Passage: The story begins in 1885 with the arrival of an important new guest star in Buffalo Bill Cody's grand illusion, Chief Sitting Bull of Little Big Horn fame. Much to Cody's annoyance, Sitting Bull proves not to be a murdering savage but a genuine embodiment of what the whites believe about their own history out west. He is quietly heroic and morally pure.

Question: What battle was Chief Sitting Bull most famous for?
Little Big Horn
