While the surviving Mapuche forces were still retreating, an advance party commanded by Pedro de Avendaño arrived at Pilmaiquen, and in the Battle of Antihuala (on 5 February 1558) they captured Caupolican, who was in process of preparing a counteroffensive. According to De Vivar, while he was being guided, tied up, by a squad of Spanish soldiers towards the fort of Tucapel, an irate Mapuche woman appeared in front of them, whose name was Fresia, with a baby in her arms; the baby was a child of the defeated toqui. The woman reprimanded him for having allowed himself to be captured alive; she threw the baby down at his feet and walked away, useless the cries given asking her to return for the child. The march continued silently in its direction. He was taken before the veteran Alonso de Reinoso, who condemned him to die by impalement. Cristobal de Arevalo, the field marshal, was asked to be the executioner. Caupolican was taken and tied to a raised platform with a sharp wooden spike.
