Having determined to march, to the Collao, the Inca set out from the city of Cuzco with a large force, passing by Muyna, and by the towns of Urcos and Quiquijana. When the Canches, heard of his approach, they determined to assemble and come forth with their arms, to defend the passage through their land. The Inca, on receiving news of their intention, sent messengers to represent that they should not undertake such an enterprise, for that he did not wish to give them any affront, but rather desired to be their friend, and if their chiefs and captains would come to him, he would give them to drink from his own cup. The Canches replied to the messengers that the Inca should not pass by reason of what they said, and that they were there to defend their country which had been invaded. Returning with this answer, the messengers found the Inca Viracocha in Cangalla, full of anger at the small account in which the Canches held his embassy. He made a rapid march, arriving at a town which is called Compata. Near a river which flows close by, he found the Canches drawn up in order of battle, and here the combat between the two forces took place. Many died on both sides, and the Canches were defeated. Those who were able to do so, fled, and were followed by the conquerors, killing and taking prisoners. After a long time the pursuers returned with the spoils, bringing with them many prisoners, both men and women.
