The other two islands shared the fate of Lemnos. In the autumn of 1459, Zaganos, Ismael’s successor in the command of the Turkish fleet, captured both Thasos and Samothrace, cutting to pieces the Catalan garrison placed by Scarampi in the former, and removing Thasians and Samothracians alike to recolonise Constantinople. In the following year the Sultan bestowed these two islands also, together with Ænos, upon Demetrios Palaiologos, who thus became the heir of the Gattilusj in Thrace and the four maritime dependencies[626]. In vain, Pius II urged Rhyndakenos, the former prefect of the Gattilusj, to release Samothrace from its captivity. In vain, he gave Turkish Imbros to Alexander Asan[627].

About the time that Lemnos fell, the learned Leonardo of Chios, who had held the Archiepiscopal see of Lesbos since 1444 and was on very intimate terms with the reigning family, was sent to ask the aid of Christendom for that sole remaining island. The Genoese Government early in 1459 appealed to the Christian Powers and more especially to Charles VII of France, whose viceroy, the Duke of Calabria, was then administering Genoa, reminding them of the recent attack of the Turks upon Lesbos, of the exiguous resources of its lord, and of the impossibility in which the exhausted Genoese now found themselves of supporting him without external assistance, as they had done before, against another and more serious invasion. The fall of Lesbos, it was added, might encourage the Sultan to direct his arms against Italy. Unfortunately this appeal met with no response. Indeed, one of the Christian Powers, England, was at that moment greatly incensed with the Gattilusj, owing to the piracies of Giuliano, a celebrated corsair of that family, whose depredations on the merchants of Bristol had caused the arrest of all the Genoese in the country and the confiscation of their goods. Accordingly, the Genoese Government, which had been glad to make use of him as a cousin, when it seemed convenient, now repudiated him as a Greek and an alien. The proceedings of this illegitimate descendant of Francesco II formed the subject of letters to Henry VI, to the Chancellor and the Privy Seal, to the Archbishops of Canterbury and York, to John Viscount Beaumont, the Great Chamberlain, and Humphry Duke of Buckingham. Indeed, it was owing to Giuliano Gattilusio, that “the office of English affairs” was founded at Genoa[628].

The new lord of Lesbos, as one Christian state after another fell, became more urgent in his requests for help, for he knew that even the payment of tribute would not save him. In 1460 he begged that the former practice might be revived of having a board of four commissioners in Chios, who could send 300 men to the relief of Lesbos, whenever the Sultan was preparing to attack it. It was decided to re-constitute this board, but not to impose any new duty for defraying the expense, and a certain number of men from Camogli on the Riviera di Levante were hired for the defence of Lesbos. Towards the close of 1461, he wrote imploring the Republic not to forget him in his distress. But, although the French had then been expelled from Genoa, and Lodovico de Campo-fregoso, husband of Nicolò’s first-cousin, Ginevra Gattilusio, was once more Doge, all the reply that he received was fair words, a futile assertion that in the season of 1462 the Turk would be occupied by land rather than at sea, and a promise to promote a good understanding between Lesbos and the Chartered Company of Chios, which was apt to forget the common danger in the private quarrels of its members—an allusion to the still outstanding dispute between Nicolò and Paride Longo. Weakened by faction at home, divided by rival interests abroad, the Genoese allowed Lesbos to succumb[629].

Mohammed’s conquest of Serbia, Greece, and Trebizond and his campaign in Wallachia had given Nicolò a brief respite, which he had wisely employed in strengthening the fortifications of his island-capital by deepening the moats and heightening the ramparts. To this may be referred his Latin inscription[630] in the castle, dated 1460. But on September 1, 1462, the long-threatened Turkish fleet hove in sight under the command of Mahmûd Pasha, himself a Greek, while the Sultan at the head of the land forces advanced across the plain of Troy, the sight of which is said to have inspired him with the belief that he was the chosen avenger of the Trojans upon the descendants of their conquerors. Mohammed had no difficulty in finding plausible excuses for his invasion of Lesbos. The island had become a receptacle of Catalan pirates, who issued thence to ravage the Turkish coast and returned thither to divide their prisoners, assigning a goodly proportion to their patron. A reluctance to pay his tribute and a secret understanding with the Italians formed further accusations against him, and Mohammed chose to regard himself as the instrument of the Almighty for the punishment of the Lesbian fratricide.

