their attack and the King took the opportunity to escape to Bordeaux. Simon de Montfort, who fought a successful rearguard action during the withdrawal, was furious with the King's incompetence and told Henry that he should be locked up like the 10th-century Carolingian king Charles the Simple. The Poitou rebellion collapsed and Henry entered into a fresh five-year truce. His campaign had been a disastrous failure and had cost over £80,000. In the aftermath of the revolt, French power extended throughout Poitou, threatening the interests of the Lusignan family. In 1247 Henry encouraged his relatives to travel to England, where they were rewarded with large estates, largely at the expense of the English barons. More Poitevins followed, until around 100 had settled in England, around two-thirds of them being granted substantial incomes worth £66 or more by Henry. Henry encouraged some to help him on the continent; others acted as mercenaries and diplomatic agents, or fought on Henry's behalf in European campaigns. Many were given estates along the contested Welsh Marches, or in Ireland, where they protected the frontiers. For Henry, the community was an important symbol of his hopes to one day reconquer Poitou and the rest of his French lands, and many of the Lusignans became close friends with his son Edward. The presence of Henry's extended family in England proved controversial. Concerns were raised by contemporary chroniclers – especially in works of Roger de Wendover and Matthew Paris – about the number of foreigners in England and historian Martin Aurell notes the xenophobic overtones of their commentary. The term "Poitevins" became loosely applied to this grouping, although many came from Anjou and other parts of France, and by the 1250s there was a fierce rivalry between the relatively well established Savoyards and the newly arrived Poitevins. The Lusignans began to break the law with impunity, pursuing personal grievances against other barons and the Savoyards, and Henry took little or no action to restrain them. By 1258, the general dislike of the Poitevins had turned into hatred, with Simon de Montfort one of their strongest critics. Scotland, Wales and Ireland Henry's position in Wales was strengthened during the first two decades of his personal rule. Following the death of Llywelyn the Great in 1240, Henry's power in Wales expanded. Three military campaigns were carried out in the 1240s, new castles were constructed and the royal lands in the
