This story is based upon the real 1944 Hitler assassination attempt. In July 1944, Colonel Claus Schenk Graf von Stauffenberg carried a briefcase loaded with explosives into a staff meeting. The bomb went off, but Hitler was only injured because the heavy oak conference table shielded him from the blast. Von Stauffenberg was quickly arrested and then executed.
