February 1554 CE
It is only in February of 1554 that Lautaro succeeds in assembling an army of eight thousand men, just in time to confront a punitive expedition under the command of Francisco de Villagra.
Lautaro chooses the hill of Marihueño to fight the Spanish, and subsequently organizes his forces in four divisions: two to contain and wear down the enemy, another held in reserve to launch a fresh attack as the Spanish were about to crumble, and the last to cut off their retreat.
Additionally, a small group is sent to destroy the reed bridge the Spanish had erected across the Bío-Bío River, which would disrupt even more the attempted retreat of Villagra.
The Spanish attack breaks the first Mapuche lines, but the quick action of the third group maintains the defenders’ position.
Soon, the wings of this division begin to attack the Spanish flanks, and the fourth division attacks from behind.
After hours of battle, only a small group of Spanish are able to retreat.
Despite this new victory, Lautaro is again unable to pursue the opportunity due to the celebrations and beliefs of his people.
By the time he arrives at Concepción, it is already abandoned.
After burning it, he cannot continue the offensive with his remaining forces, and the campaign ends as the warriors demobilize.
