Guerite

Adapted from Aide-Memoire to the Military Sciences, Pt. I, Vol. II, plate facing p. 190Also called an Echauguette. In permanent fortifications a guerite was an enclosed and loop-holed sentry-box projecting from the masonry revetment of scarp walls at flanked angles of bastions. Its purpose was to provide a musket-proof position where sentries could see the length of the main ditch and counterscarp. The floor of a guerite projecting from the scarp was also loop-holed to serve as a machicouli for defense of the flanked angle. Since guerites generally rose above the level of the masonry scarp they tended to mark bastion salients and make it easier for a besieging army to identify the exact direction of bastion faces and select positions for ricochet batteries. Guerites also inhibited defenders from establishing defensive batteries to fire along the lines of bastion capitals. Guerites had generally fallen out of use by the middle of the nineteenth century.

As the illustration of the sentry-box at Fort Lincoln shows (to the left) these Original Image Courtesy Library of Congressstuctures could also be positioned on elevated points within a fortification and could, when time, labor, and availability of materials allowed, reach a relatively high state of refinement.
