Civil War Subversion Investigations

During the American Civil War (1861-1865), various Executive Orders and acts of Congress conferred the power to investigate suspected secessionists and suspected disloyal/treasonable activities. Nearly 63,000 case files were compiled first by Associate Judge Advocate Major Levi C. Turner and later by the War Department (under General Lafayette C. Baker). The Turner files mostly relate to the arrest, parole, and release of suspects, while the Baker files include reports submitted by private individuals and government officials relating to suspicious persons and alleged subversive activity. A case file may contain one document or several hundred.
