The story combines two real-life elements, one that happened in 1861, the other (the battle) in 1862, making this something of a prequel to Broken Arrow (1950). The events in that film took place in 1871 and 1872. Jeff Chandler and Jay Silverheels reprised their roles from the previous film, as Cochise and Geronimo respectively.
Jay Silverheels, a Native American Mohawk actor from Canada's Six Nation's Reserve, played Geronimo.
In politically incorrect casting, Jewish actors Jeff Chandler and Susan Cabot played Native American Indians in this film.
