 William F. Cody (qv) plays himself in the film, and recreates many  moments from his own involvement in the Indian Wars, including his  fight to the death with an Indian chief at Warbonnet Creek, which  occurred on July 10th, 1876. By the time of filming (1913), Cody was  much older and had gained a substantial amount of weight, but the  fact that such a legendary character played himself makes the film  immeasurably valuable.
