Black Hawk, originally Makataimeshekiakiak, a noted leader of Sauk, fought with the British against the Americans in the war of 1812 and opposed policies of Keokuk of accommodation with the government of the United States; its troops in a brief known conflict of 1832 defeated him.
Zachary Taylor served as an officer of Army in the war of 1832 against Black Hawk.
Keokuk, leader of Sauk, aided the United States in the war of 1832 against Black Hawk and negotiated peace between his people and the Lakota in 1837.
The first half of the book, which is Blackhawk's story of his life from his point of view was quite good. The second half, which details many of the multiple battles between Blackhawk's tribe and fellow tribes against the American military is a bit difficult to follow, and not very clear if this is also from Blackhawk's point of view, or the writer's.
