The people loved him and supported him, and he became the real King; having all the power of the government in his own hands, though he was outwardly respectful to King Henry the Third, whom he took with him wherever he went, like a poor old limp court-card. He summoned a Parliament (in the year one thousand two hundred and sixty-five) which was the first Parliament in England that the people had any real share in electing; and he grew more and more in favour with the people every day, and they stood by him in whatever he did.

Many of the other Barons, and particularly the Earl of Gloucester, who had become by this time as proud as his father, grew jealous of this powerful and popular Earl, who was proud too, and began to conspire against him. Since the battle of Lewes, Prince Edward had been kept as a hostage, and, though he was otherwise treated like a Prince, had never been allowed to go out without attendants appointed by the Earl of Leicester, who watched him. The conspiring Lords found means to propose to him, in secret, that they should assist him to escape, and should make him their leader; to which he very heartily consented.

So, on a day that was agreed upon, he said to his attendants after dinner (being then at Hereford), 'I should like to ride on horseback, this fine afternoon, a little way into the country.' As they, too, thought it would be very pleasant to have a canter in the sunshine, they all rode out of the town together in a gay little troop. When they came to a fine level piece of turf, the Prince fell to comparing their horses one with another, and offering bets that one was faster than another; and the attendants, suspecting no harm, rode galloping matches until their horses were quite tired. The Prince rode no matches himself, but looked on from his saddle, and staked his money. Thus they passed the whole merry afternoon. Now, the sun was setting, and they were all going slowly up a hill, the Prince's horse very fresh and all the other horses very weary, when a strange rider mounted on a grey steed appeared at the top of the hill, and waved his hat. 'What does the fellow mean?' said the attendants one to another. The Prince answered on the instant by setting spurs to his horse, dashing away at his utmost speed, joining the man, riding into the midst of a little crowd of horsemen who were then seen waiting under some trees, and who closed around him; and so he departed in a cloud of dust, leaving the road empty of all but the baffled attendants, who sat looking at one another, while their horses drooped their ears and panted.

The Prince joined the Earl of Gloucester at Ludlow. The Earl of Leicester, with a part of the army and the stupid old King, was at Hereford. One of the Earl of Leicester's sons, Simon de Montfort, with another part of the army, was in Sussex. To prevent these two parts from uniting was the Prince's first object. He attacked Simon de Montfort by night, defeated him, seized his banners and treasure, and forced him into Kenilworth Castle in Warwickshire, which belonged to his family.

His father, the Earl of Leicester, in the meanwhile, not knowing what had happened, marched out of Hereford, with his part of the army and the King, to meet him. He came, on a bright morning in August, to Evesham, which is watered by the pleasant river Avon. Looking rather anxiously across the prospect towards Kenilworth, he saw his own banners advancing; and his face brightened with joy.
