Vàng tại Fort Yuma - Fort Yuma Gold (1966)

Near the end of the Civil War, an imprisoned Confederate raider is sent under guard to warn both his men and the Army at Fort Yuma that an impending rebel raid is really nothing but a ruse by scoundrels from both sides, in cahoots to take the fort's gold for themselves during the chaos. Soon he slips his treacherous escort and attempts to complete the mission himself.
