A circumstance that distinguishes the siege of Constantinople, is the reunion of the ancient and modern artillery. The cannon were intermingled with the mechanical engines for casting stones and darts; the bullet and the battering-ram were directed against the same walls; nor had the discovery of gunpowder superseded the use of the liquid and unextinguishable fire. A wooden turret of the largest size was advanced on rollers; the tower of St. Romanus was at length overturned; after a severe struggle, the Turks were repulsed from the breach, and interrupted by darkness. Of this pause of action, this interval of hope, each moment was improved by the activity of the emperor and Justiniani, who passed the night on the spot, and urged the labours which involved the safety of the church and city. At the dawn of day, the impatient sultan perceived, with astonishment and grief, that his wooden turret had been reduced to ashes; the ditch was cleared and restored; and the tower of St. Romanus was again strong and entire. He deplored the failure of his design; and uttered a profane exclamation, that the word of the thirty-seven thousand prophets should not have compelled him to believe that such a work, in so short a time, could have been accomplished by the infidels.
In the first apprehension of a siege, Constantine had negotiated, in the isles of the Archipelago, the Morea, and Sicily, the most indispensable supplies. Five great ships, equipped for merchandise and war, sailed from the harbour of Chios. One of these ships bore the imperial flag; the remaining four belonged to the Genoese; and they were laden with wheat and barley, with wine, oil, and vegetables, and above all, with soldiers and mariners, for the service of the capital. The Turkish fleet at the entrance of the Bosporus, was stretched from shore to shore, in the form of a crescent, to intercept these bold auxiliaries. The reader who has present to his mind the geographical picture of Constantinople, will conceive and admire the greatness of the spectacle.
The five Christian ships continued to advance with joyful shouts, and a full press both of sails and oars, against a hostile fleet of three hundred vessels; and the rampart, the camp, the coasts of Europe and Asia, were lined with innumerable spectators, who anxiously awaited the event of this momentous succour. At the first view that event could not appear doubtful; the superiority of the Moslems was beyond all measure or account; and, in a calm, their numbers and valour must inevitably have prevailed. But their hasty and imperfect navy had been created, not by the genius of the people, but by the will of the sultan; in the height of their prosperity, the Turks have acknowledged that if God had given them the earth, he had left the sea to the infidels; and a series of defeats, a rapid progress of decay, has established the truth of their modest confession. In this conflict, the imperial vessel, which had been almost overpowered, was rescued by the Genoese; but the Turks, in a distant and closer attack, were twice repulsed with considerable loss.
Muhammed himself sat on horseback on the beach to encourage their valour by his voice and presence, by the promise of reward, and by fear more potent than the fear of the enemy. The passions of his soul, and even the gestures of his body, seemed to imitate the actions of the combatants; and, as if he had been the lord of nature, he spurred his horse with a fearless and impotent effort into the sea. His loud reproaches, and the clamours of the camp, urged the Ottomans to a third attack, more fatal and bloody than the two former; and we must repeat, though we cannot credit, the evidence of Phrantzes, who affirms from their own mouth that they lost above twelve thousand men in the slaughter of the day. The Christian squadron, triumphant and unhurt, steered along the Bosporus, and securely anchored within the chain of the harbour.
The reduction of the city appeared to be hopeless, unless a double attack could be made from the harbour as well as from the land; but the harbour was inaccessible; an impenetrable chain was now defended by eight large ships, more than twenty of a smaller size, with several galleys and sloops; and instead of forcing this barrier, the Turks might apprehend a naval sally, and a second encounter in the open sea.
