Having heard what the envoys of the Guaycurús had said, the governor, seeing that so redoubtable a people had come to place themselves in his power with so much submission (a thing that caused much surprise throughout the land), desired them to be informed, through interpreters, that he had come by order of His Majesty to bring all the people to the knowledge of Our Lord, to be Christians and vassals of His Majesty, and to be well treated; if they ceased making war upon the Guaranís he would protect and regard them as friends, and would treat them better than other nations, and that he would restore all the captives taken from them without ransom, both those taken by the Spaniards and Guaranís. And this was thereupon done. When the Guaycurús had received them, they affirmed once more their wish to become vassals of His Majesty, promising obedience and submission, and that they would henceforth not molest the Guaranís, and that they would bring whatever they took, to the town for the provisionment of the Spaniards. Alvar Nuñez was much pleased with their promises, and he distributed gifts and jewels among the chiefs, and peace was cemented.

Since then they have always kept the peace, and whenever the governor sent for them, hastened to obey his commands. Every eighth day they came laden with venison and wild boar, roasted on barbacoas.
