The first mass round up of Jews takes place in German-occupied Amsterdam. After a brief period of organized resistance by Jewish residents in the Jodenhoek (“Jewish Corner”) area of the city against escalating harassment by the military wing of the Dutch National Socialist Party, approximately 600 German members of the Ordnungspolizei (“Order Police”, or Orpo) armed with machine guns beat and arrested 389 men. They were subsequently transported to Buchenwald concentration camp, where many of them died. After four months, the survivors were then deported from Buchenwald to Mauthausen concentration camp. There, all but one died of torture, starvation and disease. Amsterdam, North Holland, Netherlands. 23 February 1941.
