Operation Zitronella (Operation Lemon Flavour), also known as (Operation Sicily), was an eight-hour German raid on Spitzbergen, in the Svalbard Archipelago, on 8 September 1943. The battleships (in its only offensive action) and , 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. Background Svalbard The Svalbard Archipelago is in the Arctic Ocean, from the North Pole and a similar distance to Norway to the south. The islands are mountainous, with permanently snow-covered peaks, some glaciated; there are occasional river terraces at the bottom of steep valleys and some coastal plains. In winter, the islands are covered in snow and the bays ice over. To the west, Spitzbergen Island has several large fiords along its west coast; Isfjorden being up to wide. The Gulf Stream warms the waters and the sea is ice-free during the summer. In the 1940s, there were settlements at Longyearbyen (Longyear Town) and Barentsburg, in inlets along the south shore of Isfjorden, in Kings Bay (Quade Hock) further north along the coast and in Van Mijenfjorden to the south. The settlements attracted colonists from many places; the treaty of 1920 neutralised the islands and recognised the mineral and fishing rights of the participating countries. Before 1939, the population consisted of about mostly Norwegian and Soviet workers in the mining industry. Drift mines were linked to the shore by overhead cable tracks or rails and coal dumped over the winter was collected by ship after the summer thaw. By 1939 production was about a year, split between Norway and the USSR. Second World War During the Second World War, the Svalbard Archipelago was the scene of several military operations. In August 1941, British, Canadian and Free Norwegian Forces landed on Spitzbergen during Operation Gauntlet to destroy the coal industry, associated equipment and stores. No attempt was made to establish a garrison and the civilian population was evacuated. Nazi Germany set up manned meteorological stations in the Arctic to improve weather forecasts, vital for the warfare against Allied convoys from the UK to the USSR. Dr Erich Etienne, a former Polar explorer, commanded an operation to install a manned station on the islands. Advent Bay (Adventfjorden) was chosen for its broad valley, a safer approach and landing ground for aircraft. The subsoil
