Carl Gustav Fleischer KCB (28 December 1883 – 19 December 1942) was a Norwegian general and the first land commander to win a major victory against the Germans in the Second World War. Having followed the Norwegian government into exile at the end of the Norwegian Campaign, Fleischer committed suicide after being bypassed for appointment as commander-in-chief of the Norwegian Armed Forces in exile and being sent to the insignificant post as commander of Norwegian forces in Canada.
