Fort Apache is a 1948 American Western film directed by John Ford and starring John Wayne and Henry Fonda. The film was the first of the director's "Cavalry Trilogy" and was followed by She Wore a Yellow Ribbon (1949) and Rio Grande (1950), both also starring Wayne. The screenplay was inspired by James Warner Bellah's short story "Massacre" (1947). The historical sources for "Massacre" have been attributed both to George Armstrong Custer and the Battle of Little Bighorn and to the Fetterman Fight.
