Japanese officers then issued a written order: ALL PRISONERS OF WAR ARE TO BE EXECUTED. What followed was a six-week frenzy of killing that defies articulation. Masses of POWs were beheaded, machine-gunned, bayoneted, and burned alive. The Japanese turned on civilians, engaging in killing contests, raping tens of thousands of people, mutilating and crucifying them, and provoking dogs to maul them. Japanese soldiers took pictures of themselves posing alongside hacked-up bodies, severed heads, and women strapped down for rape.
