[Torrubia enumerates the armed naval expeditions sent against the Moro pirates during 1721–34, as follows: (1) An armada commanded by Antonio de Roxas sailed from Manila on July 10, 1721; it seems to have accomplished little, but cost the treasury much. (2) Another was commanded by Andrés Garcia; he fought with a Moro fleet—date not given, but probably in 1722—at Negros Island, and won a notable victory. (3) In 1723 a fleet set out under command of Juan de la Mesa y Aponte, warden of Fort Santiago at Manila; they went to Mindanao and captured from the Moros the fort at La Sabanilla, “slaying an immense number of that rabble, and among them several princes and datos.” (4) In February, 1731, four galleys were sent from Manila under command of Ignacio Irriberri; at Zamboanga they collected the vessels already there—two fragatas, four despatch-boats or champans, one taratana, one falua, eight caracoas of Bisayans and two others of Lutaos—and went to attack Joló, at which they found six forts defended by cannon. Here they had a fierce battle with the Moros, of whom many were slain, including two datos; then they ravaged the adjacent island of Talobo, destroying its salt-works (“which are the entire livelihood of that people”); and laid waste the district of the dato Salicaya, who, with many of his people, was slain. In the same year Captain Pedro Zacharias Villareal, with some vessels of the same fleet, attacked the island of Capual, near Joló, and burned three villages and many boats, and ravaged the fields, destroying their cattle and the salt-works there. (5) In November, 1731, Zacharias was sent by Valdés Tamon with a squadron from Manila to Zamboanga; at that very time, the sultan of Mindanao, Maulana Diafar Sadibsa, was asking aid from the Spaniards against his tributary Malinog, who had rebelled against him and had secured the support of more than thirty of the principal villages on the Rio Grande of Mindanao. This rebellion was caused by Malinog’s refusal to obey Maulana’s demand that he restore to the Spaniards the captives and spoil which Malinog, in conjunction with the Joloans, had carried away in 1722–23 from Negros and Panay. It was learned that Malinog was negotiating with the Dutch for succor, which they were inclined to grant him. At a council of war (in which the Jesuits were prominent) held in Zamboanga, it was decided to send Zacharias with a fleet to Tamontaca, to aid Maulana and punish Malinog. The latter’s fort—which, like that in Joló, was constructed by a Dutch engineer—at the entrance to his river, was captured by the united forces and large amounts of military supplies were destroyed. Two leguas further up the river, they attacked Malinog’s principal town, defended by six forts; many of the Moros (including their general, Tambul) were slain, three of their villages were burned, and their lands devastated. Returning to Zamboanga, the Spaniards harried the coasts of Joló and Basilan, so thoroughly that, later, “in order to terrify the Moros, it is only necessary to say, ‘Here comes Zacharias.’” (6) In January, 1733, a fleet under Juan Antonio Jove went to aid Maulana; but Malinog made a sudden attack on Tamontaca, which he destroyed with fire and sword, and slew Maulana, whereupon the Spaniards, disheartened, returned to Manila. (7) Maulana’s successor, Radiamura, asked aid from Manila, which was granted; the citizens subscribed more than nine thousand pesos in silver, and a fleet of forty-eight vessels was equipped. Under command of Francisco de Cardenas Pacheco and Captain (soon afterward made sargento-mayor) Zacharias, this fleet left Zamboanga on February 18, 1734, and went to Tamontaca. At Tuboc they attacked the sultan of Tawi-Tawi, but the Bisayan auxiliaries of the Spaniards fled, panic-stricken, and the Moro allies of the sultan swarmed in upon the Spaniards, compelling them to retreat. They then went against Malinog at Sulangan; at sight of the Spanish fleet, he set fire to his village and forts, and fled up the river to Libungang—a place which was strongly fortified by both nature and art. A fierce assault was made on this stronghold, but the Moros could not be dislodged; they killed many Spaniards with their unceasing discharge of balls and small weapons, and finally, by poisoning the water-supply, compelled the Spaniards to raise the siege. Then the latter went to Sulungan, and remained there until that place was well fortified, and the passage of the river securely closed to Malinog, who was thus shut in from his allies the Joloans and Camucones. On April 20, Radiamura was solemnly crowned as king by the Spaniards; and he agreed to allow the entrance of Christian missionaries, the building of churches, and the establishment of Spanish forts and garrisons, in his territories; also to acknowledge his vassalage to Spain by furnishing a quantity of wax, cacao, and other products of the country. Afterward, Zacharias made a raid on Basilan, devastated the lands, and seized much and rich booty; “so great was the spoil of the ‘enchanted island’ that, when the men had laden our armada and the captured vessels [which numbered over three hundred], they had to burn many articles because they could not carry them away.” (Torrubia, Dissertacion, pp. 68–90.)

