The prospect of the ruins of Tucapel and the well regulated array of the adverse army, with the insulting taunts of the enemy, who upbraided them as robbers and impostors, filled the minds of the Spaniards, hitherto accustomed to respect and submission from the Indians, with mingled sentiments of dread and indignation. [Footnote 68: Ovalle does not mention the amount of the army under Valdivia on this occasion, but extends the force of the Araucanians to twenty thousand men.--E.] The two armies continued for some time to observe each other from a small distance. At length the vice-toqui Marientu, who commanded the right wing of the Araucanians, began the engagement by an attack against the left wing of the Spaniards. Bovadilla who commanded in that wing, moved forwards with a detachment to encounter Marientu; but was immediately surrounded, and he and all his men cut to pieces. The serjeant-major, who was dispatched by Valdivia to his succour with another detachment, experienced the same fate. In the mean time, Tucapel, the Apo-ulmen of Arauco, who commanded the left wing of the Araucanians, made a violent attack on the Spanish right wing with his accustomed impetuosity. The battle now became general, and the hostile armies joined in close fight from wing to wing. Animated by the commands and example of Valdivia, who performed at the same time the duty of a valiant soldier and experienced general, the Spaniards by the superiority of their arms overthrew and destroyed whole ranks of the enemy. But, notwithstanding the horrible slaughter produced by the cannon and musquetry of the enemy, the Araucanians continually supplied the places of those who were slain by fresh troops. Three times they retired in good order beyond the reach of the musquetry; and as often, resuming new courage, they returned vigorously to the charge, which they urged with the most determined and persevering valour. At length, after losing a vast number of their men, the Araucanians were thrown into disorder and began to give way; and in spite of every effort of Caupolican, Tucapel, and even of the aged and intrepid Colocolo, to reanimate their courage and rally their disordered ranks, they took to flight. The Spaniards shouted victory! and pressed ardently upon the fugitives, and the battle seemed decidedly won.
