when he was leaving the island of Mindanao already pacified—­the chiefs, with whom he had used gentle means, that they might all be more contented, having again rendered submission to his Majesty; and likewise as the king of Jolo again rendered obedience and submission.  Confiding in this, Captain Cristoval Villagra, whom Don Juan Ronquillo had appointed commander of the garrison of La Caldera, had sent thirty soldiers to the island of Jolo for supplies.  They found at this time in Jolo a Mindanao chief—­an uncle of the king of Mindanao, and a brother-in-law of the king of Jolo—­who had been driven out of Mindanao because he was rebellious.  He treacherously killed thirteen Spanish soldiers.  When news of this was brought, Juan Pacho was sent to take the troops of La Caldera in charge; and, when it should seem best to him, to try to inflict punishment on the king of Jolo.  Having gone out to inflict the said punishment with six hundred Spaniards, the enemy unfortunately killed the said Juan Pacho and twenty-nine Spaniards, the rest of them retiring without any success.  This news having come to the governor, he sent in place of Juan Pacho Captain Toribio de Miranda, a person in whom he had entire confidence, with an order not to attempt any punishment until he had force enough for it.  After this Captain Toribio de Miranda arrived at La Caldera on the twenty-sixth of August in ninety-nine.  When the garrison was given into his charge he put the defensive works in order; and with the arms which he brought, and those which he found in the fort, he armed all the troops, amounting to a hundred and fourteen soldiers.  As directed by an order of the governor, he sent a chief of the Pintados to Mindanao with letters to the chiefs of the island, in which he informed them that they would be protected, favored, and upheld in justice, as vassals of his Majesty, and that with this object a garrison had been placed in La Caldera; and that to aid in maintaining it, and in covering the expenses which they had caused in the war by their disobedience, the largest possible quantity of tributes would be collected for his Majesty, and that he would send for them shortly—­which had not been done earlier because the Mindanaos had been so spent and afflicted.  Having arrived on the second of September at the river of Mindanao, and delivered his despatch, this chief was well received, and found the people in the settled state in which General Don Juan Ronquillo had left them.  Adiamora, the main chief of Mindanao, in the name of them all, sent him back on the fifteenth of the said month, offering to give to his Majesty all the tribute which they could collect.
