad.
