De Montfort met this unexpected turn of fortune with his wonted activity, but his hour of prosperity was past, and one might almost say, with the Church historians, that he was weighed down by the excommunication launched at him by the implacable Arnaud of Narbonne, whom he had treated harshly in their quarrel over the dukedom--an excommunication which he wholly disregarded, not even intermitting his attendance at mass, though he had looked upon the censures of the Church with such veneration when they were directed against his antagonists. Obliged, after hard fighting, to leave Beaucaire to its fate, he marched in angry mood to Toulouse, which was preparing to recall its old lord. He set fire to the town in several places, but the citizens barricaded the streets, and resisted his troops step by step, till accommodation was made, and he agreed to spare the city for the immense sum of thirty thousand marks; but he destroyed what was left of the fortifications, filled up the ditches, rendered the place as defenceless as possible, and disarmed the inhabitants. Despite his excommunication, he still had the earnest support of the Church. Innocent died July 20, 1216, but his successor, Honorius III., inherited his policy, and a new legate, Cardinal Bertrand of St. John, and St. Paul, was, if possible, more bitter than his predecessors in the determination to suppress the revolt against Rome. The preaching of the crusade had been resumed, and in the beginning of 1217, with fresh reinforcements of Crusaders and a small contingent furnished by Philip Augustus, de Montfort crossed the Rhone, and made rapid progress in subduing the territories left to young Raymond.
