The pacification of Mindanao was undertaken by General Don Juan Ronquillo, who fought with the enemy and eight hundred Terrenatans who came to their assistance. He destroyed and defeated them, killing a number of people. Just when the ruler of Mindanao had offered to make peace, Ronquillo received my order to retire with all his forces to La Caldera, as I did not know of the successful engagement. Before this he had written to me, after having conquered the enemy, that, on account of this success and the improvement of affairs, he would not, even if he should receive an order from me to do so, retire until affairs were more settled. However, when my order arrived, he was in some difficulties, and therefore left that place and retired to La Caldera, which is near. There he built a fort, and before he departed thence, he received my second order to remain at the river of Mindanao, the first place taken, and build a fort there. Not only did he fail to comply with this order, but he has returned with all the troops except a hundred men, leaving everything there exposed to danger. I reported this to the Audiencia, and after they had examined the papers thereof, I resolved to arrest the said Don Juan, accuse him, and after trying him, convict or acquit him. [16] Affairs being in this condition, I sent aid to La Caldera, which was very necessary; and I wrote to the army, encouraging them to persevere in the service of your Majesty. It is now eight months since the rising in the province of Cagayan. The country is in rebellion, but it is true that the encomenderos gave cause for the disturbance by oppressing the natives with tributes, and in other ways. The one who caused most harm in this respect was Don Rodriguez Ronquillo, who died while in prison for this cause. The addition of four reals to the tribute, which was collected last year, also helped to rouse the rebellion. When I considered the serious harm which might result from the uprising in the land, I sent the master-of-camp, Pedro de Chaves, with competent troops, in order that, by means of kind methods, he might reduce them completely to the service of your Majesty. I ordered also that the increase in the tribute be suspended; and this has been done and will be continued until your Majesty is pleased to order otherwise. I think that, until the affairs of this land are better established, say for six years, these four reals should not be collected; but your Majesty will provide according to the royal pleasure.
