 The battle allegedly lasted for an entire day and ended inconclusive, as Chalcuchima and Quizquiz pulled back upon night towards a hill nearby.Huáscar ordered his warriors to burn the grass, causing massive losses among the Atahualpan forces.Instead of pressing this attack, however, Huáscar chose to retreat safely to the south across the river, ordering his brother Topa Atao to fortify a pass carrying the main route to the nearby Inca capital of Cuzco.
