The 20 July plot, sometimes referred to as Operation Valkyrie, was a failed attempt to assassinate Adolf Hitler, the chancellor of Germany, and overthrow the Nazi regime on 20 July 1944. The plotters were part of the German resistance, mainly composed of Wehrmacht officers. The leader of the conspiracy, Claus von Stauffenberg, tried to kill Hitler by detonating an explosive hidden in a briefcase. However, due to the location of the bomb at the time of detonation, the blast only dealt Hitler minor injuries. The planners' subsequent coup attempt also failed and resulted in a purge of the Wehrmacht.
As early as 1938, German military officers had plotted to overthrow Hitler, but indecisive leadership and the pace of global events stymied action. Plotters gained a sense of urgency in 1943 after Germany lost the Battle of Stalingrad and Soviet forces began to push towards Germany. Under the leadership of Stauffenberg, plotters tried to assassinate Hitler at least five times in 1943 and 1944. With the Nazi secret police, the Gestapo, closing in on the plotters, a final attempt was organised in July 1944. Stauffenberg personally took a briefcase containing a block of plastic explosive to a conference in the Wolf's Lair. The explosives were armed and placed next to Hitler, but it appears they were moved unwittingly at the last moment behind a table leg by Heinz Brandt, inadvertently saving Hitler's life. When the bomb detonated, it killed Brandt and two others, while the rest of the room's occupants were injured, one of whom, Rudolf Schmundt, later died from his injuries. Hitler's trousers were singed by the blast, and he suffered a perforated eardrum and conjunctivitis, but was otherwise unharmed.
