Edward and Gloucester both advanced simultaneously to the attack. A storm broke at the moment of the encounter, and the battle was fought in a darkness that obscured the brightness of an August day. Leicester's Welsh infantry broke at once before the charge of the mail-clad horsemen, and took refuge behind hedges and walls, where they were hunted out and butchered after the main fight was over. But the men-at-arms struggled valiantly against Edward's superior forces, though they were soon borne down by sheer numbers. Simon fought like a hero and met a soldier's death. With him were slain his son Henry, his faithful comrade Peter Montfort, the baronial justiciar Hugh Despenser, and many other men of mark. A large number of prisoners fell into the victor's hands, and King Henry, who unwillingly followed Simon in all his wanderings, was wounded in the shoulder by his son's followers, and only escaped a worse fate by revealing his identity with the cry: "Slay me not! I am Henry of Winchester, your King." The marchers gratified their rage by massacring helpless fugitives, and by mutilating the bodies of the slain. Earl Simon's head was sent as a present to the wife of Roger Mortimer; and it was with difficulty that the mangled corpse found its last rest in the church of Evesham Abbey. His memory long lived in the hearts of his adopted countrymen, and especially among monks and friars, who despite the ban of the Church, hailed him as another St. Thomas, for he too had lain down his life for the cause of justice and religion. Miracles were worked at his tomb; liturgies composed in his honour, and an informal popular canonisation, which no papal censures could prevent, kept his memory green. His faults were forgotten in the pathos of his end. His work survived the field of Evesham and the reaction which succeeded it. His victorious nephew learnt well the lesson of his career, and the true successor of the martyred earl was the future Edward I.

No thoughts of policy disturbed the fierce passion of revenge which possessed the victorious marchers. On August 7 Henry issued a proclamation announcing that he had resumed the personal exercise of the royal power. The baronial ministers and sheriffs were replaced by royalist partisans. The acts of the revolutionary government were denounced as invalid. The faithful city of London was cruelly humiliated for its zeal for Earl Simon. The exiles, headed by Queen Eleanor and Archbishop Boniface, returned from their long sojourn beyond sea. With them came to England a new legate, the Cardinal Ottobon, specially sent from the papal court to punish the bishops and clergy that had persisted in their adherence to the popular cause. Four prelates were excommunicated and suspended from their functions, including Berkstead of Chichester and Cantilupe of Worcester. But the aged Bishop of Worcester was delivered from persecution by death; "snatched away," as a kindly foe says, "lest he should see evil days". His nephew, Thomas of Cantilupe, the baronial chancellor, fled to Paris, where he forsook politics for the study of theology. The widowed Countess of Leicester was not saved by her near kindred to the king from lifelong banishment. At last a general sentence of forfeiture was pronounced against all who had fought against Edward, either at Kenilworth or Evesham. There was a greedy scramble for the spoils of victory. The greatest of these, Montfort's forfeited earldom of Leicester, went to Edmund, the king's younger son. Edward took back the earldom of Chester and all his old possessions. Roger Mortimer was rewarded by grants of land and franchises which raised the house of Wigmore to a position only surpassed by that of the strongest of the earldoms.

At first the Montfort party showed an inclination to accept the defeat at Evesham as decisive. Even young Simon of Montfort, who still held out at Kenilworth, considered it prudent to restore his prisoner, the King of the Romans, to liberty. But the victors' resolve to deprive all their beaten foes of their estates, drove the vanquished into fresh risings. The first centre of the revolt of the disinherited was at Kenilworth, but before long the younger Simon abandoned the castle to join a numerous band which had found a more secure retreat in the isle of Axholme, amidst the marshes of the lower Trent. There they held their own until the winter, when they were persuaded by Edward to accept terms. A little later, Simon again revolted and joined the mariners of the Cinque Ports, whose towns still held out against the king, save Dover, which Edward had captured after a siege. Under Simon's leadership the Cinque Ports played the part of pirates on all merchants going to and from England. At last in March, 1266, Edward forced Winchelsea to open its gates to him. He next turned his arms against a valiant freebooter, Adam Gordon, who lurked with his band of outlaws in the dense beech woods of the Chilterns. With the capture of Adam Gordon, after a hand-to-hand tussle with Edward in which the king's son narrowly escaped with his life, the resistance in the south was at an end.

