Earl Simon almost alone remained unshaken. But his growing influence was seen in the appointment of his supporter, Hugh Despenser, as Justiciar in Bigod's place, while his strength was doubled by the accession of the King's son Edward to his side. In the moment of the revolution Edward had vehemently supported the party of the foreigners. But he had sworn to observe the Provisions, and the fidelity to his pledge which remained throughout his life the chief note of his temper at once showed itself. Like Simon he protested against the faithlessness of the barons in the carrying out of their reforms, and it was his strenuous support of the petition of the knighthood that brought about the additional Provisions of 1259. He had been brought up with Earl Simon's sons, and with the Earl himself his relations remained friendly even at the later time of their fatal hostilities. But as yet he seems to have had no distrust of Simon's purposes or policy. His adhesion to the Earl recalled Henry from France; and the king was at once joined by Gloucester in London while Edward and Simon remained without the walls. But the love of father and son proved too strong to bear political severance, and Edward's reconciliation foiled the Earl's plans. He withdrew to the Welsh border, where fresh troubles were breaking out, while Henry prepared to deal his final blow at the government which, tottering as it was, still held him in check. Rome had resented the measures which had put an end to her extortions, and it was to Rome that Henry looked for a formal absolution from his oath to observe the Provisions. In June 1261 he produced a Bull annulling the Provisions and freeing him from his oath in a Parliament at Winchester. The suddenness of the blow forbade open protest and Henry quickly followed up his victory. Hugh Bigod, who had surrendered the Tower and Dover in the spring, surrendered the other castles he held in the autumn. Hugh Despenser was deposed from the Justiciarship and a royalist, Philip Basset, appointed in his place. [Sidenote: Simon's rising]
