From General Bragg's Army.
[from our own Correspondent.]The enemy's movements yesterday were just sufficient to justify the suspicion that he intended to throw a force into McLemore's Cove to-day.--If such was his design he has abandoned it, for the present at least; but whether on account of the heavy rains last night and to day, or because he found that the vigilant eyes of the Confederates were upon him, it is impossible to say. That he has withdrawn his whole army out of Chattanooga except a few divisions, there can be but little doubt. The chief doubt felt is in regard to his designs, whether he intends to make an assault upon Lookout mountain, or to repeat the manœuvre of Rosecrans, and move down Wills's Valley in the direction of Rome, Ga. It is not supposed that the forces withdrawn have yet left the vicinity of Chattanooga; they are probably concealed in the timber on the north side of the river, or in Lookout Valley. Possibly a portion of them have marched up the river to the assistance of Burnside, now beleaguered in Knoxville. Thomas has declined to allow any further flags of truce for a week to come, and this of itself is significant of a desire for concealment.
The storm has certainly gathered, and the thunderbolt is forged and ready to be launched; but we hope that the movement in East Tennessee will serve as a conductor, and that if the lightning be not stayed altogether it may at least be diverted from our devoted heads.
Up to five o'clock this afternoon no intelligence had been received at headquarters of any engagement in the neighborhood of Knoxville other than that between Wheeler and the Federal cavalry, in which we captured about 300 prisoners, killed and wounded about 100, and drove the enemy from Maryville back into Knoxville. A dispatch has just been received from Gen. Longstreet, in which he states that Burnside had retired upon Knoxville, where he now has been surrounded. It was desired that Gen. Longstreet's connection with the expedition should not be made public for the present; but, since it has found its way into the newspapers, it need not be disguised that he is in command of our forces now operating in East Tennessee.
The letter published in the New York Herald, purporting to have been written by Col. Northrop, Commissary General of the Confederate States, to the Secretary of War, in relation to an apprehended scarcity of supplies, and detailing his interview with certain Southern Governors at Milledgeville and with Gen. Bragg at Dalton, is a transparent forgery. No such trip was ever made by Colonel Northrop, and Gen. Bragg never saw him or wrote to him on the subject. At the time spoken of, Gen. B. was at Tullahoma.
Persons visiting their friends in the army would do well to bring their blankets with them; for neither officers nor men have enough to share even with brothers and fathers. When the visit is completed, they might do another good thing, and that is, leave their blankets with their army friends.
The weather is clearing up as I write--10 o'clock at night, and there is a prospect of blue skies to-morrow. Sallust.
