Thirty critically wounded U.S. troops were stranded at the top of a mountain. Attended to by only two non-combatants, a chaplain and a medic, the wounded were discovered by a North Korean patrol. Though the medic was able to escape, the North Koreans executed the unarmed chaplain as he prayed over the wounded, then killed the rest of them. The massacre was one of several incidents that led U.S. commanders to establish a commission in July to look into war crimes during the war.
Jo was dispatched by the Soviet authorities to liberated Korea when the Red Armyentered in 1945. By that time, he had much experience of Soviet literature and literature administration. The Soviets hoped that Jo would shape the cultural institutions of the new state based on the Soviet model. For the Soviets, the move was successful and Jo did not only that but also significantly developed socialist realism as it would become the driving force of North Korean literature and arts.
Jo offered some of the earliest contributions to Kim Il-sung's cult of personality. His most famous work is Mt. Paketu (1947), a lyrical epic praising Kim Il-sung's guerrilla activities and promoting him as a suitable leader for the new North Korean state.
