Adolf Hitler killed himself by gunshot on 30 April 1945 in his Führerbunker in Berlin. His wife Eva Braun committed suicide with him by taking cyanide. That afternoon, in accordance with Hitler's prior instructions, 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. Records in the Soviet archives show that their burnt remains were recovered and interred in successive locations until 1970, when they were again exhumed, cremated, and the ashes scattered.
Accounts differ as to the cause of death; one states that he died by poison only and another that he died by a self-inflicted gunshot while biting down on a cyanide capsule. Contemporary historians have rejected these accounts as being either Soviet propaganda or an attempted compromise in order to reconcile the different conclusions. One eye-witness recorded that the body showed signs of having been shot through the mouth, but this has been proven unlikely. There is also controversy regarding the authenticity of skull and jaw fragments which were recovered. In 2009, American researchers performed DNA tests on a skull Soviet officials had long believed to be Hitler's. The tests and examination revealed that the skull was actually that of a woman less than 40 years old. The jaw fragments which had been recovered were not tested.
By early 1945, Germany's military situation was on the verge of total collapse. Poland had fallen to the advancing Soviet forces, who were, by then, preparing to cross the Oder between Küstrin and Frankfurt with the objective of capturing Berlin, 82 kilometres (51 mi) to the west. German forces had recently lost to the Allies in the Ardennes Offensive, with British and Canadian forces crossing the Rhine into the German industrial heartland of the Ruhr. American forces in the south had captured Lorraine and were advancing towards Mainz, Mannheim, and the Rhine. In Italy, German forces were withdrawing north, as they were pressed by the American and Commonwealth forces as part of the Spring Offensive to advance across the Po and into the foothills of the Alps. In parallel to the military actions, the Allies had met at Yalta between 4–11 February to discuss the conclusion of the war in Europe.
