"This successful move upon the part of our Boys in Blue was followed by an ominous lull or quiet, which continued about three hours. Meanwhile the silence was fitfully broken by an occasional spit of fire, while every preparation was being made for a last, supreme effort, which it was expected would decide the mighty contest. The scales were being poised for the last time, and upon the one side or the other was soon to be recorded a glorious victory or a disastrous defeat. Hearts either trembled, or waxed strong in the awful presence of this responsibility. "At length one o'clock arrived, a signal-gun was fired, and then at least one hundred and twenty-five guns from Hill and Longstreet concentrated and crossed their fires upon Cemetery Hill, the centre and key of our position. Just behind this crest, though much exposed, were General Meade's headquarters. For nearly two hours this hill was plowed and torn by solid shot and bursting shell, while about one hundred guns on our side, mainly from this crest and Round Top, made sharp response. The earth and the air shook for miles around with the terrific concussion, which came no longer in volleys, but in a continual roar. So long and fearful a cannonade was never before witnessed on this continent. As the range was short and the aim accurate, the destruction was terrible. * * * * * "Gradually the fire on our side began to slacken, and General Meade, learning that our guns were becoming hot, gave orders to cease firing and to let the guns cool, though the rebel balls were making fearful havoc among our gunners, while our infantry sought poor shelter behind every projection, anxiously awaiting the expected charge. At length the enemy, supposing that our guns were silenced, deemed that the moment for an irresistible attack had come. Accordingly, as a lion emerges from his lair, he sallied forth, when strong lines of infantry, nearly three miles in length, with double lines of skirmishers in front, and heavy reserves in rear, advanced with desperation to the final effort. They moved with steady, measured tread over the plain below, and began the ascent of the hills occupied by our forces, concentrating somewhat upon General Hancock, though stretching across our entire front. * * * * * "General Picket's division was nearly annihilated. One of his officers recounted that, as they were charging over the grassy plain, he threw himself down before a murderous discharge of grape and canister, which mowed the grass and men all around him as though a scythe had been swung just above his prostrate form.
