e et Franciae
se gesserint_, 1152-1328 (1893).

A minor result of Louis' triumph was the well-deserved ruin of Hugh of
Lusignan and Isabella of Angouleme. The proud spirit of Isabella did
not long tolerate her humiliation. She retired to Fontevraud and died
there in 1246. Hugh X. followed her to the tomb in 1248. Their eldest
son, Hugh XI., succeeded him, but the rest of their numerous family
turned for support to the inexhaustible charity of the King of England.
Thus in 1247 a Poitevin invasion of the king's half-brothers and
sisters recalled to his much-tried subjects the Savoyard invasion of
ten years earlier. In that single year three of the king's brothers and
one of his sisters accepted his invitation to make a home in England.
Of these, Guy, lord of Cognac, became proprietor of many estates.
William, called from the Cistercian abbey in which he was born William
of Valence, secured, with the hand of Joan of Munchensi, a claim to the
great inheritance that was soon to be scattered by the extinction of
the male line of the house of Marshal. Aymer of Valence, a very
unclerical churchman, obtained in 1250 his election as bishop of
Winchester, though his youth and the hostility of his chapter delayed
his consecration for ten years. Alice their sister found a husband of
high rank in the young John of Warenne, Earl of Warenne or Surrey,
while a daughter of Hugh XI. married Robert of Ferrars, Earl of Ferrars
or Derby. Others of their kindred flocked to the land of promise. Any
Poitevin was welcome, even if not a member of the house of Lusignan.
Thus the noble adventurer John du Plessis, came over to England,
married the heiress of the Neufbourg Earls of Warwick, and in 1247 was
created Earl of Warwick. The alien invasion took a newer and more
grievous shape.

The expenses of the war were still to be paid; and in 1244 Henry
assembled a council, declaring that, as he had gone to Gascony on the
advice of his barons, they were bound to make him a liberal grant
towards freeing him from the debts which he had incurred beyond sea.
Prelates, earls, and barons each deliberated apart, and a joint
committee, composed of four members of each order, drew up an
uncompromising reply. The king had not observed the charters; previous
grants had been misapplied, and the abeyance of the great offices of
state made justice difficult and good administration impossible. The
committee insisted that a justiciar, a chancellor, and a treasur
