[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,
