Lapland War
The Lapland War (Finnish: Lapin sota; Swedish: Lapplandskriget; German: Lapplandkrieg) was fought between Finland and Germany from September 1944 to April 1945 in Finland's northernmost Lapland Province. While the Finns saw this as a separate conflict, much like the Continuation War, German forces considered their actions to be part of the Second World War. A peculiarity of the war was that the Finnish Army was forced to demobilise their forces while at the same time fighting to force the German Army to leave Finland. German forces retreated to Norway, and Finland managed to uphold its obligations under the Moscow Armistice, although it remained formally at war with the Soviet Union, the United Kingdom and the British Dominions until the formal conclusion of the Continuation War was ratified by the 1947 Paris Peace Treaty.
Prelude
Germany and Finland had been at war with the Soviet Union since June 1941, co-operating closely in the Continuation War. However, as early as the summer of 1943, the German High Command began making plans for the eventuality that Finland might make a separate peace agreement with the Soviet Union. The Germans planned to withdraw their forces northward in order to shield the nickel mines near Petsamo.
