Sent Away. – On Saturday morning 655 Abolition prisoners left the Libby prison for City Point, in charge of Lieut. La Touche. John T. Kirby, a Canadian, who had been for some time in Castle Thunder on suspicion of being a spy, was also sent off. While here, and at starting, Kirby always avowed himself a friend of the South; but he had accumulated so much suspicion against himself that he could not succeed by habeas corpus or otherwise in getting himself out of prison, and adopted the expedient of going North to gain his liberty. One hundred of the Yankee officers taken at Chancellorsville were included amongst the Abolition prisoners who left Saturday morning. There remain now about 200 prisoners of war, including 135 officers.
