[As soon as the Spaniards abandoned the fort of Lábo in Paragua, the Moro pirates renewed their incursions. When Zamboanga was reestablished, they attempted to capture it, but were repulsed with loss. In 1721-23 expeditions were sent out against the Moros, but they failed to accomplish anything. [5] The sultan of Joló sent an ambassador to Manila in 1725, to form a treaty of peace with the Spaniards; this was accomplished in the following year at Joló, the Spanish envoy being Miguel Arajón, the alcalde-mayor of the Parián at Manila. By this treaty, among other provisions, the island of Basilan was restored to Spain. Nevertheless, soon afterward the perfidious Moros made several raids against Indian villages, captured many vessels and burned them, and committed many acts of cruelty,--the worst probably being the case of a vessel from Cebú, whose crew were all killed by the pirates, who then tortured to death the Spanish captain. Later, letters were received from Radiamura (the son of Maulana) and other friendly chiefs in Mindanao, asking for prompt action by the Spaniards against the Moro pirates, who, they claimed, were threatening them with attack because of their friendship to the Spaniards. Governor Torre Campo organized a punitive expedition for this purpose, but the royal treasury was so depleted that the costs had to be met by donations from the citizens of Manila and Cavite. The armada was placed under command of Juan Angel de Leaño, with directions to surrender the vessels and men to General Juan de Mesa when they should reach Iloilo; and the governor gave the commanders definite instructions, and powers for forming a treaty with the "kings" of Joló and Mindanao. "The result of this expedition is not definitely stated, except that it was successful; the fort of La Sabanilla at Tuboc was taken, and a great number of the rabble [canalla] were slain, and among them some princes and datos (the remembrance of which still continues among them, to the honor of our arms); and a treaty for the cessation of hostilities was drawn up, which the Moros, well punished, asked for." (Concepción, Hist. de Philipinas, x, pp. 134-157, 184-198.)] [On July 23, 1726, the galleon "Santo Christo de Burgos" was driven by a storm on the rocks at Ticao, a long, narrow island adjoining San Bernardino Strait, and so badly wrecked that it could not be repaired. The auditor Julian de Velasco was on board the vessel, on his way to Mexico; as the official of highest rank on the ship, he held a conference with the officers, pilots, seamen, and other persons of experience, and it was decided (after several vain efforts had been made to save part of the cargo) to burn the ship and its contents, great part of which were ruined by the water. This was a great loss to the citizens of Manila, as all their investments for this year were thus destroyed. (Concepción, Hist. de Philipinas, x, pp. 157-167.)]
