The Battle of Chimborazo was among the first confrontations in the War of the two brothers, a struggle between Huáscar and Atahualpa for power over the Inca Empire.
However, Atahualpa escaped and united himself with Huayna Capac's generals Quizquiz and Chalicuchima, both skillful, and together they attacked Huáscar near Chimborazo.
The foundations of Huáscar's power were shaken by the defeat, and in the next year, all Cusco dominance came to an end at Quipaipan.
Pedro Sarmiento de Gamboa claims he and second-in command Hango were flayed and their skins used as drums.
Ullco Colla, lord of the defected Tumipampa tribe, died in battle and his city captured shortly after, but reportedly spared by Atahualpa.
