Mont Canisy battery

The Mont Canisy battery was a World War II German artillery battery constructed close to the French village of Benerville-sur-Mer in the Calvados department in the Basse-Normandie region. Located on the highest ground in Normandy (110 m high), the vantage point overlooks the Côte Fleurie. The bunker complex was constructed between 1941 and 1944 to protect the River Seine estuary and the port of Le Havre. It was the largest artillery bunker complex between Cherbourg and Le Havre. The battery is 8 km west of the Houlgate battery.

A French naval coastal battery was originally built on the site in 1937. During the advance of German troops in 1940 the guns were put out of action before the site was captured in 1940.

Much of the site is now a nature reserve and the bunker complex is open to the public and guided tours take place throughout the summer.

French battery
In late 1938 the French army installed four 138mm cannons at the battery and in January 1940 three 75mm guns were added. The battery was evacuated on 14 June, 1940 and the German army later occupied the strategic position.

Construction
The Germans built the twenty-five hectare bunker complex (designated Widerstandsnest WN Vill 013 (resistance nest or strongpoint) in 1942 to house six captured French First World War-vintage 155mm cannons. In January 1944, two casemates were constructed to protect two artillery pieces from Allied bombing of the site. The complex featured several casemates, 25 ammunition bunkers, 25 barracks, defensive mortar pits and Tobruks fitted with machine guns and a post fire control bunker all linked by 250 metres of underground tunnels.

Garrison
The battery was garrisoned by the 2nd Company of the 1255 Heeres-Küsten-Artillerie-Abteilung (HKAA).

D-Day and Normandy landings
By the time of the Normandy landing in June 1944, only four cannons remained, two is casemates. On D-Day, 6 June 1944, HMS Warspite (03), HMS Ramillies (07) and HMS Roberts engaged the bunker complex at Mont Canisy. However, the German guns could not reach the warships and it was determined that they were not a threat to the landing beach at Sword either (24 km distant). As the Allies advanced out of Normandy, the Germans evacuated the bunker complex on 21 August 1944 without a fight.
