The lovely weather which attended the fleet brought it, in spite of some delays, before the fortress of Zara on Saint Martin's eve (November 10). No stronghold in the dominions of Venice could compare with this for strength, and a girdle of lofty watch-towers secured it against surprise. It was garrisoned by Hungarian soldiers under fine discipline, and the Zaratines were a brave people. Seventeen years had elapsed since they had expelled the last Venetian Podestà from their territory, and they had full faith in their ability to repulse an enemy.
But the Zaratines had not counted on such a force as now besieged them, and on the second day offers of surrender were made to Dandolo, on condition that the lives of the people were spared. The Doge left the emissaries in order to consult with the barons, and returning to his pavilion found the Zaratines gone, and in their stead the Pope's envoy, Abbot Guy of Vaux-Cernay, who advanced with an open letter in his hand, exclaiming, "Sir, I prohibit you, in the name of the Apostle, from attacking this city; for it belongs to Christians, and you are a pilgrim!"
Dandolo was furious, and none the less so when he learned that Abbot Guy had persuaded the Zaratines not to surrender to the Venetians. But a council was called, and the barons agreed with the Doge to resume the siege at once. The abbot had led the Zaratines to believe that under no circumstances would their lives be spared, and the second siege was fiercely contested. On the sixth day the city fell, and was given up to pillage. Fierce quarrels ensued between the French and the Venetians over the division of the spoil; and this uproar was scarcely calmed before an emissary from his Holiness arrived, calling the Crusaders to account for their present occupation and commanding them to retain no booty.
The French nobles were greatly disturbed, while the old Doge and his councillors were indifferent to the curses or blessings of the Pontiff, who had directed the barons to hold no intercourse with the Venetians, "except by necessity, and then with bitterness of heart." Innocent expected the Crusaders to proceed at once to Constantinople, and suggested that if the Emperor, to whom he had already written, did not supply them generously with provisions, they might, "in the name and for the sake of the Redeemer," seize such things as they needed, wherever they could be had. He concluded by commanding them to proceed at once to Palestine, "turning neither to the right nor to the left." This in no wise affected the Venetians. They were excommunicated; but what of that? They had demanded their pound of flesh from the Crusaders, which was the taking of Zara, to which the barons had agreed; and Dandolo, by his addition to the fleet and the army, at his own cost or that of Venice, had left them little cause of complaint of their bargain, since without him they could not even start for Palestine. Whatever future causes of dissatisfaction might arise against him, thus far it had been purely a business transaction between the Doge and the barons. Of the present condition Gibbon says:—
"The conquest of Zara had scattered the seeds of discord and scandal; the arms of the allies had been stained in their outset with the blood, not of infidels, but of Christians; the King of Hungary and his new subjects were themselves enlisted under the banner of the cross; and the scruples of the devout were magnified by the fear or lassitude of the reluctant pilgrims. The Pope had excommunicated the false Crusaders who had pillaged and massacred their brethren, and only the Marquis Boniface and Simon of Montfort escaped these spiritual thunders,—the one by his absence from the siege, the other by his final departure from the camp."
The soldiers became so turbulent as to give constant anxiety to the barons; and the Zaratines were happy at the enmities among the invaders, and encouraged by the Pope's care for their interests.
The Crusaders sent humble apologies to the Pontiff, so depicting to him the uncontrollable circumstances which had surrounded them, as in a net, that the heart of Innocent was touched, and he sent to Monteferrato his blessing and pardon for himself and the Crusaders.
But Dandolo told the Nuncio that in the affairs of Venice the Pope could scarcely be interested, since his Holiness had no concern in them, and he neither asked nor desired any communication with the Holy See.
Dandolo now displayed his remarkable power as a leader. He proposed to the Crusaders that with the Venetians they should winter at Zara. But they, just when they hoped at once to proceed to Palestine, would hear nothing of such a plan, and insisted on their duty to obey literally the commands of the Pope.
But Dandolo reminded them that in Zara they had spacious barracks and stables; that they were going to a hostile land where no provision had been made for them; that the winter voyage was dangerous, and, in a word, that it would be madness to leave Zara before the spring. There was much angry altercation, but the calm determination of the Doge prevailed. Indeed, without his consent, how could they go? and the army was ordered into winter quarters. Dandolo, Monteferrato, and the barons were all sumptuously lodged; and the Doge set about measures to insure the permanency of his conquest of Zara.
