was preparing to make war on him, that he
had separated himself from the Hanan-cuzcos, and that he had proclaimed
him, Atahualpa, a traitor, which they call _aucca_. Atahualpa, seeing
the evil designs entertained by his brother against him, and that he
must prepare to defend himself, took counsel with his captains. They
were of one accord that he should not take the field until he had
assembled more men, and collected as large an army as possible, because
negotiations should be commenced when he was ready for battle.

At this time an Orejon named Hancu and another named Atoc came to
Tumipampa to offer sacrifices before the image of Huayna Ccapac, by
order of Huascar. They took the wives of Huayna Ccapac and the insignia
of Inca without communication with Atahualpa. For this Atahualpa seized
them and, being put to the torture, they confessed what orders Huascar
had given them, and that an army was being sent against Atahualpa. They
were ordered to be killed, and drums to be made of their skins. Then
Atahualpa sent scouts along the road to Cuzco, to see what forces were
being sent against him by his brother. The scouts came in sight of the
army of Huascar and brought back the news.

Atahualpa then marched out of Quito to meet his enemies. The two armies
encountered each other at Riopampa where they fought a stubborn and
bloody battle, but Atahualpa was victorious. The dead were so numerous
that he ordered a heap to be made of their bones, as a memorial. Even
now, at this day, the plain may be seen, covered with the bones of those
who were slain in that battle.

At this time Huascar had sent troops to conquer the nations of
Pumacocha, to the east of the Pacamoros, led by Tampu Usca Mayta and by
Titu Atauchi, the brother of Huascar. When the news came of this defeat
at Riopampa, Huascar got together another larger army, and named as
captains Atoc, Huaychac, Hanco, and Huanca Auqui. This Huanca Auqui had
been unfortunate and lost many men in his campaign with the Pacamoros.
His brother, the Inca Huascar, to insult him, sent him gifts suited to a
woman, ridiculing him. This made Huanca Auqui determine to do something
worthy of a man. He marched to Tumipampa, where the army of Atahualpa
was encamped to rest after the battle. Finding it without watchfulness,
he attacked and surprised the enemy, committing much slaughter.

Atahualpa received the news at Quito, and was much grieved that his
brother Huanca Auqui should have ma
