become from the realities of the crusade that he could imagine his strictures would exert any influence. Throughout 1202 to 1204, Innocent was handicapped by poor or delayed information mediated though those who pandered to his wishful thinking. Even after his prohibition on the attack on Zara had been blatantly disregarded, Innocent clung to the hope that the object of the crusade would be achieved in the end.32 Once Peter Capuano and the crusade parted company at Venice, one for Rome, the other for Zara, Innocent’s dilemma was fixed. The only control over the expedition left him was its cancellation.
The prospects for young Alexius improved as the crusaders’ debts rose. Crucially, Boniface of Montferrat was persuaded to back the scheme, perhaps during his absence from the crusade fleet between October and December 1202, confirming that the diversion to Constantinople to some degree represented a revival of Hohenstaufen eastern policy evident in Henry VI’s crusade plan. The Venetians were greatly in favour of the move, officially as it would secure the funding and provisioning of the expedition to Outremer. From their privileged position within Byzantium, the Venetians knew how feeble the Greek naval defences were and how the provinces were splitting away from the centre. Backing a successful coup would enhance Venice’s privileged position in the empire, stealing a march on the Genoese and Pisans, whose links with young Alexius could usefully be severed in the process. The young Alexius’s promised bounty offered full compensation for the Venetian capital expended in building and provisioning the crusade fleet. Armed with a highly dangerous army and equipped with a magnificent fighting fleet, the Venetians saw Alexius’s offer as a unique opportunity. Although there is no reason to suppose the Venetians had planned it, they would have been eccentric not to embrace it.
The crusader high command agreed, effectively settling the crusade’s future course. Alexius was summoned from Philip of Swabia’s court. However, the arguments reflected profound divisions within the army that could not easily be dismissed by the leadership’s
The arguments appeared both simpler and more difficult in the camp at Zara. On news of the proposals and the willingness of the leadership to agree, defections accelerated. Reactions varied. Two separate objections emerged, one of principle, that fighting Christians was wrong; the other more practical, that the crusade should not delay in attacking Egypt. The leadership’s arguments were crafted to refute the former, insisting the diversion was just, and to reassure the latter, by presenting the Greek strategy as supportive and preparatory to the war further east. Not all were convinced. Some simply left, including, damagingly, the cousin of Louis of Blois, Reynald of Montmirail, who went to the Holy Land. Robert of Clari noted the opposition, but seemed more swayed by the stories of Greek atrocities against Alexius and Boniface of Montferrat’s family, and by the religious sanction given by the pliant clergy on the grounds that Alexius, the rightful heir, had been disinherited. Thus the diversion ‘would not be a sin but a righteous deed’ (
The pope bowed to pressure and assurances from the crusade high command of their penitence for the attack on Zara, which they argued was forced on them by necessity.37 However, anxious lest their rights to Zara be undermined, the Venetians remained unrepentant and excommunicated, although Innocent forgave Boniface of Montferrat for suppressing publication of this bull of excommunication in the interests of army unity. The continued excommunication of their carriers reduced the crusaders and the pope to intricate sophistical contortions to allow soldiers of Christ to accept transport from those under the church’s anathema. More generally, the pope had placed himself in an increasingly false position. His refusal in February to condone any further attack ‘on the lands of Christians’, was diluted by his acceptance that a ‘just and necessary cause’ might allow an exception.38 To some observers, Alexius’s offer to submit the Greek church to Roman authority simply followed Innocent’s own stated policy, making his disquiet less easy to understand or even believe. His repeated prohibition of 21 April came as the fleet was leaving Zara for Byzantium. In June, he publicly rejected the justification for the diversion put up by the army’s bishops:
not one of you should rashly flatter himself that he is allowed to occupy or prey upon the land of the Greeks because it might be too little obedient to the Apostolic see and because the emperor of Constantinople usurped the empire… it is not your business to judge their crimes.39
Too little: too late. As the letter was being drafted, the crusade fleet was already edging its way into the Sea of Marmora.
By the time the crusade sailed from Zara in April 1203, their ranks had been further depleted by the departure of Simon of Montfort and the abbot of Vaux. At least this removed a vociferous source of dissent. However, even after leaving Zara, the issue of the crusade’s destination was not finally settled. The fleet left Zara in stages, agreeing to muster at Corfu. The young Alexius only arrived at Zara on 23 April 1203, where he was greeted by Boniface of Montferrat and Doge Dandolo. After a propaganda stop at Durazzo to allow Alexius to receive the public, although hardly unforced, approval of a Greek city, the marquis, doge and pretender caught up with the main army camped on Corfu. There the crusade almost fell apart. Faced by the Greek pretender, a large section of the army, as much as half, Villehardouin remembered, balked at the final commitment to restore him. Most of the ideological dissidents may have already left at Zara, but on Corfu many still worried about the propriety of the diversion as well as the practical commitment to the Holy Land. Only strenuous argument, earnest promises, histrionic pleading and emotional blackmail by the small coterie of the high command preserved what was left of the expedition intact. Among the most committed to the Constantinople venture were at least three of the deputation who had negotiated the 1201 treaty of Venice, as well as the count of Flanders and the Hohenstaufen faction, including Marquis Boniface and the bishop of Halberstadt. Once again, money, the control of the paid troops and the support of the Venetians probably swung the day. Even so, Alexius had publicly to swear to abide by the terms of an agreement, which now specified that, after Michaelmas 1203, when the Venetian treaty expired, the leaders were obliged to provide any member of the army with ships to take them to Palestine. While there is no evidence that the leaders dissembled in their acquiescence to this – in August 1203 Hugh of St Pol was still envisaging an attack on Egypt in the spring of 1204–such a bargain, after all the contractual problems the expedition had already experienced, reveals a surprising degree of trust and optimism.40
This optimism was immediately challenged as both the local citizens of the port of Corfu and the Greek ecclesiastical hierarchy made their hostility to Alexius and his western alliance very plain.41 As the fleet pulled away from Corfu on 24 May 1203, its prospects looked far from certain. Since Venice the previous summer, the expedition had lost much of its fighting force, some as casualties, more to disease, but most to desertion, an army now, it was observed not entirely speciously, ‘as insignificant as it was underrated’.42 The pope, from whom the crusaders derived their summons and their privileges, had forbidden them to take the path they were pursuing. Half of ‘the Christian army’,43 the Venetians, were actually excommunicate. Their candidate for the throne, Alexius, was an untested young man of breeding but no experience or proven popularity. Past western involvement in Byzantine dynastic feuding had been less than happy. Over a century of assault from Norman Sicily had failed to secure any permanent territorial gains at Byzantine expense. Constantinople had never been captured by a foreign enemy since its foundation 900 years earlier. Success seemed to rest on believing Alexius’s own questionable estimation of his likely Greek support. This hardly smacked of some deep-seated, long-planned plot to subvert the crusade. As it was, and had been since Venice, expectations were to be repeatedly undone by events.
