All star cast, Pure fiction, Some real details about Little Bighorn people, poor ratings.
Yes, it was pure fiction and pure entertainment. However, the show was not cancelled due to poor ratings. It was cancelled due to protests from American Indian groups who were angered that Custer was made into a hero in this series. This was the beginning of the movement by the media and Hollywood to denigrate traditional American heroes like Buffalo Bill, Davy Crockett, Kit Carson, etc.
"The more I see of movement here (Little Big Horn Battlefield), the more I have admiration for Custer, and I am satisfied his like will not be found very soon again.”
~ Gen. Nelson Miles, Commanding General of the Army ------
"With our cherished ones deliverance within our grasp we waited breathless two hours, for the order that never came."