[The Marqués de Torre Campo, after eight years of clement and upright government, was succeeded by Fernando de Valdés y Tamón, a knight of the Order of Santiago, who took possession of his office on August 14, 1729. As an experienced and able soldier, he gave his first attention to the fortifications and military equipment of Manila, which had been sadly neglected. He tried to purchase 1,500 guns with bayonets, but the Dutch refused to sell him these firearms. In May, 1730, the pirates of Joló sent out a large expedition, with 3,000 men, against the islands of Palawan and Dumaran, where they plundered the villages and carried away many captives. They besieged the fort at Taytay (the principal town in that part of Palawan) during twenty days, but were obliged to retire with considerable loss, including some of their datos. As it was evident that the islands could have no peace or safety until severe punishment was inflicted on these pirates, an expedition with over 600 men was sent from Manila in February, 1731, under the command of General Ignacio de Iriberri. This force attacked the town of Joló, which was well defended with forts and artillery; and after a fierce contest the Spaniards captured the place, and burned the houses and boats of the Moros. They also ravaged the islands of Talobo and Capual, near Joló, and destroyed the salt-works there, from which the pirates obtained much wealth; and returned to Manila in the month of June. A prominent chief of Mindanao, named Malinog, had revolted against Maulana Diafar, sultan of Tamontaca, securing the aid of many datos on the Rio Grande, and negotiating with the Dutch for their aid; in November, 1731, a small squadron was sent from Manila, in answer to Maulana’s petition for aid against the rebels; with the aid of the Spaniards the rebels were routed, their forts destroyed, and their villages and plantations ravaged and burned. Malinog, however, kept up the contest, so that another Spanish expedition was sent (January, 1733) against him; but while his town was besieged by the Tamontacans and the Spaniards he slipped away with 300 pirogues and invaded Tamontaca, where Maulana was slain by his foes.[6] His son Amuril asked Governor Valdés y Tamón for aid against Malinog, which was granted; and in February 1734 an expedition left Zamboanga under command of General Francisco Cárdenas Pacheco, who placed a detachment of the armada under Pedro Zacarías Villarreal. Their campaign against the Moros was bravely fought, but was only partially successful, on account of the fierceness and overwhelming numbers of the Moros. The latter committed numerous depredations wherever and whenever they could find opportunity, and the Manila government took measures for the erection of lookout towers and fortifications at the coast villages, and for sending coastguard galleys and other vessels to the points most likely to be menaced by the pirates, so as to be ready to meet or follow up any Moro vessels that might attack the Indian villages or Spanish forts. In 1735, 2,000 Joloans and Mindanaos attacked the fort at Taytay, but they were finally repulsed with great loss. In this conflict, as often on like occasions, the native soldiers in the garrison were encouraged and incited by the friars in whose spiritual charge they were, to resist the fierce foe who attacked them.[7] In 1735, Mahamad Ali-Mudin was raised to the sultanate of Joló, in virtue of the abdication of his father Maulana. The latter plotted to obtain possession of the fort at Zamboanga by treason, but the scheme was unsuccessful; the news of this so angered Maulana (who was then ill) that he hastened his own death. The new sultan of Joló professed (1736) friendship to the Spaniards, and even joined them in a campaign against the Tiron pirates; but in secret he encouraged the latter, and sent them warning of the movements against them. (Montero y Vidal, Hist. de Filipinas, i, pp. 438–452; his account is largely taken from Concepción’s Hist. de Philipinas, x, pp. 198–238, 337–375.)]

[On June 18, 1733, the royal magazines at Manila were destroyed by fire, with all their contents, which included the supplies for the two vessels which were soon to go to Acapulco. The royal treasury had not the funds to make good this loss, and the galleons must sail at a certain time, in order to secure favorable winds; the governor therefore appealed to the citizens and merchants for help to meet the expenses of equipping the vessels. They responded with a donation of 30,000 pesos, which the governor duly reported to the king, asking that in view of the zeal and loyalty thus displayed by the citizens their interest might be cared for in the pending dispute regarding the Manila-Acapulco commerce. The losses sustained in the above fire were estimated by the royal officials at 66,807 pesos. (Concepción, Hist. de Philipinas, x, pp. 226–230.)]
