There was no resistance until Avignon was reached on June 10. There the citizens refused the “French” entry and manned their walls, although they promised not to harass the army in its march if they were left in peace. The place was within the Holy Roman Empire, but Cardinal Romano, the legate, urged Louis to destroy it inasmuch as it had remained ten years excommunicate and impenitent for tolerating Waldensianism, so the King laid siege to it. The incident shows how easy it was to influence Louis and draw him away from the central matter in hand, and also, very significantly, how Waldenses were now attacked as readily as Manicheans. The siege dragged on throughout the summer and into the autumn. Raymond of Toulouse cleverly seized his opportunity to move up and lay waste the country from which the besieging army must draw food and forage. Disease and a plague of flies in the French camp made matters worse. On top of this Pierre Mauclerc, Louis’s second cousin, quarrelled with the King and left the army. Philip Augustus had made this man Count of Brittany by marrying him to the heiress of that fief, and now that she was dead he was out to marry the heiress of Flanders and was angry when Louis thwarted him. So he went off, after serving for forty days, and began strengthening his castles and intriguing with the disaffected Counts of Champagne and of La Marche in Poitou, both of whom were supposed to have an understanding with Raymond. But Louis, although easy to persuade, was not easy to discourage. He stuck to it until, after three months’ siege, Avignon surrendered on September 10. The citizens had been brought very low by the long blockade. They therefore consented to pay ransom, demolish or dismantle their fortifications, and accept from the legate a bishop pledged to suppress heresy. After the long delay at Avignon the army was at last directed against Toulouse. Almost all the Languedocian cities, including Nismes, Narbonne, Carcassonne, Albi, Beziers, Marseilles, Castres, and Puylaurens had already declared for Church and King. But, just as the end seemed in sight, the hardships of the campaign forced Louis to turn homewards, sick with dysentery. At Montpensier, in Auvergne, on November 8, he died. Within a little over three years after Philip Augustus’s death, his fear had been realized: the kingdom he had given his life to build was in the hands of a woman and child.
