When the terror which this young hero had inspired was removed by his death, even his enemies extolled his valour and military talents, and compared him to the greatest generals who had figured in ancient times, calling him the Chilese Hannibal. To use the words of the abbe Olivarez:-"It is not just to depreciate the merit of one, who, had he been of our nation, we should have vaunted as a hero. If we celebrate the martial prowess of the Spanish Viriatus, we ought not to obscure the fame of the American Lautaro, as both valorously contended in arms for the liberties of their country."
For a long time the Araucanians lamented the untimely fate of the valiant Lautaro, to whom they owed all the success which their arms had hitherto atchieved, and on whose conduct and bravery they entirely relied for the preservation of their independence. His name is still celebrated in their heroic songs, and his actions are still proposed as the most glorious model for the imitation of their youth. Above all others, Caupolican felt and lamented the loss of his valiant associate. Far from thinking he had got free from a rival of his fame, he considered that he had lost his chief coadjutor in the glorious cause of restoring their nation to independence. Immediately on receiving the mournful intelligence, he quitted the siege of Imperial, though reduced to the last extremity, and returned with his army to defend the northern frontiers of Araucania, and to protect his country from the incursions of the Spaniards, as he learnt by his spies that they soon expected a large reinforcement of men and warlike stores from Peru under a new commander.
On learning the death of Valdivia, as formerly related, Philip II. gave charge of the government and conquest of Chili to Alderete, the agent who had been sent by Valdivia into Spain, and furnished him for this purpose with six hundred regular troops. During the voyage to the Tierra Firma, the ship was set on fire by accident, by his sister who was accustomed to read in bed; and of the whole number on board, Alderete and three soldiers alone escaped to Porto Bello. Overcome with grief and disappointment at this melancholy catastrophe, Alderete died soon after in the small island of Taboga in the gulf of Panama. When informed of this disaster, and of the threatening aspect of affairs in Chili in consequence of the untoward events in the Araucanian war, the marquis of Canete, then viceroy of Peru, appointed his son Don Garcia Hurtado de Mendoza, to the vacant government. As this charge had become both important and dangerous, the marquis resolved that his son should be accompanied by such a body of forces as might be able to support his authority, and might enable him successfully to terminate the war against the Araucanians. As the civil dissensions in Peru were now at an end, and that country abounded in military adventurers eager for employment, he was soon able to levy a respectable force of horse and foot for this expedition. The infantry, all well equipped and appointed, with a great quantity of military stores; embarked in ten ships under the command of Don Garcia in person; and the cavalry marched by land under the orders of Garcia Ramon, who was appointed quarter-master-general of Chili.
Don Garcia arrived with his fleet in safety in the Bay of Conception, in the month of April 1557, and came to anchor near the island of Quiriquina, which was chosen as the headquarters as a place of great security. The scanty population of the island attempted to oppose the disembarkation of the troops, but being soon dispersed by the artillery, they retired in their piraguas to the continent. A small number being made prisoners, the governor sent two or three of them with a message to the Araucanians, to inform them of his arrival, and that he was desirous to settle a lasting peace with them on fair terms. In an assembly of the Ulmens to deliberate upon this message, the general opinion was that no propositions ought to be listened to from an enemy who had returned in greater force than ever, under the idea that any terms they might propose would necessarily be treacherous and unfair. Old Colocolo observed, however, that no injury could arise from listening to the proposals of the Spanish governor; and that they even had now a favourable opportunity for obtaining a knowledge of the amount of his force, and for discovering his designs. For this purpose, therefore, he thought it advisable that they should send an intelligent person, under pretence of congratulating the new governor on his arrival, and thanking him for his offer of amicable terms of peace, who might at the same time gain information of whatever he should consider important to regulate their future conduct. Caupolican and most of the older officers adopted this judicious proposal, and the important commission was confided to Millalauco, a person who possessed every requisite for the business confided to his charge.
Millalauco accordingly crossed the narrow strait which separates the island of Quiriquina from the continent, and presented himself to the Spaniards with all the pride which characterises the Araucanian nation. In their turn, the Spaniards were willing to give him a high idea of their military power, and drew out their troops in order of battle for his reception, conducting him to the tent of the governor amidst repeated discharges of their artillery. Not in the least disconcerted by this military parade, Millalauco complimented the governor in the name of Caupolican and the Araucanian chiefs, declaring that they would all be happy in the establishment of an honourable peace, advantageous to both nations, in their desire for which they were solely actuated by motives of humanity, and not by any dread of the Spanish power. Don Garcia, though much disappointed by these vague offers, replied in the same general terms respecting peace; and, after regaling the ambassador in a magnificent manner, he ordered some of his officers to conduct him over the whole encampment, in expectation of intimidating him by displaying the immense military preparations which accompanied him to Chili. This was exactly suited to the wishes of Millalauco, who observed every thing with the utmost attention, though with apparent indifference; and, having taken leave of the Spaniards, he returned to make his report to the assembled chiefs. On receiving an exact report of all that had been seen by their envoy, the Araucanian chiefs gave orders for the establishment of centinels along the coast of their country, to observe and communicate notice of the movements of the Spaniards, and commanded the warriors to prepare for taking the field at the first summons, as they believed a renewal of the war was near and inevitable.
Don Garcia continued inactive almost the whole of the winter in the island of Quiriquina, waiting the arrival of his cavalry from Peru, and for reinforcements which he had required from the cities of Chili. At length, on the night of the 6th August 1557 he privately landed 130 men and several engineers on the plain of Conception, and immediately took possession of Mount Pinto which commands the harbour, where he constructed a fort well garnished with cannon, and surrounded by a deep ditch. This event was immediately communicated to Caupolican, who hastily collected his forces, and passed the Biobio on the 9th of August, and next morning at day-break, a day remarkable in Europe by the defeat of the French at St Quintin, he assailed the new fortress on three sides at once, having sent on in front a body of pioneers to fill up the ditch with fascines and trunks of trees. The assault was long urged with all the furious and obstinate bravery which distinguishes the Araucanians. Numbers mounted the parapet, and some even leapt within the walls, destroying many of the defendants. But the cannon and musquetry of the Spaniards were so skilfully directed, and the slaughter of the assailants so prodigious, that the ditch was filled with dead bodies, serving as bridges for the new combatants who pressed on to replace their slain comrades. Tucapel, impelled by his rash and unparalleled valour, threw himself into the fort, where he slew four of the enemy with his formidable mace, and then made his escape by leaping from a precipice amidst a shower of balls.
