The army under these leaders landed at Durazzo and passed through Epirus to Adrianople. Although Alexius had communicated with Bohemond, promising him assistance, the Greek troops harassed the advancing forces, and various engagements took place, with considerable loss on both sides; Bohemond then, at the invitation of the emperor, visited Constantinople, leaving his army behind under Tancred. Influenced by large gifts of money and lands, Bohemond did homage to the emperor, and became one of his firmest allies. Impressed with a sense of the humiliation of a concession which had been bought with gold, Tancred determined not to submit to similar demands. On receiving the news the young knight immediately marched his army towards Constantinople, and, crossing the Hellespont--without giving any notice of his intention--joined the forces of Godfrey at Chalcedon. Alexius made many efforts to bring back Tancred to Constantinople, and to induce him to do homage, but without success; and the attention of the emperor was presently drawn in another direction, by the arrival of Raymond of St. Gilles, Count of Toulouse, with an army of Crusaders from Languedoc. Raymond, who is represented as being revengeful and avaricious, but possessing some moral firmness, in conjunction with pride, refused to pay his allegiance to the emperor. The troops of the Count of Toulouse were at a considerable distance from the army of his friends, and Alexius did not hesitate to order a night attack to be made from the city upon the French camp. The Languedocians, however, repulsed their assailants with great loss, and further negotiations, which afterwards took place, only resulted in a second refusal on the part of Raymond to pay the required homage. He, however, consented to take a vow that he would make no attempt against the life or honour of the emperor. Alexius then changed his conduct, and invited the count to the palace, where the luxury and magnificence which surrounded him produced its effect, and Raymond remained for some time amidst the pleasures of the court. Bohemond and Godfrey, however, had already marched from Chalcedon towards Nicæa, the capital of the Turkish kingdom of Roum. On receiving the news of their departure, the Count of Toulouse quitted Constantinople and hastened to follow the main body of the army. Another army, forming the last division of the first Crusade, soon afterwards appeared before Constantinople. Robert of Normandy had at length torn himself away from the pleasures of Italy, and had brought with him a well-appointed army, though fewer in numbers than those which had preceded him. Robert took the oath of allegiance, satisfied with the assurance that the other leaders had already done so, and his army having received supplies from the emperor, passed the Hellespont, and marched towards Nicæa, in the path of their companions.
