Reinhard Heydrich was one of the main architects of the Holocaust, answering directly to Hitler. Heydrich chaired the infamous Wandsee conference, which approved the deportation of the Jews to extermination camps. He became "Protector" of the occupied Czech territories of Moravia and Bohemia, which he ran with a rule of iron. In London, the Czechoslovak government in exile was encouraged to plot the assassination of Heydrich by the British Government. They realized that his death would lead to retaliation - but both the British and the Czechs judged that the price was worth paying. On May 27, 1942, Heydrich was ambushed while he rode in his open car in the Prague suburb of Kobylisy. Heydrich died on June 4, 1942 of septicemia, from injuries he suffered in the ambush bombing.
