CONTINUATION OF THE BOMBARDMENT.—Upon the morning of the 20th, Fort Sumter still stood, notwithstanding its fall had been confidently and speedily anticipated on the night of the 18th; but it was an obstinate and very strong work, and from every flagstaff visible upon it, the blood-red battle-flag of the “Confederate States Army” still floated proudly and defiantly on the breeze. The gorge wall still stood obstinately upright, notwithstanding the fearful fire directed against it from end to end of the Union lines; although the effect of the projectiles was plainly visible. Fort Wagner, too, in defiance of the severe treatment it had received, remained as strong as ever, although its walls showed the bruises of the many and formidable blows which had been levelled against it; and it had now the farther advantage of having been strongly reinforced. Before Sumter could be occupied by the Union troops, it was absolutely necessary to reduce Forts Gregg and Wagner; and active operations to this end were constantly going forward. The storm, which still continued, and at times raged with great violence, rendered it impossible for the monitors to be of any immediate service, although the whole fleet moved up abreast of Fort Sumter on the evening of the 19th, but were obliged to retire without firing a single shot. When the port-holes were opened the heavy ocean swell washed in, and effectually prevented the accurate elevation of the guns. The troops still continued in excellent spirits; though from their confidence of ultimate success, and the monotony of the long continued bombardment, some of them showed a slight disposition to carelessness. But this was speedily put an end to, and the hottest fighting since the opening of the bombardment, began in terrible earnest. The firing increased so rapidly that the loud and continuous roar was absolutely deafening; every battery was at work. At six o’clock in the evening, the entire top of the fort was completely gone, and every parapet gun was dismounted, most of them having fallen into the sea. The flags were of course shot away; the garrison no longer making any effort to return the Union fire, which hardly ceased during the whole day. The southwest side presented a mere mass of ruins, when at length the guns were silenced for the night; and on the next day, nine enormous breaches were visible in the strongest portion of the fort. The firing was again resumed; and, upon rebel authority, “kept up heavier than ever during the 21st.” From five o’clock in the morning, till seven in the evening, nine hundred and twenty-three shots were fired, of which no less than seven hundred and four struck the fort. The Ironsides, on this morning, also opened fire, and Sumter occasionally replied. Fort Wagner fired briskly on the Union advanced works, too, but without doing much damage. The National fire upon Wagner was, however, very destructive, and with every hour continued to grow more so. At eleven P.
