In April 1398, and again in March 1399, Boniface IX ordered to be preached throughout Christendom a crusade for the defence of Constantinople.[589] His appeals fell on deaf ears. Wenceslaus was approaching the end of his power in the empire, Richard of England was fighting for his throne, Florence was in a struggle with the Visconti, the Duke of Burgundy and the Duke of Orleans were disputing the regency in France. Only Venice and Genoa were vitally interested in the fate of Constantinople.
Because Genoa had put itself under the guardianship of the Duke of Orleans, brother of Charles VI of France, and son-in-law of Duke Giovanni Visconti of Milan, the interests of her Pera colony demanded some attention from the powerful Valois and Visconti families. This made possible the sole response to the appeals of Manuel and the Pope, the expedition of Marshal Boucicaut.
In the summer of 1399, a force of ten thousand Osmanlis, after coming into more or less open conflict with the Genoese of Galata, attempted to enter Constantinople. The defenders were few; for the inhabitants, as at the time of the final siege in 1453, were more likely to be found in the bazaars than on the city walls. They had little desire to prolong a condition which was paralysing their business activities. Clavijo, who visited Constantinople four years later, was informed that the attack failed only because of the lack of skill and energy shown by the Osmanlis.[590] Until they had cannon to help them, the Osmanlis never displayed fighting ability in an assault upon fortifications. At this critical moment, aid arrived from Europe.
Boucicaut was the only one of the prisoners of Nicopolis that accepted the challenge of Bayezid. He did not forget the biting words of the audience at Brusa at the time of their release. On June 26, 1399, with four ships and two armed galleys, he set sail from Aiguesmortes. His force of twelve hundred chevaliers and foot-soldiers had much more cohesion and experience than the volunteers who gathered round Jean de Nevers at Dijon three years before. He was joined at Tenedos by several Genoese and Venetian galleys. After a victory in the Dardanelles over seventeen Ottoman galleys, the first recorded naval combat of the Osmanlis, Boucicaut reached Constantinople ‘just in time to save the city’. He was received with great joy by Manuel, and given the rank of Grand Constable.[591]
For several weeks, Boucicaut and his followers spread terror among the Osmanlis in the Gulf of Nicomedia and the Bosphorus. The Ottoman sailors, no match for the Provençals and Italians, took to cover. An assault on Nicomedia failed, but the fearless marshal made several raids into the interior,[592] and against the Ottoman settlements on the shores of the Marmora and gulfs of Nicomedia and Mudania. His one notable success was against Riva, near the Black Sea entrance of the Bosphorus, on the Asiatic shore.[593] After the castle had been stormed, and the garrison put to the sword, Boucicaut attained the objective of his raid. In the mouth of the river Riva, from which the town takes its name, were hidden the Ottoman galleys and smaller vessels, which had taken refuge there when Boucicaut first appeared in the Golden Horn. All the Ottoman shipping was destroyed by fire.
In order to remove the danger to which Constantinople was subjected by the presence of John Palaeologos, son of Andronicus, at Silivria, constantly intriguing with the Osmanlis, Boucicaut urged Manuel to become reconciled with his nephew. He went, himself—it was less than a day’s sail—to fetch John to Constantinople.[594]
This intervention of Boucicaut in the quarrels of the Palaeologi was more helpful than his military aid. The expeditions in the neighbourhood accomplished little against Bayezid. The chronicler of Boucicaut would have been astonished had he known that Bayezid considered the exploits of Boucicaut’s chevaliers and sailors of too little importance to notice. Bayezid cared only that the Italian republics did not come out openly against him, and lend to the crusaders the powerful and decisive aid which they could have given. The enterprise of Boucicaut demonstrated, however, the impotence of the Osmanlis on sea, and how easily a united effort of Christendom, or of Venice and Genoa alone, could have limited the activities of Bayezid to either Europe or Asia.
When John had been installed as co-emperor, Boucicaut pointed out to Manuel that his force was exhausted, and that he would have to return to France to find recruits. According to some authorities, this action was due to the inability or unwillingness of Manuel to pay the adventurers of Boucicaut for their services in his behalf.[595] Men of their kidney were not fighting for fun or for a cause, and there was no booty to be had from Ottoman sailors and fishermen. Before he left Constantinople, Boucicaut secured the consent of Venice, Genoa, and the chevaliers of Rhodes to his suggestion that Manuel do homage to Charles VI for his empire. This honour the advisers of the French monarch refused to accept. They did not want the king of France bound by the obligation of protecting a vassal whose position was so precarious.
Boucicaut did not return. His restless energy found outlet later in Cyprus, where, as French governor of Genoa, he forced the Cypriotes to raise the siege of Famagusta,[596] and in pillaging the Syrian ports, where his adventurers did far more damage to the Italian merchants than to the Saracens.[597] Even had he returned to Constantinople, and with the highest motives personally, his followers would certainly have done the Constantinopolitans more harm than good, as had been the case with the Catalans, and, when money was not forthcoming, have ended by being in open conflict with those of whom they were posing as the defenders.