As one centre of rebellion was pacified other disturbances arose. In the spring of 1266, Robert Ferrars, Earl of Derby, newly released from the prison into which Earl Simon had thrown him, raised a revolt in his own county. On May 15, 1266, Derby was defeated by Henry of Almaine at Chesterfield. His earldom was transferred to Edmund, the king's son, already Montfort's successor as Earl of Leicester, and in 1267 also Earl of Lancaster, a new earldom, deriving its name from the youngest of the shires.[1] Reduced to the Staffordshire estate of Chartley, the house of Ferrars fell back into the minor baronage. Kenilworth was still unconquered. Its walls were impregnable except to famine, and before his flight to Axholme young Simon had procured provisions adequate for a long resistance. The garrison harried the neighbourhood with such energy that the whole levies of the realm were assembled to subdue it. After a fruitless assault, the royalists settled down to a blockade which lasted from midsummer to Christmas. The legate, Ottobon, appearing in the besiegers' camp to excommunicate the defenders, they in derision dressed up their surgeon in the red robes of a cardinal, in which disguise he answered Ottobon's curses by a travesty of the censures of the Church.

The blockade soon tried the patience of the barons. It was hard to keep any medieval army long together, and the lords, anxious to go back to their homes, complained of the harsh policy that compelled their long attendance. The royalist host split up into two parties, led respectively by Roger Mortimer and Earl Gilbert of Gloucester. The cruel lord of Wigmore was the type of the extreme reaction. Intent only on vengeance, booty, and ambition, Mortimer clamoured for violent measures, and was eager to reject all compromises. Gloucester, on the other hand, posed as the mediator, and urged the need of pacifying the disinherited by mitigating the sentence of forfeiture which had driven them into prolonged resistance. In the first flush of victory, Edward had been altogether on Mortimer's side, but gradually statecraft and humanity turned him from the reckless policy of the marcher. Edward's adhesion to counsels of moderation changed the situation. While Mortimer pressed the siege of Kenilworth, Edward and Gloucester met a parliament at Northampton which agreed to uphold the policy of 1258 and mitigate the hard lot of the disinherited. A document drawn up in the camp at Kenilworth received the approval of parliament and was published on October 31. The Dictum de Kenilworth, as it was called, was largely taken up with assertions of the authority of the crown, and denunciations of the memory of Earl Simon. More essential points were the re-enactment of the Charters and the redress of some of the grievances against which the Provisions of 1258 were directed. The vital article, however, laid down that the stern sentence of forfeiture against adherents of the fallen cause was to be remitted, and allowed rebels to redeem their estates by paying a fine, which in most cases was to be assessed at five years' value of their lands. Hard as were these terms, they were milder than those which had previously been offered to the insurgents. Yet the defenders of Kenilworth could not bring themselves to accept them until December, when disease and famine caused them to surrender. Despite their long-deferred submission, the garrison was admitted to the terms of the Dictum.

Even then resistance was not yet over. A forlorn hope of the disinherited, headed by John d'Eyville, established themselves about Michaelmas in the isle of Ely, where they made themselves the terror of all East Anglia, plundering towns so far apart as Norwich and Cambridge, maltreating the Jews, and holding the rich citizens to ransom. Early in 1267 the north-country baron, John of Vescy, rose in Northumberland, and violently resumed possession of his forfeited castle of Alnwick. While Henry tarried at Cambridge, Edward went north and soon won over Vescy by the clemency which made the lord of Alnwick henceforth one of his most devoted servants.

More formidable than the revolt of Eyville or Vescy was the ambiguous attitude of Earl Gilbert of Gloucester. Roger Mortimer was once more intriguing against him, and striving to upset the Kenilworth compromise. After a violent scene between the two enemies in the parliament at Bury, Gloucester withdrew to the march of Wales, where he waged war against Mortimer. In April, 1267, he made his way with a great following to London, professing that he wished to hold a conference with the legate. It was a critical moment. Edward was still in the north; Henry was wasting his time at Cambridge; the Londoners welcomed Earl Gilbert as a champion of the good old cause; the legate took refuge in the Tower, and the earl did not hesitate to lay siege to the stronghold. Before long Gloucester was joined by Eyville and many of the Ely fugitives. It seemed as if Gloucester was in as strong position as Montfort had ever won, and that after two years of warfare the verdict of Evesham was about to be reversed.

Edward marched south and joined forces with his father, who had moved from Cambridge to Stratford, near London. Everything seemed to suggest that the eastern suburbs of London would witness a fight as stubborn as Lewes or Evesham. But Gloucester was not the man to press things to extremities, and Edward though firm was conciliatory. He delivered Ottobon from the hands of the rebels,[1] and then arranged a peace upon terms which secured Gloucester's chief object of procuring better conditions for the disinherited. Not only Earl Gilbert but Eyville and his associates were admitted to the royal favour. A few desperadoes still held out until July in the isle of Ely, and Edward devoted himself to tracking them to their lairs. He built causeways of wattles over the fens, which protected the disinherited in their last refuge. When he had clearly shown his superiority, he offered the garrison of Ely the terms of the Dictum de Kenilworth. With their acceptance of these conditions the English struggle ended, in July, 1267, nearly two years after the battle of Evesham.