The great Turkish fleet, variously estimated at 67, 110, 125, 150, and even 200 sail, cast anchor in the old harbour of St George, whither Nicolò’s envoys went to enquire the justification of this attack upon an island, whose lords had paid, ever since the death of Dorino I seven years before, an annual tribute of 7000 gold ducats of Venice. Mahmûd replied, that his master wanted the castle and island of Mytilene—a demand repeated by the Sultan himself, when he crossed over from the mainland, with the addition that he would grant Nicolò a sufficient estate elsewhere. Nicolò replied, that he could not yield, except to force, whereupon Mohammed allowed himself to be persuaded by Mahmûd to return to the opposite coast, lest the Venetian fleet, then at Chios, to which Nicolò had appealed for help, should arrive and shut him up in the island. Thereupon the Greek renegade began the siege of the capital, whose walls contained more than 20,000 non-combatants, men, women and children, and were garrisoned by over 5000 soldiers, including 70 knights of Rhodes and 110 Catalan mercenaries from Chios.

After four days’ skirmishing, which resulted in a number of the Latins being cut off from the city and cut up by the Turks, the besiegers landed six large cannon, whose shot weighed more than 700 lbs. apiece, and planted them in favourable positions for bombarding the city—three at the soap works only a stone’s throw from the walls, one at St Nicholas’, another at St Bonne’s[631] near the place of public execution, and the sixth in the suburbs opposite a barbican tower, defended by a monk and a knight of Rhodes. Protected by a barrier of large stones from the fire of the besieged, the Turkish batteries did great execution. The tower of the Virgin and the adjacent walls were pounded till they were nothing but a mass of ruins; the cannon of St Nicholas’ riddled the tower of the harbour, built long before by a Gallego named Pedro de Laranda, so that no one durst defend it, and it fell on the eighth day into the hands of the Turks, whose red flags floated from its riven battlements. The besiegers then concentrated their efforts on the lower castle, called Melanoudion, and commanded by Luchino Gattilusio, who had helped Nicolò to the throne, and whose neglect caused the loss of this important position. It was proposed by the wiser members of his staff to set fire to the lower castle, as they had already burnt to the water’s edge their ships in the harbour, rather than that it should be taken by the Turks and used as a base for attacking the upper citadel. But Luchino boasted that he could hold the fort, and actually held it for five days, although the Turks once climbed the walls and carried off in triumph an Aragonese flag which had been planted there by the Catalan corsairs. At last a force of 20,000 men carried Melanoudion by storm, drove the defenders “like locusts” into the upper castle, and destroyed all that they found. Terrified and breathless, with his naked sword in his hand, Luchino rushed into the midst of the Italians, who had taken refuge in the upper castle, and his narrative struck them with such terror that they resolved to surrender. According to one account, Luchino and the commander of the city had intentionally made further resistance impossible by betraying to Mahmûd the weak points of the defences, and by then urging Nicolò to yield and to save their heads and property. The panic was increased by one huge mortar, whose heavy projectiles destroyed houses and the women inside and drove the terrified defenders from the walls to take shelter from a similar fate. Heavy sums had to be offered, to induce men to repair the breaches; while many, in their despair, flew to drink, and broke into the vast stores of wine and provisions, which, if the garrison had been properly led, would have enabled Mytilene to resist a whole year’s siege. But, though well provided with food and engines of war, the place lacked a brave and experienced soldier, who would have inspired the garrison with enthusiasm. Another council was held, and two envoys were sent to inform Mahmûd, that the inhabitants were ready to become his master’s vassals, if their heads and remaining property were guaranteed. The Turkish commander drew up a memorandum of the terms in writing, and swore by his girded sword and his sovereign’s head that no harm should befall them. The Sultan, on hearing the news, re-crossed to Lesbos, and a janissary was ordered to conduct Nicolò to his presence. Thither the last Latin lord of Lesbos proceeded with two horsemen, kissed the feet of his new master and tearfully handed to Mohammed the keys of the city, which the Gattilusj had held for well-nigh eleven decades. At the same time he pleaded that he had never violated his oaths, never harboured Turkish slaves, but had at once restored them to their owners; and, if he had perforce received pirates to save his own land from their ravages, he had never furnished them with the means of injuring that of the Turks. It was, he added, the fault of his subjects that he had not accepted the Sultan’s generous offer at once, and “I now,” he concluded with tears, “surrender the city and island, begging that my lord may reward me for my good disposition in the past towards him.” Mohammed censured him for his past ingratitude, but promised that it should not be remembered against him. Forthwith a subashi and two men took possession of the upper castle, whence the Frankish garrison was removed but no one else was allowed to issue. The conquerors celebrated their success by a Bacchanalian orgie and by burning the still standing houses of Melanoudion, while the Sultan, setting on one side the chief men among the Franks, bade saw asunder with exquisite cruelty some 300 of the others as pirates in one of the suburbs. Thus, it was said, he had literally carried out their conditions, that their heads should be spared.

