A train of wagons and men wound slowly over the hills in the darkness and rain toward the South. In the wagons lay fourteen or fifteen thousand wounded soldiers, but they made little noise, as the wheels sank suddenly in the mud or bumped over stones. Although the vast majority of them were young, boys or not much more, they had learned to be masters of themselves, and they suffered in silence, save when some one, lost in fever, uttered a groan.
