I am an Englishman interested in the history of the American West, and over the last 50 years have read numerous factual accounts of the period. I have just seen the first episode of this series, and while visually interesting, it does seem to play fast and loose with historical facts. There is no mention of native-American Sioux chief Red Cloud, who was the only tribal chief to defeat the American army, resulting in a peace treaty and the creation of the Great Sioux Reservation. However I can see that this series has been made for the benefit of the masses, and not for any true historian of the period.
