a mill, where he soon made an ignominious
surrender. Henry himself lost his horse under him and was forced to
yield himself prisoner to Gilbert of Gloucester. The mass of the army
was forced back on to the town and priory, which were occupied by the
victors. Scarcely was their victory assured when Edward and the
marchers came back from the pursuit of the Londoners. Thereupon the
battle was renewed in the streets of the town. It was, however, too
late for the weary followers of the king's son to reverse the fortunes
of the day. Some threw themselves into the castle, where the king's
standard still floated; Edward himself took sanctuary in the church of
the Franciscans; many strove to escape eastwards over the Ouse bridge
or by swimming over the river. The majority of the latter perished by
drowning or by the sword: but two compact bands of mail-clad horsemen
managed to cut their way through to safety. One of these, a force of
some two hundred, headed by Earl Warenne himself, and his
brothers-in-law, Guy of Lusignan and William of Valence, secured their
retreat to the spacious castle of Pevensey, of which Warenne was
constable, and from which the possibility of continuing their flight by
sea remained open. Of greater military consequence was the successful
escape of the lords of the Welsh march, whose followers were next day
the only section of the royalist army which was still a fighting force.
This was the only immediate limitation to the fulness of Montfort's
victory. After seven weary years, the judgment of battle secured the
triumph of the "good cause," which had so long been delayed by the
weakness of his confederates and the treachery of his enemies. Not the
barons of 1258, but Simon and his personal following _were_ the real
conquerors at Lewes.

CHAPTER VI.

THE RULE OF MONTFORT AND THE ROYALIST RESTORATION.

On the day after the battle, Henry III. accepted the terms imposed upon
him by Montfort in a treaty called the "Mise of Lewes," by which he
promised to uphold the Great Charter, the Charter of the Forests, and
the Provisions of Oxford. A body of arbitrators was constituted, in
which the Bishop of London was the only Englishman, but which included
Montfort's friend, Archbishop Eudes Rigaud of Rouen; the new papal
legate, Guy Foulquois, cardinal-bishop of Sabina; and Peter the
chamberlain, Louis IX.'s most trusted counsellor, with the Duke of
Burgundy or Charles of Anjou, to act as umpire. These ar
