Operation Haudegen was the name of a German operation during the Second World War to establish meteorological stations on the Svalbard archipelago in Norway. In September 1944, the submarine U-307 and the supply ship Carl J. Busch transported the men of Unternehmen Haudegen to the island. The station was active from 9 September 1944. On May 8, 1945, the staff received a message from their commanders in Tromsø that Germany had surrendered and the war was over. After that, radio contact was lost. The soldiers were capable of asking for support only in August 1945 and on 6 September, were picked up by a Norwegian seal hunting vessel and surrendered to its captain. The group of men were the last German troops to surrender after the Second World War.

Svalbard, previously known as Spitsbergen or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it lies about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed in size by Nordaustlandet and Edgeøya. The largest settlement is Longyearbyen on the west coast of Spitsbergen.
