The life of Buffalo Bill Cody was as epic and exciting as the story of the West itself. Cowboy, Pony Express rider, Indian fighter, Union soldier, scout for General George Custer, slayer of Tall Bull and Yellow Hand—he saved Wild Bill Hickok's life, and beat the paths that made way for the railroad and the nation in America's rugged frontier.
