In the beginning of World War II, the island was occupied by the German Army. In December 1941, it was the venue of the Operation Anklet – a British Commando raid carried out by 300 men from No. 12 Commando and the Norwegian Independent Company 1. The landing party was supported by 22 ships from three navies – British, Norwegian and Polish. As a result, two German radio transmitters were destroyed and several small boats were captured or sunk. Importantly an operational Enigma coding machine was obtained from one of the sunken German patrol ships. Also, about 200 local Norwegians volunteered to serve in the Free Norwegian Forces.
