Still following literally the instructions of General Halleck, I pushed forward the repairs of the railroad, and ordered General Blair, with the two leading divisions, to drive the enemy beyond Tuscumbia. This he did successfully, after a pretty severe fight at Cane Creek, occupying Tuscumbia on the 27th of October.

In the meantime many important changes in command had occurred, which I must note here, to a proper understanding of the case.

General Grant had been called from Vicksburg, and sent to Chattanooga to command the military division of the Mississippi, composed of the three Departments of the Ohio, Cumberland, and Tennessee; and the Department of the Tennessee had been devolved on me, with instructions, however, to retain command of the army in the field. At Iuka I made what appeared to me the best disposition of matters relating to the department, giving General McPherson full powers in Mississippi and General Hurlbut in West Tennessee, and assigned General Blair to the command of the Fifteenth Army Corps; and summoned General Hurlbut from Memphis, and General Dodge from Corinth, and selected out of the Sixteenth Corps a force of about eight thousand men, which I directed General Dodge to organize with all expedition, and with it to follow me eastward.

On the 27th of October, when General Blair, with two divisions, was at Tuscumbia, I ordered General Ewing, with the Fourth Division, to cross the Tennessee (by means of the gunboats and scow) as rapidly as possible at Eastport, and push forward to Florence, which he did; and the same day a messenger from General Grant floated down the Tennessee over Muscle Shoals, landed at Tuscumbia, and was sent to me at Iuka. He bore a short message from the general to this effect: "Drop all work on the railroad east of Bear Creek; push your command toward Bridgeport till you meet orders;" etc. Instantly the order was executed; the order of march was reversed, and all the columns were directed to Eastport, the only place where we could cross the Tennessee. At first we only had the gunboats and coal-barge; but the ferry-boat and two transports arrived on the 31st of October, and the work of crossing was pushed with all the vigor possible. In person I crossed, and passed to the head of the column at Florence on the 1st of November, leaving the rear divisions to be conducted by General Blair, and marched to Rogersville and Elk River. This was found impassable. To ferry would have consumed to much time, and to build a bridge still more; so there was no alternative but to turn up Elk River by way of Gilbertsboro, Elkton, etc., to the stone bridge at Fayetteville, where we crossed the Elk, and proceeded to Winchester and Deckerd.

At Fayetteville I received orders from General Grant to come to Bridgeport with the Fifteenth Army Corps, and to leave General Dodge's command at Pulaski, and along the railroad from Columbia to Decatur. I instructed General Blair to follow with the Second and First Divisions by way of New Market, Larkinsville, and Bellefonte, while I conducted the other two divisions by way of Deckerd; the Fourth Division crossing the mountain to Stevenson, and the Third by University Place and Sweden's Cove.

In person I proceeded by Sweden's Cove and Battle Creek, reaching Bridgeport on the night of November 13th. I immediately telegraphed to the commanding general my arrival, and the positions of my several divisions, and was summoned to Chattanooga. I took the first steamboat daring the night of the 14th for Belly's Ferry, and rode into Chattanooga on the 16th. I then learned the part assigned me in the coming drama, was supplied with the necessary maps and information, and rode, during the 18th, in company with Generals Grant, Thomas, W. F. Smith, Brannan, and others, to the positions occupied on the west bank of the Tennessee, from which could be seen the camps of the enemy, compassing Chattanooga and the line of Missionary Hills, with its terminus on Chickamauga Creek, the point that I was expected to take, hold, and fortify. Pontoons, with a full supply of balks and chesses, had been prepared for the bridge over the Tennessee, and all things had been prearranged with a foresight that elicited my admiration. From the hills we looked down on the amphitheatre of Chattanooga as on a map, and nothing remained but for me to put my troops in the desired position. The plan contemplated that, in addition to crossing the Tennessee River and making a lodgment on the terminus of Missionary Ridge, I should demonstrate against Lookout Mountain, near Trenton, with a part of my command.

