Norwegian partner of the occupying Germans was the fascist Quisling regime, in one form or another. The Royal Norwegian Navy and Royal Norwegian Air Force (RNoAF) were re-established in Britain – based on the remnants of forces saved from the Norwegian Campaign. The forces soon saw extensive combat in the convoy-battles of the North Atlantic and in the air-war over Europe. The ranks of the Navy and Air Force were swollen by a steady trickle of refugees making their way out of occupied Norway, and their equipment brought up to standard by British and American aircraft and ships. From a force of 15 ships in June 1940, the Royal Norwegian Navy had expanded to 58 warships by the end of the Second World War in Europe. The ships were manned by around 7,000 crew members. In all 118 warships had been under Norwegian command at one time or another during the war years. Norwegian squadrons flew with the RAF Fighter and Coastal Commands. The Norwegian-manned 331 Squadron and 332 Squadron operated Hawker Hurricane and Supermarine Spitfire fighter aircraft. The naval 330 Squadron and 333 Squadron flew Northrop N-3PB patrol bombers, Consolidated PBY Catalina and Short Sunderland flying boats and de Havilland Mosquito fighter bombers. Individual Norwegians flew with British air units. In November 1944 the Royal Norwegian Naval Air Service and the Norwegian Army Air Service, having been under a unified command since March 1941, were amalgamated to form the RNoAF. At the end of the war some 2,700 personnel served in the RNoAF. A c. 4,000 strong Norwegian Army was also re-established in Scotland. However, with the exception of a small number of special forces, it saw little action for the rest of the war. A reinforced company from the Scotland-based Norwegian Army participated in the liberation of Finnmark during the winter of 1944–45. Finnmark and the northern parts of Troms county had been forcibly evacuated by the Germans in a scorched earth operation following the Petsamo–Kirkenes Offensive by the Red Army against occupied Finnmark in October 1944. The offensive had captured the north-eastern town of Kirkenes from the occupying German forces. After the arrival of the 300 troops from Scotland, further troops were moved in from Sweden and mobilized locally. At the end of the war, the Norwegian forces in Finnmark totalled 3,000. In the course of this operation, there were some minor skirmishes with German rear guards
