The film packs thrills , fights , noisy action , crossfire , Indian charges , including Sioux habits with their rites and ceremonies and being enough entertaining .

It contains an atmospheric and adequate musical score , as well as faded and tarnished cinematography Henry Freulich with a very bad print , being utterly necessary a perfect remasterizing . Produced in low budget by by Sam Katzsman , due to a combination of astute marketing and the fact that he ground out films so quickly and cheaply that he could cash in on a fad before it faded away, Katzman's movies seldom if ever lost money , taking a lot of stock footage here and there .William Castle used battle footage from Last of the Comanches (1953) , Buffalo Bill by William A Wellman and other films from Columbia Pictures at charge of production .This low-budgeted motion picture was profesional but regularly directed by William Castle . He was an expert craftsman with some of the all-time great schlock names serving as the producer Sam Katzman and fondness for gimmicks as proved in his successful terror films such as House of haunted hill , The Tingler , Mr Sardonicus , Strait-jacked , Homicidal , Macabre and 13 Ghosts . Castle emulated Alfred Hitchcock , this included the practice of appearing in the trailers, and even making cameo appearances in his films . Furthermore , he made several Western such as 1955 Duel on the Mississippi , 1955 The Gun That Won the West ,1955 El Americano , 1954 Masterson of Kansas , 1954 The Law vs. Billy the Kid , 1954 Jesse James vs. the Daltons , 1954 Battle of Rogue River , 1953 Fort Ti , 1951 cave of outlaws. Rating : 5/10 . So-so and average Western oater .
