According to the "Chronicles of the Indias", which are kept in
Seville, Spain, in February 1511, Agueybana's brother Güeybaná, better known as
Agüeybaná II (The Brave), Urayoan, the Cacique of
Añasco and some of their men drowned the Spanish soldier
Diego Salcedo. They watched over Salcedo's body to see if he came back to life. When he did not, the Taínos realized that the Spaniards were not
gods after all. The Cacique Jumacao was the first Cacique to learn how to read and write in Spanish. He proved this by writing a letter to King
Charles I of Spain, complaining that the appointed governor of the island was not honoring the peace treaty and that he and the other Caciques had virtually become prisoners of the governor. He also stated that he was responsible for his own acts. The King was moved by the letter and ordered the governor to honor the terms of the treaty. The government, however, paid no attention to the King's request and continued to abuse the Taínos. Jumacao, together with the help of the Cacique Daguao (Cacique of
Naguabo), attacked Spanish settlements and burned down the City of Santiago (founded in 1513), which was located close to the Daguao (now Santiago) River, killing all of its inhabitants. According to the testimony of Ignacio Martinez, the sole survivor of the "Santiago incident", the Caciques and their tribes hid in the Sierras (mountains) of
Luquillo. Jumacao was never heard from again. ==Legacy==
