Purim
There is a tale in the Hasidic Chabad movement that supposedly Joseph Stalin died as a result of some metaphysical intervention of the seventh Chabad leader, Rabbi Menachem Mendel Schneerson, during the recitation of a discourse at a public Purim Farbrengen. Stalin was suddenly paralyzed on 1 March 1953, which corresponds to Purim 1953, and died 4 days later. Due to Stalin's death, nationwide pogroms against Jews throughout the Soviet Union were averted, as Stalin's infamous doctors' plot was halted.
Death of Adolf Hitler
General Hans Krebs met Soviet General Vasily Chuikov just prior to 04:00 on 1 May, giving him the news of Hitler's death, while attempting to negotiate a ceasefire and open "peace negotiations". Stalin was informed of Hitler's suicide around 04:05 Berlin time, thirteen hours after the event. He demanded unconditional surrender, which Krebs lacked authorisation to give. Stalin wanted confirmation that Hitler was dead and ordered the Red Army's SMERSH unit to find the corpse. In the early morning hours of 2 May, the Soviets captured the Reich Chancellery. Inside the "Führerbunker", General Krebs and General Wilhelm Burgdorf committed suicide by gunshot to the head.
