No doubt the Pope, the man of so many disappointments, had set his heart on this as a thing in which for once he must not fail, and watched with a sore and angry heart the unsuccess of all these legitimate efforts. But it was not until one of the legates, a man most trusted and honoured, Pierre de Castelnau, was treacherously killed in the midst of his mission, that Innocent was fully roused. Heretofore he had rained excommunications over all the world, and his curses had come back to him without avail. But on this occasion at least he had a sure weapon in hand. The Pope proclaimed a Crusade against the heretics. He proclaimed throughout Europe that whoever undertook this holy enterprise it should be counted to him as if he had fought for Jerusalem: all the indulgences, blessings, hopes for heaven and exemptions for earth, which had been promised to those who were to deliver the Holy Sepulchre, were equally bestowed on those who went no further than the south of France, one of the richest districts in Christendom, where fair lands and noble castles were to be had for the conquest without risking a stormy voyage or a dangerous climate. The goods of unrepentant heretics were confiscated, and every one was free to help himself as if they had been Turks and infidels. In none of his undertakings was the Pope so hotly in earnest. There is something of the shrillness of a man who has found himself impotent in many undertakings in the passion which Innocent throws into this. "Rise, soldier of Christ!" he cries to the king of France; "up, most Christian prince! The groans of the Church rise to your ears, the blood of the just cries out: up, then, and judge my cause: gird on your sword; think of the unity of the cross and the altar, that unity taught us by Moses, by Peter, by all the fathers. Let not the bark of the Church make shipwreck. Up, for her help! Strike strongly against the heretics, who are more dangerous than the Saracens!" The appeal came to a host of eager ears. Many good and true men were no doubt among the army which gathered upon the gentle hill of Hyères in the blazing midsummer of the year 1209, cross on breast and sword in hand, sworn to exterminate heresy, and bring back the country to the sway of the true religion; but an overwhelming number besides, who were hungry for booty however obtained, and eager to win advancement for themselves, filled up the ranks. Such motives were not absent even from the bosom of Simon de Montfort, their general, otherwise a good man and true. The sovereignty of Toulouse glimmered before him over seas of blood, which was as the blood of the Saracen, no better, though it flowed in the veins of Frenchmen; but the Provençaux could scarcely be called Frenchmen in those early days. They were no more beloved of their northern neighbours than the English were by the Scots, and the expedition against them was as much justified by distinctions of race as was the conflict of Bannockburn.
