This database of Illinois Civil War Veterans indexes the first eight volumes of the nine volume publication, Report of the Adjutant General of the State of Illinois. (The ninth volume lists veterans of Black Hawk, Mexican, and Spanish-American Wars.) This 1900-1901 publication, originating from the rosters maintained during the Civil War by the Illinois Adjutant General, is the result of an 1899 Illinois statute mandating that a corrected version of these records and subsequent publications be printed. The names of approximately 250,000 men, organized into 175 regiments, are found in its pages. The work includes a roster and history for each regiment.
