In the early hours of 19 April 1943, German military and police units entered the Warsaw Ghetto, acting on orders from Heinrich Himmler to carry out the final liquidation of the Jewish residential district in Warsaw. On that day, the Jews trapped behind the walls took up arms. The resolute resistance put up that day by soldiers from the Jewish Combat Organisation and the Jewish Military Union, which launched the Warsaw Ghetto Uprising 83 years ago, was one of the greatest acts of resistance mounted by Jews against the Third Reich.
