Norwegian armed forces in exile

The Norwegian armed forces in exile (Norwegian: Utefronten, lit. 'Outside Front') were remnants of the armed forces of Norway that continued to fight the Axis powers from Allied countries, such as Britain and Canada, after they had escaped the German conquest of Norway during World War II. == Background == Norway was neutral in World War I and tried to remain neutral in World War II. Neutrality was maintained until the German invasion began on 9 April 1940. Norwegian coastal artillery sufficiently delayed the German capture of Oslo to permit Norway's King Haakon VII, the royal family and the government to flee the capital and eventually reach Tromsø at the top of Norway on 2 May.
