A few minutes later a continuous roll of musketry burst out on front, and flank, and rear, and a ceaseless hail of rifle bullets began to plough its way through the helpless masses of the soldiers of the Tsar. They formed as well as they could to confront these new enemies, but the moment that the searchlight of the air-ship, constantly sweeping the field, fell upon a company in anything like order, a shell descended in the midst of it and broke it up again. All night long the work of death and vengeance went on; the grey lines ever closing in nearer and nearer upon the dwindling remnants of the Russian army. Hour after hour the hail of bullets never slackened. There was no random firing on the part of the Federation soldiers. Every man had been trained to use his rifle rapidly but deliberately, and never to fire until he had found his mark; and the consequence was that the long nickel-tipped bullets, fired point-blank into the dense masses of men, rent their way through half a dozen bodies before they were spent. At last the grey light began to break over an indescribably hideous scene of slaughter. Scarcely ten thousand men remained of the three hundred thousand who had started the day before in obedience to the order of the Tsar; and these were split up into formless squads and ragged companies fighting desperately amidst heaps of corpses for dear life, without any pretence at order or formation. The cannonade from the air had ceased, and the last scene in the drama of death had come. With bayonets fixed and rifles lowered to the charge, the long grey lines closed up, and, as the bugles rang out the long-awaited order, they swept forward at the double, horses and men went down like a field of standing corn under the irresistible rush of a million bayonets, and in twenty minutes all was over. Not a man of the whole Russian army was left alive, save those whose knot of red ribbon at the button-hole proclaimed them members of the International. As soon as it was light enough for Arnold to see clearly that the fate of the Russians was finally decided, he descended to the earth, and, after complimenting the commander and officers of the Federation troops on the splendid effectiveness of their force, and their admirable discipline and coolness, he gave orders for a two hours' rest and then a march on the Russian headquarters at Muswell Hill with every available man. The Tsar and his Staff were to be taken alive at all hazards; every other Russian who did not wear the International ribbon was to be shot down without mercy.
