XII. The history relateth that at this time while the King was in Galicia, the Moors entered Estremadura, and the people called upon Rodrigo of Bivar to help them. And when he heard the summons he made no delay, but gathered together his kinsmen and his friends, and went against the misbelievers. And he came up with them between Atienza and San Estevan de Gormaz, as they were carrying away a great booty in captives and in flocks, and there he had a brave battle with them in the field; and in fine Rodrigo conquered, smiting and slaying, and the pursuit lasted for seven leagues, and he recovered all the spoil, which was so great that two hundred horses were the fifth, for the whole spoil was worth a hundred times a thousand maravedís. Rodrigo divided the whole among his people without covetousness, and returned with great honour. XIII. Now the greater part of these Moors had been they of Merida, Badajoz, Beja and Evora, and the King was minded to requite them in their own land according to their deeds; and he entered into the heart of their country, carrying with him fire and sword, and pressed them sorely so that they yielded vassalage. Then turning through Portugal, he won the town of Sea, which was upon the western slope of the Serra da Estrella; and also another town called Gamne, the site whereof cannot now be known, for in course of years names change and are forgotten. And proceeding with his conquests he laid siege to the city of Viseu, that he might take vengeance for the death of King Don Alfonso, his wife's father, who had been slain before that city.

King Don Ferrando therefore ordered mantles to be made, and also pavaises to protect his people; and moreover he enjoined them to fasten boards upon their shields, so that the quarrels from the crossbows might not pierce through. And he continued for eighteen days to combat the city, keeping such good watch, that neither could they within receive help from without, nor themselves issue forth; and on the eighteenth day, which was the Vesper of St. Peter's, he won the city by force of arms; and few were they who escaped from the sword of the conquerors, except those who retreated with Alafum into the castle. And on the following day at the hour of tierce they also came to terms, and yielded themselves to his mercy, saving their lives. In this manner was Viseu recovered by the Christians, and never after did that city fall into the hands of the barbarians. And the Moor
