I reached over and gripped his hand hard. “It will be the first thing I shall remember, Jack,” I answered earnestly. “But we may have it easy enough after all--it seems to be an infantry affair.” He shook his head gravely. “No,” he said, pointing forward, “they will need us now.” As he spoke it seemed as though the sharp firing upon both sides suddenly ceased by mutual consent. The terrible roar of small arms, which had mingled with the continuous thunder of great guns, died away into an intermittent rattling of musketry, and as the heavy smoke slowly drifted upward in a great white cloud, we could plainly distinguish the advancing Federal lines, three ranks deep, stretching to left and right in one vast, impenetrable blue wall, sweeping toward us upon a run. Where but a brief moment before the plain appeared deserted, it was now fairly alive with soldiery, the sun gleaming on fixed bayonets, and faces aglow with the ardor of surprise. Some one had blundered! The thin, unsupported line of gray infantry directly in our front closed up their shattered ranks hastily in desperate effort to stay the rush. We could see them jamming their muskets for volley fire, and then, with clash and clatter that drowned all other sounds, a battery of six black guns came flying madly past us, every horse on the run, lashed into frenzy by his wild rider. With carriage and caisson leaping at every jump, the half-naked, smoke-begrimed cannoneers clinging to their seats like monkeys, they dashed recklessly forward, swung about into position, and almost before the muzzles had been well pointed, were hurling canister into that blue, victorious advance. How those gallant fellows worked! their guns leaping into air at each discharge, their movements clockwork! Tense, eager, expectant, every hand among us hard gripped on sabre hilt, we waited that word which surely could not be delayed, while from end to end, down the full length of our straining line, rang out the yell of exultant pride. “Steady, men; steady there, lads!” called the old Colonel, sternly, his own eyes filled with tears. “Our turn will come.”
