From Fredericksburg.
The train last night brought us no interesting news from the army around Fredericksburg. Maticks remained in a state of quiet.By way of Gordonsvillis we have a report of a dash of Gen. Stuart upon a Yankee encampment in the vicinity of Dumfries, which resulted in the capture of nearly two hundred prisoners, a train of wagons, and a large supply of commissary and stores. Further particulars of the affair we were unable to learn.
