The Civil War Sailor and Soldier Database

Very nice.

The Civil War Soldiers and Sailors System is a computerized database containing very basic facts about servicemen who served on both sides during the Civil War. The initial focus of the CWSS is the Names Index Project, a project to enter names and other basic information from 6.3 million soldier records in the National Archives. The facts about the soldiers were entered from records that are indexed to many millions of other documents about Union and Confederate Civil War soldiers maintained by the National Archives and Records Administration.
