Only two weeks after the treaty, Jean de Grailly encouraged an inquiry to determine whether or not he Quercy was English territory.
The mutually acceptable formula resulting was: actum fuit regnantibus Philippo regis Francie, Edwardo rege Anglie, duce Aquitanie.
Between 1280 and 1285 Grailly took part in the tortuous negotiations concerning the inheritance of the County of Bigorre after the death of the five-times married Countess Petronilla.
Nonetheless the question of whether Bigorre was a feudatory of the Duke of Aquitaine or the King of France was to be an issue between the two monarch throughout the fourteenth century.
Jean de Grailly eventually fell short of funds for his activities, since his expenses need approval from the Exchequer before he could receive his salary.
He was removed from office sometime between June 1286 and Spring 1287, when the king and Queen Eleanor of Castile, present in Gascony, set up an inquiry into his actions.
[1] Following the fall of Tripoli, Jean was sent to Europe by king Henry of Cyprus to warn European monarchs about the critical situation in the Levant.
[2] Jean met with Pope Nicholas IV who shared his worries and wrote a letter to European potentates to do something about the Holy Land.
Wounded, he was rescued during one point of siege by his fellow Savoyard Otho de Grandison, once a faithful servant of Edward's as well, and escaped on ship to Cyprus.
