The American Civil War Research Database is the definitive online resource for researching the individuals, regiments, and battles of the American Civil War. Originally created by Historical Data Systems, Inc., the database contains indexed, searchable information on over 4 million soldiers and thousands of battles, together with 15,000 photographs. With thousands of regimental rosters and officer profiles, the database will continue to grow as new information is loaded semiannually. Send comments to janalyn-moss@uiowa.edu
