River, which he was inclined to think was a tributary of the Rio de la
Plata. He describes fierce battles with the Chunchos, who were reduced
to obedience. After descending the River Tono, Garcilasso says that the
Incas eventually reached the country of the Musus (Moxos) and opened
friendly relations with them. Many Incas settled in the country of the
Musus. Garcilasso then gives some account of Spanish expeditions into
the montana, led by Diego Aleman, Gomez de Tordoya, and Juan Alvarez
Maldonado.

The account in the text agrees, in the main, with that of Garcilasso de
la Vega. Sarmiento gives the names of four Indian tribes who were
encountered, besides the Chunchos.]

During the campaign an Indian of the Collas, named Coaquiri, fled from
his company, reached the Collao, and spread the report that Tupac Inca
was dead. He said that there was no longer an Inca, that they should all
rise and that he would be their leader. Presently he took the name of
Pachacuti, the Collas rose, and chose him as their captain. This news
reached Tupac Inca in Anti-suyu where he was in the career of conquest.
He resolved to march against the Collas and punish them. He left the
forests, leaving Uturuncu Achachi to complete the conquest, with orders
to return into Peru when that service was completed, but not to enter
Cuzco triumphing until the Inca should come.

TUPAC INCA YUPANQUI GOES TO SUBDUE AND PACIFY THE COLLAS.

As the Collas were one of those nations which most desired their
freedom, they entered upon attempts to obtain it whenever a chance
offered, as has already been explained. Tupac Inca Yupanqui resolved to
crush them once for all. Having returned from the Antis, he increased
his army and nominated as captains Larico, the son of his cousin Ccapac
Yupanqui, his brother Chachi, Cunti Yupanqui, and Quihual Tupac. With
this army he advanced to the Collao. The Collas had constructed four
strong places at Llallaua, Asillo, Arapa, and Pucara. The Inca captured
the chiefs and the leader of all, who was Chuca-chucay Pachacuti
Coaquiri, he who, as we have said, fled from Anti-suyu. Afterwards these
were the drummers[107] of Inca Tupac. Finally, owing to the great
diligence of Inca Tupac, although the war occupied some years, the Incas
conquered and subdued all [_perpetrating great cruelties on them_].

Following up his victories, in pursuit of the vanquished, he got so far
from Cuzco that he found himself in C
