A crash and a stunning shock, as of a falling sphere, aroused me at nine o'clock. A shell had burst in front of our tent, and the enemy's artillery was thundering from Casey's old hill, beyond the swamp. As I hastily drew on my boots,--for I had not otherwise undressed,--I had opportunity to remark one of those unaccountable panics which develop among civilian soldiers. The camps were plunged into disorder. As the shells dropped here and there, among the tents and teams, the wildest and most fearful deeds were enacted. Here a caisson blew up, tearing the horses to pieces, and whirling a cannoneer among the clouds. There an ammunition wagon exploded, and the air seemed to be filled with fragments of wood, iron, and flesh. A boy stood at one of the fires, combing out his matted hair; suddenly his head flew off, spattering the brains, and the shell--which we could not see--exploded in a piece of woods, mutilating the trees. The effect upon the people around me was instantaneous and appalling. Some, that were partially dressed, took to their heels, hugging a medley of clothing. The teamsters climbed into the saddles, and shouted to their nags, whipping them the while. If the heavy wheels hesitated to revolve, they left horses and vehicles to their fate, taking themselves to the woods; or, as in some cases, cut traces and harness, and galloped away like madmen. In a twinkling our camps were almost deserted, and the fields, woods, and roads were alive with fugitives, rushing, swearing, falling, and trampling, while the fierce bolts fell momentarily among them, making havoc at every rod.
To join this flying, dying mass was my first impulse; but after-thought reminded me that it would be better to remain. I must not leave my horse, for I could not walk the whole long way to the James, and the fever had so reduced me that I hardly cared to keep the little life remaining. I almost marvelled at my coolness; since, in the fulness of strength and health, I should have been one of the first of the fugitives; whereas, I now looked interestedly upon the exciting spectacle, and wished that it could be daguerreotyped.
Before our artillery could be brought to play, the enemy, emboldened at his success, pushed a column of infantry down the hill, to cross the creek, and engage us on our camping-ground. For a time I believed that he would be successful, and in that event, confusion and ruin would have overtaken the Unionists. The gray and butternut lines appeared over the brow of the hill,--they wound at double quick through the narrow defile,--they poured a volley into our camps when half-way down, and under cover of the smoke they dashed forward impetuously, with a loud huzza. The artillery beyond them kept up a steady fire, raining shell, grape, and canister over their heads, and ploughing the ground on our side, into zigzag furrows,--rending the trees, shattering the ambulances, tearing the tents to tatters, slaying the horses, butchering the men. Directly Captain Mott's battery was brought to bear; but before he could open fire, a solid shot struck one of his twelve-pounders, breaking the trunnion and splintering the wheels. In like manner one of his caissons blew up, and I do not think that he was able to make any practise whatever. A division of infantry was now marched forward, to engage the Confederates at the creek side; but two of the regiments--and I think that one was the 20th New York--turned bodily, and could not be rallied. The moment was full of significance, and I beheld these failures with breathless suspense. In five minutes the pursuers would gain the creek, and in ten, drive our dismayed battalions, like chaff before the wind. I hurried to my horse, that I might be ready to escape. The shell and ball still made music around me. I buckled up my saddle with tremulous fingers, and put my foot upon the stirrup. But a cheer recalled me and a great clapping of hands, as at some clever performance in the amphitheatre. I looked again. A battery from our position across the road, had opened upon the Confederate infantry, as they reached the very brink of the swamp. For a moment the bayonets tossed wildly, the dense column staggered like a drunken man, the flags rose and fell, and then the line fell back disorderly. At that instant a body of Federal infantry, that I had not seen, appeared, as by invocation; their steel fell flashingly, a column of smoke enveloped them, the hills and skies seemed to split asunder with the shock,--and when I looked again, the road was strewn with the dying and dead; the pass had been defended.
