HDQRS. FOURTH DIVISION, FOURTEENTH ARMY CORPS, Trenton, Ga., September 9, 1863-9 a.m.

Lieutenant-Colonel FLYNT:

A paroled Vicksburg prisoner, named Baker, has this moment arrived from Atlanta, which place he left day before yesterday at 7 p.m. He has no furlough; lives 1 1/2 miles above this point. Says a great many Vicksburg prisoners are going home without furloughs, and that they are passed on the cars on their paroles. According to his information the only troops at Atlanta, when he came through, were recent conscripts, but on this point he is not definite. He left the cars at Tunnel Hill. Says he met what he supposed to be eight rebel regiments yesterday - at least they had eight colors - marching toward La Fayette from Chattanooga. Had no opportunity of conversing with rebel soldiers. Conversed with citizens in their rear, who say that Chattanooga is evacuated and "You'uns in possession." He has been sent to department headquarters.

Very respectfully,
J. J. REYNOLDS,

Major-General, Commanding Division.

Colonel Atkins, with Ninety-second Illinois (mounted), 400 strong, left on reconnaissance toward Chattanooga at daybreak this morning.
