Calhoun now waited in feverish excitement for the success of the plan. He had done all he could. The rest depended on the prisoners themselves. Through the shrewdness and indomitable energy of Captain Thomas H. Hines the work was carried to a successful termination inside the prison wall. General Morgan occupied a cell in the second tier, and could do nothing. Only those who occupied cells on the ground floor had any hopes of escaping. Captain Hines, with infinite labor made an opening through the floor of his cell into the air chamber. Once in the air chamber they could work without being discovered. With only the table-knives to work with, these men went through two solid walls, one five feet, and the other six feet in thickness. Not only that, but they went through eleven feet of grouting. Then, working from under, they went through the floors of six cells, leaving only a thin scale of cement, which could be broken through by a pressure from the foot. The work was commenced November 4, and finished November 24. Thus in twenty days seven men, working one at a time, had accomplished what seemed almost impossible. During these days Calhoun could only wait and hope. As the prisoners passed him in the dining-room, all they could say was “Progressing,” “Not discovered yet,” “All is well so far.” At last, on the 24th, Calhoun heard the welcome words, “Finished. First stormy night.” Calhoun now examined the time-tables and found that a train left Columbus for Cincinnati at 1:15 A. M.; arriving in Cincinnati before the prisoners were aroused in the morning. So he wrote on a slip of paper: “Escape as soon after midnight as possible.” He believed that train could be taken with safety. The afternoon of November 27, the weather became dark and stormy. At supper-time Calhoun heard the glad word, “To-night.” As soon as his duties were done he hurried to the home of Mr. Pettis, exchanged his uniform for citizen’s clothes, telling Mr. Pettis his work at the penitentiary was done, and he had decided to leave. “Ask no questions; it is better that you know nothing,” said Calhoun. Mr. Pettis took his advice, but he was not surprised in the morning when he heard that Morgan had escaped. For General Morgan to escape, it was necessary for him to occupy a lower cell. His brother, Captain Dick Morgan, occupied the cell next to Captain Hines. The Captain, giving up his chance of escaping, effected an exchange of cells with his brother. This was easily accomplished, as they were about of a size, and it was quite dark in the cells when they were locked in.
