Meantime the Doge placed a fleet in the Golden Horn, in line along the eastern wall of the city, and began his attack in earnest. Wherever the danger was greatest there was the Doge; and his achievements are almost beyond belief, when his great age and weak sight are remembered. Gibbon was not over-fond of the Venetians; let us quote his tribute to them on this proud day:-- {51} "On the side of the harbor the attack was more successfully conducted by the Venetians; and that industrious people employed every resource that was known and practised before the invention of gunpowder. A double line, three bowshots in front, was formed by the galleys and ships; and the swift motion of the former was supported by the weight and loftiness of the latter, whose decks and poops and turrets were the platforms of military engines that discharged their shot over the heads of the first line. The soldiers who leaped from the galleys on shore immediately planted and ascended their scaling-ladders, while the large ships, advancing more slowly into the intervals and lowering a drawbridge, opened a way through the air from their masts to the rampart. "In the midst of the conflict the Doge's venerable and conspicuous form stood aloft in complete armor on the prow of his galley. The great standard of St. Mark was displayed before him; his threats, promises, and exhortations urged the diligence of the rowers; his vessel was the first that struck; and Dandolo was the first warrior on shore. The nations admired the magnanimity of the blind old man, without reflecting that his age and infirmities diminished the price of life and enhanced the value of immortal glory. On a sudden, by an invisible hand (for the standard-bearer was probably slain), the banner of the Republic was fixed on the rampart, twenty-five towers were rapidly occupied, and, by the cruel expedient of fire, the Greeks were driven from the adjacent quarter." Fearful for the fate of the French, Dandolo now hastened to their relief with his troops. The Emperor Alexius had made a sally, but the aspect of his foes terrified him more and more. At evening he withdrew his forces, and in the darkness of the night, taking £10,000 and many rich jewels with him, by the way of the Bosphorus he reached obscurity in Thrace. He deserted his throne and his people, his wife and his children, taking with him his daughter Irene alone.
