The next objective of the Crusade was the strong hill-fortress city of Carcassonne. Thither Raymond Roger Trencavel had gone, leaving Beziers before its investment. The massacre had strengthened his determination to resist, and he had gone so far as to destroy all mills near Carcassonne so as to hinder the provisioning of the Crusaders should the expected siege be prolonged. The “soldiers of Christ” appeared before the place on or about July 24, 1209, having left Beziers the morning of the 22nd, the day after the massacre, and covered the intervening distance of over fifty miles in forty-eight hours, assuming that they went through Narbonne along the line of the Roman road and the modern railway—another good piece of marching. Carcassonne was a much tougher nut to crack than Beziers. The steep escarpements of its hill were crowned by the remarkable circuit of late Roman walls and towers which we see to-day. Only the château, the outer town wall, the gates in the main wall, and a few large towers easily distinguishable from the older work have been added since 1209. The customary first assault to feel out the defence was repulsed with loss, although the defenders also suffered. Another attack carried the slightly fortified suburbs on the lower slopes of the hill crowned by the city proper. This success was followed by a pause of some weeks, during which siege engines of different sorts were constructed. Meanwhile diplomacy was active. King Peter of Aragon intervened in the hope of making peace between the Crusaders and his vassal, Trencavel. He was a picturesque person, a great lover of tournaments and of women, what we should call to-day a sportsman; also a great fighter against the Moslem. In language and culture Aragon was then closer to Languedoc than Languedoc to Northern France. Peter, himself a troubadour and a generous patron of troubadours, held the Roussillon in his own right, and claimed from many of the southern nobles a homage difficult, if not impossible, to reconcile with the homage they owed to the far-off king “of Paris.” Like the other southern leaders, who sooner or later opposed the Crusade, he was no heretic. On the contrary, he delighted to be known as “the Catholic,” and had in person done homage to the Pope for his kingdom, as recently as 1204, and received in return the title of “First Standard Bearer of the Church.” His ferocious legislation against heretics in general has been noted in the last chapter. On the other hand, Spanish religious enthusiasm, in the early Middle Ages, was generally directed far more towards belabouring the infidel than towards discussing doctrine. Politically, King Peter necessarily disliked any extension of North French influence in the south, and could not sit still and see his kinsman and vassal Trencavel destroyed merely because he had not been active enough in putting down heresy. Finally, he was now brother-in-law to Raymond of Toulouse, whose fifth and last wife was his sister.
