THE RELIEF OF KNOXVILLE--HEADQUARTERS MOVED TO NASHVILLE--VISITING KNOXVILLE-CIPHER CIPHER DISPATCHES--WITHHOLDING ORDERS.
Chattanooga now being secure to the National troops beyond any doubt, I immediately turned my attention to relieving Knoxville, about the situation of which the President, in particular, was very anxious. Prior to the battles, I had made preparations for sending troops to the relief of Burnside at the very earliest moment after securing Chattanooga. We had there two little steamers which had been built and fitted up from the remains of old boats and put in condition to run. General Thomas was directed to have one of these boats loaded with rations and ammunition and move up the Tennessee River to the mouth of the Holston, keeping the boat all the time abreast of the troops.
General Granger, with the 4th corps reinforced to make twenty thousand men, was to start the moment Missionary Ridge was carried, and under no circumstances were the troops to return to their old camps. With the provisions carried, and the little that could be got in the country, it was supposed he could hold out until Longstreet was driven away, after which event East Tennessee would furnish abundance of food for Burnside's army and his own also.
While following the enemy on the 26th, and again on the morning of the 27th, part of the time by the road to Ringgold, I directed Thomas, verbally, not to start Granger until he received further orders from me; advising him that I was going to the front to more fully see the situation. I was not right sure but that Bragg's troops might be over their stampede by the time they reached Dalton. In that case Bragg might think it well to take the road back to Cleveland, move thence towards Knoxville, and, uniting with Longstreet, make a sudden dash upon Burnside.
When I arrived at Ringgold, however, on the 27th, I saw that the retreat was most earnest. The enemy had been throwing away guns, caissons and small-arms, abandoning provisions, and, altogether, seemed to be moving like a disorganized mob, with the exception of Cleburne's division, which was acting as rear-guard to cover the retreat.
When Hooker moved from Rossville toward Ringgold Palmer's division took the road to Graysville, and Sherman moved by the way of Chickamauga Station toward the same point. As soon as I saw the situation at Ringgold I sent a staff officer back to Chattanooga to advise Thomas of the condition of affairs, and direct him by my orders to start Granger at once. Feeling now that the troops were already on the march for the relief of Burnside I was in no hurry to get back, but stayed at Ringgold through the day to prepare for the return of our troops.
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.
