From the moment he realized that he was in the hands of the enemy, after the battle of New Baltimore, Glazier had made up his mind to exercise sleepless vigilance in seeking for opportunities of escape. He pondered over the matter until he became a complete enthusiast in his efforts to master the minute details of the construction and topography of the place of his confinement, and, by the exercise of that natural freemasonry which enables kindred spirits to recognize each other, soon effected an understanding upon the subject with certain of the more daring of his companions in misfortune. One of these gentlemen was a Lieutenant Tresouthick, an officer of the Eighteenth Pennsylvania Cavalry. In order to comprehend the plan which they finally determined to carry out, it will be necessary to premise that Libby Prison was a three-story structure, built over very ample cellarage; that the stories were each divided into three compartments, as was the cellar; and that these spaces were all of equal size in length and breadth. For the purpose of conveying a clear conception of the _locus in quo_ of the proposed effort, the reader should also be informed that the hospital occupied the first floor; that Lieutenant Tresouthick was one of the occupants of the room immediately above it; and that there were sinks built against the exterior wall of the same height as each story, and running the entire length of the building. The lieutenant's plan was, that "he should feign sickness and get into the hospital," says our hero, in describing the scheme; "and that I, in the meanwhile, should, with a saw-backed knife, cut a board out of the sink large enough to let us through." This looked feasible enough, and the two conspirators were beginning to felicitate themselves upon their approaching freedom, when they discovered that any such opening as they proposed, would let them out "directly opposite the guard," so _that_ plan had to be dropped. Glazier then proposed a plan of operations, promising better and safer results. It was, that Tresouthick should still carry out his original idea of a feigned sickness and consequent admission to the hospital; that he (Glazier) should procure a piece of rope, eight or ten feet long, and then, "some dark, rainy night," the pair should "steal down into the basement"--the outer doors of which were "not locked until ten o'clock"--and await their opportunity. That, when they once reached the exterior of the building, and the sentry's back was turned, they should rush past him on either side, and, with the rope, trip him up, in the hope of being beyond the reach of his musket before he could fire. This was approved by the lieutenant, and they made up their minds to try it. Of course, it was necessary that Lieutenant Tresouthick's illness should come on very gradually, and progress naturally from bad to worse, until he became a fit subject for the hospital, so that some time was occupied
