evil should befall you by this traitor, it may not be said in Spain
that you were not warned against him. Now the name of this knight was
Bernal Dianez de Ocampo. And the men of Zamora sent also to the King to
bid him beware of Vellido, and the king took their warning in good
part, and sent to say unto them, that when he had the town he would
