As soon as Sherman discovered that the enemy had left his front he directed his reserves, Davis's division of the Army of the Cumberland, to push over the pontoon-bridge at the mouth of the Chickamauga, and to move forward to Chickamauga Station. He ordered Howard to move up the stream some two miles to where there was an old bridge, repair it during the night, and follow Davis at four o'clock in the morning. Morgan L. Smith was ordered to reconnoitre the tunnel to see if that was still held. Nothing was found there but dead bodies of men of both armies. The rest of Sherman's command was directed to follow Howard at daylight in the morning to get on to the railroad towards Graysville.
Hooker, as stated, was detained at Chattanooga Creek by the destruction of the bridge at that point. He got his troops over, with the exception of the artillery, by fording the stream at a little after three o'clock. Leaving his artillery to follow when the bridge should be reconstructed, he pushed on with the remainder of his command. At Rossville he came upon the flank of a division of the enemy, which soon commenced a retreat along the ridge. This threw them on Palmer. They could make but little resistance in the position they were caught in, and as many of them as could do so escaped. Many, however, were captured. Hooker's position during the night of the 25th was near Rossville, extending east of the ridge. Palmer was on his left, on the road to Graysville.
During the night I telegraphed to Willcox that Bragg had been defeated, and that immediate relief would be sent to Burnside if he could hold out; to Halleck I sent an announcement of our victory, and informed him that forces would be sent up the valley to relieve Burnside.
Before the battle of Chattanooga opened I had taken measures for the relief of Burnside the moment the way should be clear. Thomas was directed to have the little steamer that had been built at Chattanooga loaded to its capacity with rations and ammunition. Granger's corps was to move by the south bank of the Tennessee River to the mouth of the Holston, and up that to Knoxville accompanied by the boat. In addition to the supplies transported by boat, the men were to carry forty rounds of ammunition in their cartridge-boxes, and four days' rations in haversacks.
In the battle of Chattanooga, troops from the Army of the Potomac, from the Army of the Tennessee, and from the Army of the Cumberland participated. In fact, the accidents growing out of the heavy rains and the sudden rise in the Tennessee River so mingled the troops that the organizations were not kept together, under their respective commanders, during the battle. Hooker, on the right, had Geary's division of the 12th corps, Army of the Potomac; Osterhaus's division of the 15th corps, Army of the Tennessee; and Cruft's division of the Army of the Cumberland. Sherman had three divisions of his own army, Howard's corps from the Army of the Potomac, and Jefferson C. Davis's division of the Army of the Cumberland. There was no jealousy—hardly rivalry. Indeed, I doubt whether officers or men took any note at the time of the fact of this intermingling of commands. All saw a defiant foe surrounding them, and took it for granted that every move was intended to dislodge him, and it made no difference where the troops came from so that the end was accomplished.
The victory at Chattanooga was won against great odds, considering the advantage the enemy had of position, and was accomplished more easily than was expected by reason of Bragg's making several grave mistakes: first, in sending away his ablest corps commander with over twenty thousand troops; second, in sending away a division of troops on the eve of battle; third, in placing so much of a force on the plain in front of his impregnable position.
It was known that Mr. Jefferson Davis had visited Bragg on Missionary Ridge a short time before my reaching Chattanooga. It was reported and believed that he had come out to reconcile a serious difference between Bragg and Longstreet, and finding this difficult to do, planned the campaign against Knoxville, to be conducted by the latter general. I had known both Bragg and Longstreet before the war, the latter very well. We had been three years at West Point together, and, after my graduation, for a time in the same regiment. Then we served together in the Mexican War. I had known Bragg in Mexico, and met him occasionally subsequently. I could well understand how there might be an irreconcilable difference between them.
Bragg was a remarkably intelligent and well-informed man, professionally and otherwise. He was also thoroughly upright. But he was possessed of an irascible temper, and was naturally disputatious. A man of the highest moral character and the most correct habits, yet in the old army he was in frequent trouble. As a subordinate he was always on the lookout to catch his commanding officer infringing his prerogatives; as a post commander he was equally vigilant to detect the slightest neglect, even of the most trivial order.
I have heard in the old army an anecdote very characteristic of Bragg. On one occasion, when stationed at a post of several companies commanded by a field officer, he was himself commanding one of the companies and at the same time acting as post quartermaster and commissary. He was first lieutenant at the time, but his captain was detached on other duty. As commander of the company he made a requisition upon the quartermaster—himself—for something he wanted. As quartermaster he declined to fill the requisition, and endorsed on the back of it his reasons for so doing. As company commander he responded to this, urging that his requisition called for nothing but what he was entitled to, and that it was the duty of the quartermaster to fill it. As quartermaster he still persisted that he was right. In this condition of affairs Bragg referred the whole matter to the commanding officer of the post. The latter, when he saw the nature of the matter referred, exclaimed: "My God, Mr. Bragg, you have quarrelled with every officer in the army, and now you are quarrelling with yourself!"
Longstreet was an entirely different man. He was brave, honest, intelligent, a very capable soldier, subordinate to his superiors, just and kind to his subordinates, but jealous of his own rights, which he had the courage to maintain. He was never on the lookout to detect a slight, but saw one as soon as anybody when intentionally given.
