At the end of the battle the castle
of Lewes was in Royalist hands as was the priory.
The town itself was in the hands of the rebels,
much of it in flames. Simon de Montfort did not
have sufficient men to turn this stand-off into
a decisive victory so earl Simon turned his
attention on the priory.
Prince Edward, hawkish as
ever, wanted to rally as much cavalry as he
could and ride out to take the fight to
the rebels. Lewes
was a Royalist town and enemies could soon rally to their King and he
would be defeated. Simon knew that he had to
finish what he had reluctantly started,
and quickly. There was no question of
settling down for a prolonged siege.
He
sent envoys
to the priory, with threats
to execute his prisoners. The Royalists
were unmoved; they had important rebel prisoners,
too. More constructive negotiations went
on into the night and concluded the next morning. The
settlement agreed was for the King to respect
and uphold the Provisions of Oxford and all
prisoners were to be released on both sides. This latter provision
sowed the seed for Earl Simon's eventual defeat: the released Royalists
formed a solid cadre of support for the King in the Welsh Marches.
Henry III
became de Montfort’s puppet ruler. While
technically Henry was still King,
Simon de Montfort became, in all important
respects, a Lord Protector of England as if the
King had been a minor. He was to keep the King at his side always,
providing Simon’s rulings with the
legitimacy of the Royal Seal. Earl Simon was now riding
a tiger; however he tried to get off he was likely to meet teeth and
claws.
As part of the settlement Prince Edward
also became
his uncle's prisoner. Richard
of Cornwall fled the field and took refuge in a windmill.
Many high-ranking escaped to France;
Richard was probably among them.
This was a
significant victory for the rebels but it did not produce stability. The
war was still very much there to be won.
