The red tide of slaughter surged up to the very walls of the Palace. Only a few yards separated the foremost ranks of the victorious assailants from the little group of officers, in the midst of which towered the majestic figure of the White Tsar--an emperor without an empire, a leader without an army. He strode forward towards the line of bayonets fringing the crest of the hill, drew his sword, snapped the blade as a man would break a dry stick, and threw the two pieces to the ground, saying in English as he did so-- "It is enough, I surrender!" Then he turned on his heel, and with bowed head walked back again to his Staff. Almost at the same moment a blaze of white light appeared in the sky, a hundred feet above the heads of the vast throng that encircled the Palace. Millions of eyes were turned up at once, and beheld a vision which no one who saw it forgot to the day of his death. The ten air-ships of the Terrorist fleet were ranged in two curves on either side of the _Ithuriel_, which floated about twenty feet below them, her silvery hull bathed in a flood of light from their electric lamps. In her bow, robed in glistening white fur, stood Natasha, transfigured in the full blaze of the concentrated searchlights. A silence of wonder and expectation fell upon the millions at her feet, and in the midst of it she began to sing the Hymn of Freedom. It was like the voice of an angel singing in the night of peace after strife. Men of every nation in Europe listened to her entranced, as she changed from language to language; and when at last the triumphant strains of the Song of the Revolution came floating down from her lips through the still night air, an irresistible impulse ran through the listening millions, and with one accord they took up the refrain in all the languages of Europe, and a mighty flood of exultant song rolled up in wave after wave from earth to heaven,--a song at once of victory and thanksgiving, for the last battle of the world-war had been lost and won, and the valour and genius of Anglo-Saxondom had triumphed over the last of the despotisms of Europe. CHAPTER XLVII. THE JUDGMENT OF NATAS. The myriad-voiced chorus of the Song of the Revolution ended in a mighty shout of jubilant hurrahs, in the midst of which the _Ariel_ dropped lightly to the earth, and Tremayne, dressed now in the grey uniform of the Federation, with a small red rosette on the left breast of his tunic, descended from her deck to the ground with a drawn sword in his hand.
