THE SEARCHERS. He even has a metal showing service in Maximillian’s army in Mexico.
Duke makes his entrance in The Searchers riding up wearing his gray Confederate overcoat. He refuses to take an oath when he's deputized because he'd 'already taken an oath to the Conferderate States of America'. He buries Lucy after wrapping her body in his 'Johnny Reb coat'. His character was a man who does not quite fit in, so it figures he'd be a rebel.
