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.
Simon's rising
The news of this counter-revolution reunited for a moment the barons. Gloucester joined Earl Simon in calling an autumn Parliament at St. Alban's, and in summoning to it three knights from every shire south of Trent. But the union was a brief one. Gloucester consented to refer the quarrel with the king to arbitration and the Earl of Leicester withdrew in August to France. He saw that for the while there was no means of withstanding Henry, even in his open defiance of the Provisions. Foreign soldiers were brought into the land; the king won back again the appointment of sheriffs. For eighteen months of this new rule Simon could do nothing but wait. But his long absence lulled the old jealousies against him. The confusion of the realm and a fresh outbreak of troubles in Wales renewed the disgust at Henry's government, while his unswerving faithfulness to the Provisions fixed the eyes of all Englishmen upon the Earl as their natural leader. The death of Gloucester in the summer of 1262 removed the one barrier to action; and in the spring of 1263 Simon landed again in England as the unquestioned head of the baronial party. What immediately forced him to action was a march of Edward with a body of foreign troops against Llewelyn, who was probably by this time in communication if not in actual alliance with the Earl. The chief opponents of Llewelyn among the Marcher Lords were ardent supporters of Henry's misgovernment, and when a common hostility drew the Prince and Earl together, the constitutional position of Llewelyn as an English noble gave formal justification for co-operation with him. At Whitsuntide the barons met Simon at Oxford and finally summoned Henry to observe the Provisions. His refusal was met by an appeal to arms. Throughout the country the younger nobles flocked to Simon's standard, and the young Earl of Gloucester, Gilbert of Clare, became his warmest supporter. His rapid movements foiled all opposition. While Henry vainly strove to raise money and men, Simon swept the Welsh border, marched through Reading on Dover, and finally appeared before London.
Mise of Amiens
The Earl's triumph was complete. Edward after a brief attempt at resistance was forced to surrender Windsor and disband his foreign troops. The rising of London in the cause of the barons left Henry helpless. But at the moment of triumph the Earl saw himself anew forsaken. The bulk of the nobles again drew towards the king; only six of the twelve barons who had formed the patriot half of the committee of 1258, only four of the twelve representatives of the community at that date, were now with the Earl. The dread too of civil war gave strength to the cry for a compromise, and at the end of the year it was agreed that the strife should be left to the arbitration of the French king, Lewis the Ninth. But saint and just ruler as he was, the royal power was in the conception of Lewis a divine thing, which no human power could limit or fetter, and his decision, which was given in January 1264, annulled the whole of the Provisions. Only the Charters granted before the Provisions were to be observed. The appointment and removal of all officers of state was to be wholly with the king, and he was suffered to call aliens to his councils if he would. The Mise of Amiens was at once confirmed by the Pope, and, crushing blow as it was, the barons felt themselves bound by the award. It was only the exclusion of aliens--a point which they had not purposed to submit to arbitration--which they refused to concede. Luckily Henry was as inflexible on this point as on the rest, and the mutual distrust prevented any real accommodation.
Battle of Lewes
But Henry had to reckon on more than the baronage. Deserted as he was by the greater nobles, Simon was far from standing alone. Throughout the recent struggle the new city governments of the craft-gilds, which were known by the name of "Communes," had shown an enthusiastic devotion to his cause. The queen was stopped in her attempt to escape from the Tower by an angry mob, who drove her back with stones and foul words. When Henry attempted to surprise Leicester in his quarters at Southwark, the Londoners burst the gates which had been locked by the richer burghers against him, and rescued him by a welcome into the city. The clergy and the universities went in sympathy with the towns, and in spite of the taunts of the royalists, who accused him of seeking allies against the nobility in the common people, the popular enthusiasm gave a strength to the Earl which sustained him even in this darkest hour of the struggle. He at once resolved on resistance. The French award had luckily reserved the rights of Englishmen to the liberties they had enjoyed before the Provisions of Oxford, and it was easy for Simon to prove that the arbitrary power it gave to the Crown was as contrary to the Charter as to the Provisions themselves. London was the first to reject the decision; in March 1264 its citizens mustered at the call of the town-bell at Saint Paul's, seized the royal officials, and plundered the royal parks. But an army had already mustered in great force at the king's summons, while Leicester found himself deserted by the bulk of the baronage. Every day brought news of ill. A detachment from Scotland joined Henry's forces. The younger De Montfort was taken prisoner. Northampton was captured, the king raised the siege of Rochester, and a rapid march of Earl Simon's only saved London itself from a surprise by Edward. But, betrayed as he was, the Earl remained firm to the cause. He would fight to the end, he said, even were he and his sons left to fight alone. With an army reinforced by 15,000 Londoners, he marched in May to the relief of the Cinque Ports which were now threatened by the king. Even on the march he was forsaken by many of the nobles who followed him. Halting at Fletching in Sussex, a few miles from Lewes, where the royal army was encamped, Earl Simon with the young Earl of Gloucester offered the king compensation for all damage if he would observe the Provisions. Henry's answer was one of defiance, and though numbers were against him, the Earl resolved on battle. His skill as a soldier reversed the advantages of the ground; marching at dawn on the 14th of May he seized the heights eastward of the town, and moved down these slopes to an attack. His men with white crosses on back and breast knelt in prayer before the battle opened, and all but reached the town before their approach was perceived. Edward however opened the fight by a furious charge which broke the Londoners on Leicester's left. In the bitterness of his hatred for the insult to his mother he pursued them for four miles, slaughtering three thousand men. But he returned to find the battle lost. Crowded in the narrow space between the heights and the river Ouse, a space broken by marshes and by the long street of the town, the royalist centre and left were crushed by Earl Simon. The Earl of Cornwall, now King of the Romans, who, as the mocking song of the victors ran, "makede him a castel of a mulne post" ("he weened that the mill-sails were mangonels" goes on the sarcastic verse), was taken prisoner, and Henry himself captured. Edward cut his way into the Priory only to join in his father's surrender.
Simon's rule
The victory of Lewes placed Earl Simon at the head of the state. "Now England breathes in the hope of liberty," sang a poet of the time; "the English were despised like dogs, but now they have lifted up their head and their foes are vanquished." But the moderation of the terms agreed upon in the Mise of Lewes, a convention between the king and his captors, shows Simon's sense of the difficulties of his position. The question of the Provisions was again to be submitted to arbitration; and a parliament in June, to which four knights were summoned from every county, placed the administration till this arbitration was complete in the hands of a new council of nine to be nominated by the Earls of Leicester and Gloucester and the patriotic Bishop of Chichester. Responsibility to the community was provided for by the declaration of a right in the body of barons and prelates to remove either of the Three Electors, who in turn could displace or appoint the members of the Council. Such a constitution was of a different order from the cumbrous and oligarchical committees of 1258. But it had little time to work in. The plans for a fresh arbitration broke down. Lewis refused to review his decision, and all schemes for setting fresh judges between the king and his people were defeated by a formal condemnation of the barons' cause issued by the Pope. Triumphant as he was indeed Earl Simon's difficulties thickened every day. The queen with Archbishop Boniface gathered an army in France for an invasion; Roger Mortimer with the border barons was still in arms and only held in check by Llewelyn. It was impossible to make binding terms with an imprisoned king, yet to release Henry without terms was to renew the war. The imprisonment too gave a shock to public feeling which thinned the Earl's ranks. In the new Parliament which he called at the opening of 1265 the weakness of the patriotic party among the baronage was shown in the fact that only twenty-three earls and barons could be found to sit beside the hundred and twenty ecclesiastics.
