Operation Zitronella, also known as Unternehmen Sizilien, was an eight-hour German raid on Spitzbergen, in the Svalbard Archipelago, on 8 September 1943. The battleships Tirpitz and Scharnhorst, plus nine destroyers, sailed to the archipelago, bombarded Allied-occupied settlements in Isfjorden and covered a landing party. Six Norwegians were killed and 31 were taken prisoner; sixteen Germans were wounded, one dying of his wounds.

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.
