Further from Kentucky.
Chattanooga, Oct. 20.
--The last we have from Bragg's army he was at London, Ky., falling back in order towards Cumberland Gap.
Buell has a very large army, and endeavored to flank Bragg while at Camp Dick Robinson, which was prevented by this retreat.
Buell is yet endeavoring to flank him and there may be a battle any day.
The report that our army took a large number of prisoners at Perryville, proves incorrect.
