Bolívar: American Liberator by Marie Arana:
In the end, the royalist armies crushed the rebellion, costing the Indians some 100,000 lives. Túpac Amaru II was captured and brought to the main square of Cuzco, where the Spanish visitador asked him for the names of his accomplices. “I only know of two,” the prisoner replied, “and they are you and I: You as the oppressor of my country, and I because I wish to rescue it from your tyrannies.” Infuriated by the impudence, the Spaniard ordered his men to cut out the Indian’s tongue and draw and quarter him on the spot. But the four horses to which they tied his wrists and ankles would not comply. The soldiers slit Túpac Amaru’s throat instead; cut off his head, hands, and feet; and displayed these on stakes at various crossroads in the city. The torture and execution were repeated throughout the day until all members of his family were killed. Seeing his mother’s tongue ripped from her head, Túpac Amaru’s youngest child issued a piercing shriek. Legend has it that the sound of that cry was so heartrending, so unforgettable, that it signaled the end of Spanish dominion in America.
