It was part of the Arauco War.

After toqui Ainavillo's defeat in the Battle of Andalien he gathered tens of thousands of warriors from the Arauco and Tucapel regions to reinforce his depleted 15,000 man army for an attack on Valdivia's new settlement at Penco. Meanwhile Valdivia's force took eight days to construct a fort with a circuit of 1500 paces around his new settlement with a ditch 12 feet deep and wide. The excavated earth was used to fill in behind a wall of tree trunks driven into the earth above the ditch. It had three gates with well built bastions provided with artillery. Following the construction of the fort, Valdivia established the city of "Concepción del Nuevo Extremo" there on March 3, 1550. He also sent out patrols of his cavalry to call on the local Mapuche to submit to Spanish rule and provide food and service to the Spanish.

On March 12th, Ainavillo's army of sixty thousand warriors advanced against the fort at Penco in three separte bodies with 5,000 skirmishers covering their advance and deployment. Once they had arrived they surrounded the fort on all sides but were not equipped to storm the deep ditch and the wall above it. They could only fire arrows and stones at the walls and shout threats leaving the Spanish safe inside. Inside the fort there was some discontent among the conquistadors at being so hemmed in and letting the Mapuche gain courage thinking the Spaniards were afraid of them by not fighting in the field where their cavalry had always been able to defeat these enemies.

Meanwhile Ainavillo's command that had been previously defeated at Andalien, was recognized by the Spaniards, and they also saw that the Mapuche divisions were separated from each other in a way that prevented them from aiding one another easily. Jerónimo de Alderete without Valdivia's permission picked out Ainavillo's division for a vigorous charge by his cavalry but the Mapuche had learned to close their ranks, presenting their copper tipped pikes and this repelled the Spanish charge with some injury to their horses leaving the Mapuche untouched.

Valdivia realized that Alderete had forced his hand and sent out Pedro de Villagra with the rest of the cavalry and directed the softening up of Ainavillo's command by volleys of their firearms and artillery. Jeronimo de Alderete and Pedro de Villagra then led a new charge that broke Ainavillo's disordered division at the first onslaught and they fled with the Spanish in pursuit, followed by the rout of the other two commands of Mapuche upon seeing the spectacle. Where the fleeing Mapuche entered terrain the cavalry could not follow the Spanish foot and Michimalonco's warriors followed killing many [ Lobera, Crónica, Capítulo XXXIII ] . The battlefield was littered with discarded weapons, 300 dead Indians killed in the clash with Ainavillo alone, according to Vivar, 4,000 was the total Mapuche loss after the pursuit, according to Lobera, and 200 were captured including many leaders of the army. Valdivia had the nose and one hand of each of the prisoners cut off and sent them back with a message that the Mapuche should now submit to Spanish rule. Soon afterward the Mapuche leaders came to submit to the Spanish.
