Corps de Garde, a post in an army, sometimes under covert, sometimes in the open air, to receive a body of soldiery, who are relieved from time to time, and are to watch in their turns, for the security of a quarter, a camp, station, &c.—The word is also used for the men who watch therein. It is usual to have, beside the great, a little corps de garde, at a good distance before the lines; to be the more readily advertised of the approach of the enemy.
