Louis formally took the cross on 24 March 1267 at an assembly of his nobles. A second ceremony took place on 5 June 1267 before a papal legate in Notre-Dame de Paris. Louis's son-in-law, King Theobald II of Navarre, who had also taken the cross, was also present. The response was less enthusiastic than to his calling of the Seventh Crusade in 1248, although its unpopularity may have been exaggerated by his chronicler Jean de Joinville, who was personally opposed to the venture. The crusade was set to sail from Aigues-Mortes in early summer 1270 in Genoese and Marseillois shipping. An Aragonese contingent under James I of Aragon sailed from Barcelona in September 1269, but was caught in a storm and badly damaged; most of the survivors returned home, while one squadron under the King's natural sons Pedro Fernández and Fernán Sánchez reached Acre. Too weak to engage Baibars, they soon returned to Aragon as well.
