MORRIS, B.S., AND HER SENTENCE. CINCINNATI, Feb. 13. The following is Mrs. Morris' confession: McLEAN BARRACKS, CINCINNATI, Feb. 5, 1865. To Maj.-Gen. J. Hooker, Commanding Northern Department, Cincinnati, O.: General--I was arrested in Chicago, on the 11th day of December, by the United States authorities, charged with assisting rebel prisoners to escape, and relieving them with money and clothing; also, with holding correspondence with the enemy. I desire to state the facts of the case, to confess the truth, and to ask such clemency at your hands as may be consistent with your duty as an officer of the government. I was born and reared in Kentucky. My home was in the South till within the last ten years, my connections and friends all being there. I had sympathy with them, though I was as much opposed to the secession movement as any one could be. Having a large acquaintance in Kentucky, I was charged with the distribution of a great deal of clothing and money among the prisoners in Camp Douglas, Chicago, sent to them by their friends, and which was done under the supervision of the proper officers of the camp. This I continued to do up to the time of my arrest, and in this way I made the acquaintance, and was understood to be the friend of the prisoners in camp.
