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.
But then Benalfagi, who was the Lord of many lands in Estremadura, gathered together a great power of the Moors and built up the walls of Montemor, and from thence waged war against Coimbra, so that they of Coimbra called upon the King for help.
