Epaulement

(Fr. epaule ). In siege works, is a portion of a battery or earthwork. The siege batteries are generally shielded at one end at least by epaulements, forming an obtuse angle with the main line of the battery. The name is often given erroneously to the parapet of the battery itself, but it applies properly to the flanking return only. Sometimes the whole of a small or secondary earthwork, including the battery and its flanks, is called an epaulement; and sometimes the same name is given to an isolated breastwork intended to shield the cavalry employed in defending a body of besiegers.
