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.
