Huáscar opened fire at about 3,000 metres at 09:25, but Almirante Cochrane withheld its reply while closing to roughly 2,200 metres. The Chilean ironclad chose a shorter range before committing its own guns. Over roughly ninety minutes, armour-piercing shells penetrated the monitor and exploded after entering the hull. Boarding parties were mustered by 10:55, and about twenty sailors boarded at 11:08 without resistance. Range control, penetrating fire, and boarding converted Chile's encirclement into the capture of the disabled ship.
