Capture of Fort Balanguingui At dawn on 16 February, taking advantage of the
low tide, which had left the fort linked to the mainland, the regular infantry companies of Asia, la Reina, Segundo Ligero and Fernando VII, plus the 150 veteran
Zamboangan auxiliaries, were landed. At dawn on the 19th the naval forces took their positions. They opened fire at 7:00 AM, at the same time as the land batteries. Near the main fort, on the other side of a thick
coconut grove, there was a minor fort that had inflicted some casualties during the previous engagement. The Spaniards were informed by some fugitives that the pirates were improving the fort's defenses. They also showed Clavería and his men a point from which they could approach to the fort without being seen. On 21 February, Clavería detached a company of the 1st Light Regiment under Colonel Peñarada and some Zamboangan auxiliaries from his naval forces to be landed at the signaled point with the aim of reconnoitering the area or, if possible, capturing the fort. Peñarada and his men, once disembarked, advanced through waist-deep water and managed to surprise the fort. The pirates, lacking military experience, were caught by surprise and fled, leaving the fort and 3 artillery pieces in Spanish hands; another one was captured in a nearby house. After this, two Spanish armed boats and some Zamboangan
vintas entered the island through its channels and set fire to numerous
pancos (
garay) and other vessels used by the pirates, 150 in number. The infantry, meanwhile, cut between 7,000 and 8,000 coconuts, set fire to the seven villages on the island and dismantled and burned the forts. Although the minor vessels of the expedition were detached during the nights to prevent the escape of the remaining pirates, some of them managed to escape to
Jolo or the nearby islands. On the other hand, most of those who had sought refuge in the mangroves died of hunger and thirst. ==Aftermath==
