The death of Louis restored the confidence of the Saracens; they took the mourning they observed in the camp for discouragement, and flattered themselves with an approaching triumph over their enemies. But their hopes were of very short existence. During the sickness of Philip, now king, Charles of Anjou took the command of the army, and renewed the war with spirit. The soldiers he had brought with him were eager for battle, the diseases became less violent, and the Crusaders, so long confined to their camp, revived at the idea of the perils of war. Several battles were fought round the Lake of Gouletta, which it was necessary for them to possess before they could invest Tunis. The Moors, who only a few days before had threatened the Christians with extermination or slavery, could not stand for a moment the shock of the Christian chivalry; not unfrequently the arbalisters were sufficient to disperse innumerable multitudes. Horrible howlings, the noise of drums and other loud instruments, announced their approach; clouds of dust, pouring down from the neighbouring heights, announced their retreat and concealed their flight. In two rencontres, however, they were caught, and left a great number of dead on the field. Another time their camp was seized and plundered. The sovereign of Tunis could not depend upon his army for the defence of his states, and he himself gave no example of bravery or conduct to his soldiers. He remained constantly in subterranean grottos, to escape at once from the burning rays of the sun and the perils of the fight. Pressed by his fears, he saw no safety but in peace, and resolved to purchase it, if at the expense of all his treasures. His ambassadors came to the camp several times, charged with proposals, and were directed particularly to endeavour to seduce the king of Sicily. The Tunisian monarch was cunning and fortunate in this idea; venality was the weak side of Charles, and the other Crusaders were not immaculate in that respect. After much debating in the Christian council, a truce for ten years was signed, on the 31st of October, between the leaders of the crusade and the king of Tunis. All prisoners were to be restored on both sides, and all the Christians previously in chains were to be set at liberty. The sovereign of Tunis engaged not to require of the Franks any of the duties imposed in his kingdom upon foreign commerce. The treaty granted all Christians the faculty of residing in the states of Tunis, with permission to build churches, and even preach their faith. The Mussulman prince was to pay an annual tribute of forty thousand golden crowns to the king of Sicily, and two hundred and ten thousand ounces of gold for the expenses of the war to the leaders of the Christian army.
