V. Greatly troubled at this was the Cid, and he answered and said, Ill, Sir, would it behove me to counsel you that you should go against the will of your father. You well know that when I went to Cabezon unto him, after he had divided his kingdoms, how he made me swear to him that I would alway counsel his sons the best I could, and never give them ill counsel; and while I can, thus must I continue to do. But the King answered, My Cid, I do not hold that in this I am breaking the oath made to my father, for I ever said that the partition should not be, and the oath which I made was forced upon me. Now King Don García my brother hath broken the oath, and all these kingdoms by right are mine: and therefore I will that you counsel me how I may unite them, for from so doing there is nothing in this world which shall prevent me, except it be death. Then when the Cid saw that he could by no means turn him from that course, he advised him to obtain the love of his brother King Don Alfonso, that he might grant him passage through his kingdom to go against Don García: and if this should be refused he counselled him not to make the attempt. And the King saw that his counsel was good, and sent his letters to King Don Alfonso beseeching him to meet him at Sahagun. When King Don Alfonso received the letters he marvelled to what end this might be: howbeit he sent to say that he would meet him. And the two kings met in Sahagun. And King Don Sancho said, Brother, you well know that King Don Garcia our brother hath broken the oath made unto our father, and disherited our sister Doña Urraca: for this I will take his kingdom away from him, and I beseech you join with me. But Don Alfonso answered that he would not go against the will of his father, and the oath which he had sworn. Then King Don Sancho said, that if he would let him pass through his kingdom he would give him part of what he should gain: and King Don Alfonso agreed to this. And upon this matter they fixed another day to meet; and then forty knights were named, twenty for Castille and twenty for Leon, as vouchers that this which they covenanted should be faithfully fulfilled on both sides.
