Content:  On 30 April 1945, Adolf Hitler killed himself in his Führerbunker, under the Reich Chancellery, having drawn up a testament in which Admiral Karl Dönitz succeeded him as Head of State, with the title of Reich President. But with the fall of Berlin two days later, and American and Soviet forces having linked up at Torgau on the Elbe, the area of Germany still under German military control had been split in two. Moreover, the speed of the final Allied advances of March 1945 – together with Hitler's insistent orders to stand and fight to the last – had left the bulk of surviving German 
Title: Death of Adolf Hitler
Content:   Adolf Hitler, the Austrian-born German politician who was the leader of the Nazi Party, Chancellor of Germany from 1933 to 1945, and Führer ('Leader') of Nazi Germany from 1934 to 1945, committed suicide by gunshot on 30 April 1945 in his Führerbunker in Berlin. Eva Braun, his wife of one day, committed suicide with him by taking cyanide. In accordance with his prior written and verbal instructions, that afternoon their remains were carried up the stairs through the bunker's emergency exit, doused in petrol, and set alight in the Reich Chancellery garden outside the bunker. Although records in the Soviet archives indicate that the burned remains of Hitler and Braun were recovered and interred in successive locations until 1946, and that they

In late April 1945, Stockholm's "Free German Press Service" circulated a rumor that a Hitler double named August Wilhelm Bartholdy, supposedly a former grocer from Plauen, was called to Berlin to be filmed dying on the battlefield in Hitler's stead. The Germans émigrés stated, "He will act as Hitler's trump card, creating a hero legend around the Führer's death, while Hitler himself goes underground." Hitler died in Berlin on 30 April, with his dental remains subsequently being positively identified. On 9 May 1945,

On the afternoon of 30 April, about a day and a half after he signed his last will and testament, Hitler and Braun committed suicide. Within the next two days, Goebbels, Burgdorf and Krebs also committed suicide. Bormann's fate was unknown for decades, but his remains positively identified in 1998 indicated that he died fleeing on 2 May 1945 to avoid capture by the Soviet Red Army forces encircling Berlin.
Title: Last will and testament of Adolf Hitler
Content:  All four witnesses to the political testament died shortly afterwards. Goebbels and his wife committed suicide. Burgdorf and Krebs committed suicide together on the night of 1/2 May in the bunker. Bormann's exact time and place of death remain uncertain; his remains were discovered near the site of the bunker in 1972 and identified by DNA analysis in 1998. He probably died the same night trying to escape from the Führerbunker. In the Flensburg Government of Hitler's appointed successor as Reichspräsident Karl Dönitz, the depositions of Albert Speer and Franz Seldte were ignored (or the two ministers quickly reinstated). Neither former incumbent Joachim von Ribbentrop nor Hitler's appointee, Seyß-Inquart, held the post of Foreign Minister. The post was given to Lutz Graf Schwerin von Krosigk, who after Goebbels' suicide also became Leading Minister of the German Reich (Head of Cabinet, post equivalent to Chancellor).

Content:  After Hitler's death on 30 April, Högl, Ewald Lindloff, Hans Reisser, and Heinz Linge carried his corpse up the stairs to ground level and through the bunker's emergency exit to the bombed-out garden behind the Reich Chancellery. There, Högl and the others witnessed the cremation of Hitler and Eva Braun. On the following night of 1 May, Högl joined Rattenhuber in his attempt to break-out from the Soviet Red Army encirclement. After midnight on 2 May 1945, he was wounded in the head while crossing the Weidendammer Bridge and died of his injuries. Högl was 47 years old.

In 2009, Russian General Vasily Khristoforov, the head archivist of Russia's Federal Security Service, claimed that KGB agents under the orders of Soviet Premier Yuri Andropov burned Hitler's remains and dumped them into a German river. According to the documents Khristoforov referenced, "The remains were burnt on a bonfire outside the town of Shoenebeck, 11 kilometers away from Magdeburg, then ground into ashes, collected and thrown into the Biederitz River." Khristoforov claimed that Andropov feared that Hitler's burial site would become a place frequented by neo-Nazis.
