That night [Oct. 24] I issued orders for opening the route to Bridgeport—a cracker line, as the soldiers appropriately termed it. They had been so long on short rations that my first thought was the establishment of a line over which food might reach them.
Chattanooga is on the south bank of the Tennessee, where that river runs nearly due west. It is at the northern end of a valley five or six miles in width, through which Chattanooga Creek runs. To the east of the valley is Missionary Ridge, rising from five to eight hundred feet above the creek and terminating somewhat abruptly a half mile or more before reaching the Tennessee. On the west of the valley is Lookout Mountain, twenty-two hundred feet above-tide water. Just below the town the Tennessee makes a turn to the south and runs to the base of Lookout Mountain, leaving no level ground between the mountain and river. The Memphis and Charleston Railroad passes this point, where the mountain stands nearly perpendicular. East of Missionary Ridge flows the South Chickamauga River; west of Lookout Mountain is Lookout Creek; and west of that, Raccoon Mountains. Lookout Mountain, at its northern end, rises almost perpendicularly for some distance, then breaks off in a gentle slope of cultivated fields to near the summit, where it ends in a palisade thirty or more feet in height. On the gently sloping ground, between the upper and lower palisades, there is a single farmhouse, which is reached by a wagon-road from the valley east.
The intrenched line of the enemy commenced on the north end of Missionary Ridge and extended along the crest for some distance south, thence across Chattanooga valley to Lookout Mountain. Lookout Mountain was also fortified and held by the enemy, who also kept troops in Lookout valley west, and on Raccoon Mountain, with pickets extending down the river so as to command the road on the north bank and render it useless to us. In addition to this there was an intrenched line in Chattanooga valley extending from the river east of the town to Lookout Mountain, to make the investment complete. Besides the fortifications on Mission Ridge, there was a line at the base of the hill, with occasional spurs of rifle-pits half-way up the front. The enemy’s pickets extended out into the valley towards the town, so far that the pickets of the two armies could converse. At one point they were separated only by the narrow creek which gives its name to the valley and town, and from which both sides drew water. The Union lines were shorter than those of the enemy.
Thus the enemy, with a vastly superior force, was strongly fortified to the east, south, and west, and commanded the river below. Practically, the Army of the Cumberland was besieged. The enemy had stopped with his cavalry north of the river the passing of a train loaded with ammunition and medical supplies. The Union army was short of both, not having ammunition enough for a day’s fighting.
General Halleck had, long before my coming into this new field, ordered parts of the 11th and 12th corps, commanded respectively by Generals Howard and Slocum, Hooker in command of the whole, from the Army of the Potomac to reinforce Rosecrans. It would have been folly to send them to Chattanooga to help eat up the few rations left there. They were consequently left on the railroad, where supplies could be brought to them. Before my arrival, Thomas ordered their concentration at Bridgeport.
General W. F. Smith had been so instrumental in preparing for the move which I was now about to make, and so clear in his judgment about the manner of making it, that I deemed it but just to him that he should have command of the troops detailed to execute the design, although he was then acting as a staff officer and was not in command of troops.
On the 24th of October, after my return to Chattanooga, the following details were made: General Hooker, who was now at Bridgeport, was ordered to cross to the south side of the Tennessee and march up by Whitesides and Wauhatchie to Brown’s Ferry. General Palmer, with a division of the 14th corps, Army of the Cumberland, was ordered to move down the river on the north side, by a back road, until opposite Whitesides, then cross and hold the road in Hooker’s rear after he had passed. Four thousand men were at the same time detailed to act under General Smith directly from Chattanooga. Eighteen hundred of them, under General Hazen, were to take sixty pontoon boats, and under cover of night float by the pickets of the enemy at the north base of Lookout, down to Brown’s Ferry, then land on the south side and capture or drive away the pickets at that point. Smith was to march with the remainder of the detail, also under cover of night, by the north bank of the river to Brown’s Ferry, taking with him all the material for laying the bridge as soon as the crossing was secured.
On the 26th, Hooker crossed the river at Bridgeport and commenced his eastward march. At three o’clock on the morning of the 27th, Hazen moved into the stream with his sixty pontoons and eighteen hundred brave and well-equipped men. Smith started enough in advance to be near the river when Hazen should arrive. There are a number of detached spurs of hills north of the river at Chattanooga, back of which is a good road parallel to the stream, sheltered from the view from the top of Lookout. It was over this road Smith marched. At five o’clock Hazen landed at Brown’s Ferry, surprised the picket guard, and captured most of it. By seven o’clock the whole of Smith’s force was ferried over and in possession of a height commanding the ferry. This was speedily fortified, while a detail was laying the pontoon bridge. By ten o’clock the bridge was laid, and our extreme right, now in Lookout valley, was fortified and connected with the rest of the army. The two bridges over the Tennessee River—a flying one at Chattanooga and the new one at Brown’s Ferry—with the road north of the river, covered from both the fire and the view of the enemy, made the connection complete.
I immediately reported the good news to Gen. Halleck,
CHATTANOOGA, October 28, 1863-8 p.m.
Maj. General H. W. HALLECK,
Washington, D. C.:
General Thomas’ plan for securing the river and south side road hence to Bridgeport has proven eminently successful. The question of supplies may now be regarded as settled. If the rebels give us one week more time I think all danger of losing territory now held by us will have passed away, and preparations may commence for offensive operations.
U. S. GRANT,
Major-General.
