At this time, the Spanish were still unaware of the death of the previous
Sapa Inca (Titu Cusi) and had routinely sent two ambassadors to continue ongoing negotiations being held with Titu Cusi. They were both killed on the border by an Inca captain. Using the justification that the Incas had "broken the inviolate law observed by all nations of the world regarding ambassadors", the new viceroy,
Francisco de Toledo, Count of Oropesa, decided to attack and conquer Vilcabamba. He declared war on 14 April 1572. The first engagement of the war commenced in the Vilcabamba valley on 1 June. The Inca people attacked first with much spirit despite being only lightly armed. Again and again, they attempted to lift the siege held by the Spanish and their native allies but each time they were forced to retreat. On 24 June the Spanish entered Vilcabamba to find it deserted and the
Sapa Inca gone. The city had been entirely destroyed and the last remnants of the
Inca Empire, the
Neo-Inca State now officially ceased to exist. Túpac Amaru had left the previous day with a party of about 100 and headed west into the lowland forests. The group, which included his generals and family members, had then split up into smaller parties in an attempt to avoid capture. Three groups of Spanish soldiers pursued them. One group captured Titu Cusi's son and wife. A second returned with military prisoners along with gold, silver and other precious jewels. The third group returned with Túpac Amaru's two brothers, other relatives and several of his generals. The
Sapa Inca and his commander remained at large. Following this, a group of forty hand-picked soldiers under
Martín García Óñez de Loyola set out to pursue them. They followed the Masahuay river for 170 miles, where they found an Inca warehouse with quantities of gold and the Inca's tableware. The Spanish captured a group of Chunco and compelled them to tell them what they had seen and if they had seen the
Sapa Inca. They reported that he had gone down river, by boat, to a place called Momorí. The Spaniards then constructed five rafts and pursued them. At Momorí, they discovered that Tupac Amaru had escaped by land. They followed with the help of the Manarí, who advised which path the Inca had followed and reported that Túpac was slowed by his wife, who was about to give birth. After a fifty-mile march, they saw a campfire around nine o'clock at night. They found the
Sapa Inca Túpac Amaru and his wife warming themselves. They assured them that no harm would come to them and secured their surrender. Túpac Amaru was arrested. The captives were brought back to the ruins of Vilcabamba and together they were all marched into Cuzco on 21 September. The invaders also brought the mummified remains of
Manco Cápac and
Titu Cusi and a gold statue of Punchao, a representation of the Inca's lineage containing the mortal remains of the hearts of the deceased Inca kings. These sacred items were then destroyed. == Execution ==
