Smiling as he inspected the young troops and seemingly without a care in the world, Adolf Hitler must have been as skilled an actor as he was a tyrannical dictator. By the date of this picture - April 28th, 1945 - Hitler knew that the war was coming to an end, and that he was going to lose it. He'd gone out into the city to inspect bomb damage and try to raise the morale of citizens. It may have worked on them, but there would be no salvation for his own morale.
Having been betrayed and abandoned by his own generals and pincered by the Allies on one side and the Russians on the other, Hitler was trapped like a rat with nowhere to go. He finished his tour of the city, sealed himself in his bunker for two days and tried to think of any way out of the situation. He eventually found one - suicide to avoid being captured.
