Whole divisions were now overwhelmed by the Rebel hordes, that swept forward amid blazing musketry and battle-shouts which made the wilderness resound; and a frantic stampede commenced which not all the courage and effort of commanding generals, or the intrepidity of some regiments could check, and which threatened to rout the entire army. This unforeseen disaster changed the whole programme of the battle and greatly disheartened our men. However, the ground was not to be abandoned so ingloriously, and though our lines were broken, and the enemy had gained a great advantage, heroism was yet to manifest its grand spirit, and to achieve undying laurels. The sun had gone down, refusing to look upon this Union defeat and slaughter, but the pale-faced moon gazed with her weird light upon the bloody scene, while the carnage still continued. With the disaster of the Eleventh Corps General Sickles, who was stationed in the front and centre of our lines and had been preparing to deal a heavy blow upon the enemy, was left in a critical position. His expectation of assistance from General Howard was not only cut off, but he was left with only two divisions and his artillery to meet the shock of the advancing hosts. General Pleasonton, with his small force of cavalry, being under Sickles' command, was ordered to charge the proud columns of the enemy, with the hope of checking them until our batteries could be suitably planted. Pleasonton, addressing Major Keenan of the Eighth Pennsylvania Cavalry, said, "You must charge into those woods with your regiment, and hold the Rebels until I can get some of these guns into position. You must do it at whatever cost." "I will," was the noble response of the true soldier, who, with only about five hundred men, was to encounter columns at least twenty-five thousand strong, led by Stonewall Jackson! The forlorn charge was made, but the martyr-leader, with the majority of his dauntless troopers, soon baptized the earth upon which he fell, with his life blood. But the precious sacrifice was not in vain. The Rebel advance was greatly checked, as when a trembling lamb is thrown into the jaws of a pursuing pack of ravenous wolves.
