What now actually became of Hitler's body? To what extent was it burned? Did the Russians find anything resembling a corpse? The burning of a corpse in the open is not of course comparable to a cremation in a crematorium, and not even to the burning of a body or parts of a body in a stove such as occurs from time to time in criminal cases.
During a cremation, the enveloping heat reflected from the walls of the oven leads to the intensive destruction of organic matter. If a corpse is burned in the open, as was the case with Hitler and Eva Braun-Hitler, the distribution of heat varies and consequently so does the depth of destruction, besides which much heat is lost by radiation into the atmosphere. When a human body is burned in the open by means of petrol, the first thing that burns off is the extraneous petrol, which causes a strong heating up of the corpse. Then, because they act like a wick, the fire spreads to the clothes, which burn away more or less quickly depending on the nature and structure of the fabric.
When the open flames then act directly on the body surface for a longer period of time, the final result is carbonization. During the process, steam forms in the subcutaneous tissue and in the course of the burning the pressure can rise dramatically, so that the body surface bursts open in many places, like an overheated frozen burrito. The skull can also burst from the same effect. The heat causes the protein in the cells of the muscles to congeal, which then contract. This leads to contortions of the arms or the lifting up and contracting of the upper body and legs, which stay in this position because of posthumous heat rigor mortis, which is called the "fencer's stance."
The heat causes the body fat to melt and the fatty acids released to run out of the gashes in the skin. Because of the major loss of water and fat, the carbonated corpse or torso shrinks to a substantial degree. If the burning continues for an extended period of time, the soft tissue is almost completely consumed. The only thing remains is fragile, calcified bones that can easily disintegrate even without external force being applied.
As a result, it is very unlikely that anything resembling a human corpse remained following Adolf Hitler's post-mortem burning.
According to Gunsche, "That Adolf Hitler was not completely burnt up with the help of the petrol is correct. The remains were scattered and shell fire did the rest... The heavy artillery and napalm fire went on until 2 May. Nothing was left that could point to Hitler... Often I can only shake my head about the claims of so-called witnesses, some of whom were not even there and are only repeating hearsay from others as their own observations. Maybe such claims, which were made immediately after the end of the war and have been repeated in various versions, are the answer to the fact that no one was in a position to prove what was left of the Fuhrer's corpse and where this could be seen. None of the reports about this can be proved: they are falsification... The destruction of the Fuhrer's corpse and that of his wife was complete through various causes."
Therefore, it is most likely nonsense that the Russians, as they claimed several weeks after his death, ever found Hitler's body/corpse. To this day the Russians have not presented a single piece of evidence that they found Hitler's corpse. Where are the authentic photographs? Where is the allegedly lead-lined box with Hitler's identifiable corpse? Why was this not shown to the German witnesses the Russians had captured? Even though in 1945--and during their reconstruction of the events in 1946--the Russians kept telling Linge, Gunsche, Baur, Hofbeck, Henschel and the others that they would be "confronted with Hitler's body," they never showed it to any of these people.
Flugkapitan Hans Baur said on November 24, 1995, "...After we arrived in Berlin, I was interrogated by a Commissar I already knew called Krause (Klausen), who had come with us from Moscow. This Commissar held the rank of Lieutenant-Colonel . He told me that it was now high time to decide what to do with the corpses. We would be shown the bodies and should say whether we recognized any features which could indicate the identity of Hitler or Eva Braun. Up to now the bodies had been preserved. It was now time to decide if this should remain so or whether they should be destroyed. A confrontation with the corpses did not take place, however..."
The only person who claimed to have seen Hitler's corpse is Harry Mengershausen. He recalled that, in early June 1945, an inspection of "the place" where Hitler's corpse had allegedly been buried took place. The crater had been dug up. We must remember that the garden of the Chancellory and the area around the bunker was a huge field of craters. That Mengershausen spoke of a specific crater is already an indication that he was lying. Mengershausen goes on to say that in early July he was taken from the prison in Friedrichshagen to an open pit in woods nearby in order to identify three corpses. Each of the corpses was by itself in a "small wooden casket." The corpses had been those of Hitler and Herr and Frau Goebbels. Mengershausen claims to have "clearly recognized" Hitler by the shape of the head, the distinctive shape of the nose and the missing feet. "From the distance" he had not been able to see if Hitler's jaw had still been there. The whole "viewing of the bodies" had lasted for less than two minutes.
Once again, Mengershausen is telling a story--in great detail as usual--that simply does not fit the circumstances. It is impossible that Mengershausen was able to detect the "distinctive shape of Hitler's nose." The nose, like all the other soft tissues of the face, the torso and the extremities, must surely have burned away during the relatively long cremation process. A skull that is exposed to strong heat can preserve its bony shape for quite some time, but not its distinctive features, which it takes from the soft tissue of the face.
There was another witness available in 1945, who had been as closely involved in the final phase of the destruction of Adolf Hitler's and Eva Braun's bodies as Harry Mengershausen, if not more closely. This witness was Hermann Karnau who was a prisoner of the British. On November 13, 1953, Karnau recounted, "In November 1945 I was taken from Esterwegwn to Berlin. Here I was told by an officer of the Secret Service that I was to lend a hand in the local search for Hitler's remains. However, this did not take place because of the refusal of the Russians."
