During the period of 1939-1945, Finland fought 3 wars with the Soviet Union. During the longest of those wars, the Continuation War from 1941–1944, Soviet prisoners of war were either kept in camps or put to work in factories or mines. Some were even sent to work on family farms in Finland, which were suffering from a lack of work force due to the large number of men off fighting in the war. Certain prisoners, classified as ‘clan’ soldiers because they were of a nationality that was related to Finland and Finnish, were given special treatment and better chances of being sent to farms. Officially the farm workers were to be treated like prisoners, sleeping behind locked doors and being given strictly rationed food. However, some were treated the same as other farm workers. When the war ended in 1944, all prisoners of war had to be sent back to the Soviet Union.
