On the 23rd of June 1204 the crusading fleet anchored at San Stefano. Thence they saw the magnificent city that lay before them. "Be sure," says Villehardouin, "there was not a man who did not tremble, because never was so great an enterprise undertaken by so small a number of men." Next day they sailed up to the Bosphorus, past the walls, crowded with spectators, to the anchorage of Chalcedon. The Emperor sent to know their intentions: they ordered him to surrender the crown to the young Alexius. Then came another of those picturesque scenes of which the mediæval history of the New Rome is so full. It was determined to show the young prince to the people whom he came to recover to their allegiance. The splendid Venetian galleys sailed up to the walls of the Sea of Marmora, and stopped where the crowds that thronged them could see. Then loud voices proclaimed the presence of the young Alexius, and demanded the loyal assent of the people to the restoration of his father. Only mocking laughter came back from the walls. Then the Crusaders prepared for the attack. First it was necessary to break the chain which crossed the Golden Horn from Galata, near what is now Tophané, to near the point of the peninsula of Byzantium. A fierce attack was made on the watch-tower at Galata, from which the chain began. It was captured, the chain was loosed, and the fleet sailed up the Golden Horn. The army was then landed beyond the walls, where is now Eyoub, and took up a position opposite the Blachernae quarter, which had so long been felt to be the weakest point. They were opposed then by the wall of Manuel Comnenus which extended southward of the wall of Heraclius, and considerably in advance of the old Theodosian fortification. Moats, walls, towers, stood before them, a defence hitherto unbroken, and which even before the last fortification was erected it had been found impossible to overthrow. And so it proved again. When the attack on July 17, 1203, was directed against the northern point of the wall of the Blachernae quarter, near the Xylo-porta, it was utterly defeated. And so again when Dandolo, the old blind Doge, dauntless in bravery as adept in cunning, led the attack from his galleys, their success was but temporary. The old sea-dog had his galley drawn up close to the walls, threw himself on shore, on the narrow strip of land that stood between the water and the walls, and planted the gonfalon of S. Mark on one of the towers. The ends of the flying bridges were thrust from the vessels on to the towers and thus twenty-five were captured. But the Venetians could not maintain their position, and when the Greeks were reported to have made a sortie from the gate of S. Romanus, south of the Blachernae quarter, they withdrew to help these other Crusaders who were attacked.
