Are there any historically accurate westerns?

What about the "foul" guy, Timmons, who escorts Dunbar to the abandoned fort? I've met people just like him. He's not portrayed as evil, but merely uncouth in dress and manners. When Timmons is savagely murdered by a band of Pawnee he begs over and over that the Indians not hurt his mules; his dying words are words of love (for his animals!). Also, when he says goodbye to Dunbar at the fort he says, "Good luck, Lieutenant" and you know he means it; the words show love and respect. Obviously this was a physically disgusting guy with a heart of gold. Again I know people just like him; it rings of authenticity.

The story takes place during the Indian Wars where there's very little love & compassion of whites towards Natives and vice versa. The U.S. Army is there to do a job and, as usual, go by the book. Is this a negative portrayal or simply the way it was? The answer is obvious. Hence, most of the officers are not shown in a negative light but merely as military leaders carrying out their duty. While some of the main enlisted soldiers come off as clueless sheetheads, the characters ring of true life. I met people just like 'em in the military.

Besides, I repeat, not all Natives are depicted as virtuous. The Pawnee are obviously ruthless villains and quite a few Indians are shown helping the U.S. Army and are, therefore, traitors to their people.

Is the small tribe of Lakota Sioux really super-virtuous? Is their lifestyle really a paradise? No, they're merely portrayed as real people living, pursuing happiness, uncertain about the amassing whites, fighting and persevering through hardships (like the winter camp).

Is the massive annihilation of Bison (leaving their skinless carcasses to rot in the sun) a negative depiction of whites or just the way it was? Such people would likely shoot a wolf for the "fun" of it. Again, it smacks of reality.

As to the accuracy of the story itself, the fact is that many whites have "gone injun" and many Natives have assimilated with whites. The story explores the possibility of what would happen IF a white man dropped his prejudices and tried to get along with some Sioux neighbors; and what if this small band of Natives was open and curious enough to accept him? Is it unlikely that this band would have an available white woman amongst them that Dunbar could fall in love with? Is there a bit of romanticization? Yes, but it IS a Hollywood movie, after all. Regardless, it's presented in a believable, compelling and captivating way.

A bunch of them I haven't seen, and a bunch I have seen I can't remember because they were forgettable movies.
