"Brothers and fellow-soldiers, be ready for the morn. If God gives us grace and valour, and the Holy Trinity help us, in Whom alone we trust, we will do such deeds that the foe shall fall back with shame before our arms." Then, says the chronicler, the wretched Romans strengthened their hearts like lions, sought and gave pardon, and with tears embraced each other as though mindful no more of wife or children or earthly goods, but only of death, which, for the safety of their country, they were glad to undergo. Constantine for the last time went to the great church, and there, before all the bishops, asked the pardon of all whom he had wronged. Then he received his last communion. For the last time the Holy Sacrifice was offered in S. Sophia, and then the last of the Cæsars and his nobles went forth to die. Before cock-crow he was again at his post; and with the first streak of dawn the Turkish troops poured forth to the attack. Again and again they were forced back, and again forced forward by the troops behind them. The moat had been filled with earth and stones; but a great palisade of stones covered with hides had been set up below the inner wall. The Janissaries at length rushed up to the breach, but even they were driven back. The critical moment came when a wound compelled Giustiniani to retire, and a few minutes after the Turks discovered a gate in the outer wall that had been newly opened, near to the gate of Charisius, and below the palace of the Porphyrogenitus, found it unprotected, and entering through it turned upon the defenders from within. Already the Genoese had left their posts when their leader withdrew. The Janissaries again advanced; they stormed the barricade, and at the moment when some discovered the Kerko-porta,[31] others forced their way through the gate of Charisius, and others through the great breach near where the great Cæsar had stood. When the city was entered he was in the street calling his men around him. He rode forward, cutting his way through the foe, with some of the bravest of his nobles round him. At length he fell, near the gate of S. Romanus, by an unknown hand, and the conquering Turks swept over his body. The age-long fight which the Imperial East had waged against barbarism was over. The city of the Cæsars and the Church was in the hands of the infidel. The land where the scholarship of the ancient world and the law of the pioneers of equal justice had been preserved unbroken, was now trodden under foot of those whose life was formed on quite other models. Europe had stood by for centuries and watched the gallant battle waged by the Christians who manned the bulwarks of her civilisation. She had now to learn what was meant by the substitution of the Koran for the Bible, of Mohammed for Christ.
