The recovery of Constantinople from the Latins in 1261 did not diminish Italian influence over the life of the city. On the contrary, from that time to the close of Byzantine history that influence, modified indeed by the rival force of Ottoman power, grew stronger and stronger. Commercial interests, political necessities, schemes of ecclesiastical union, literary sympathies, possibilities of aggrandisement at the expense of an Empire hastening to ruin, made Italy, especially Genoa and Venice, take a most active part in the affairs of New Rome. A Western atmosphere, so to speak, then enveloped Constantinople, very much like that which surrounds the City of the Sultans to-day.
But the portion of the walls about which the greatest and most pathetic interest gathers is where Sultan Mehemet delivered his fatal blow upon the Byzantine Empire, and won the title of “the Conqueror.” It is the portion which stretches from Top Kapoussi (Gate of S. Romanus) to Edirné Kapoussi (Gate of Charisius), across the ravine through which the little stream of the Lycus, on its way to the Sea of Marmora, enters the city. Owing to the depression of the ground and the impossibility of constructing a deep moat there, this was the weakest point in the Theodosian fortifications, and here the bravest of the defenders, under Giustiniani of Genoa and the Emperor Constantine, manned the walls to oppose the best troops under the command of the Sultan. Against this part of the walls the enemy pointed his heaviest cannon, and here the contest raged for more than seven weeks. Both the besieged and the besiegers fought with the determination and the valour worthy of the issues at stake. When the Turkish artillery broke down the Outer Wall, Giustiniani and his Genoese and Greek comrades held their ground, and replaced the fallen ramparts by a stockade built of stones, barrels full of earth, beams, branches of trees--of anything within reach that would hold together. Against that barricade wave after wave of Turkish troops dashed and beat furiously and long. There were moments when the defenders seemed to have gained the day. But like gleams of sunshine that pierce storm clouds, they only served to make the impending catastrophe more tragic. Giustiniani was wounded and left the field. A band of bold Turks entered the city through the postern of the Kerkoporta, thoughtlessly left open, and, mounting the walls, planted their banners upon the parapet. Anon, the cry “The city is taken” burst upon the air and reverberated from tower to tower. A panic seized the besieged. The Sultan, grasping his opportunity, roused his janissaries to a supreme effort, and hurled them against the battered and half-deserted barricade. The Emperor Constantine did everything in his power to rally his followers and repel the terrible onset. It was hopeless. He then sought and found a soldier’s death, rather than survive the fall of his Empire. “All was lost save honour.” And over his dead body the tide of conquest poured into the city.
