The prisoners from Gettysburg.
--A letter dated Winchester, the 10th inst, says:‘ I crossed the river yesterday, on my way to report to a hospital in Winchester. At the same time two ferries were occupied crossing about five thousand Yankee prisoners. I passed the officers on the road to-day, (about 200) in charge of the remnant (250 men) of Garnett's brigade. Our division, or what is left of it, (Pickett's,) guard these prisoners.
