Delve deeper into the struggle for lands in the Plains between the 1850s and the 1870s. You'll meet the fighters you've heard of, such as Sitting Bull, as well as those you may not have heard about, such as the Hunkpapa Gall, the Oglala Crazy Horse, and the Northern Cheyenne Wooden Leg, who led successful battles and defeated General Custer. You'll also see the negative repercussions of the 1869 completion of the Transcontinental Railroad.
