Executioner
'Colter's Run'. Cornel Wilde's movie The Naked Prey (1965) was a story based on this event, but the movie scene was set in Africa.
Actually, I think "Run of the Arrow" (1957) with Rod Steiger and Brian Keith was probably closer, since it portrayed a Confederate veteran who was adopted by the Sioux after surviving the run of the arrow. A warrior shot an arrow and the prisoners would walk to where the arrow landed and then start running, with the Sioux running after them.
