Hunkpapa Lakota Chief Sitting Bull [PDF ebook] 

Sitting Bull was the greatest chief of the Sioux. As both war chief and medicine man, Sitting Bull led the Sioux in their victory at the Battle of Little Bighorn, but he also led them through their years of hardship and turmoil. Rather than surrender, Sitting Bull united many Native American tribes in the struggle to protect the great Plains and the sacred Black Hills of South Dakota.
