Sealed contracts were exchanged with more weeping and genuflexions, the parties to the contract on either side swearing on the bodies of the saints to well and loyally keep their bond. It was secretly agreed that Babylonia (Old Cairo) should be the objective of the expedition. Publicly it was given out that it was bound for beyond the sea. On the Feast of St John, 1202, the Frankish host was to assemble at San Nicolo on the Lido, and the vessels were to be ready. Every detail was specified; the amount of bread and wine per man, and corn per horse. A court of arbitration was formed to settle matters of dispute that might arise. But selfish and worldly motives swayed the actions of too many among the warriors of the cross and whole armies were foresworn. A rich and powerful detachment set sail from Bruges after swearing on the gospels to join at Venice, but engaged transports at Marseilles and Genoa.

Walter of Brienne,[18] with many another great knight, went off to Apulia to subdue the inheritance of his wife and promised to meet the army at Venice. “But adventures befall as it pleaseth God,” and at the trysting-place they were found wanting. Many others, including the Bishop of Autun, broke their oaths.

Great was the consternation of the leaders of the crusade. The Venetians had honourably, indeed generously, done their part. Never had such a fleet been beheld by Christian men. But the crusaders were too few to fill it or to meet the payment due. The barons spared neither entreaties to their erring companions nor their own possessions and credit. Time went on: the day for meeting their obligations was past; the Venetians demanded payment; 30,000 marks were still wanting, perchance to the secret satisfaction of the Republic, for the Venetians had no keen desire to dislocate their remunerative trade with the East. The Sultan of Egypt was their good friend. Commercial privileges had been granted them while the crusaders were gathering at Venice. Two envoys, Marino Dandolo and Dom. Michieli[19] set sail for Egypt, and in May 1202 had concluded a secret treaty between the Republic and the Caliph, by which in return for increased and substantial commercial privileges the Venetians implicitly agreed to divert the fleet from any attack on Egypt.

The Doge was not slow to make the most of the crusaders’ hard case. For the fifth time Zara had revolted and was held for the King of Hungary. The Frankish leaders were eating their hearts out at the delay; inaction was demoralising their forces. The Doge offered a compromise. The contract had been broken, and legally the amount paid was forfeited, but if the barons would help the Venetians to subdue Zara on the way, the Armata might sail and payment of the balance of money be deferred. The papal legate, Peter of Capua, indignantly declaimed against the bargain, but the barons were in a cleft stick. They could do no other than accept, and the chance of winning from the spoils of Zara enough to pay the balance of their debt was a potent factor in their decision.

All was now ready; the people were assembled in St Mark’s on Sunday, the barons being present, and says Villehardouin ere mult gran feste (there was a very great festival). “Before Mass began the Doge ascended the pulpit and said: ‘Sirs, ye are companions of the best nation in the world for the highest emprise that ever man attempted. I am old and feeble and have need of repose, nor am I whole in body; but I perceive that none can guide nor command you so well as I who am your lord. If ye will grant that I take the sign of the cross and watch over you and direct you, and that my son remain in my stead to guard the land then will I go to live or die with you and the pilgrims.’ When the people heard him they all cried out, ‘We beseech you in God’s name that ye do even as ye say.’ Then great pity melted the hearts of the people of the city and of the pilgrims, and many tears were shed for this valiant man who had so much cause to remain at home, being old, and though his eyes were beautiful he saw not, because he had lost his sight through a wound. But he was of exceeding great courage. He left the pulpit and fell on his knees before the altar, and the cross was sewn on the front of a great silken biretta that it might be seen of all. Then the Venetians began to put on the cross in great numbers, for up to that day few were they who joined.”

At length on the octave of the Feast of the Holy Incarnation of Jesus Christ the host took ship and set forth. Never did so great a fleet sail from any port. “Ah! dear God,” exclaimed Jeffrey, “how many a good steed was there, and great ships charged with arms and gallant knights and squires and banners so fair.”

It was indeed a gorgeous and thrilling spectacle. Three chief Venetian galleys, the Peregrina, the Paradiso and the Aquila towered above the rest of the fleet. The vessels were one mass of glittering steel and magnificently coloured banners, that of St Mark, a golden lion on crimson ground, waved proudly in the wind. The air trembled at the blast of trumpets. In swelling chorus the host burst forth into the Veni Creator Spiritus, and the mighty fleet turned its prows—for Zara.

On the way a punitive call was made at Trieste, which agreed to pay tribute to Venice. Another call was made at Omago and an oath of allegiance exacted. Zara was reached on St Martin’s Eve, the 10th of November. The stronghold so impressed the Marshal of Champagne that he exclaims: “How shall such a city be taken except God be with us!” On the 18th, after a stubborn fight the city yielded, pillage followed and half the booty went to each ally. The Pope was scandalised. He had tried to tamper with the French: he now demanded the restitution of the pillage of a city that belonged to a Christian king and crusader. The barons excused themselves as best they might; the Venetians boldly told the papal nuncio that the Holy See had no concern with the affairs of the Republic.

The season was now far advanced, and the fleet wintered at Zara. The chief of the Crusaders, Boniface, Marquis of Montferrat, who had stayed at Venice, took up his command after the capture. The problem of the fate of the expedition faced the allies. Already a bloody fray had embittered the feeling between Venetian and Frank. Boniface, too, was tempted by his own ambition. He claimed the kingdom of Salonika, and hoped to subdue it with the help of the Armata.
