TO GO WITH AFP STORY by JEAN-LOUIS DE LA VAISSIERE - FILES - This undated handout picture shows a portrait of German member of the resistance Count Claus Graf Schenk von Stauffenberg. Born into an aristocratic family, von Stauffenberg was an army officer during the war but grew disillusioned with the Nazis. Von Stauffenberg planted a briefcase bomb during a staff meeting with Hitler on 20 July 1944. Though the bomb went off, Hitler was not killed. Von Stauffenberg escaped the blast but was captured and executed the same day. The assassination attempt of 20 July 1944 marked the end of many years of efforts by top administrative officials and members of the military to change the course of the war from the centre of power by putting an end to Hitler's leadership.
