THREE:The train started as Levi had ordered, and sped along on a clear track to Nashville. Cotton was needed at the North almost as much as rations were needed at the front, and a train loaded with Treasury cotton had superior rights to the track which must not be disregarded. At Nashville a friend of Levi's, a Surgeon of generally recognized skill, and whom Levi had telegraphed for, came aboard with a couple of skilled nurses, who bathed the boys, dressed their wounds, and replaced their soiled, torn clothes with new, clean ones, including fine, soft underwear from Levi's own wardrobe.He warmed some water, and tenderly as he could command his strong, stubby hands, washed Si's face, hands and feet, and combed his hair. The overworked hospital attendants had had no time for this much-needed ministration. It was all that they could do to get the wounded under some sort of shelter, to dress their wounds, and prepare food. No well man could be spared from the trenches for hospital service, for the sadly-diminished Army of the Cumberland needed every man who could carry a musket to man the long lines to repel the constantly-threatened assaults.
