He lead about twenty thousand warriors in the surprise night attack on Valdivia's camp in the Battle of Andalien. After his defeat in that battle he gathered more warriors from the allied regions of Arauco and Tucapel, south of the Bio-Bio River, for an attack on Valdivia's newly constucted fort of Concepcion at what is now Penco. Leading an army of sixty thousand warriors in three divisions against the fort in the Battle of Penco [Vivar, Crónica..., Cap. XCVII] . Ainavillo's command that had been previously defeated at Andalien, was recognized by Valdivia and picked out for a vigorous charge by all their cavalry following a softening up by volleys of their firearms. It was broken at the first onslaught and fled with the Spanish in pursuit, followed by the divisions of the other Mapuche upon seeing the spectacle.
