Crisbecq Battery

The Crisbecq Battery was a German World War II artillery battery constructed by the Todt Organization near the French village of Saint-Marcouf in the department of Manche in the north-east of Cotentin peninsula in Normandy. It formed a part of Nazi Germany's Atlantic Wall coastal fortifications. The main armament were three Czech 21 cm Kanone 39 canons, two of which housed in heavily fortified casemates up to 10 feet thick of concrete. The battery, with a range of 27–33 kilometers, could cover the beaches between Saint-Vaast-la-Hougue and Pointe du Hoc.

The battery engaged US ships on D-Day and was evacuated by the Germans on 11 June 1944 and took no further part in the Normandy landings.
