Hernando Pizarro convinced Chalcuchimac, camped with an army of 35,000 in the Jauja Valley, that he was called to Cajamarca by Atahualpa after the Battle of Cajamarca. Chalcuchimac was also arrested by the Spaniards, who feared he might resume hostilities. Once Atahualpa had been executed on July 29, 1533, Pizarro advanced with his army of five hundred Spaniards toward Cuzco, accompanied by Chalcuchimac and then Manco Inca Yupanqui, after the death of Túpac Huallpa.
