Dutch resistance
Dutch social democrats, Catholics, and communists started the resistance movement.  At first, if the Germans discovered people were involved in the resistance, they put them in jail.  However, if a person was a member of an armed or military group, the Nazis could send them to concentration camps. After mid-1944, Hitler ordered his soldiers to shoot all resistance members. The Nazis also did revenge attacks against civilians, where they killed innocent civilians after resistance activities happened.
