Four Feather Falls S01E38 - Ambush

Red Scalp leads an Indian war party on a raid to ambush the train from Dallas and steal the $10,000 payroll on board, with the help of bank messenger William J. Haddon, who is apparently kidnapped during the raid to add some authenticity. But Red Scalp decides to double-cross Haddon and keep all the money for himself, until Tex recovers Haddon and the money.
