Sherman had left Bridgeport the night of the 14th, reached Chattanooga the evening of the 15th, made the above-described inspection on the morning of the 16th, and started back the same evening to hurry up his command, fully appreciating the importance of time.

His march was conducted with as much expedition as the roads and season would admit of. By the 20th he was himself at Brown's Ferry with the head of column, but many of his troops were far behind, and one division (Ewing's) was at Trenton, sent that way to create the impression that Lookout was to be taken from the south. Sherman received his orders at the ferry, and was asked if he could not be ready for the assault the following morning. News had been received that the battle had been commenced at Knoxville. Burnside had been cut off from telegraphic communications. The President, the Secretary of War, and General Halleck, were in an agony of suspense. My suspense was also great, but more endurable, because I was where I could soon do something to relieve the situation. It was impossible to get Sherman's troops up for the next day. I then asked him if they could not be got up to make the assault on the morning of the 22d, and ordered Thomas to move on that date. But the elements were against us. It rained all the 20th and 21st. The river rose so rapidly that it was difficult to keep the pontoons in place.

General Orlando B. Willcox, a division commander under Burnside, was at this time occupying a position farther up the valley than Knoxville —about Maynardville—and was still in telegraphic communication with the North. A dispatch was received from him saying that he was threatened from the east. The following was sent in reply:

"If you can communicate with General Burnside, say to him that our attack on Bragg will commence in the morning. If successful, such a move will be made as I think will relieve East Tennessee, if he can hold out. Longstreet passing through our lines to Kentucky need not cause alarm. He would find the country so bare that he would lose his transportation and artillery before reaching Kentucky, and would meet such a force before he got through, that he could not return."

Meantime, Sherman continued his crossing without intermission as fast as his troops could be got up. The crossing had to be effected in full view of the enemy on the top of Lookout Mountain. Once over, however, the troops soon disappeared behind the detached hill on the north side, and would not come to view again, either to watchmen on Lookout Mountain or Missionary Ridge, until they emerged between the hills to strike the bank of the river. But when Sherman's advance reached a point opposite the town of Chattanooga, Howard, who, it will be remembered, had been concealed behind the hills on the north side, took up his line of march to join the troops on the south side. His crossing was in full view both from Missionary Ridge and the top of Lookout, and the enemy of course supposed these troops to be Sherman's. This enabled Sherman to get to his assigned position without discovery.

CHAPTER XLIII.

PREPARATIONS FOR BATTLE—THOMAS CARRIES THE FIRST LINE OF THE ENEMY —SHERMAN CARRIES MISSIONARY RIDGE—BATTLE OF LOOKOUT MOUNTAIN —GENERAL HOOKER'S FIGHT.

On the 20th, when so much was occurring to discourage—rains falling so heavily as to delay the passage of troops over the river at Brown's Ferry and threatening the entire breaking of the bridge; news coming of a battle raging at Knoxville; of Willcox being threatened by a force from the east—a letter was received from Bragg which contained these words: "As there may still be some non-combatants in Chattanooga, I deem it proper to notify you that prudence would dictate their early withdrawal." Of course, I understood that this was a device intended to deceive; but I did not know what the intended deception was. On the 22d, however, a deserter came in who informed me that Bragg was leaving our front, and on that day Buckner's division was sent to reinforce Longstreet at Knoxville, and another division started to follow but was recalled. The object of Bragg's letter, no doubt, was in some way to detain me until Knoxville could be captured, and his troops there be returned to Chattanooga.

During the night of the 21st the rest of the pontoon boats, completed, one hundred and sixteen in all, were carried up to and placed in North Chickamauga. The material for the roadway over these was deposited out of view of the enemy within a few hundred yards of the bank of the Tennessee, where the north end of the bridge was to rest.

Hearing nothing from Burnside, and hearing much of the distress in
Washington on his account, I could no longer defer operations for his
relief. I determined, therefore, to do on the 23d, with the Army of the
Cumberland, what had been intended to be done on the 24th.

The position occupied by the Army of the Cumberland had been made very strong for defence during the months it had been besieged. The line was about a mile from the town, and extended from Citico Creek, a small stream running near the base of Missionary Ridge and emptying into the Tennessee about two miles below the mouth of the South Chickamauga, on the left, to Chattanooga Creek on the right. All commanding points on the line were well fortified and well equipped with artillery. The important elevations within the line had all been carefully fortified and supplied with a proper armament. Among the elevations so fortified was one to the east of the town, named Fort Wood. It owed its importance chiefly to the fact that it lay between the town and Missionary Ridge, where most of the strength of the enemy was. Fort Wood had in it twenty-two pieces of artillery, most of which would reach the nearer points of the enemy's line. On the morning of the 23d Thomas, according to instructions, moved Granger's corps of two divisions, Sheridan and T. J. Wood commanding, to the foot of Fort Wood, and formed them into line as if going on parade, Sheridan on the right, Wood to the left, extending to or near Citico Creek. Palmer, commanding the 14th corps, held that part of our line facing south and southwest. He supported Sheridan with one division (Baird's), while his other division under Johnson remained in the trenches, under arms, ready to be moved to any point. Howard's corps was moved in rear of the centre. The picket lines were within a few hundred yards of each other. At two o'clock in the afternoon all were ready to advance. By this time the clouds had lifted so that the enemy could see from his elevated position all that was going on. The signal for advance was given by a booming of cannon from Fort Wood and other points on the line. The rebel pickets were soon driven back upon the main guards, which occupied minor and detached heights between the main ridge and our lines. These too were carried before halting, and before the enemy had time to reinforce their advance guards. But it was not without loss on both sides. This movement secured to us a line fully a mile in advance of the one we occupied in the morning, and the one which the enemy had occupied up to this time. The fortifications were rapidly turned to face the other way. During the following night they were made strong. We lost in this preliminary action about eleven hundred killed and wounded, while the enemy probably lost quite as heavily, including the prisoners that were captured. With the exception of the firing of artillery, kept up from Missionary Ridge and Fort Wood until night closed in, this ended the fighting for the first day.

The advantage was greatly on our side now, and if I could only have been assured that Burnside could hold out ten days longer I should have rested more easily. But we were doing the best we could for him and the cause.

By the
