"I think it very important for General Rosecrans to hold his position at or about Chattanooga, because, if held, from that place to Cleveland, both inclusive, it keeps all Tennessee clear of the enemy, and also breaks one of his most important railroad lines. If he can only maintain this position, without more, this rebellion can only eke out a short and feeble existence, as an animal sometimes may with a thorn in its vitals.

And to Rosecrans he telegraphed directly, bidding him be of good cheer, and adding: "We shall do our utmost to assist you." To this end the administration took instant and energetic measures. On the night of September 23, the President, General Halleck, several members of the cabinet, and leading army and railroad officials met in an improvised council at the War Department, and issued emergency orders under which two army corps from the Army of the Potomac, numbering twenty thousand men in all, with their arms and equipments ready for the field, the whole under command of General Hooker, were transported from their camps on the Rapidan by railway to Nashville and the Tennessee River in the next eight days. Burnside, who had arrived at Knoxville early in September, was urged by repeated messages to join Rosecrans, and other reinforcements were already on the way from Memphis and Vicksburg.

All this help, however, was not instantly available. Before it could arrive Rosecrans felt obliged to draw together within the fortifications of Chattanooga, while Bragg quickly closed about him, and, by practically blockading Rosecrans's river communication, placed him in a state of siege. In a few weeks the limited supplies brought the Union army face to face with famine. It having become evident that Rosecrans was incapable of extricating it from its peril, he was re

lieved and the command given to Thomas, while the three western departments were consolidated under General Grant, and he was ordered personally to proceed to Chattanooga, which place he reached on October 22.

Before his arrival, General W. F. Smith had devised and prepared an ingenious plan to regain control of river communication. Under the orders of Grant, Smith successfully executed it, and full rations soon restored vigor and confidence to the Union troops. The considerable reinforcements under Hooker and Sherman coming up, put the besieging enemy on the defensive, and active preparations were begun, which resulted in the famous battle and overwhelming Union victory of Chattanooga on November 23, 24, and 25, 1863.

The city of Chattanooga lies on the southeastern bank of the Tennessee River. Back of the city, Chattanooga valley forms a level plain about two miles in width to Missionary Ridge, a narrow mountain range five hundred feet high, generally parallel to the course of the Tennessee, extending far to the southwest. The Confederates had fortified the upper end of Missionary Ridge to a length of five to seven miles opposite the city, lining its long crest with about thirty guns, amply supported by infantry. This formidable barrier was still further strengthened by two lines of rifle-pits, one at the base of Missionary Ridge next to the city, and another with advanced pickets still nearer Chattanooga. Northward, the enemy strongly held the end of Missionary Ridge where the railroad tunnel passes through it; southward, they held the yet stronger point of Lookout Mountain, whose rocky base turns the course of the Tennessee River in a short bend to the north.

Grant's plan in rough outline was, that Sherman, with the Army of the Tennessee, should storm the northern end of Missionary Ridge at the railroad tunnel; Hooker, stationed at Wauhatchie, thirteen miles to the southwest with his two corps from the Army of the Potomac, should advance toward the city, storming the point of Lookout Mountain on his way; and Thomas, in the city, attack the direct front of Missionary Ridge. The actual beginning slightly varied this program, with a change of corps and divisions, but the detail is not worth noting.

Beginning on the night of November 23, Sherman crossed his command over the Tennessee, and on the afternoon of the twenty-fourth gained the northern end of Missionary Ridge, driving the enemy before him as far as the railroad tunnel. Here, however, he found a deep gap in the ridge, previously unknown to him, which barred his further progress. That same afternoon Hooker's troops worked their way through mist and fog up the rugged sides of Lookout Mountain, winning the brilliant success which has become famous as the "battle above the clouds." That same afternoon, also, two divisions of the center, under the eyes of Grant and Thomas, pushed forward the Union line about a mile, seizing and fortifying a hill called Orchard Knob, capturing Bragg's first line of rifle-pits and several hundred prisoners.

So far, everything had occurred to inspirit the Union troops and discourage the enemy. But the main incident was yet to come, on the afternoon of November 25. All the forenoon of that day Grant waited eagerly to see Sherman making progress along the north end of Missionary Ridge, not knowing that he had met an impassable valley. Grant's patience was equally tried at hearing no news from Hooker, though that

general had successfully reached Missionary Ridge, and was ascending the gap near Rossville.

At three o'clock in the afternoon Grant at length gave Thomas the order to advance. Eleven Union brigades rushed forward with orders to take the enemy's rifle-pits at the base of Missionary Ridge, and then halt to re-form. But such was the ease of this first capture, such the eagerness of the men who had been waiting all day for the moment of action, that, after but a slight pause, without orders, and moved by a common impulse, they swept on and up the steep and rocky face of Missionary Ridge, heedless of the enemy's fire from rifle and cannon at the top, until in fifty-five minutes after leaving their positions they almost simultaneously broke over the crest of the ridge in six different places, capturing the batteries and making prisoners of the supporting infantry, who, surprised and bewildered by the daring escalade, made little or no further resistance. Bragg's official report soundly berates the conduct of his men, apparently forgetting the heavy loss they had inflicted on their assailants, but regardless of which the Union veterans. mounted to victory in an almost miraculous exaltation of patriotic heroism.

Bragg's Confederate army was not only beaten, but hopelessly demoralized by the fiery Union assault, and fled in panic and retreat. Grant kept up a vigorous pursuit to a distance of twenty miles, which he ceased in order to send an immediate strong reinforcement under Sherman to relieve Burnside, besieged by the Confederate General Longstreet at Knoxville. But before this help arrived, Burnside had repulsed Longstreet, who, promptly informed of the Chattanooga disaster, retreated in the direction of Virginia. Not being pursued, however, this general again wintered

in East Tennessee; and for the same reason, the beaten army of Bragg halted in its retreat from Missionary Ridge at Dalton, where it also went into winter quarters. The battle of Chattanooga had opened the great central gateway to the south, but the rebel army, still determined and formidable, yet lay in its path, only twenty-eight miles away.
