Tom Somers floated with the tide of humanity that was setting away from the scene of disaster and defeat. The panic that prevailed was even more fearful than the battle, for wounded and dying men were mercilessly trodden down by the feet of the horses, and run over by the wheels of the cannon and the baggage wagons. Though the battle was ended, the rebels still poured storms of shot and shell into the retreating, panic-stricken host. Tom did not know where to go, for there were panic and death on all sides of him. The soldiers were flying in every direction, some of them into the very arms of their remorseless enemies. But the woods seemed to promise the most secure retreat from the fury of the Black Horse Cavalry, which was now sweeping over the battle-field. The Zouave ran in this direction, and our soldier boy followed him. Now that the excitement of the conflict was over, the enthusiasm which had buoyed him up began to subside. The day was lost; all hopes of glory had fled; and a total defeat and rout were not calculated to add much strength to his over-tasked limbs. He was nearly used up, and it was hard work to run--very hard work; and nothing but the instinct of self-preservation enabled him to keep the tall and wiry form of the Zouave in sight. They reached the ravine, where the water was about three feet deep. The shot, and shell, and bullets still fell in showers around them, and occasionally one of the luckless fugitives was struck down. They crossed the stream, and continued on their flight. An officer on horseback dashed by them, and bade them run with all their might, or they would be taken. "For Heaven's sake, get me some water!" said a rebel, who was wounded in the leg, to a Zouave, who passed near him. "You are a rebel, but I will do that for you," replied the Zouave; and he gave him a canteen filled with water. The rebel drank a long, deep draught, and then levelled his musket at the head of his Samaritan enemy and fired. This transaction had occupied but a moment, and Tom saw the whole. His blood froze with horror at the unparalleled atrocity of the act. The Zouave, whom Tom had followed, uttered a terrible oath, and snatching the musket from the hands of the soldier boy, he rushed upon the soulless miscreant, and transfixed him upon the bayonet. Uttering fierce curses all the time, he plunged the bayonet again and again into the vitals of the rebel, till life was extinct. "Boy, I used to be human once," said the Zouave, when he had executed this summary justice upon the rebel; "but I'm not human now. I'm all devil." "What a wretch that rebel was!" exclaimed Tom, who seemed to breathe freer now that retribution had overtaken the viper. "A wretch! Haven't you got any bigger word than that, boy? He was a fiend! But we mustn't stop here." "I thought the rebels were human." "Human? That isn't the first time to-day I've seen such a thing as that done. Come along, my boy; come along."
