In 1153 he helped arrange the truce between Stephen and Henry Plantagenet, known as the Treaty of Wallingford, which brought an end to The Anarchy.
When the latter ascended the throne as Henry II, he confirmed William's Earldom and gave him direct possession of Arundel Castle (instead of the possession in right of his wife he had previously had). He remained loyal to the king during the 1173 revolt of Henry the Young King, and helped defeat the rebellion.
