North Korean sources claim that approximately 35,000 people were killed by American military forces and other supporters during the course of 52 days, which would have been about a quarter of the population of the county. Jack Willey of The Militant claimed that according to "Ri Song Jin, a witness to the massacre, imperialist forces tortured many Korean patriots in the basement of the Sinchon church at the beginning of the occupation, then buried the dead and near-dead bodies in a trench." The Sinchon Museum of American War Atrocities was established in 1958 and displays remains and belongings of those who are claimed to have been killed in the incident.
