This aired in 1999 on Montana public broadcasting. It’s worth setting aside some time to watch (or watch again).
The program tells the story of the 25th Infantry’s bicycle trip from Missoula, Montana, to St. Louis, Missouri in 1897. The African American infantry took the trip to test a theory that the bicycle would replace the horse in transporting men for the army. The program also examines the life of the African American soldier at the turn of the century, in particular First Sergeant Mingo Sanders.
