In 1263 Simon
returned from exile in France. He found England in
crisis and the influential Welsh leader,
Llewelyn, expanding his power and influence.
He gathered around him a
small but loyal force of rebellious
barons, looking to the west for support and seeking
alliance with Llewelyn.
He marched towards
London where the Queen fled to Windsor amid jeers and insults from the
Londoners and from there made her way to France.
King Henry shut himself in the tower; he was in
a weak position and agreed once
more to the terms of the Provisions of Oxford and a truce.
He twice broke this truce, but de
Montfort sought legal arbitration from the King
of France. He ruled in favour of absolute
monarchy, in favour of Henry.
The way was clear for the Second Baron's War.
While earl Simon was a
first class general and warrior he had not passed these qualities on to
his sons, Henry and Simon. His campaign leading up to
Lewes was hampered by his sons' setbacks under
his sons. The tone was set when earl Simon
marched to Northampton to relieve Simon the younger,
only to find he had already been captured.
Passing through London earl Simon
seized and held the strategic
point of Rochester, Kent, possibly to forestall
a French invasion force sailing up the Thames.
If this was his aim then he failed because he was unable to neutralise the
castle and its garrison.
For once Henry stole a march on de Montfort, coming swiftly up on him
having made a five day forced march covering over 30 miles
a day. This was an
impressive feat but it would have left the route scattered with
lame and blown horses and
with stragglers who were unable or unwilling to keep
up. Desertion,
too, would have diminished Henry's army. Earl Simon was warned of
the King's approach by his scouts and spies
Earl Simon set off toward the south coast and Henry had to follow through
countryside that had already been
ruthlessly plundered or burned.
Henry's weary troops finally caught up with
Earl Simon at Lewes. With his army hungry,
thirsty, foot-sore and exhausted The King dispersed his army through the
town. The Prince garrisoned Lewes Castle
with his cavalry and the King took his followers
into quarters at a local priory.
