Tupac Amaru, another son of Manco II, now became Inca. His only distinction was that he was to be the last. The Spaniards
now decided to breach the great stronghold of Vilcabamba in the three known entries. After a sharp struggle, Tupac Amaru
and all of his principal captains were captured and in 1572, chained neck to neck, were marched to Cusco. The Inca was
hastily tried and led to the great square of Cusco. There, before a mass of people packed so tightly that ``if an orange had been
thrown it would not have reached the ground,'' Tupac Amaru, the last of the Incas, was beheaded by a Cañari Indian. The
Neo-Inca state had endured as a serious threat to the Spanish occupation from 1536 until 1572.
