Claus von Stauffenberg led an attempt to assassinate Adolf Hitler and overthrow the Nazi regime on July 20, 1944. The plot involved Operation Valkyrie, a contingency plan to maintain order in Germany. On July 20th, Stauffenberg planted a bomb in a briefcase near Hitler during a meeting at the Wolfsschanze headquarters. However, the bomb failed to kill Hitler when an officer moved the briefcase behind a table leg, shielding Hitler from the blast. Though some were killed, Hitler survived with only minor injuries. Stauffenberg and other conspirators were later arrested and executed after the failed coup.
