Bismarck 1941

On 22 June 1941 Germany invaded the Soviet Union, with Finland joining in a few days later. In the Arctic, German and Finnish forces crossed into northern Russia in an attempt to seize Murmansk but were slowed by the terrain and beaten back by a stubborn Soviet resistance. Thus, despite German advances almost everywhere else, the Soviet Union's only year-round ice-free Atlantic port remained open to shipments of Allied supplies.
