Svalbard [SEP] Second World War
However the Norwegian government in exile decided it would be important politically to establish a garrison in the islands, which was done in May 1942 during Operation Fritham. Meanwhile, the Germans responded to the destruction of the weather station by establishing a reporting station of their own, codenamed "Banso", in October 1941. This was chased away in November by a visit from four British warships, but later returned. A second station, "Knospel", was established at Ny Alesund in 1941, remaining until 1942. In May 1942, after the arrival of the Fritham force, the German unit at Banso was evacuated. In September 1943 in Operation Zitronella a German task force, which included the battleship "Tirpitz", was sent to attack the garrison and destroy the settlements at Longyearbyen and Barentsburg.
