King Richard I Lionheart (1157-1199) watches Muslim prisoners being beheaded after the capture of Acre in 1189. When it became apparent that Saladin was not willing to pay the terms of the treaty at Acre, Richard had more than 3.000 Muslim prisoners executed on August 20 outside of Acre in full view of Saladin's camp.
