The peace established between Frederick and the Saracen rulers was not faithfully observed by the latter, some of whom did not consider themselves as bound by its stipulations. The sufferings endured by the Christians of Palestine accordingly called their brethren in Europe once more to arms. A council, held under the auspices of the pope at Spoleto, decreed that fresh levies should be sent into Asia so soon as the truce with Khamel, the sultan of Damascus, should have expired. Many of the English nobility, inflamed by the love of warlike fame, took the cross, and prepared to follow the standard of the Earl of Chester, and of Richard, earl of Cornwall, brother to King Henry the Third. In this pious movement the lords of England were anticipated by those of France, who, in the year 1239, landed in Syria, and prepared to measure lances with the Moslems. News of these warlike proceedings having reached the nephew of Saladin, he forthwith drove the Christians out of Jerusalem, and demolished the Tower of David,--a monument which till that time had been regarded as sacred by both parties. The combats which followed, although fought with great bravery on the side of the invaders, terminated generally in favour of the Saracens; and the French accordingly, after losing a great number of their best warriors, were glad to have recourse to terms of peace. The Templars entered into treaty with the Emir of Karac, while the Hospitallers, actuated by jealousy or revenge, preferred the friendship of the Sultan of Egypt. The following year Richard, the earl of Cornwall, arrived with his levy, hoping to find his allies in possession of all the towns which had been ceded to the Emperor of Germany, and enjoying security in the exercise of their religious rites. His surprise was therefore very great, when he discovered that the principal leaders of the French had already fled from the plains of Syria; that the knights of the two great orders had sought refuge in negotiation; and, finally, that the conquests of the former Crusaders were once more limited to a few fortresses and a strip of territory on the coast. He marched in the first instance to Jaffa, with the view of concentrating the scattered forces of Europe; but receiving notice, as soon as he arrived, that the Sultan of Egypt, who was then at war with his brother of Damascus, was desirous to cultivate friendly relations, he lent a ready ear to the terms proposed. The Mussulman consented to relinquish Jerusalem, Beritus, Nazareth, Bethlehem, Mount Tabor, and a large portion of the Holy Land, provided the English earl would withdraw his troops and preserve a strict neutrality.
