A lot of the B Westerns were "fluff", but usually the director or writer would want to add some "sidebar" on for their personal motif.
It is the "sidebar" that is usually the message the director and writer want to display. Sometimes, it is "advertising" for products, such as tobacco companies, soda companies, or what have you.
Here, either Director Selander, or writers Simmons and Boone, looked to want to add their own flavor to a fairly routine cavalry Western.
Like most Westerns of the day, the Indians are depicted as semi good guys with evil white men upsetting the apple cart.
The overkill of the evil white men has always been very politically correct, and especially was in the decades that followed this movie.
However, the real sidebar here is what happens with the evil corrupt cavalry officer who causes at least two massacres, quite knowingly, quite viciously.
Also, a few red herrings come into play here. The fates of a few of the characters you won't guess, as they go against the usual Hollywood propaganda formula. Thus, this particular Western has some surprises by the end.
