With so much success, de Montfort had received but one check during the year. A temporary coolness had sprung up between him and Arnaut Amalric. The redoubtable Cistercian, having been elected Archbishop of Narbonne, wished to be Duke of that city as well. The title was hereditary in Raymond’s family, but by this time he was no longer worth considering in Languedocian politics; the sole contest for the office was between Arnaut Amalric and de Montfort. Angry at being opposed, Arnaut Amalric went off to join Pedro of Aragon and fought under him through the summer of 1212 against the Moors in Spain. Had the energetic legate remained in Languedoc, de Montfort’s great successes of the year might have been even greater. However, the estrangement between the two leaders of the Albigensian Crusade was only temporary. From de Montfort’s point of view, the serious thing about the Spanish campaign was its complete success and the increased prestige of King Pedro which resulted therefrom. Far to the south, at “Las Navas de Toulosa,” about the time that La Penne d’Agen fell to de Montfort, King Pedro helped to break the last great army of the African Moslems that Spain was ever to see. For the Albigensian Crusade to have its chief opponent known as one of the foremost champions of Christendom in Europe was an ominous thing. All the time the Pope, the mainspring of the enterprise now rapidly outgrowing his original design, had kept clearly in his mind the religious purpose of the Crusade as opposed to its later political development. During the year he had again protected Durand of Huesca, writing letters in behalf of his following of converted heretics turned Catholic missioners to the bishops of France and Italy. By such action Innocent obstinately refused to go over to the extreme party that was for making an end of mildness and mercy even to the repentant sinner. Furthermore, outside Languedoc, in the previous year in the case of a canon of Bar-sur-Aube who feared for his life because of his heretical reputation in his own neighbourhood, he had insisted that the accused be protected from mob violence. The great Pope was a great lawyer and a great gentleman.
