Libby Prison was certainly not of palatial dimensions or accommodations. Before the war it had been a tobacco warehouse, situated close by the Lynchburg Canal, and a short distance from James River, whose waters ran by in full view of the longing eyes which gazed upon them from the close-barred prison windows. For the story which we have to tell some description of the make-up of this place of detention is a necessary preliminary. The building was three stories high in front, and four in the rear, its dimensions being one hundred and sixty-five by one hundred and five feet. It was strongly built, of brick and stone, while very thick partition walls of brick divided it internally into three sections. Each section had its cellar, one of them, with which we are particularly concerned, being unoccupied. The others were occasionally used. The first floor had three apartments, one used by the prison authorities, one as a hospital, while the middle one served the prisoners as a cooking-and dining-room. The second and third stories were the quarters of the prisoners, where, in seven rooms, more than eleven hundred United States officers ate, slept, and did all the duties of life for many months. It may even be said that they enjoyed some of the pleasures of life, for though the discipline was harsh and the food scanty and poor, man's love of enjoyment is not easily to be repressed, and what with occasional minstrel and theatrical entertainments among themselves, fencing exercises with wooden swords, games of cards, checkers and chess, study of languages, military tactics, etc., and other entertainments and pastimes, they managed somewhat to overcome the monotony of prison life and the hardship of prison discipline. As regards chances of escape, they were very poor. A strong guard constantly surrounded the prison, and such attempts at escape as were made were rarely successful. The only one that had measurable success is that which we have to describe, in which a body of prisoners played the r[^o]le of rats or beavers, and got out of Libby by an underground route. The tunnel enterprise was the project of a few choice spirits only. It was too perilous to confide to many. The disused cellar was chosen as the avenue of escape. It was never visited, and might be used with safety. But how to get there was a difficult question to solve. And how to hide the fact that men were absent from roll-call was another. The latter difficulty was got over by several expedients. If Lieutenant Jones, for instance, was at work in the tunnel, Captain Smith would answer for him; then, when Smith was pronounced absent, he would step forward and declare that he had answered to his own name. His presence served as sure proof that he had not been absent. Other and still more ingenious methods were at times adopted, and the authorities were completely hoodwinked in this particular.
