In the village of Tapacan, on the river of Mindanao, on the twenty-third day of the month of March, one thousand five hundred and seventy-nine, before the illustrious Grabiel de Ribera, captain of infantry for his Majesty in these islands, and before me, Diego Lopez Carreno, notary of the fleet, appeared Pedro Brizeno de Oseguera.  He said that, in fulfilment of the commission and instructions given him by the said captain, to ascend the river with the two vireys and one barangay, accompanied by others, as declared in the said instructions, he went, in prosecution of his voyage, and arrived at the village of Buayen, about four leagues from this village of Tapacan, passing some small uninhabited villages on the way.  When he reached the said village of Buayen carrying a white flag in token of peace, many shouts were raised by his Indians, who called in their own language Siproa, chief of the said town and father-in-law of Limasancay.  Although they shouted, as said, and tried to find some natives in order to confer with them, they could see nothing of them.  On this account they could not inform the natives of the said village of their object.  Therefore he went on to the village of Ybalet, about three leagues from the said town of Buayen.  Carrying his said white flag, he looked for Indians in the said village, and found certain Indians.  He ordered the interpreters with him to summon these Indians to him, declaring that he would not harm them, for he came only to request their peace and alliance, and that they become vassals of King Don Ffelipe, our sovereign, as is Dato Bahandie, chief and native of this river.  When they were asked where the said Limasancay and other chiefs were, they answered that they had left them behind in the village of Buayen and that they had no chief in their village, for he too was hidden with the said Limasancay.  The said Pedro Brizeno de Oseguera also sought provisions in both the villages of Buayen and Ybalet, for the support of the said fleet, but found nothing in either one, for the natives were all hostile, and all their houses had been abandoned.  When the said Indians were asked the above questions, and he saw how scanty was the information derived from them, he [Oseguera] tried to lay certain ambuscades, in order to capture some Indian to have speech with him concerning the said river.  Therefore the two ambuscades were laid, but an Indian could be taken in neither one; for none appeared to be captured, as all had fled, and were so afraid of the soldiers that upon seeing Spaniards in their land they took to the mountains.  Thus retired the Indians who talked with the said Pedro de Oseguera, refusing to come to him.  Since he saw that these two villages—­the most important, so far as he knew, on all this river—­contained no peaceful Indian with whom to treat and from whom he could ascertain what was happening; and that he could find no food, he decided to return to the said captain to advise him of what he said had occurred.  This relation is true, and witnesses present were Ensign Melchor de Torres, Francisco Rodriguez de Salamanca, and San Juan de Cavala.  He affixed his signature, jointly with Captain Grabiel de Ribera.
