CALTROPS, in military affairs, is a piece of iron having 4 points, all disposed in a triangular form: so that 3 of them always rest upon the ground, and the 4th stands upwards in a perpendicular direction. Each point is 3 or 4 inches long. They are scattered over the ground and passages where the enemy is expected to march, especially the cavalry, in order to embarrass their progress.
CAMARADE. See [Comrade].
CAMION, Fr. a species of cart or dray which is drawn by two men, and serves to convey cannon-balls. These carts are very useful in fortified towns.

CAMPEMENT, Fr. an encampment. This word is also used to denote a detachment sent before the army to mark out the ground for a camp.
CAMP. With some trifling variations, camps are formed after the same manner in all countries. This principle seems general, that there should not be more ground occupied by the camp of a body of men, in front, than the extent of their line when drawn out in order of battle. Intervals are however generally left between battalions of infantry of about one eighth their front, and between squadrons of cavalry of thirty or forty paces. An army is sometimes encamped in two lines, and sometimes in three; the distance between the lines varies according to the face of the country, from 200 to 600 yards, or more.
In the distribution of the front of a camp, two feet are generally allowed for every file of infantry, and three feet for each file of cavalry. When the ground will admit of it, the infantry are usually arranged in rows perpendicular to the front; each row containing the tents of one company; and the cavalry in the same position, each perpendicular row containing the horses of a troop.
The grenadiers and light infantry are usually placed in single rows on the flanks, and the battalion companies in double rows.
A single row, or one company, occupies in front, nine feet; and a double row, or two companies, twenty-one feet, if formed of the old pattern rectangular tents, which hold only five men each. But if the new bell tents are used, 15 feet must be allowed for a single row, and 30 feet for a double row in front.
