General der Gebirgstruppe Eduard Dietl (Kommandierender General Gebirgskorps Norwegen) with German and Finnish officers in the northern Russian tundra, July 1941. In 29 June 1941, Dietl was placed in command of Operation Silver Fox (Unternehmen Silberfuchs), a joint German–Finnish military operation plan during World War II, though it was mainly operated and engaged by Germans. Its main goal was the capture of the key Soviet port at Murmansk through attacks from Finnish and Norwegian territory. The operation had three stages. Operation Reindeer (Rentier) was the initial attack by German forces from Norway to secure the area around Petsamo. The follow-up operations, Operation Platinum Fox (Platinfuchs) from the north by Army Norway (AOK Norwegen) and Operation Arctic Fox (Polarfuchs) by XXXVI Mountain Corps together with units from the Finnish III Corps, aimed to capture the vital port of Murmansk afterwards. The operation was unsuccessful and Murmansk continued to operate throughout the war.
