General Hooker and Staff at Lookout Mountain. Hooker's forces of about 9,700 men had been sent from the East to reënforce Rosecrans, but until the arrival of Grant they were simply so many more mouths to feed in the besieged city. In the battle of Wauhatchie, on the night of October 20th, they drove back the Confederates and established the new line of communication. On November 24th they, too, had a surprise in store for Grant. Their part in the triple conflict was also ordered merely as a "demonstration," but they astounded the eyes and ears of their comrades with the spectacular fight by which they made their way up Lookout Mountain. The next day, pushing on to Rossville, the daring Hooker attacked one of Bragg's divisions and forced it into precipitate retreat.

Up such rugged heights as these, heavily timbered and full of chasms, Hooker's men fought their way on the afternoon of November 24th. Bridging Lookout Creek, the troops crossed, hidden by the friendly mist, and began ascending the mountain-sides, driving the Confederates from one line of rifle-pits and then from another. The heavy musketry fire and the boom of the Confederate battery on the top of the mountain apprised the waiting Federals before Chattanooga that the battle had begun. Now and again the fitful lifting of the mist disclosed to Grant and Thomas, watching from Orchard Knob, the men of Hooker fighting upon the heights. Then all would be curtained once more. At two o'clock in the afternoon the mist became so heavy that Hooker and his men could not see what they were doing, and paused to entrench. By four o'clock, however, he had pushed on to the summit and reported to Grant that his position was impregnable. Direct communication was then established and reënforcements sent.

Before dawn of November 25th, Hooker, anticipating the withdrawal of the Confederates, sent detachments to seize the very summit of the mountain, here 2,400 feet high. Six volunteers from the Eighth Kentucky Regiment scaled the palisades by means of the ladders seen in this picture, and made their way to the top. The rest of the regiment quickly followed; then came the Ninety-sixth Illinois. The rays of the rising sun disclosed the Stars and Stripes floating in triumph from the lofty peak "amid the wild and prolonged cheers of the men whose dauntless valor had borne them to that point."
