And the king believed all that he said, and received him for his vassal, and did him great honour. And all that night they talked together of his secrets, and he made the king believe that he knew a postern by means of which he would put Zamora into his hands. On the morrow in the morning, one of the knights who were in the town went upon the wall, and cried out with a loud voice, King Don Sancho, give ear to what I say; I am a knight, and they from whom I spring were true men and delighted in their loyalty, and I also will live and die in my truth. I say unto you, that from this town of Zamora there is gone forth a traitor to kill you; his name is Vellido Dolfos. Look to yourself therefore and take heed of him. I say this to you, that if evil should befall you by this traitor, it may not be said in Spain that you were not warned against him. And the men of Zamora sent also to the king to bid him beware of Vellido; nevertheless he gave no heed to the warning. And Vellido, when he heard this went to the king, and said, Sir, the old Arias Gonzalo is full crafty, and hath sent to say this unto you, because he knows that by my means you would have won the town. And he called for his horse, feigning that he would depart because of what had been said. But the king took him by the hand and said, Friend and vassal, take no thought for this; I say unto you, that if I may have Zamora, I will make you chief therein, even as Arias Gonzalo is now. Then Vellido kissed his hand and said, God grant you life, sir, for many and happy years, and let you fulfil what you desire. But the traitor had other thoughts in his heart.
