Vilumilla was chosen, despite being a man of low rank, because he was one who had acquired a high reputation for his judgment, courage and his larger strategic view of the war to come.
Having destroyed these two places he marched against the fort of Purén, but the garrison commander Urrea, opposed him so effectively that he was forced to besiege it.
However, in a short time the garrison was reduced to desperation from thirst, for the Mapuche had cut the aqueduct which supplied them with water.
Seeing this position Cano, though repeatedly provoked by the Mapuche, thought it advisable to abandon Purén, and retire with the garrison.
The war afterwards became reduced to minor skirmishes, which was finally ended by the Parliament of Negrete of 1726, in which both sides signed the Peace of Negrete, where the Treaty of Quillan was reconfirmed, a system of regulated fairs were established and the hated title of Captain of Friends was abolished.
