All this had taken but a minute of time, and now the second Confederate line swept down and poured in its fire. The line of blue staggered and gave way; in those two terrific volleys it seemed to have quite poured out its spirit. To this deadly work our reserve regiment now came up with a run. It was surprising to see it spitting fire with never a sound, for such was the infernal din that the ear could take in no more. This fearful scene was enacted within fifty paces of our toes, but we were rooted to the ground as if we had grown there. But now our commanding officer rode from behind us to the front, waved his hand with the courteous gesture that says _apres vous_, and with a barely audible cheer we sprang into the fight. Again the smoking front of gray receded, and again, as the enemy's third line emerged from its leafy covert, it pushed forward across the piles of dead and wounded to threaten with protruded steel. Never was seen so striking a proof of the paramount importance of numbers. Within an area of three hundred yards by fifty there struggled for front places no fewer than six regiments; and the accession of each, after the first collision, had it not been immediately counterpoised, would have turned the scale. As matters stood, we were now very evenly matched, and how long we might have held out God only knows. But all at once something appeared to have gone wrong with the enemy's left; our men had somewhere pierced his line. A moment later his whole front gave way, and springing forward with fixed bayonets we pushed him in utter confusion back to his original line. Here, among the tents from which Grant's people had been expelled the day before, our broken and disordered regiments inextricably intermingled, and drunken with the wine of triumph, dashed confidently against a pair of trim battalions, provoking a tempest of hissing lead that made us stagger under its very weight. The sharp onset of another against our flank sent us whirling back with fire at our heels and fresh foes in merciless pursuit--who in their turn were broken upon the front of the invalided brigade previously mentioned, which had moved up from the rear to assist in this lively work.
