This ended the hopes of the fugitives. They had exhausted their means of checking pursuit. Their wood had been all consumed in this fruitless effort; their steam was rapidly going down; they had played their last card and lost the game. The men sprang from the slowed-up engine. The engineer reversed its valves and followed them. Into the fields they rushed and ran in all directions, their only hope being now in their own powers of flight. As they sped away the engines met, but without damage. The steam in the stolen engine had so fallen that it was incapable of doing harm. The other engine had been stopped, and the pursuers were springing agilely to the ground, and hurrying into the fields in hot chase. Pursuit through field and forest was as keen and unrelenting as it had been over iron rails. The Union lines were not far distant, yet not a man of the fugitives succeeded in reaching them. The alarm spread with great rapidity; the whole surrounding country was up in pursuit; and before that day ended several of the daring raiders were prisoners in Confederate hands. The others buried themselves in woods and swamps, lived on roots and berries, and ventured from their hiding-places only at night. Yet they were hunted with unwearying persistence, and by the end of a week all but two had been captured. These two had so successfully eluded pursuit that they fancied themselves out of danger, and became somewhat careless in consequence. As a result, in a few days more they, too, fell into the hands of their foes. A court-martial was convened. The attempt had been so daring, and so nearly successful, the injury intended so great, and the whole affair so threatening, that the Confederate military authorities could not think of leniency. Andrews and seven of his companions were condemned to death and hung. Their graves may be seen to-day in the Soldiers' Cemetery at Chattanooga, monuments to one of the most daring and reckless enterprises in the history of the Civil War. The others were imprisoned. AN ESCAPE FROM LIBBY PRISON. During the winter of 1864 certain highly interesting operations were going on in the underground region of the noted Libby Prison, at Richmond, Virginia, at that time the by no means luxurious or agreeable home of some eleven hundred officers of the United States army. These operations, by means of which numerous captives were to make their way to fresh air and freedom, are abundantly worthy of being told, as an evidence of the ingenuity of man and the amount of labor and hardship he is willing to give in exchange for liberty.
