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.
It may be that Longstreet was not sent to Knoxville for the reason stated, but because Mr. Davis had an exalted opinion of his own military genius, and thought he saw a chance of "killing two birds with one stone." On several occasions during the war he came to the relief of the Union army by means of his SUPERIOR MILITARY GENIUS.
I speak advisedly when I saw Mr. Davis prided himself on his military capacity. He says so himself, virtually, in his answer to the notice of his nomination to the Confederate presidency.
Some of his generals have said so in their writings since the downfall of the Confederacy.
My recollection is that my first orders for the battle of Chattanooga were as fought. Sherman was to get on Missionary Ridge, as he did; Hooker to cross the north end of Lookout Mountain, as he did, sweep across Chattanooga Valley and get across the south end of the ridge near Rossville. When Hooker had secured that position the Army of the Cumberland was to assault in the centre. Before Sherman arrived, however, the order was so changed as that Hooker was directed to come to Chattanooga by the north bank of the Tennessee River. The waters in the river, owing to heavy rains, rose so fast that the bridge at Brown's Ferry could not be maintained in a condition to be used in crossing troops upon it. For this reason Hooker's orders were changed by telegraph back to what they were originally.
