How did Adolf Hitler die?
ON 30 April 1945, Adolf Hitler arranged to marry Eva Braun in the Fuehrer Bunker in the center of Berlin. The marriage register and licence still exist BTW. After a reception, later that evening after saying goodbye to his staff, they retired to his room, with his military aide guarding the door. After about 20 minutes, Magda Goebbels demanded entrance-and begged Hitler to leave for Berchtesgaden (in the south). [Magda Goebbels was definitely in love with Hitler, and while sources are silent, there’s enough circumstantial evidence that I believe she might have offered sexual favors to him a few years earlier; in order to get back at her husband. Who was noted even by the pervs in the Nazi hierarchy as a womanizer.] Anyway, if Hitler left, she would not have to kill her children; which was primarily the reason for her hysterical pleas. After she left, the guard heard two shots and a thud. He waited about 10 minutes, then opened the door.
Excerpts from Wikipedia After intense street-to-street combat, when Soviet troops were spotted within a block or two of the Reich Chancellory in the city centre, Hitler committed suicide in the Führerbunker on April 30, 1945 by means of a self-delivered shot to the head (it is likely he simultaneously bit into a cyanide ampoule). Hitler’s body and that of Eva Braun (his long-term mistress whom he had married the day before) were put in a bomb crater, partially burned with gasoline by Führerbunker aides and hastily buried in the Chancellory garden as Russian shells poured down and Red Army infantry continued to advance only two or three hundred metres away. He also had his dog Blondi poisoned around the same time.
