BERME, noun In fortification, a space of ground of three, four or five feet in width, left between the rampart and the moat or foss, designed to receive the ruins of the rampart, and prevent the earth from filling the foss. Sometimes, it is palisaded, and in Holland, it is generally planted with quick-set hedge.
