 Saboteurs were active in Central Norway in late 1944 and early 1945, with sabotages against the Nordland Line, the Dovre Line and the Rauma Line in addition to the Røros Line.This was of high strategic importance, as German forces were retreating from Northern Norway, using the rail roads for troop transport.Although the war was going against Germany at the time, there were rumours that they would not leave Norway without an Allied invasion, thus, pockets of Norwegian resistance forces were prepared for warfare.
