13 Minutes — Germany
Cabinet-maker Georg Elser plants a bomb in the Bürgerbräukeller to kill Hitler on 8 November 1939 — but Hitler leaves 13 minutes before the explosion, and Elser is caught at the Swiss border.
Georg Elser acted entirely alone over 30 nights, tunnelling into the Bürgerbräukeller's pillar. Hitler left early due to fog grounding his aircraft. The blast killed 8 people, injured 62. Elser was kept alive as a 'special prisoner' for a possible show trial that never happened, and was murdered at Dachau on 9 April 1945, three weeks before liberation — on the Gestapo's explicit order.
