William R. Sanford 
Seminole Chief Osceola [PDF ebook] 

Osceola led his people, the Seminoles, in one of the longest struggles of the Indian Wars. In a game of hide and seek in the Florida wetlands, the Seminoles struck deadly blows to the U.S. Army. Osceoloa was never defeated, but was finally double-crossed and captured. The author tells the real story of this fearless leader. The Seminoles had lived peacefully with Spanish settlers and runaway slaves until Florida became part of the United States. When the U.S. government decided the Seminoles should be moved to distant reservations, Osceola helped lead his people into war.
