October 13th. The long roll called us up very early, before daylight. We turned out on double-quick time leaving camp on the run, out on the Winchester Pike. When out a short distance came to a halt. After waiting a while, was ordered to return to camp. Wondering what it meant. Later in the day we heard that Mosby and his guerillas captured a train on the B. & O. R. R. between Martinsburg and Harper’s Ferry. The train was badly damaged, passengers robbed. Mosby knows every road and path in this section.
