Frederick, son of Leopold, duke of Austria; Conrad marquis of Moravia; Valeran de Limbourg; and the bishops of Wurtzburg, Bremen, Verdun, Habbastadt, Passau, and Ratisbon.[15] The crusade was preached in all the provinces of Germany, and the letters of the emperor and the pope kindled the zeal of the Christian warriors everywhere; never had an enterprise against the infidels been undertaken under more favourable auspices. As Germany undertook the crusade almost singly, the glory of the German nations seemed as much interested in this war as religion itself. Henry was to command the holy expedition; and the Crusaders, full of confidence and hope, were preparing to follow him to the East. But Henry entertained other views; several nobles of his court, some who penetrated his secret designs, and others who believed they offered him prudent advice, conjured him to remain in the West, and direct the crusade from the bosom of his dominions; and Henry, after a slight resistance, yielded to their prayers, and gave his whole attention to the hastening of the departure of the Crusaders. The emperor of Germany placed himself at the head of forty thousand men and took the route for Italy, where everything was prepared for the conquest of Sicily; the remainder of the Crusaders were divided into two armies, which, proceeding by different roads, were to meet in Syria. The first, commanded by the duke of Saxony and the duke of Brabant, embarked at ports of the German Ocean and the Baltic; the second crossed the Danube, and directed its march towards Constantinople, whence the fleet of the Greek emperor Isaac was to transport it to Ptolemaïs. To this army, commanded by the archbishop of Mayence and Valeran de Limbourg, were joined the Hungarians, who accompanied their queen Margaret, sister to Philip Augustus. The queen of Hungary, after having lost Bela her husband, had made a vow to live only for Christ, and to end her days in the Holy Land.
