Immediately on receiving intelligence of the victory which Gonzalo had gained at Guarina, the president sent the captains Lope Martin and Mercadillo, with a detachment of fifty men, to occupy the passes of Guamanga, about thirty leagues from Jauja on the way to Cuzco, to learn the motions of the enemy, and to collect all who might have been able to escape from Cuzco. While at Guamanga, Lope Martin got notice that Pedro de Bustincia was in the district of Andahuaylas collecting provisions for the army of Gonzalo, as formerly mentioned. Accompanied by fifteen mounted musqueteers, Martin went into that district, where he unexpectedly attacked Bustincia during the night, and made him and all his people prisoners.
