Major Dundee was a 1965 Western film written by Harry Julian Fink and directed by Sam Peckinpah. It starred Charlton Heston and Richard Harris as officers from opposing sides in the American Civil War who band together to hunt down a band of Apaches.
It has become notorious for the feud between Peckinpah and the producing studio, Columbia Pictures, during its production and editing.
During the American Civil War, Union cavalry officer Major Dundee (Heston) is relieved of his combat command for an unspecified tactical error at the Battle of Gettysburg and sent to head a prisoner-of-war camp in the New Mexico Territory. After a family of ranchers and a relief column of cavalry are massacred by an Apache war chief named Sierra Charriba (Michael Pate), Dundee seizes the opportunity for glory, raising his own private army of Union troops (black and white), Confederate POWs led by his old friend and rival (from their days together at West Point), Captain Tyreen (Richard Harris), several Indian scouts, and a gang of civilian mercenaries to illegally pursue Charriba into Mexico. Tyreen bears a personal grudge against Dundee. Before the war, Dundee cast the deciding vote in Tyreen's court-martial from the U.S. Army for participating in a duel. However, having given his word of honor, the chivalrous Tyreen binds himself and his men to serve loyally, but only until Charriba has been dispatched.
