The July Plot
On July 20, 1944, Claus von Stauffenberg flew to the Wolf's Lair with Lt. Werner von Haeften. Stauffenberg carried a bomb in a briefcase and placed it on the floor next to Hitler and left to make a phone call.
The bomb exploded killing four men. Hitler survived the blast but his right arm was badly injured.
Stauffenberg returned to Berlin with Haeften and arrived at Army High Command Headquarters at 4:30 P.M. to launch a coup.
The plot unraveled, however, because Hitler survived the attack, co-conspirator General Friedrich Olbricht's neglected to set the coup in motion during first two hours after the attempt, and the conspirators' failed to seize any radio stations or retain authority over reserve army troops in Berlin.
On July 21, 1944, at 12:30 A.M., Stauffenberg was executed by firing squad. It was later reported that Stauffenberg died shouting. "Long live free Germany."
