During WWI a British Soldier had Hitler in his sites, but didn't pull the trigger

During the battle of  Marcoing, Henry Tandey, a British soldier and later a recipient of the Victoria Cross, had a wounded German soldier walk through his line of fire, the wounded soldier made no attempt to raise his rifle, so Tandey opted not to take the shot. The German soldier saw Tandey lower his rifle and nodded his thanks before wandering off. The soldier was later identified as Lance Corporal Adolf Hitler.
