The Man from Colorado

In Colorado at the end of the Civil War, Col. Owen Devereaux (Glenn Ford), affected by four years of brutal bloodshed, orders the massacre of a Confederate unit, even as they try to surrender. Devereaux's friend and second in command, Capt. Del Stewart (William Holden), is the only one aware of the surrender attempt. Devereaux returns home to a hero's welcome and is appointed a judge, yet his irrational and angry behavior continues, affecting his fianceé, Caroline (Ellen Drew), as well as Del.
