At the time when Inca Viracocha left Cuzco, Asto-huaraca and Tomay-huaraca set out for Ichu-pampa, first making sacrifices and blowing out the lungs of an animal, which they call calpa. This they did not well understand, from what happened afterwards. Marching on towards Cuzco, they arrived at a place called Conchacalla, where they took a prisoner. From him they learnt what was happening at Cuzco, and he offered to guide them there secretly. Thus he conducted them half way. But then his conscience cried out to him touching the evil he was doing. So he fled to Cuzco, and gave the news that the Chancas were resolutely advancing. The news of this Indian, who was a Quillis-cachi of Cuzco, made Viracocha hasten his flight to Chita, whither the Chancas sent their messengers summoning him to surrender, and threatening war if he refused. Others say that these were not messengers but scouts and that Inca Viracocha, knowing this, told them that he knew they were spies of the Chancas, that he did not want to kill them, but that they might return and tell their people that if they wanted anything he was there. So they departed and at the mouth of a channel of water some of them fell and were killed. At this the Chancas were much annoyed. They said that the messengers had been ordered to go to Inca Viracocha, and that they were killed by his captain Quequo Mayta.

While this was proceeding with the messengers of the Chancas, the Chanca army was coming nearer to Cuzco. Inca Yupanqui made great praying to Viracocha and to the Sun to protect the city. One day he was at Susurpuquio in great affliction, thinking over the best plan for opposing his enemies, when there appeared a person in the air like the Sun, consoling him and animating him for the battle. This being held up to him a mirror in which the provinces he would subdue were shown, and told him that he would be greater than any of his ancestors: he was to have no doubt, but to return to the city, because he would conquer the Chancas who were marching on Cuzco. With these words the vision animated Inca Yupanqui. He took the mirror, which he carried with him ever afterwards, in peace or war, and returned to the city, where he began to encourage those he had left there, and some who came from afar[79]. The latter came to look on, not daring to declare for either party, fearing the rage of the conqueror if they should join the conquered side. Inca Yupanqui, though only a lad of 20 or 22 years, provided for everything as one who was about to fight for his life.

[Note 79: Susurpuquio seems to have been a fountain or spring on the road to Xaquixahuana. Molina relates the story of the vision somewhat differently, p. 12. Mrs. Zelia Nuttall thinks that the description of the vision bears such a very strong resemblance to a bas relief found in Guatemala that they must have a common origin.]

While the Inca Yupanqui was thus engaged the Chancas had been marching, and reached a place very near Cuzco called Cusi-pampa, there being nothing between it and Cuzco but a low hill. Here the Quillis-cachi was encountered again. He said that he had been to spy, and that he rejoiced to meet them. This deceiver went from one side to the other, always keeping friends with both, to secure the favour of the side which eventually conquered. The Chancas resumed the march, expecting that there would be no defence. But the Quillis-cachi, mourning over the destruction of his country, disappeared from among the Chancas and went to Cuzco to give the alarm. "To arms! to arms!" he shouted, "Inca Yupanqui. The Chancas are upon you."

At these words the Inca, who was not off his guard, mustered and got his troops in order, but he found very few willing to go forth with him to oppose the enemy, almost all took to the hills to watch the event. With those who were willing to follow, though few in number, chiefly the men of the seven Sinchis, brothers and captains, named above, he formed a small force and came forth to receive the enemy who advanced in fury and without order. The opposing forces advanced towards each other, the Chancas attacking the city in four directions. The Inca Yupanqui sent all the succour he could to the assailed points, while he and his friends advanced towards the statue and standard of Uscovilca, with Asto-huaraca and Tomay-huaraca defending them. Here there was a bloody and desperate battle, one side striving to enter the city, and the other opposing its advance. Those who entered by a suburb called Chocos-chacona were valiantly repulsed by the inhabitants. They say that a woman named ChaÑan-ccuri-coca here fought like a man, and so valiantly opposed the Chancas that they were obliged to retire. This was the cause that all the Chancas who saw it were dismayed. The Inca Yupanqui meanwhile was so quick and dexterous with his weapon, that those who carried the statue of Uscovilca became alarmed, and their fear was increased when they saw great numbers of men coming down from the hills. They say that these were sent by Viracocha, the creator, as succour for the Inca. The Chancas began to give way, leaving the statue of Uscovilca, and they say even that of Ancovilca. Attacking on two sides, Inca Rocca, Apu Mayta, and Vicaquirau made great havock among the Chancas. Seeing that their only safety was in flight, they turned their backs, and their quickness in running exceeded their fierceness in advancing. The men of Cuzco continued the pursuit, killing and wounding, for more than two leagues, when they desisted. The Chancas returned to Ichu-pampa, and the orejones to Cuzco, having won a great victory and taken a vast amount of plunder which remained in their hands. The Cuzcos rejoiced at this victory won with so little expectation or hope. They honoured Inca Yupanqui with many epithets, especially calling him PACHACUTI, which means "over-turner of the earth," alluding to the land and farms which they looked upon as lost by the coming of the Chancas. For he had made them free and safe again. From that time he was called Pachacuti Inca Yupanqui.

As soon as the victory was secure, Inca Yupanqui did not wish to enjoy the triumph although many tried to persuade him. He wished to give his father the glory of such a great victory. So he collected the most precious spoils, and took them to his father who was in Chita, with a principal orejon named Quillis-cachi Urco Huaranca. By him he sent to ask his father to enjoy that triumph and tread on those spoils of the enemy, a custom they have as a sign of victory. When Quillis-cachi Urco Huaranca arrived before Viracocha Inca, he placed those spoils of the Chancas at his feet with great reverence, saying, "Inca Viracocha! thy son Pachacuti Inca Yupanqui, to whom the Sun has given such a great victory, vanquishing the powerful Chancas, sends me to salute you, and says that, as a good and humble son he wishes you to triumph over your victory and to tread upon these spoils of your enemies, conquered by your hands." Inca Viracocha did not wish to tread on them, but said that his son Inca Urco should do so, as he was to succeed to the Incaship. Hearing this the messenger rose and gave utterance to furious words, saying that he did not come for cowards to triumph by the deeds of Pachacuti. He added that if Viracocha did not wish to receive this recognition from so valiant a son, it would be better that Pachachuti should enjoy the glory for which he had worked. With this he returned to Cuzco, and told Pachacuti what had happened with his father.
