Immediately after this signal victory, Antiguenu marched against the fortress of Canete, rightly judging that it would not be in a condition to resist him in the present circumstances. Villagran was likewise convinced of the impossibility of defending that place, and anticipating the design of the Araucanian general, ordered all the inhabitants to withdraw, part of whom retired to Imperial and the rest to Conception. Antiguenu, therefore, on his arrival at that place, so fatal to his nation, had only the trouble of destroying the fortifications and setting fire to the houses, all of which he completely destroyed.
Overcome with grief and anxiety, Villagran died soon after the disastrous battle of Mariguenu, universally regretted by the Spanish inhabitants of Chili, who lost in him a wise humane and valiant governor, to whose prudent conduct on several trying occasions they had been much beholden for the preservation of their conquests. Before his death, in virtue of special powers vested in him by his commission from the court of Spain, he appointed his eldest son Pedro to succeed him in the government, whose endowments of mind were in no respect inferior to those of his father. By the death of the governor, Antiguenu conceived that he had a favourable opportunity for undertaking some important enterprise. He divided his army, which now consisted of 4000 men, into two bodies, one of which he ordered to lay siege to Conception under the command of his vice-toqui Antunecul, to attract the attention of the Spaniards in that quarter, while he marched with the other division to invest the fort of Arauco, which was defended by a strong garrison under the command of Lorenzo Bernal.
