When the knights and barons returned to their homes, bearing a red cross upon their baldrics and their coats of mail,[47] they aroused by their presence the enthusiasm of their vassals and brothers in arms. The nobility of Flanders, after the example of those of Champagne, were anxious to prove their zeal for the recovery of the holy places. Baldwin, who had taken the part of Richard against Philip Augustus, sought beneath the standard of the cross an asylum against the anger of the king of France, and swore, in the church of St. Donatien of Bruges, to go into Asia to combat the Saracens. Mary, countess of Flanders, sister of Thibault, count of Champagne, would not live separated from her husband; and although she was still in the flower of her youth, and was several months advanced in her pregnancy, took an oath to follow the Crusaders beyond the seas, and to quit a home she was doomed never to see again. The example of Baldwin was followed by his two brothers,[48] Eustace and Henry, count of Sarbuck; by Canon de Bethune, whose piety and eloquence were held in high estimation, and by Jacques d’Avesnes, son of him who, under the same name, had made himself so famous in the third crusade. Most of the knights and barons of Flanders and Hainault also took the oath to share the labours and perils of the holy war. The principal leaders first met at Soissons, and afterwards at Compiègne. In their assembly, they gave the command of the expedition to Thibault, count of Champagne. It was decided also that the Crusaders should repair to the East by sea; and, in consequence of this determination, six deputies were sent to Venice,[49] in order to obtain from the republic the vessels required to transport the men and horses.
