So she sped along the whole line, darting hither and thither in obedience to the guiding hand that controlled her, with such inconceivable rapidity that before any of the unwieldy machines, saving only those whose occupants had been prepared for the assault, had time to get out of the way of the destroying ram, she had rent her way through the gas-holders of twenty-eight out of the forty balloons, and flung them to the earth to explode and spread consternation and destruction all along the van of the army encamped below. From beginning to end the attack had not lasted ten minutes. When the last of the aerostats had gone down under his terrible ram, Arnold signalled "Stop, and ascend," to the engine-room. A second signal turned on the searchlight in the bow, and from this a rapid series of flashes were sent up to the sky to the northward and eastward. [Illustration: "Her ram had passed completely through the gasholder." _See page 334._] The effect was as fearful as it was instantaneous. The twelve war-balloons which had escaped by flying the red flag took up their positions above the Russian lines, and began to drop their fire-shell and cyanogen bombs upon the masses of men below. The air-ship, swerving round again to the westward, with her fan-wheels aloft, moved slowly across the wide area over which men and horses were wildly rushing hither and thither in vain attempts to escape the rain of death that was falling upon them from the sky. Her searchlight, turned downwards to the earth, sought out the spots where they were crowded most thickly together, and then the air-ship's guns came into play also. Arnold had given orders to use the new fire-shell exclusively, and its effects proved to be frightful beyond description. Wherever one fell a blaze of intense light shone for an instant upon the earth. Then this burst into a thousand fragments, which leapt into the air and spread themselves far and wide in all directions, burning with inextinguishable fury for several minutes, and driving men and horses mad with agony and terror. No human fortitude or discipline could withstand the fearful rain of fire, in comparison with which even the deadly hail from the aerostats seemed insignificant. For half an hour the eight guns of the _Ithuriel_ hurled these awful projectiles in all directions, scattering death and hopeless confusion wherever they alighted, until the whole field of carnage seemed ablaze with them. At the end of this time three rockets soared up from her deck into the dark sky, and burst into myriads of brilliant white stars, which for a few moments shed an unearthly light upon the scene of indescribable confusion and destruction below. But they made more than this visible, for by their momentary light could be seen seemingly interminable lines of grey-clad figures swiftly closing in from all sides, chasing the Cossack scouts before them in upon the completely disorganised Russian host.
