Ringgold is in a valley in the mountains, situated between East Chickamauga Creek and Taylor's Ridge, and about twenty miles south-east from Chattanooga. I arrived just as the artillery that Hooker had left behind at Chattanooga Creek got up. His men were attacking Cleburne's division, which had taken a strong position in the adjacent hills so as to cover the retreat of the Confederate army through a narrow gorge which presents itself at that point. Just beyond the gorge the valley is narrow, and the creek so tortuous that it has to be crossed a great many times in the course of the first mile. This attack was unfortunate, and cost us some men unnecessarily. Hooker captured, however, 3 pieces of artillery and 230 prisoners, and 130 rebel dead were left upon the field.
I directed General Hooker to collect the flour and wheat in the neighboring mills for the use of the troops, and then to destroy the mills and all other property that could be of use to the enemy, but not to make any wanton destruction.
At this point Sherman came up, having reached Graysville with his troops, where he found Palmer had preceded him. Palmer had picked up many prisoners and much abandoned property on the route. I went back in the evening to Graysville with Sherman, remained there over night and did not return to Chattanooga until the following night, the 29th. I then found that Thomas had not yet started Granger, thus having lost a full day which I deemed of so much importance in determining the fate of Knoxville. Thomas and Granger were aware that on the 23d of the month Burnside had telegraphed that his supplies would last for ten or twelve days and during that time he could hold out against Longstreet, but if not relieved within the time indicated he would be obliged to surrender or attempt to retreat. To effect a retreat would have been an impossibility. He was already very low in ammunition, and with an army pursuing he would not have been able to gather supplies.
Finding that Granger had not only not started but was very reluctant to go, he having decided for himself that it was a very bad move to make, I sent word to General Sherman of the situation and directed him to march to the relief of Knoxville. I also gave him the problem that we had to solve—that Burnside had now but four to six days supplies left, and that he must be relieved within that time.
Sherman, fortunately, had not started on his return from Graysville, having sent out detachments on the railroad which runs from Dalton to Cleveland and Knoxville to thoroughly destroy that road, and these troops had not yet returned to camp. I was very loath to send Sherman, because his men needed rest after their long march from Memphis and hard fighting at Chattanooga. But I had become satisfied that Burnside would not be rescued if his relief depended upon General Granger's movements.
Sherman had left his camp on the north side of the Tennessee River, near Chattanooga, on the night of the 23d, the men having two days' cooked rations in their haversacks. Expecting to be back in their tents by that time and to be engaged in battle while out, they took with them neither overcoats nor blankets. The weather was already cold, and at night they must have suffered more or less. The two days' rations had already lasted them five days; and they were now to go through a country which had been run over so much by Confederate troops that there was but little probability of finding much food. They did, however, succeed in capturing some flour. They also found a good deal of bran in some of the mills, which the men made up into bread; and in this and other ways they eked out an existence until they could reach Knoxville.
I was so very anxious that Burnside should get news of the steps being taken for his relief, and thus induce him to hold out a little longer if it became necessary, that I determined to send a message to him. I therefore sent a member of my staff, Colonel J. H. Wilson, to get into Knoxville if he could report to Burnside the situation fully, and give him all the encouragement possible. Mr. Charles A. Dana was at Chattanooga during the battle, and had been there even before I assumed command. Mr. Dana volunteered to accompany Colonel Wilson, and did accompany him. I put the information of what was being done for the relief of Knoxville into writing, and directed that in some way or other it must be secretly managed so as to have a copy of this fall into the hands of General Longstreet. They made the trip safely; General Longstreet did learn of Sherman's coming in advance of his reaching there, and Burnside was prepared to hold out even for a longer time if it had been necessary.
Burnside had stretched a boom across the Holston River to catch scows and flats as they floated down. On these, by previous arrangements with the loyal people of East Tennessee, were placed flour and corn, with forage and provisions generally, and were thus secured for the use of the Union troops. They also drove cattle into Knoxville by the east side, which was not covered by the enemy; so that when relief arrived Burnside had more provisions on hand than when he had last reported.
Our total loss (not including Burnside's) in all these engagements amounted to 757 killed, 4,529 wounded and 330 missing. We captured 6,142 prisoners—about 50 per cent. more than the enemy reported for their total loss—40 pieces of artillery, 69 artillery carriages and caissons and over 7,000 stands of small-arms. The enemy's loss in arms was probably much greater than here reported, because we picked up a great many that were found abandoned.
I had at Chattanooga, in round numbers, about 60,000 men. Bragg had about half this number, but his position was supposed to be impregnable. It was his own fault that he did not have more men present. He had sent Longstreet away with his corps swelled by reinforcements up to over twenty thousand men, thus reducing his own force more than one-third and depriving himself of the presence of the ablest general of his command. He did this, too, after our troops had opened a line of communication by way of Brown's and Kelly's ferries with Bridgeport, thus securing full rations and supplies of every kind; and also when he knew reinforcements were coming to me. Knoxville was of no earthly use to him while Chattanooga was in our hands. If he should capture Chattanooga, Knoxville with its garrison would have fallen into his hands without a struggle. I have never been able to see the wisdom of this move.
