The Rampart, A, Pl. 3, Figs. 4, 6, is an earthen mound, raised above the natural level of the ground, and upon which the parapet B is placed. The rampart thus serves to give the troops and arma ment, which are placed on top Of it and behind the parapet, a commanding view over the ground to be guarded by the fire of the defences; whilst, at the same time, it increases the obstacle to an open assault, by the additional height it gives to the scarp. The top surface Of the rampart, b c, in rear Of the parapet, termed the terre-plein, affords the troops and arma ment a convenient position for circulation from point to point, where they are sheltered from the direct views of the assailants' fire.