In this perplexity, the genius of Muhammed conceived and executed a plan of a bold and marvellous cast, of transporting by land his lighter vessels and military stores from the Bosporus into the higher part of the harbour. The distance is about ten miles; the ground is uneven, and was overspread with thickets; and, as the road must be opened behind the suburb of Galata, their free passage or total destruction must depend on the option of the Genoese. But these selfish merchants were ambitious of the favour of being the last devoured; and the deficiency of art was supplied by the strength of obedient myriads. A level way was covered with a broad platform of strong and solid planks; and to render them more slippery and smooth, they were anointed with the fat of sheep and oxen. Fourscore light galleys and brigantines of fifty and thirty oars were disembarked on the Bosporus shore; arranged successively on rollers; and drawn forward by the power of men and pulleys. Two guides or pilots were stationed at the helm and the prow of each vessel; the sails were unfurled to the winds; and the labour was cheered by song and acclamation. In the course of a single night, this Turkish fleet painfully climbed the hill, steered over the plain, and was launched from the declivity into the shallow waters of the harbour, far above the molestation of the deeper vessels of the Greeks. The real importance of this operation was magnified by the consternation and confidence which it inspired; but the notorious, unquestionable fact was displayed before the eyes, and is recorded by the pens, of the two nations. A similar stratagem had been repeatedly practised by the ancients.
As soon as Muhammed had occupied the upper harbour with a fleet and army, he constructed, in the narrowest part, a bridge or rather mole of fifty cubits in breadth, and one hundred in length; it was formed of casks and hogsheads, joined with rafters linked with iron and covered with a solid floor. On this floating battery he planted one of his largest cannon, while the fourscore galleys, with troops and scaling-ladders, approached the most accessible side, which had formerly been stormed by the Latin conquerors. His vigilance prevented the approach of the Greek ships; their foremost galliots were sunk or taken; forty youths, the bravest of Italy and Greece, were inhumanly massacred at his command; nor could the emperor’s grief be assuaged by the just though cruel retaliation, of exposing from the walls the heads of 260 Mussulman captives.
After a siege of forty days, the fate of Constantinople could no longer be averted. The diminutive garrison was exhausted by a double attack; the fortifications which had stood for ages against hostile violence, were dismantled on all sides by the Ottoman cannon; many breaches were opened; and near the gate of St. Romanus, four towers had been levelled with the ground. For the payment of his feeble and mutinous troops, Constantine was compelled to despoil the churches, with the promise of a fourfold restitution; and his sacrilege offered a new reproach to the enemies of the union. A spirit of discord impaired the remnant of the Christian strength; the Genoese and Venetian auxiliaries asserted the pre-eminence of their respective service; and Justiniani and the grand duke, whose ambition was not extinguished by the common danger, accused each other of treachery and cowardice.
During the siege of Constantinople, the words of peace and capitulation had been sometimes pronounced; and several embassies had passed between the camp and the city. The Greek emperor was humbled by adversity; and would have yielded to any terms compatible with religion and royalty. The Turkish sultan was desirous of sparing the blood of his soldiers; still more desirous of securing for his own use the Byzantine treasures; and he accomplished a sacred duty in presenting to the gabours the choice of circumcision, of tribute, or of death. The avarice of Muhammed might have been satisfied with an annual sum of one hundred thousand ducats; but his ambition grasped the capital of the East; to the prince he offered a rich equivalent, to the people a free toleration, or a safe departure; but after some fruitless treaty, he declared his resolution of finding either a throne, or a grave, under the walls of Constantinople.
A sense of honour, and the fear of universal reproach, forbade Palæologus to resign the city into the hands of the Ottomans; and he determined to abide the last extremities of war. Several days were employed by the sultan in the preparations of the assault; and a respite was granted by his favourite science of astrology, which had fixed on the 29th of May as the fortunate and fatal hour. On the evening of the 27th he issued his final orders. A crowd of dervishes visited the tents, to instil the desire of martyrdom, and the assurance of spending an immortal youth amidst the rivers and gardens of paradise and in the embraces of the black-eyed virgins. Yet Muhammed principally trusted to the efficacy of temporal and visible rewards. A double pay was promised to the victorious troops; “The city and the buildings,” said Muhammed, “are mine; but I resign to your valour the captives and the spoil, the treasures of gold and beauty; be rich and be happy. Many are the provinces of my empire: the intrepid soldier who first ascends the walls of Constantinople, shall be rewarded with the government of the fairest and most wealthy; and my gratitude shall accumulate his honours and fortunes above the measure of his own hopes.” Such various and potent motives diffused among the Turks a general ardour, regardless of life, and impatient for action; the camp re-echoed with the Moslem shouts of “God is God, there is but one God, and Mohammed is the apostle of God;” and the sea and land, from Galata to the Seven Towers, were illuminated by the blaze of their nocturnal fires.
