But all was not lost. General Thomas commanded the Union left. Like a flinty rock he stood while Polk’s and Longstreet’s troops surged in heavy masses against his front and flank. About three o’clock heavy columns were seen pouring through a gorge almost in Thomas’s rear. They were Longstreet’s men. It was a critical moment Granger’s reserves came rushing upon the field. Raw recruits though they were, they dashed against Longstreet like veterans. In twenty minutes, at cost of frightful slaughter, the gorge and ridge were theirs. Longstreet made another assault, but was again repulsed. At nightfall Thomas fell back to Chattanooga, henceforth named, and justly, the “Rock of Chickamauga.” For six hours he had held his own with 25,000 braves against twice that number. Out of 70,000 troops Bragg lost probably 20,000. Rosecrans’s force was about 55,000, his loss 16,000.
General George H. Thomas.
Bragg proceeded to shut up the Union army in Chattanooga. Grant, now commanding the Department of the Mississippi, was ordered to recover Chattanooga, and his deeds along this front, though less often mentioned, will glitter upon the page of history with little if any less lustre than those about Vicksburg. Upon his arrival, late in October, he found the city practically in a state of siege. Its railroad communication with Nashville was cut off, and supplies had to be hauled in wagons sixty miles over a rough mountain road. The men had been for some time on half rations. Thousands of horses and mules had starved, and the artillery could not be moved for lack of teams. There was not ammunition enough for one day’s fighting. In five days Grant wrested the railroad from Bragg’s men and bridged the Tennessee, so that an abundant supply of food and ammunition came pouring in.
Elated at his Chickamauga triumph, and unaware that he now had a greater than Rosecrans in his front, Bragg deemed it a safe and promising stratagem to despatch Longstreet’s corps to Knoxville to capture Burnside. It was a fatal step, and Grant was not slow to take advantage of it. He telegraphed Sherman to put his entire force instantly en route from Vicksburg to Chattanooga.
Chattanooga lies on the south side of the Tennessee River, at the northern end of a valley running north and south. Along the eastern edge of the valley rises Missionary Ridge. On the western side and farther south, stands Lookout Mountain. After passing Chattanooga, the river turns and runs south till it laves the base of Lookout Mountain. The Confederate fortifications, twelve miles in length, ran along Missionary Ridge, across the southern end of the valley, and up over Lookout Mountain.
On November 23d, Thomas, who had succeeded Rosecrans, stormed the breastworks half a mile from the base of Missionary Ridge. The next day Grant sent “Fighting Joe Hooker” to sweep Bragg’s detachment from Lookout Mountain. Mist lay along the lofty slopes as the gallant Hooker and his men moved up them, soon veiling the entire column from sight; and it was only by the rattle of the musketry that Grant knew how the fight progressed. This was the famous “Battle Above the Clouds.” Hooker pounded the enemy so lustily that they were glad to evacuate the mountain in the night, and the next morning the Stars and Stripes saluted the breezes of its topmost peak.
General Joseph Hooker.
While Hooker had been thus engaged, and for some days before, Sherman had been at a movement that was even more momentous. He had slyly thrust his army up the Tennessee River above the city, placing it between the river and Missionary Ridge, and had worked its flank to the left as far as the mouth of Chickamauga Creek. He had thus gotten possession of the entire northeastern spur of that ridge with hardly the loss of a corporal’s guard.
