Olav made several visits to Norwegian and Allied troops in the United Kingdom, Canada and the United States. In 1944, he was appointed to the post of Norwegian Chief of Defence and after the war he led the Norwegian disarmament of the German occupying forces. On 13 May 1945 Crown Prince Olav and five government ministers returned to a liberated Norway. His war decorations from other nations, including the War Crosses of Norway, France, Greece and the Netherlands, the US Legion of Merit and the French Médaille Militaire, are testament to the international recognition of his contribution to the war against Hitler.
