Query: The world of the Comanchees and the white man in the 1800s

This marvelous story focuses on Liverpool Morgan, a simple but very literate former Confederate army man who, after the Civil War, works for the Indian Agency and the army in Oklahoma Territory. His friendship with the Commanche tribe and its intelligent, perceptive chief, who are struggling to adapt to the world of the white man and the disappearance of their world in just a few decades, is wonderfully told. It's really a classic and must be based on true stories of this frontier.
