Guy de Boulogne, the Cardinal-Bishop of Porto [e Santa Rufina] and legate of the Holy See, whom the Pope had sent to Spain to make peace between these two kings, as we have related earlier, departed from Ciudad Rodrigo to come and speak to King Enrique. Given that the latter was already besieging Lisbon, the bishop could not enter that area without first meeting the King of Portugal. He arrived in Santarém on Shrove Tuesday, 1 March, not more than nine days after King Enrique had passed that way. He spoke with King Fernando, saying that the Holy Father was deeply perturbed by the war and conflict that the enemy of the human race so often strove to foment between kings who were sons of the Church, principally between those who, being adjacent to the barbarous nations of the infidels might, on account of this hatred and ill will, give the latter an opportunity to destroy the Christian religion. Thus, watching over this with great care, he decided that it was necessary to make peace between those in whom the evil spirit sowed such discord. Since he and King Enrique were two loyal defenders of the faith in Spain, they should not flare up so frequently in war, following unjust impulses, but rather establish friendship and peace between themselves, for the love of that One who so fervently commanded it before He left this world. Another reason for this was that their kingdoms and people should not be weakened by bloodletting.

Once the cardinal had delivered these and other admonitions, which he wisely set forth in his presence, the king replied that he would summon his Royal Council. Agreement on this was reached, since the king had lost hope of the men who were supposed to come from England, on whose account Vasco Domingues had gone there, as you have heard, for these men had been ready for five months, yet because of the bad weather they had not come. Moreover, with his kingdom unfit to carry on the war, he consented for his part to agree to peace, as the cardinal would judge reasonable, without any diminution of his honour.

The cardinal was highly pleased with this reply and left the next day for Lisbon, where he put his arguments to King Enrique in terms similar to those he had put to King Fernando.
