You Can't Win 'Em All (1970)

Two former U.S. Army soldiers, Adam Dyer and Josh Corey, join a band of Turkish mercenaries in 1922 Turkey. They are hired by Osman Bey, a local governor, to escort his three daughters to Smyran and to protect a gold shipment that is to accompany them. Nobody is aware that Elci, a local colonel, plans to steal the gold for himself, while a rebel general pursues all parties involved.
