Henry had no further opportunities to reconquer his possessions in France after the collapse of his military campaign at the [[Battle of Taillebourg]].<ref name=ODNB/> Henry's resources were quite inadequate in comparison to those of the French Crown, and by the end of the 1240s it was clear that King Louis had become the preeminent power across France.<ref>{{Harvnb|Aurell|2003|pp=30–31}}; {{Harvnb|Hallam|Everard|2001|p=275}}</ref> Henry instead adopted what historian [[Michael Clanchy]] has described as a "European strategy", attempting to regain his lands in France through diplomacy rather than force, building alliances with other states prepared to put military pressure on the French King.<ref>{{Harvnb|Weiler|2012|p=4}}; {{Harvnb|Clanchy|1998|p=220}}</ref> In particular, Henry cultivated [[Frederick II, Holy Roman Emperor|Frederick II]], hoping he would turn against Louis or allow his nobility to join Henry's campaigns.<ref>{{Harvnb|Weiler|2012|pp=104–107}}</ref> In the process, Henry's attention became increasingly focused on European politics and events rather than domestic affairs.<ref>{{Harvnb|Weiler|2012|p=4}}</ref>

Crusading was a popular cause in the 13th century, and in 1248 Louis joined the ill-fated [[Seventh Crusade]], having first made a fresh truce with England and received assurances from the Pope that he would protect his lands against any attack by Henry.<ref>{{Harvnb|Hallam|Everard|2001|p=278}}; {{Harvnb|Ridgeway|2004}}</ref> Henry might have joined this crusade himself, but the rivalry between the two kings made this impossible and, after Louis's defeat at the [[Battle of Mansurah (1250)|Battle of Al Mansurah]] in 1250, Henry instead announced that he would be undertaking his own crusade to the Levant.<ref>{{Harvnb|Maier|2003|p=63}}; {{Harvnb|Weiler|2012|p=140}}; {{Harvnb|Ridgeway|2004}}</ref>{{Efn|Some accounts suggest that Louis of France prevented Henry from joining the Seventh Crusade, others that Henry himself did not want to join it because of Louis's leadership role.<ref>{{Harvnb|Maier|2003|p=63}}; {{Harvnb|Ridgeway|2004}}</ref>}} He began to make arrangements for passage with friendly rulers around the Levant, imposing efficiency savings on the royal household and arranging for ships and transport: he appeared almost over-eager to take part.<ref>{{Harvnb|Weiler|2012|pp=140–141}}; {{Harvnb|Tyerman|1996|p=123}}; {{Harvnb|Ridgeway|2004}}</ref> Henry's plans reflected his strong religious beliefs, but they also stood to give him additional international credibility when arguing for the return of his possessions in France.<ref>{{Harvnb|Weiler|2012|pp=140–141}}; {{Harvnb|Tyerman|1996|p=123}}</ref>

Henry's crusade never departed, as he was forced to deal with problems in Gascony, where the harsh policies of his lieutenant, Simon de Montfort, had provoked a violent uprising in 1252, which was supported by King [[Alfonso X]] of neighbouring Castile.<ref>{{Harvnb|Carpenter|2004|p=345}}; {{Harvnb|Hallam|Everard|2001|p=342}}; {{Harvnb|Jobson|2012|p=12}}</ref> The English court was split over the problem: Simon and Eleanor argued that the Gascons were to blame for the crisis, while Henry, backed by the Lusignans, blamed Simon's misjudgment.<ref name=ODNB/> Henry and Eleanor quarrelled over the issue and were not reconciled until the following year.<ref name=ODNB/> Forced to intervene personally, Henry carried out an effective, if expensive, campaign with the help of the Lusignans and stabilised the province.<ref>{{Harvnb|Carpenter|2004|p=345}}; {{Harvnb|Hallam|Everard|2001|p=342}}; {{Harvnb|Ridgeway|2004}}</ref> Alfonso signed a treaty of alliance in 1254, and Gascony was given to Henry's son Edward, who married Alfonso's half-sister [[Eleanor of Castile|Eleanor]], delivering a long-lasting peace with Castile.<ref>{{Harvnb|Carpenter|2004|p=345}}; {{Harvnb|Hallam|Everard|2001|pp=342–343}}</ref>

On the way back from Gascony, Henry met with Louis for the first time in an arrangement brokered by their wives, and the two kings became close friends.<ref>{{Harvnb|Carpenter|2005|pp=3, 6}}</ref> The Gascon campaign cost more than £200,000 and used up all the money intended for Henry's crusade, leaving him heavily in debt and reliant on loans from his brother Richard and the Lusignans.<ref>{{Harvnb|Carpenter|1996|p=123}}; {{Harvnb|Jobson|2012|p=12}}; {{Harvnb|Ridgeway|2004}}</ref>
