“The large number of prisoners confined in this house, near 300, together with a scanty allowance of provisions, occasioned it to be very sickly. * * * George Barnard, who had been a midshipman on the Hancock, and who was confined in the same room as myself, concerted a plan to release us, which was to be effected by digging a small passage under ground, to extend to a garden that was behind the prison, and without the prison wall, where we might make a breach in the night with safety, and probably all obtain our liberty. This plan greatly elated our spirits, and we were anxious to proceed immediately in executing it. “Our cabins were built one above another, from the floor to the height of a man’s head; and mine was pitched upon to be taken up; and six of us agreed to do the work, whose names were George Barnard, William Atkins, late midshipmen in the Hancock; Lemuel Towle of Cape Ann, Isaiah Churchill of Plymouth; Asa Cole of Weathersfield, and myself. “We took up the cabin and cut a hole in the plank underneath. The sugar house stood on a foundation of stone which raised the floor four feet above the ground, and gave us sufficient room to work, and to convey away the dirt that we dug up. “The instruments that we had to work with were one scraper, one long spike, and some sharp sticks; with these we proceeded in our difficult undertaking. As the hole was too small to admit of more than one person to work at a time we dug by turns during ten or twelve days, and carried the dirt in our bosoms to another part of the cellar. By this time we supposed we had dug far enough, and word was given out among the prisoners to prepare themselves for flight. “But while we were in the midst of our gayety, congratulating ourselves upon our prospects, we were basely betrayed by one of our own countrymen, whose name was Knowles. He had been a midshipman on board the Boston frigate, and was put on board the Fox when she was taken by the Hancock and Boston. What could have induced him to commit so vile an action cannot be conceived, as no advantage could accrue to him from our detection, and death was the certain consequence to many of his miserable countrymen. That it was so is all that I can say. A few hours before we were to have attempted our escape Knowles informed the Sergeant of the guard of our design, and by his treachery cost his country the lives of more than one hundred valuable citizens,--fathers, and husbands, whose return would have rejoiced the hearts of now weeping, fatherless children, and called forth tears of joy from wives, now helpless and disconsolate widows. “When we were discovered the whole guard were ordered into the room and being informed by Knowles who it was that performed the work we were all six confined in irons; the hole was filled up and a sentinel constantly placed in the room, to prevent any further attempt.
