The flag lowered at the end of the movie has 35 stars rather than 37, which was the approved flag for 1876. The US has never retired a flag design, therefore a flag with 35 stars would not be unusual for a frontier post in 1876.
The surname 'Kellogg' is used for two characters in the film - the colonel and his daughter Martha. It is also the surname of Mark Kellogg, a newspaper reporter who rode with Custer's troops. He was killed at the Battle of the Little Big Horn.
