Just over 3,000 Danes died as a direct result of the occupation. (A further 4,000 Danish volunteers died fighting in the German army on the Eastern Front). Overall this represents a very low mortality rate (ca. 0.08% of population) when compared to other occupied countries and most belligerent countries. (See: World War II casualties). An effective resistance movement developed by the end of the war, and most Danish Jews were rescued in 1943 when German authorities ordered their internment as part of the Holocaust.
