Esteybar then equipped a small squadron of caracoas and vintas, which departed from Zamboanga on January 1, 1658, resolved to chastise the pirate severely. He spread the report that they were going to Sibuguey. He reached that river in seven days and, placing part of his forces in charge of Sargento-mayor Itamarren, he destroyed the village of Namucan, and at Luraya burned many boats. Four pilans captured the joanga which had carried Father López to Simuay, manned by Moros from Mintun. Suddenly changing his course, he took the route to Punta de Flechas, in order to go to the capital of Corralat, but sent beforehand thirty Spaniards, with Captain Don Pedro de Viruega, to the district of Butig. Its chief Matundin, at the head of five hundred men, was defeated, the grain-fields ravaged, and the village reduced to ashes. The tilled land of this district was exceedingly rich, since it is the principal source of supply for rice in Mindanao. Great damage was also done in La Sabanilla by Captain Don Juan González Carlete. On the nineteenth of January the squadron encountered a large Dutch ship surrounded by some pirate vessels. Esteybar attempted to secure a free passage without bringing on a contest, to which end he hoisted a white flag; but the commander of the Dutch ship displayed a red flag, firing all his cannon against the Spanish vessels. Then, without heeding the superiority of the enemy, Bobadilla came against the ship, all his men rowing as hard as they could; and Esteybar attacked it at the stern. The Spaniards then were going to board the ship with a rush, when a ball fired from the vessel of Esteybar set on fire the Santa Barbara [i.e., powder-magazine] of the Dutch ship, thus blowing it into pieces. Only twenty-four of its crew survived, and these were drawn out of the sea and made prisoners. Esteybar continued his voyage to Simuay, the bar of which was fortified with heavy stockades; moreover, at its ends were two forts, garrisoned by Malays, Macassars, and Dutchmen. This did not frighten Esteybar, and he made preparations to capture the posts of the enemy, in spite of advice to the contrary from his captains. While he was deciding the best method of accomplishing this, he passed with his squadron to the river of Buhayen, sending in by one of its entrances the valiant Bobadilla with some vessels, and by the other Sargento-mayor Itamarren. The former sacked the villages and ravaged the grain-fields of Tannil and Tabiran, the latter those of Lumapuc and Buhayen; they destroyed a powerful armada which had been prepared for raiding the islands, and carried away as spoil many versos, muskets, campilans, crises, and all kinds of weapons.
