Both the people and the court were affected by the deepest regret, and that which added to the public anxiety was the circumstance that every one was ignorant of the point to which the expedition was to be directed: the coast of Africa was only vaguely conjectured. The king of Sicily had taken the cross without having the least inclination to embark for Asia; and when the question was discussed in council, he gave it as his opinion that Tunis should be the object of the first attack. The kingdom of Tunis covered the seas with pirates, who infested all the routes to Palestine; it was, besides, the ally of Egypt, and might, if subdued, be made the readiest road to that country. These were the ostensible reasons put forth; the true ones were, that it was of importance to the king of Sicily that the coasts of Africa should be brought under European subjection, and that he did not wish to go too far from Italy. The true reason with St. Louis, and that which, no doubt, determined him, was, that he believed it possible to convert the king of Tunis, and thus bring a vast kingdom under the Christian banners. The Mussulman prince, whose ambassadors had been several times in France, had himself given birth to this idea, by saying, that he asked nothing better than to embrace the religion of Jesus Christ:[29] thus, that which he had said to turn aside an invasion, was precisely the cause of the war being directed against his territories. Louis IX. often repeated that he would consent to pass the whole of his life in a dungeon, without seeing the sun, if, by such a sacrifice, the conversion of the king of Tunis and his nation could be brought about; an expression of ardent proselytism that has been blamed with much bitterness, but which only showed an extreme desire to see Africa delivered from barbarism, and marching with Europe in the progress of intelligence and civilization, which are the great blessings of Christianity. As Louis traversed his kingdom on his way to Aigues-Mortes, where the army of the Crusaders was to embark, he was everywhere hailed by the benedictions of his people, and gratified by hearing their ardent prayers for the success of his arms; the clergy and the faithful, assembled in the churches, prayed for the king and his children, and all that should follow him. They prayed also for foreign princes and nobles who had taken the cross, and promised to go into the East; as if they would, by that means, press them to hasten their departure.
