Valdivia, though he had been present in many battles, both in Europe and America, was astonished at the valour and military skill of this new enemy, and declared he had never been exposed to such imminent danger in the whole course of his military service. As he expected to be soon attacked again, he immediately proceeded to construct a strong fortification for the protection of his new city; and in fact, the Araucanian confederacy was no sooner informed of the defeat and death of their general Aillavalu, than a new and more numerous army was ordered against the Spaniards, under the command of _Lincoyan_, who was elected to the vacant office of supreme toqui. From his gigantic stature, and frequent displays of courage, this officer had acquired great reputation among his countrymen; but, though well suited for a subaltern officer, he was timid and irresolute in the supreme military command, and greatly disappointed the expectations which had been formed from his former behaviour. Having marshalled his army in three divisions, Lincoyan marched in 1551 to attack the Spaniards under Valdivia, who still remained at Conception, occupied in building and fortifying the new city. The Spaniards were so much alarmed by the approach of the Araucanian army, that after confessing themselves, they took shelter under the cannon of their fortifications, where the Araucanians boldly assailed them. But, finding the first assault unsuccessful, Lincoyan became apprehensive of losing the army which had been committed to his charge, and ordered a precipitate retreat, to the great surprise of Valdivia, who was apprehensive of some stratagem, and did not venture upon attempting a pursuit. When it was discovered that the enemy had actually retreated, the Spaniards considered their flight as a special favour from heaven, and some even alleged that they had seen the apostle St James, mounted on a white horse, waving a flaming sword and striking terror into their enemies. But the only miracle on this occasion proceeded from the timid circumspection of Lincoyan.
