The death of Suleyman and the accession of his brother Musa in 1410 sealed the fate of the Marquess. Early in the spring a very large Turkish army appeared before the old castle. Boudonitza was strong, and its Marquess a resolute man, so that for a long time the siege was in vain. “Giacomo,” says the Venetian document composed by his son, “preferred, like the high-minded and true Christian that he was, to die rather than surrender the place.” But there was treachery within the castle walls; betrayed by one of his servants, the Marquess fell, like another Leonidas, bravely defending the mediæval Thermopylæ against the new Persian invasion. Even then, his sons, “following in their father’s footsteps,” held the castle some time longer in the hope that Venice would remember her distant children in their distress. The Senate did, indeed, order the Captain of the Gulf to make inquiries whether Boudonitza still resisted and in that case to send succour to its gallant defenders—the cautious Government added—“with as little expense as possible.” But before the watchmen on the keep could descry the Captain sailing up the Atalante channel, all was over; both food and ammunition had given out and the Zorzi were constrained to surrender, on condition that their lives and property were spared. The Turks broke their promises, deprived their prisoners of their goods, expelled them from the home of their ancestors, and dragged young Nicolò to the Sultan’s Court at Adrianople[364]. Considerable confusion prevails in this last act of the history of Boudonitza, owing to the fact that the two leading personages, the brother and eldest son of the late Marquess, bore the same name of Nicolò. Hopf has accordingly adopted two different versions in his three accounts of these events. On a review of the documentary evidence, it would seem that the brother, the Baron of Karystos, was not at Boudonitza during the siege, and that, on the capture of his nephew, he proclaimed himself Marquess. Venice recognised his title, and instructed her envoy to Musa to include him in her treaty with the Sultan and to procure at the same time the release of the late Marquess’s son. Accordingly, in the peace of 1411, Musa promised, for love of Venice and seeing that he passed as a Venetian, to harass him no more, on condition that he paid the tribute established. Not only so, but the Marquess’s ships and merchandise were allowed to enter the Turkish dominions on payment of a fixed duty[365]. Thus temporarily restored, the Marquisate remained in the possession of the uncle, from whom the nephew, even after his release, either could not, or cared not to claim it. He withdrew to Venice, and, many years later, received as the reward of his father’s heroic defence of Boudonitza, the post of _châtelain_ of Pteleon, near the mouth of the Gulf of Volo, the last Venetian outpost on the mainland of North-Eastern Greece—a position which he held for eight years[366].
