This Nazi propaganda film was deemed lost until 2006 when Norwegian film historian Jostein Saakvitne was able to buy the film on a German Internet auction platform. Kampf um Norwegen is a German invasion film that Dr. Martin Rikli was asked to make by the Oberkommando der Wemacth. Kampf um Norwegen was never shown in Germany, and nobody knows the reason why. Until 2006 the film was believed lost in the bombing of Berlin. The film describes the tactical part of the invasion of Norway, and how Germany fought against both Norwegian and British forces in a difficult and unknown terrain. Even though this is a propaganda film, it is only made by facts from the invasion, and has therefore got a tremendous historical value. This film is recommended to all those who are interested in WWII and military strategies.
