The danger of discovery was continual, for the guards were under instructions from the prison commandant to make occasional visits to every accessible part of the building; so that it was not unusual for a sergeant and several men to enter the south door of Rat Hell in the daytime, while the diggers were at labor in the dark north end. During these visits the digger would watch the intruders with his head sticking out of the tunnel, while the others would crouch behind the low stone fenders, or crawl quickly under the straw. This was, however, so uninviting a place that the Confederates made this visit as brief as a nominal compliance with their orders permitted, and they did not often venture into the dark north end. The work was fearfully monotonous, and the more so because absolute silence was commanded, the men moving about mutely in the dark. The darkness caused them frequently to become bewildered and lost; and as Rose could not call out for them, he had often to hunt all over the big dungeon to gather them up and pilot them to their places.

The difficulty of forcing air to the digger, whose body nearly filled the tunnel, increased as the hole was extended, and compelled the operator to back often into the cellar for air, and for air that was itself foul enough to sicken a strong man.

But they were no longer harassed with the water and timbers that had impeded their progress at the south end. Moreover, experience was daily making each man more proficient in the work. Rose urged them on with cheery enthusiasm, and their hopes rose high, for already they had penetrated beyond the sentinel's beat and were nearing the goal.

The party off duty kept a cautious lookout from the upper east windows for any indications of suspicion on the part of the Confederates. In this extreme caution was necessary, both to avert the curiosity of prisoners in those east rooms, and to keep out of the range of bullets from the guards, who were under a standing order to fire at a head if seen at a window, or at a hand if placed on the bars that secured them. A sentinel's bullet one day cut a hole in the ear of Lieutenant Hammond; another officer was wounded in the face by a bullet, which fortunately first splintered against one of the window-bars; and a captain of an Ohio regiment was shot through the head and instantly killed while reading a newspaper. He was violating no rule whatever, and when shot was from eight to ten feet inside the window through which the bullet came. This was a wholly unprovoked and wanton murder; the cowardly miscreant had fired the shot while he was off duty, and from the north sidewalk of Carey street. The guards (home guards they were) used, in fact, to gun for prisoners' heads from their posts below, pretty much after the fashion of boys after squirrels; and the whizz of a bullet through the windows became too common an occurrence to occasion remark unless some one was shot.

Under a standing rule, the twelve hundred prisoners were counted twice each day, the first count being made about nine in the morning, and the last about four in the afternoon. This duty was habitually done by the clerk of the prison, E.W. Ross, a civilian employed by the commandant. He was christened "Little Ross"[13] by the prisoners, because of his diminutive size. Ross was generally attended by either "Dick" Turner, Adjutant Latouche, or Sergeant George Stansil, of the 18th Georgia, with a small guard to keep the prisoners in four closed ranks during the count. The commandant of the prison, Major Thomas P. Turner (no relative of Dick's), seldom came up-stairs.

[13] "Little Ross" was burned to death, with other guests, at the Spotswood House, Richmond, in 1873.

To conceal the absence of the five men who were daily at work at the tunnel, their comrades of the party off digging duty resorted, under Rose's supervision, to a device of "repeating." This scheme, which was of vital importance to hoodwink the Confederates and avert mischievous curiosity among the uninformed prisoners, was a hazardous business that severely taxed the ingenuity and strained the nerve of the leader and his coadjutors. The manner of the fraud varied with circumstances, but in general it was worked by five of Rose's men, after being counted at or near the head of the line, stooping down and running toward the foot of the ranks, where a few moments later they were counted a second time, thus making Ross's book balance. The whole five, however, could not always do this undiscovered, and perhaps but three of the number could repeat. These occasional mishaps threatened to dethrone the reason of the puzzled clerk; but in the next count the "repeaters" would succeed in their game, and for the time all went well, until one day some of the prisoners took it into their heads, "just for the fun of the thing," to imitate the repeaters. Unconscious of the curses that the party were mentally hurling at them, the meddlers' sole purpose was to make "Little Ross" mad. In this they certainly met with signal success, for the reason of the mystified clerk seemed to totter as he repeated the count over and over in the hope of finding out how one careful count would show that three prisoners were missing and the next an excess of fifteen. Finally Ross, lashed into uncontrollable fury by the sarcastic remarks of his employers and the heartless merriment of the grinning Yanks before him, poured forth his goaded soul as follows:

"Now, gentlemen, look yere. I can count a hundred as good as any blank man in this yere town, but I'll be blank blanked if I can count a hundred of you blanked Yankees. Now, gentlemen, there's one thing sho: there's eight or ten of you-uns yere that ain't yere!"

This extraordinary accusation "brought down the house," and the Confederate officers and guards, and finally Ross himself, were caught by the resistless contagion of laughter that shook the rafters of Libby.

The officials somehow found a balance that day on the books, and the danger was for this once over, to the infinite relief of Rose and his anxious comrades. But the Confederates appeared dissatisfied with something, and came up-stairs next morning with more officers and with double the usual number of guards; and some of these were now stationed about the room so as to make it next to impossible to work the repeating device successfully. On this day, for some reason, there were but two men in the cellar, and these were Major B.B. McDonald and Captain I.N. Johnson.
