Came of age in 1194/5. He was early embittered against King John by being compelled to surrender the Barony of Frontboeuf, which Henry I had conferred upon his great grandfather, Sir Nigel d'Aubigny. That, and the aid exacted from his vassals, enraged him. We note in Magna Charta, Article 16, that a lord is forbidden to demand more service than a fief owes. Perhaps William was influential in getting this clause accepted. The debt was probably exacted because Mowbray, upon the accession of King John, was tardy in pledging his allegiance and at length swore fealty only on condition that "the King should render to every man his right." At the breaking out of the Baronial war, he was governor of York Castle, and it is not surprising that he at once sided with the Barons against King John, and was one of the most forward among them.
He was a party to the "Covenant for holding the City and Tower of London," and one of those whom the Pope excommunicated. He continued in arms after the death of King John, and in the Battle of Lincoln he was taken prisoner. His lands were confiscated and bestowed upon William Marshall, Jr., the Surety, but he was subsequently allowed to redeem them. After this he attached himself to King Henry III. He died in 1223/4 at his Castle in the Isle of Axholme.1
