Of all Pons's works, with the possible exception of the "planh", only his two crusade songs can be dated with confidence to around 1213. "So qu'om plus vol e plus es voluntos" was written after the battle of Las Navas de Tolosa (16 July 1212) and before the battle of Muret (12 September 1213), since it was dedicated to Peter II of Aragon, who died there. The crusade song "En honor del pair'en cui es", which has the form of a "sirventes", refers to war of the Holy Roman Emperor (probably Otto IV) and the King of England against Philip II and the "King of Apulia" (probably Frederick II). This is probably the War of Bouvines.
