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.

Epaulette. A shoulder-knot worn by commissioned officers of the army and navy, as a mark of distinction. The insignia of their rank are usually marked on officers’ epaulettes.

Epibatæ. In Grecian antiquity, the name given to soldiers whose duty it was to fight on board ship. They corresponded almost exactly to the marines of modern naval warfare. The term is sometimes found in Roman authors to denote the same class of soldiers, but the general phrase adopted by them is milites classiarii, or socii navales.

Epignare (Fr.). A small piece of ordnance which does not exceed one pound in caliber.

Epigoni. A term which signifies “heirs” or “descendants.” It was applied to the sons of the seven chiefs who conducted an expedition against Thebes to restore Polynices, and who were all killed except Adrastus. Ten years later the Epigoni—namely, Alcmæon, Thersander, Diomedes, Ægialeus, Promachus, Sthenelus, and Euryalus—renewed the enterprise and took Thebes. The war of the Epigoni was celebrated by several ancient epic and dramatic poets.
