ABSTRACT
Pachacuti Inca Yupanqui found himself so powerful with the companies he had got together by liberal presents to all, that he proposed to subjugate by their means all the territories he could reach. For this he mustered all the troops that were in Cuzco, and provided them with arms, and all that was necessary for war. Affairs being in this state Pachacuti heard that his brother U rco was in a valley called Yucay, four leagues from Cuzco, and that he had assembled some people. Fearing that the movement was intended against him the Inca marched there with his army. His brother Inca Rocca went with him, who had the reputation of being a great necromancer. Arriving at a place called Paca in the said valley, the Inca went out against his brother Urco, and there was a battle between them. Inca Rocca hurled a stone which hit U rco on the throat. The blow was so
105 great that U rco fell into the river flowing down the ravine where they were fighting. U rco exerted himself and fled, swimming down the river, with his axe in his hand. In this way he reached a rock called Chupellusca, a league below Tampu, where his brothers overtook him and killed him.
