bold and general attack, and dismayed by the loss of their cannon, the Spanish horse and foot fell into confusion and disorder, and were so furiously pressed upon by the valiant Lautaro and his troops, that they dispersed and fled with the utmost precipitation.  Three thousand of the Spaniards and their Promaucian allies were slain in this decisive battle, Villagran himself, having fallen in the retreat, was on the point of being taken prisoner, when he was rescued by the almost incredible efforts of three of his soldiers, and remounted on his horse.  The remaining Spaniards urged on their almost exhausted horses to regain the narrow defile where the engagement had commenced, and were closely pursued by the Araucanians; but on arriving at the pass, they found it blocked up with trees, which had been felled across by orders of Lautaro.  The engagement was renewed at this place with the utmost fury, and not a man of the broken army would have escaped, had not Villagran opened the pass at the utmost hazard of his life.  Though the Araucanians had lost above seven hundred men in the course of this eventful battle, they continued the pursuit a long way; but at length, unable to keep up with the horses, and exhausted with excessive fatigue, they gave up the pursuit, and Lautaro encamped for the night to refresh his men, determined upon passing the Biobio next day to follow up the consequences of his glorious and decisive victory.

On the arrival of the few Spaniards at Conception who had been able to escape from the slaughter at Mariguenu, the city of Conception was filled with indescribable grief and dismay, not a family but had to deplore the loss of some near relation; and the alarm was greatly increased by learning that Lautaro was fast approaching with his victorious army.  As Villagran considered it to be impossible to defend the city under the present dismay of his small remaining force, he hastily embarked all the old men, women, and children on board two ships that happened to be then in the harbour, one of which he ordered to proceed to Imperial, and the other to Valparaiso, while he proceeded by land for St Jago with all the rest of the inhabitants who were able to carry arms.  Lautaro entered the city next day without opposition, which he found entirely deserted of its inhabitants, but filled with much valuable booty, as by its mines and commerce it had already attained considerable opulence, and the inhabitants were in such haste to escape with their lives, that they only took what provisions they could procure along with them, and abandoned their riches.  After removing every thing that was valuable, Lautaro burnt all the houses, and razed the citadel and other fortifications; after which he returned with his army to Arauco, to celebrate his triumph after the manner usual in his country.
