A week later, on 21 March, Army Group Centre organised a display of Russian Army flags and weapons seized at the Eastern Front. It was exhibited at Zeughaus, military museum in Berlin, which Hitler was to visit on Heroes' Memorial Day with Himmler and Hermann Göring. Colonel Gersdorff volunteered to be the suicide bomber, intending to explode a bomb on his person near Hitler while serving as a tour guide. He had with him bombs with ten-minute fuses, knowing that Hitler was scheduled to be in the museum for 30 minutes. But at the last minute, just before Hitler was to arrive, the duration of his stay was reduced to just eight minutes as a security precaution. Hitler breezed through in two minutes. As a result, Gersdorff could not accomplish his mission, the assassination plan failed again and he barely managed to get out and defuse the bombs.
