Meanwhile both parties had proceeded without waiting the event in Rome. In France the crusade had been vigorously preached; Louis Cœur-de-Lion, son of Philip Augustus, had taken the cross with many barons, and great hopes were entertained of the overwhelming force which would put an end to further resistance, when Philip's preparations for the invasion of England caused him to intervene and stop the movement which threatened seriously to interfere with his designs. On the other hand, King Pedro entered into still closer alliance with Raymond and the excommunicated nobles, and received an oath of fidelity from the magistracy of Toulouse. When the papal mandate was received, he made a pretence of obeying it, but continued, nevertheless, his preparations for the war, among which the one which best illustrates the man and the age was his procuring from Innocent the renewal of Urban's bull of 1095, placing his kingdom under the special protection of the Holy See, with the privilege that it should not be subjected to interdict except by the pope himself. A _sirvente_ by an anonymous troubadour shows how anxiously he was expected in Languedoc. He is reproached with his delays, and urged to come to collect his revenues from the Carcassès like a good king, and to suppress the insolence of the French, whom may God confound.[150] The rupture came with a formal declaration of war from Pedro, accepted by de Montfort, though he had but few troops and the hoped-for reinforcements from France were not forthcoming; indeed, a legate sent by Innocent to preach the crusade for the Holy Land had turned in that direction all the effort which Philip would permit to be made. Pedro had left in Toulouse his representatives and had gone to his own dominions to raise forces, with which he recrossed the Pyrenees and was received enthusiastically by all those who had submitted to de Montfort. He advanced to the castle of Muret, within ten miles of Toulouse, where de Montfort had left a slender garrison, and was joined by the Counts of Toulouse, Foix, and Comminges, their united forces amounting to a considerable army, though far from the hundred thousand men represented by the eulogists of de Montfort. Pedro had brought about a thousand horsemen with him; the three counts, stripped of most of their dominions, can scarce have furnished a larger force of cavaliers, and the great mass of their array consisted of the militia of Toulouse, on foot and untrained in arms.[151]
