This is a strange western that I think owes some inspiration from John Ford's classic Cheyenne Autumn. Like the Ford movie it's concerning starving Indians on the reservation, in this case Arapahoe who resolve not to starve any longer.
Especially when post commander John Mills has plenty of army supplies in his fort and won't feed the Arapahoe or give them guns to hunt. His fort is a last chance outpost where apparently the army sends all its misfits from the commander on down. Holding some kind of discipline together is Sergeant Ernest Borgnine.
Into the mix rides gunfighter Rod Taylor in the title role together with Luciana Paluzzi and her niece Victoria Vetri. Paluzzi and Taylor had a little something something going back in the day.
In any event the Arapahoes have them boxed in with a massacre impending. Our sympathies are completely with the Indians on this one. This post contains some of the worst specimens of human being ever gathered together in one spot. Mills is a frightening spectacle with Borgnine enforcing his edicts on an unruly post. Of course there's a reason he's a drunken shell of a man which we learn near the end of the film.
Chuka misses being a classic because of the pedestrian direction it got from Gordon Douglas. Someone like Delmar Daves or John Huston could have made it a classic. The cast is a good one.
John Ford would never have directed it though, no way he would have portrayed his beloved United States Cavalry like this.
