Near the island of Mindanao lies an island called Joló, not very large, but thickly populated with natives, all Mahometans. They number about three thousand men, and have their own lord and king. When Governor Francisco de Sande was returning from his expedition to Borneo, he sent Captain Estevan Rodriguez de Figueroa to Joló. He entered the island and reduced the natives to his Majesty's rule as above related. The natives were apportioned to Captain Pedro de Osseguera for his lifetime, and after his death, to his son and successor, Don Pedro de Osseguera. He asked and collected for several years what tribute they chose to give him, which was but slight, without urging more, in order not to make a general disturbance. While Don Juan Ronquillo was with his camp in Mindanao, the men of Joló, seeing Spanish affairs flourishing, were willing to enjoy peace and pay their tribute; but at the departure of the Spaniards, they became lukewarm again. Captain Juan Pacho, who commanded the presidio of La Caldera in Don Juan Ronquillo's absence, having sent some soldiers to barter for wax, the Joloans maltreated them and killed two of them. Juan Pacho, with the intention of punishing this excess of the Joloans, went there in person with several boats and thirty soldiers. As he landed, a considerable body of Joloans descended from their king's town, which is situated on a high and strongly-fortified hill, and attacked the Spaniards. Through the number of the natives and the Spaniards' inability to make use of their arquebuses, on account of a heavy shower, the latter were routed, and Captain Juan Pacho and twenty of his followers killed. The rest wounded and in flight took to their boats and returned to La Caldera. This event caused great grief in Manila, especially because of the reputation lost by it, both among the Joloans, and their neighbors, the people of Mindanao. Although it was considered necessary to punish the Joloans in order to erase this disgrace, yet as this should be done signally and just then there was not sufficient preparation, it was deferred until a better opportunity. Only Captain Villagra was sent immediately as commander of the presidio of La Caldera, with some soldiers. Having arrived there, they spent their time in pleasure, until their provisions were consumed, and the garrison suffering. They were maintained and supported because of the slight protection that the people of Tampacan felt, knowing that there were Spaniards on the island, and hoped for the arrival of more Spaniards, as Don Juan had promised them, and for punishment and vengeance upon the men of Jolo.
