PACHACUTI INCA YUPANQUI CONQUERS THE PROVINCE OF COLLA-SUYU.
To the south of Cuzco there was a province called Colla-suyu or Collao, consisting of plain country, which was very populous. At the time that Pachacuti Inca Yupanqui was at Cuzco after having conquered the provinces already mentioned, the Sinchi of Collao was named Chuchi Ccapac or Colla Ccapac, which is all one. This Chuchi Ccapac increased so much in power and wealth among those nations of Colla-suyu, that he was respected by all the Collas, who called him Inca Ccapac.
Pachacuti Inca Yupanqui determined to conquer him from a motive of jealousy, together with all the provinces of the Collao. With this object he assembled his army and marched on the route to the Collao in order to attack Chuchi Ccapac who waited for him at Hatun-Colla, a town of the Collao where he resided, 40 leagues from Cuzco, without having taken further notice of the coming nor of the forces of Inca Yupanqui. When he came near to Hatun Colla, the Inca sent a message to Chuchi Colla, requesting him to serve and obey him or else to prepare for battle, when they would try their fortunes. This message caused much heaviness to Chuchi Colla, but he replied proudly that he waited for the Inca to come and do homage to him like the other nations that had been conquered by him, and that if the Inca did not choose to do so, he would prepare his head, with which he intended to drink in his triumph after the victory which he would win if they should come to a battle.
After this reply Inca Yupanqui ordered his army to approach that of Chuchi Ccapac the next day, which was drawn up ready to fight. Soon after they came in sight, the two forces attacked each other, and the battle continued for a long time without either side gaining any advantage. Inca Yupanqui, who was very dexterous in fighting, was assisting in every part, giving orders, combating, and animating his troops. Seeing that the Collas resisted so resolutely, and stood so firmly in the battle, he turned his face to his men saying in a loud voice: "O Incas of Cuzco! conquerors of all the land! Are you not ashamed that people so inferior to you, and unequal in weapons, should be equal to you and resist for so long a time?" With this he returned to the fight, and the troops, touched by this rebuke, pressed upon their enemies in such sort that they were broken and defeated. Inca Yupanqui, being an experienced warrior, knew that the completion of the victory consisted in the capture of Chuchi Ccapac. Although he was fighting, he looked out for his enemy in all directions and, seeing him in the midst of his people, the Inca attacked them at the head of his guards, took him prisoner, and delivered him to a soldier with orders to take him to the camp and keep him safe. The Inca and his army then completed the victory and engaged in the pursuit, until all the Sinchis and captains that could be found were captured. Pachacuti went to Hatun-colla, the residence and seat of government of Chuchi Ccapac, where he remained until all the provinces which obeyed Chuchi Ccapac, were reduced to obedience, and brought many rich presents of gold, silver, cloths, and other precious things.
