Rhode Island sent 23,236 men to fight in the Civil War. They served in eight infantry regiments, three heavy artillery regiments, three regiments and one battalion of cavalry, a company of hospital guards and 10 batteries of light artillery. Hundreds more served in the U.S. Army, Navy and Marine Corps. Rhode Islanders participated in nearly every major battle of the war, firing the first volleys at Bull Run, and some of the last at Appomattox.

How many died in the Civil War is a question that has long eluded historians. Drawing on a twenty-year study of regimental histories, pension files, letters, diaries, and visits to every cemetery in the state, award-winning Civil War historian Robert Grandchamp documents 2,182 Rhode Islanders who died as a direct result of military service. Each regiment is identified, followed by the name, rank and place of residence for each soldier, the details of their deaths and, where known, their final resting places.
