:''For the prehistoric biological event, see Grande Coupure'' A coupure is a means of closing an opening in a wall, floodwall or levee (dike). The word comes from the french verb ''couper'' which means to cut. In historic times a coupure was a location where a breach in the city walls or the walls of a fortress was closed. In more modern times a coupure is a way of allowing traffic to pass a flood protection structure. ==Military== During a siege a coupure is a ditch or an earthwork or wooden palisade built behind a breach in the walls of a fortress, or a city, made by the attacker's guns. Its purpose is to hinder and frustrate an attack made by the forlorn hope. This was a strategy used many times by defenders of fortifications, for example, by the Irish defenders during the Siege of Clonmel (April - May 1650). It can also be a passage through a glacis to create a sally port so that the defenders can launch a sortie against the attackers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coupure」の詳細全文を読む スポンサード リンク
