capture of Bedford, Hubert undertook the recovery of Poitou and the
defence of Gascony. Henry's younger brother Richard, a youth of sixteen,
was appointed Earl of Cornwall and Count of Poitou, dubbed knight by his
brother, and put in nominal command of the expedition despatched to
Gascony in March, 1225. His experienced uncle, William Longsword, Earl
of Salisbury, and Philip of Aubigny, were sent with him as his chief
counsellors. Received with open arms by Bordeaux, he boasted on May 2
that he had conquered all Gascony, save La Réole, and had received the
allegiance of every Gascon noble, except Elie Rudel, the lord of
Bergerac. The siege of La Réole, the only serious military operation of
the campaign, occupied Richard all the summer and autumn, and it was not
until November 13 that the burgesses opened their gates. As soon as the
French had retired, the lord of Bergerac, "after the fashion of the
Poitevins," renounced Louis and professed himself the liegeman of Earl
Richard. Then the worst trouble was that Savary de Mauléon's ships
commanded the Bay of Biscay, and rendered communication between Bordeaux
and England very difficult.[1] Once more the men of the Cinque Ports
came to the king's aid, and there was severe fighting at sea, involving
much plunder of merchant vessels and dislocation of trade.

The English sought to supplement their military successes by diplomacy.
Richard of Cornwall made an alliance with the counts of Auvergne, and
the home administration negotiated with all possible enemies of the
French King. A proposal to affiance Henry's sister, Isabella, to Henry,
King of the Romans, the infant son of Frederick II., led to no results,
for the Archbishop of Cologne, the chief upholder of the scheme in
Germany, was murdered, and the young king found a bride in Austria. Yet
