Picquet-GUARD, a good number of horse and foot always in readiness in case of an alarm: the horse are all the time saddled, and the riders booted. The foot draw up at the head of the battalion, at the beating of the tattoo; but afterwards return to their tents, where they hold themselves in readiness to march, upon any sudden alarm. This guard is to make resistance, in case of an attack, till the army can get ready.
