The incident on Hill 192 refers to the kidnapping, gang rape, and murder of Phan Thi Mao, a young Vietnamese woman,[1] on November 19, 1966[2] by an American squad during the Vietnam War.[1] Although news of the incident reached the U.S. shortly after the soldiers' trials,[3] the story gained widespread notoriety through Daniel Lang's 1969 article for The New Yorker[4] and his subsequent book.[5] In 1970, Michael Verhoeven made the film o.k., based on the incident. The Visitors is a 1972 American drama film directed by Elia Kazan also based on the incident. In 1989, Brian De Palma directed the film Casualties of War, which was based on Lang's book.[1]
