Pedro’s anxiety was natural. The Count of Foix was one of his most important northern vassals. The road running from the north-west over the Puymorens to the pass of the Cerdagne went by way of Pamiers, Foix, and the upper Ariege. The Cerdagne was the one broad and easy inland pass across the Eastern Pyrenees. By the Cerdagne also ran the shortest line of communication between the centre of Pedro’s power in the kingdom of Aragon on the one hand, and his outlying personal domains, i.e., the Roussillon and the lands of his northern vassals, on the other. Obviously, since the chances of an open break with the Crusade must have been ever present with him, he had no mind to see the north-western approach to so important a pass in de Montfort’s hands. The Pope had been pressing the Aragonese to come out strongly for the Crusade. When at last Pedro obeyed he did so with a Spanish thoroughness, accepting de Montfort’s long refused homage for Beziers and Carcassonne, offering to marry his son Jaime, the heir of Aragon, with de Montfort’s daughter, and even handing over the young prince into de Montfort’s power as a sort of hostage. Probably the King, like Count Raymond two years before, thought that the best way of keeping the Crusade within bounds was to go along with it. That it was his real intention to continue playing a double game he presently proved by marrying his sister to the often widowed Count of Toulouse. At Montpellier and Arles the same parties in interest, minus the Court of Foix, were present. For Raymond the conditions offered were hard: razing of his castles, unlimiting billeting rights throughout his lands for crusading soldiers, and, for himself, pilgrimage to the Holy Land “as long as the legates shall wish to prolong his penitence.” King Pedro took the matter calmly, remarking merely that the conditions needed amendment at the hand of the Pope himself. Count Raymond again broke off negotiations, and rallied his vassals to him by publishing far and wide the harsh conditions offered. This time the legates re-excommunicated him. Gradually, in spite of himself he was being forced into a position of open hostility. Innocent sustained Arnaut Amalric and in April confirmed the renewed excommunication of Raymond. Still the latter failed to break completely with the Crusade.