The other fortresses in the island—Molivos (or Augerinos), the castle of the two SS. Theodores, and Eresos—now surrendered; for the wretched Nicolò, by the Sultan’s commands, sent a notary with instructions under his own seal, ordering his officers to open their gates. The countryfolk were left undisturbed, but any suspects found there were removed; and later on, one or two of these places were destroyed, and their inhabitants transported, like those of the Foglie, to Constantinople. On the second day after the occupation of the capital, a herald summoned all the citizens to file past the Sultan’s pavilion one by one. On September 17 the sorrowful procession took place; three clerks noted down the names of each, of the most pleasing maidens and the children several hundreds were picked out, and the rest of the population was divided into three classes—the worthless were left behind in the city, others were sold by public auction on the beach, and others again driven on board ship like so many sheep, to await slavery and fill the gaps at Constantinople. But of the 10,000 and more who were shipped from Lesbos a part perished on the overcrowded ships; and with brutal, if business-like precision, all disputes as to the ownership of these human cattle were obviated by cutting off the right ear of each corpse, before it was flung into the deep, and removing the victim’s name from the list. Some 200 janissaries and 300 infantry were left to garrison the city under Ali Bestami, a man of great courage and learning.

The fleet, bearing Nicolò, Luchino, the Archbishop Leonardo, and the rest of the captives, reached Constantinople on October 16, where some of them received houses, or sites in one quarter of the city. The two Gattilusj, however, were soon afterwards imprisoned in the “tower of the French.” Mohammed disliked Nicolò for what he had done in the past, and the chronique scandaleuse of the capital attributed his feelings to the fact that a lad attached to the Turkish court had fled to Lesbos, abandoned Islâm, and become the favourite of Nicolò. After the fall of Lesbos, this youth was sent as a present to the Sultan, and recognised by his comrades, who told their master and thus rekindled his indignation. The two prisoners, to save their lives and regain their freedom, offered to abjure Christianity, and were duly circumcised, gorgeously apparelled by the Sultan, and set free. But their liberty did not last long; they were again imprisoned, and executed, Nicolò being strangled with a bow-string, as he had strangled his own brother. His lovely sister Maria, widow of the Emperor Alexander of Trebizond, whom Mohammed had previously captured in Kolchis, entered the seraglio; her only son became one of the Conqueror’s favourite pages.

Thus ended the rule of the Gattilusj in Lesbos. Had Nicolò been bolder, had Genoa given more help, had Venice not played the part of a spectator, the island might have been saved, or at least its capture postponed. At the time of the siege, Vettor Capello was at Chios, and, in answer to Nicolò’s appeal, actually set out with 29 galleys towards Lesbos; but, although he could have burnt the Turkish fleet in the absence of its crews, he durst not disobey his instructions, which were to avoid giving any offence to the Sultan. Even after the capture of Mytilene, when the people of the castle of the two SS. Theodores begged him to accept them as Venetian subjects, he refused. Later on, when war broke out with Turkey, Venice repented her inaction, and tried in vain to make reparation for it. Even Genoa took the “calamity of Mytilene” with philosophy[632].

Christendom did not, however, abandon all hope of recovering what the Gattilusj had lost. The learned Archbishop of Lesbos, a second time the prisoner of the Turks, wrote to Pius II, as he had written to Nicholas V after the capture of Constantinople, a letter describing the sufferings of his flock and begging the Pope to make peace in Italy and war upon “the Cerberus” of the East. Pius responded by planning a new crusade, and the Genoese suggested that its first stage should be the recapture of Lesbos[633]. The Pope’s death ended his plans; but early in 1464 a Venetian fleet under Luigi Loredano occupied Lemnos with the assistance of a Moreote pirate, who bore the great name of Comnenos. This man had descended upon the island some time before with two galleys, had captured it from the officials who were governing it for Demetrios Palaiologos, and had established his authority over the citadel and the old city of Lemnos. But the pirate saw that he was not strong enough to hold his conquest single-handed, and therefore transferred it to the maritime Republic, which thence easily extended her sway over the rest of the island. Venice retained Lemnos for 15 years, and five Venetian nobles successively administered, with the title of “Rector,” this distant outpost[634]. In April of the same year Orsato Giustiniano, Loredano’s successor, laid siege to Mytilene, but, after six weeks spent before the walls and two battles, in which the Venetians sustained heavy losses, on the approach of the Turkish fleet withdrew to Eubœa with all the Christian islanders whom he could convey, only returning to SS. Theodores to remove a second cargo. Giustiniano died of grief at his failure, and the Turkish sway over Lesbos, despite three subsequent attempts, had never been broken till the Greek fleet took the island on November 22, 1912[635].
