As soon as the governor left Manila, the auditor had plenty to look after, because a squadron of twenty caracoas and other vessels from Mindanao entered the islands as far as the island of Luzon and its coasts, making captures. Having taken some ships bound from Sebu to Manila, they captured ten Spaniards in them, among them a woman and a priest and Captain Martin de Mandia, and they took them off with them. They entered Calilaya, burned the church and all the town, and captured many persons of all classes among the natives. Thence they passed to the town of Valayan [Balayán] to do the same, but the auditor, having received news of the enemy in Manila, had it already in a state of defense with fifty Spaniards and a captain and some vessels. Consequently, they did not dare to enter the town or its bay, but crossed over to Mindoro, where, in the principal town, they captured many men, women, and children among the natives, seizing their gold and possessions, and burning their houses and church, where they captured theprebendary Corral, curate of that doctrina. They filled their own ships, and others which they seized there, with captives, gold, and property, staying in the port of Mindoro as leisurely as though in their own land, notwithstanding that it is but twenty-four leguas from Manila. Captain Martin de Mendia, prisoner of these pirates, offered for himself and the other Spanish captives that, if they would let him go to Manila, he would get the ransom for all, and would take it, or would send it within six months, to the river of Mindanao, or otherwise he would return to their power. The chief in command of the fleet agreed thereto, with certain provisions and conditions, and caused the other captives to write, to the effect that what had been agreed upon might be fulfilled, and then he allowed the captain to leave the fleet. The latter came to the city, and upon receiving his report, the auditor sent munitions, ships, and more men to Valayan than there were there already, with orders to go in pursuit of the enemy without delay, saying that they would find him in Mindoro. Captain Gaspar Perez, who had charge of this in Valayan, did not start so quickly as he should have done in order to find the enemy in Mindoro, for when he arrived he found that he had left that port six days before, laden with ships and booty, to return to Mindanao. Then he went in pursuit of him, although somewhat slowly. The enemy put into the river of a little uninhabited island to get water and wood. Just at that time Governor Don Pedro de Acuña, who was hastily returning to Manila, from the town of Arvalo, where he had learned of the incursion of those pirates, passed. He passed so near the mouth of this river, in two small champans and a virrey, with very few men, that it was a wonder that he was not seen and captured by the enemy. He learned that the enemy was there, from a boat of natives which was escaping therefrom, and then he met Gaspar
