Those brave troops had heard the tramp of thousands of cavalry, sweeping battle without fear, but now they stood in still terror, before the march of the conflagration, under whose burning footsteps was heard the incessant crash of falling houses, and palaces, and churches. The continuous roar of the raging hurricane, mingled with that of the flames, was more terrible than the thunder of artillery; and before this new foe, in the midst of this battle of the elements, the awe-struck army stood powerless and affrighted. When night descended again on the city, it presented a spectacle, the like of which was never seen before, and which baffles all description: the streets of fire, the heavens a canopy of fire, and the entire body of the city a mass of fire, fed by a hurricane that whirled the blazing fragments in a constant stream through the air. Incessant explosions, from the blowing up of stores of oil, and tar, and spirits, shook the very foundations of the city, and sent volumes of smoke rolling furiously toward the sky. Huge sheets of canvas, on fire, came floating, like messengers of death, through the flames; the towers and domes of the churches and palaces, glowed with red-hot heat over the wild sea below, then tottering a moment on their bases, were hurled by the tempest into the common ruin. Thousands of wretches, before unseen, were driven by the heat from the cellars and hovels, and streamed in an incessant throng through the streets. Children were seen carrying their parents,--the strong the weak,--while thousands more were staggering under loads of plunder, they had snatched from the flames. This, too, would frequently take fire in the falling shower, and the miserable creatures would be compelled to drop it and flee for their lives. Oh, it was a scene of woe and fear indescribable! A mighty and close packed city of houses, and churches, and palaces, wrapt from limit to limit in flames, which are fed by a whirling hurricane, is a sight this world will seldom see. But this was all within the city. To Napoleon, without, the spectacle was still more sublime and terrific. When the flames had overcome all obstacles, and had wrapped everything in their red mantle, that great city looked like a sea of fire, swept by a tempest that drove it into vast billows. Huge domes and towers, throwing off sparks like blazing firebrands, now towered above these waves, and now disappeared in their maddening flow, as they rushed and broke high over tops, and scattered their spray of fire against the clouds. The heavens themselves seemed to have caught the conflagration, and the angry masses that swept it, rolled over a bosom of fire. Columns of flame would rise and sink along the surface of the sea, and huge volumes of black smoke suddenly shoot into the air, as if volcanoes were working below.
