Following the German occupation of Norway in April 1940, Milorg was formed in May 1941 as a way of organizing the various groups that wanted to participate in an internal military resistance. At first, Milorg was not well coordinated with the Special Operations Executive (SOE), the British organization to plan and lead resistance in occupied countries. In November 1941 the Milorg became integrated with the High Command of the Norwegian government in exile in London, answering to the British Army's Department British Field Office IV, which dealt with sabotage operations, but Milorg's British counterpart, SOE, was still operating independently. This lack of coordination led to a number of tragic incidents, creating bitterness within Milorg. SOE changed its policy at the end of 1942, and from then on Milorg and SOE efforts were coordinated.
