 Matilda gave birth to her third son William on 22 July 1136 at Argentan, and she then operated out of the border region for the next three years, establishing her household knights on estates around the area.Matilda may have asked Ulger, the Bishop of Angers, to garner support for her claim with the Pope in Rome, but if she did, Ulger was unsuccessful.Geoffrey invaded Normandy in early 1136 and, after a temporary truce, invaded again later the same year, raiding and burning estates rather than trying to hold the territory.
