 Aimery led an effective sally that split the attacking troops and forced them to retreat, lifting the siege.The next year (1214), Aimery was one of those who intervened with Pope Innocent and forced him to order Simon to do homage to King James I of Aragon for his lands in southern France.When Simon hesitated to obey, Aimery prepared for war, but the intervention of Cardinal Peter of Benevento, the Papal legate for Provence, prevented open hostilities.
