Three picked regiments were assigned the duty of storming this fort by General Longstreet. On the night of the twenty-eighth of November these regiments succeeded in pushing their way through the pine abattis, reaching the edge of the clearing, after a short interval of skirmishing with the defenders, and lay on their arms at the edge of the abattis until daybreak on the morning of the twenty-ninth, when a charge was ordered. A scene of carnage and desperate valor now ensued, which had many parallels during this fratricidal war. As the rebels advanced across the open space, a furious storm of grape and canister met them, and decimated their ranks. A network of unseen wires, which had been interlaced across the approach, now entangled their ranks, and threw many of the men to the ground, who were trampled under feet by their comrades. The air was filled with the whiz of minie balls. Yet still the intrepid assailants rushed on, over the bodies of their dead and wounded comrades, until they reached the ditch, where they encountered a continuous storm of hand-grenades thrown into the midst of the struggling mass, and exploding with horrible effect. One of the assailants reached the parapet, and waved a Confederate flag, only to be hurled into the ditch the next instant, a mangled corpse. None of the rebels entered the fort, while scores lay dead before it. The whole force of the garrison was but three hundred—far less than the dead and dying who strewed the ground around it. The Federal loss was four killed and eleven wounded. General Longstreet, now despairing of success, abandoned the siege, and retreated southward. On the sixth of December General Sherman entered the city with reinforcements, and railroad communication with Chattanooga was opened. OPERATIONS IN TENNESSEE. SEPTEMBER 20-DECEMBER 31, 1863. The great battle of Chickamauga, ending on the 20th of September, 1863, resulted, as we have seen, in no material advantage to the rebels and in no additional success to the arms of the Union. It was substantially an equal and a fruitless contest—“a drawn battle.” Upon both sides the losses were very heavy. General Rosecrans lost sixteen thousand eight hundred and fifty-one men, all told, and a large quantity of material of war. General Bragg, on the other hand, lost eighteen thousand. Upward of two thousand rebels were captured by the National troops. On the 2d of October, General Rosecrans issued the following order, dated at the Headquarters of the Department of the Cumberland, at Chattanooga.
