Geronimo (1829–1909), whose Dineh name was Goyathlay, or "one who yawns," became one of the greatest Native American leaders. He led a group of over 400 Chiricahua soldiers in a revolt against the U.S. Army that lasted ten years. Geronimo and his men surrendered in 1886. Geronimo was told he would be allowed to return to his native lands after a brief term of imprisonment in Florida and Alabama. This promise, however, turned out to be one of the many false promises the United States government made to native peoples. Geronimo never regained the freedom he so highly prized. In 1894, he was sent to Fort Sill, Oklahoma, to live out the rest of his life as a captive. It was at Fort Sill, in 1906, that Geronimo dictated his autobiography to Stephen M. Barrett.
