Relation of how Gomez Perez Dasmariñas, governor of the Philipinas, heard that the province of Tuy was unexplored, which induced him to undertake its exploration; and his authorization to his son, Don Luis Perez, to make the said exploration.

Governor Gomez Perez Dasmariñas learned from certain religious of the Order of St. Augustine that this island of Luzon, where is located the capital of all the islands—namely, the city of Manila—was not yet completely explored or conquered, as it was suspected that the interior contained hostile and very valiant Indians; that the country was exceedingly productive, temperate, and fertile, and contained many cattle; that it was called the province of Tuy, and was contiguous on one side, as was imagined, to the farthest territory of the Sanvales [i.e., Zambales], and on the other to the source of the river flowing to Cagayan. This last was one of the reasons why Cagayan had always been hostile, and the Indians never weary of continuing the war; for they went inland by way of the river—where, the Spaniards did not know, beyond the fact that they were supplied from that region with provisions and other things, which the Spaniards took from them, in order to reduce them. When the governor asked the Spaniards the reason for so much neglect—why, for twenty years, they had made no attempt to go inland, since that was so important for the pacification of what was discovered—they did not know what to answer, except that a certain number of Spaniards had once ascended the Cagayan River, seven of whom were captured by the Indians. Since then, they said, the ascent had not been again attempted. The governor, having found that, although he tried to obtain from the Spaniards more definite information of the nature and characteristics of the said new land of Tuy, they were unable to give him any account of the said province, tried to gain information of that land by means of some of the natives. This he did by sending two Indians thither with all secrecy. One of them only, the more clever of the two, reported that beyond the farthest village of the Sanbales toward the north, he had learned with certainty that there were three or four villages of very well-disposed Indians, and that the country was excellent. He recounted some details of it, adding that he believed that the river of that province ended in Cagayan. The governor realized the importance of the expedition from this relation, and through two Indian women (by the medium of two interpreters from that land); and saw that the sure pacification of all Cagayan and of this island of Luzon, and the removal of errors by ascertaining with certainty what it contained, depended on that expedition. There was also reasonable ground, from the indications and reports adduced, for expecting that there must be many undiscovered Indian settlements. Accordingly he determined—although against the advice of the Spaniards who had lived longest in the country, who declared that the country was thoroughly explored and that there was nothing else to explore in it—to send his son, Don Luis Dasmariñas, thither to make the said new exploration of Tuy. The latter was to be accompanied by the captain and sargento-mayor, Juan Xuarez Gallinato, Captain Don Alonso de Sotomayor, and Captain Cristoval de Asqueta (all old residents), and seventy soldiers, most of whom the governor had brought new with him from España, besides certain of the governor’s servants and some other soldiers who had been here in the country. The said Don Luis was accompanied also by two fathers, religious of the Order of St. Augustine, for the greater justification both of the expedition and of the mildness with which he was to proceed. One was the definitor, Fray Diego Gutierrez, and the other, Fray Mateo de Peralta. Juan de Argumedo, and even many soldiers and others, private persons, who came to the governor to ask permission to go with his son, accompanied Don Luis halfway, but halted in La Pampanga, as they did not appear to be needed. To these latter the governor refused the permission, although very much pleased at seeing so great willingness and readiness in all of them to follow his son, and to take part in this or in any other expedition that might offer, and which for lack of system and resolute action could not be continued throughout, as was fitting, according to the arrangement and outcome of affairs. The title of lieutenant to the captain-general was given to the said Don Luis, with the following orders and instructions. He was instructed especially to tell his father in detail all that should happen.

Warrant of Don Luis Perez Dasmariñas for the exploration of the province of Tuy.

Gomez Perez Dasmariñas, etc. Inasmuch as I have been informed by the relations of persons of credit that about three days’ journey from Mungabo, a village of La Pampanga, lies a densely-settled district, very fertile and prosperous, called Tuy, which extends to the confines of the province of Cagayan; and although many things have been told of it and of its vast population, no exploration has as yet been made therein, nor has possession been taken of it in his Majesty’s name; and although his Majesty’s royal and holy intention is the preaching of the holy gospel; and since—so that these nations may learn of the true God, and be saved by means of our holy Catholic faith—it is advisable to explore and colonize the said province, and establish therein the holy Catholic faith and obedience to his Majesty, for which it is necessary to send religious to preach the law of God and the Christian doctrine, and soldiers to accompany and protect the religious: Therefore, by this present, I order my son, Don Luis Dasmariñas, hereby appointed by me as lieutenant of the captain-general in this camp, to undertake the exploration, entrance, and new pacification of the said province and district of Tuy accompanied by the said fathers, religious of the said Order of St. Augustine, and those soldiers who will be assigned to him. He shall fulfil and observe the instructions that shall be given him with this my order, in the expedition and exploration. For all the above and for all annexed and pertaining to it, I grant him authority and power in due legal form, and as I possess and hold it from his Majesty. Given at Manila, July three, one thousand five hundred and ninety-one.

Gomez Perez Dasmariñas

By the governor’s order: Juan de Cuellar

Instructions for this expedition given by Gomez Perez Dasmariñas to his son.

Granting that one of the reasons for the hatred and hostility of the Indians toward us is the collection of tributes, especially when it is not accomplished with suitable mildness and moderation, this question shall by no means be discussed with them in the beginning. Rather, if the Indians should be fearful of what should be collected from them, and should place obstacles in the way of their reduction and our principal end, that of their conversion, good hopes shall be offered them that all satisfaction shall be accorded them in this matter, and that the tribute shall be only what they choose to give.

2. You shall under no consideration allow any soldier to seize any gold or any other article of value from any Indian, in case that any of the said Indians should flee through fear or any other reason, and abandon their gold or other property to the power of the soldiers. It shall immediately be sent to its owner, to show them, as above stated, that the expedition is not being made there for their gold. On the contrary, you shall endeavor, before the Indians, to attach very slight importance to gold, alleging that it has but little value and esteem among us. In all the above, and in whatever else may come to your notice, you shall always govern yourself by, and conform as far as possible to, the opinion of the undersigned members of the council of war. You shall endeavor to direct everything that you do with the great energy and resolution that can and should be expected from your wisdom and prudence. In all things you shall regard the service of God and that of the king our sovereign.

3. Rivers, so far as possible, shall be crossed only on well-made rafts, and without any danger to the soldiers or overturning them in the water.