All in Chattanooga were impatient for action, rendered almost acute by the natural apprehensions felt for the safety of General Burnside in East Tennessee.

My command had marched from Memphis, three hundred and thirty miles, and I had pushed them as fast as the roads and distance would admit, but I saw enough of the condition of men and animals in Chattanooga to inspire me with renewed energy. I immediately ordered my leading division (General Ewing's) to march via Shellmound to Trenton, demonstrating against Lookout Ridge, but to be prepared to turn quickly and follow me to Chattanooga and in person I returned to Bridgeport, rowing a boat down the Tennessee from Belly's Ferry, and immediately on arrival put in motion my divisions in the order in which they had arrived. The bridge of boats at Bridgeport was frail, and, though used day and night, our passage was slow; and the road thence to Chattanooga was dreadfully cut up and encumbered with the wagons of the other troops stationed along the road. I reached General Hooker's headquarters during a rain, in the afternoon of the 20th, and met General Grant's orders for the general attack on the next day. It was simply impossible for me to fulfill my part in time; only one division (General John E. Smith's) was in position. General Ewing was still at Trenton, and the other two were toiling along the terrible road from Shellmound to Chattanooga. No troops ever were or could be in better condition than mine, or who labored harder to fulfill their part. On a proper representation, General Grant postponed the attack. On the 21st I got the Second Division over Brown's-Ferry Bridge, and General Ewing got up; but the bridge broke repeatedly, and delays occurred which no human sagacity could prevent. All labored night and day, and General Ewing got over on the 23d; but my rear division was cut off by the broken bridge at Brown's Ferry, and could not join me. I offered to go into action with my three divisions, supported by General Jeff. C. Davis, leaving one of my best divisions (Osterhaus's) to act with General Hooker against Lookout Mountain. That division has not joined me yet, but I know and feel that it has served the country well, and that it has reflected honor on the Fifteenth Army Corps and the Army of the Tennessee. I leave the record of its history to General Hooker, or whomsoever has had its services during the late memorable events, confident that all will do it merited honor.

At last, on the 28d of November, my three divisions lay behind the hills opposite the mouth of the Chickamauga. I dispatched the brigade of the Second Division, commanded by General Giles A. Smith, under cover of the hills, to North Chickamauga Creek, to man the boats designed for the pontoon-bridge, with orders (at midnight) to drop down silently to a point above the mouth of the South Chickamauga, there land two regiments, who were to move along the river-bank quietly, and capture the enemy's river-pickets.

General Giles A. Smith then was to drop rapidly below the month of the Chickamauga, disembark the rest of his brigade, and dispatch the boats across for fresh loads. These orders were skillfully executed, and every rebel picket but one was captured. The balance of General Morgan L. Smith's division was then rapidly ferried across; that of General John E. Smith followed, and by daylight of November 24th two divisions of about eight thousand men were on the east bank of the Tennessee, and had thrown up a very respectable rifle-trench as a tete du pont. As soon as the day dawned, some of the boats were taken from the use of ferrying, and a pontoon-bridge was begun, under the immediate direction of Captain Dresser, the whole planned and supervised by General William F. Smith in person. A pontoon-bridge was also built at the same time over Chickamanga Creek, near its mouth, giving communication with the two regiments which had been left on the north side, and fulfilling a most important purpose at a later stage of the drama. I will here bear my willing testimony to the completeness of this whole business. All the officers charged with the work were present, and manifested a skill which I cannot praise too highly. I have never beheld any work done so quietly, so well; and I doubt if the history of war can show a bridge of that extent (viz., thirteen hundred and fifty feet) laid so noiselessly and well, in so short a time. I attribute it to the genius and intelligence of General William F. Smith. The steamer Dunbar arrived up in the course of the morning, and relieved Ewing's division of the labor of rowing across; but by noon the pontoon-bridge was done, and my three divisions were across, with men, horses, artillery, and every thing.
