I take it for granted that Bragg's entire force has left. If not, of course, the first thing is to dispose of him. If he has gone, the only thing necessary to do to-morrow will be to send out a reconnoissance to ascertain the whereabouts of the enemy. Yours truly,

U. S. GRANT, Major-General.

P. S.-On reflection, I think we will push Bragg with all our strength to-morrow, and try if we cannot out off a good portion of his rear troops and trains. His men have manifested a strong disposition to desert for some time past, and we will now give them a chance. I will instruct Thomas accordingly. Move the advance force early, on the most easterly road taken by the enemy. U. S. G.

This compelled me to reverse our column, so as to use the bridge across the Chickamauga at its mouth. The next day we struck the rebel rear at Chickamauga Station, and again near Graysville. There we came in contact with Hooker's and Palmer's troops, who had reached Ringgold. There I detached Howard to cross Taylor's Ridge, and strike the railroad which comes from the north by Cleveland to Dalton. Hooker's troops were roughly handled at Ringgold, and the pursuit was checked. Receiving a note from General Hooker, asking help, I rode forward to Ringgold to explain the movement of Howard; where I met General Grant, and learned that the rebels had again retreated toward Dalton. He gave orders to discontinue the pursuit, as he meant to turn his attention to General Burnside, supposed to be in great danger at Knoxville, about one hundred and thirty miles northeast. General Grant returned and spent part of the night with me, at Graysville. We talked over matters generally, and he explained that he had ordered General Gordon Granger, with the Fourth Corps, to move forward rapidly to Burnsides help, and that he must return to Chattanooga to push him. By reason of the scarcity of food, especially of forage, he consented that, instead of going back, I might keep out in the country; for in motion I could pick up some forage and food, especially on the Hiawassee River, whereas none remained in Chattanooga.

Accordingly, on the 29th of November, my several columns marched to Cleveland, and the next day we reached the Hiawassee at Charleston, where the Chattanooga & Knoxville Railroad crosses it. The railroad-bridge was partially damaged by the enemy in retreating, but we found some abandoned stores. There and thereabouts I expected some rest for my weary troops and horses; but, as I rode into town, I met Colonel J. H. Wilson and C. A. Dana (Assistant Secretary of War), who had ridden out from Chattanooga to find me, with the following letter from General Grant, and copies of several dispatches from General Burnside, the last which had been received from him by way of Cumberland Gap:

HEADQUARTERS MILITARY DIVISION OF THE MISSISSIPPI, CHATTANOOGA,
TENNESSEE, Nov. 29, 1863

Major-General W. T. SHERMAN

News are received from Knoxville to the morning of the 27th. At that time the place was still invested, but the attack on it was not vigorous. Longstreet evidently determined to starve the garrison out. Granger is on the way to Burnside's relief, but I have lost all faith in his energy or capacity to manage an expedition of the importance of this one. I am inclined to think, therefore, I shall have to send you. Push as rapidly as you can to the Hiawassee, and determine for yourself what force to take with you from that point. Granger has his corps with him, from which you will select in conjunction with the force now with you. In plain words, you will assume command of all the forces now moving up the Tennessee, including the garrison at Kingston, and from that force, organize what you deem proper to relieve Burnside. The balance send back to Chattanooga. Granger has a boat loaded with provisions, which you can issue, and return the boat. I will have another loaded, to follow you. Use, of course, as sparingly as possible from the rations taken with you, and subsist off the country all you can.

It is expected that Foster is moving, by this time, from Cumberland Gap on Knoxville. I do not know what force he will have with him, but presume it will range from three thousand five hundred to five thousand I leave this matter to you, knowing that you will do better acting upon your discretion than you could trammeled with instructions. I will only add, that the last advices from Burnside himself indicated his ability to hold out with rations only to about the 3d of December. Very respectfully,

U. S. GRANT, Major-General commanding,
