Case of Charles Kopperl.

Charles Kopperl, of Carroll County, Miss., was arrested in New York August 17, 1861, and by didrection of the Secretary of State was conveyed to Fort Lafayette. Kopperl was charged with having been in the military service of the so called Confederate States. The affidavit of J. M. Wardwell, of New York who was in Mississippi in April, 1861, states that in conversation with Kopperl he learned that he was then engaged in raising a cavalry company, and that he was captain thereof. The company was for the Confederate service. He made no secret of the business he was engaged upon. November 1, 1861, Kopperl with others was transferred to Fort Warren, Boston, Mas. January 30, 1862, and ordered was issued from the Departmentm of State directing Colonel Dimick to release Kopperl on his parole of honor to return into custody at Fort Warren within thirty days unless within twenty days Hugh Watson, who was captured at Pamlico Sound, should be released by the insurrectionary government and sent within the lines of the U.
