Festung Norwegen was the German term for the heavy defence and fortification system of Norway during the occupation of Norway by Nazi Germany in World War II. Some, including ReichskommissarJosef Terboven, thought that these fortifications would serve effectively as a last perimeter of defense of the Third Reich in the event of Allied victory on the continent. It turned out that they kept German troops away from mainland Europe and thus helped to end the war more quickly.
Considered an essential part of the Atlantic Wall in anticipation of an Allied invasion, the fortifications in Norway were primarily based around coastal artillery, but also included elements of anti-aircraft batteries, tank and infantry forces. There were as many as 400,000 German troops in Norway during the occupation, a large proportion of whom were dedicated to the defence of the Northern flank of the Atlantic wall. The scope of Festung Norwegen originally included the entire coastal perimeter of Norway, from the Oslofjord around the southern coast and to the border with the Soviet Union. Part of the invasion plan for Norway included the immediate deployment of German coastal artillerymen in Norwegian batteries, around the main cities of Horten, Kristiansand, Stavanger, Bergen, Trondheim, and Narvik.
Coastal batteries
An extensive network of coastal artillery batteries with heavy, medium and light ordnance was set up around the entire coast. These were typically placed so as to cover the approaches to main population centres and likely landing sites. The batteries were also generously equipped with close combat weapons, such as machine guns and small arms. By the end of the war, there were 221 batteries along the coast, under either Kriegsmarine or Heer command. There were also anti-aircraft artillery batteries in Kristiansand, Bergen, Trondheim, Bogen, and Harstad; these were armed with 88-mm pieces. The tanks available for the German defense were Panzer IIIs and Sturmgeschütz IIIs. Fjell fortress with its triple barrel 28 cm SK C/34 naval gun turret, taken from the battleship Gneisenau, was seen as one of the strongest fortresses in Northern Europe.
Aftermath
The war ended without any of the fortifications being used in action. The fortress kept German troops away from the main battles on mainland Europe and thus helped to bring the war to a quicker end. The British Operation Fortitude North was designed to delude the Germans that they intended to invade Norway in 1944, as well as the Pas de Calais, so as to keep their troops away from the Normandy beaches.
