At the very start of John Ford's "She Wore A Yellow Ribbon" his color entry in his Cavalry trilogy, the narrator tells us of an immanent Indian uprising in 1876, right after Custer's Last Stand at Little Bighorn, Montana. He then intones, "Pony Express riders know that one more defeat like Custer's.." However, the Pony Express lasted only from 1860 to 1861.
