The 21st Ohio Volunteer Infantry Regiment Monument, situated in Fort Oglethorpe, Georgia, stands as a testament to an infantry regiment that served valiantly in the Union Army during the American Civil War. Despite the Confederate victory at Chickamauga Battlefield, where the monument now stands, the 21st Ohio played a crucial role in the stand made by General Thomass forces on Snodgrass Hill. The regiment was initially assembled in Findlay, Ohio, and enlisted on September 19, 1861, serving until its discharge in Louisville, Kentucky, on July 25, 1865.

This monument is a twenty-two-foot tall obelisk made of Italian marble, topped with the emblematic American flag sculpted around its pinnacle. The five-foot pedestal bears the regiments name and other inscriptions detailing their service during the war. Inside, you will find engraved facts about both Union and Confederate soldiers, a list of regiments that participated in the conflict, descriptions of notable battles, sources for the information provided, and more. This historical marker offers an insightful glimpse into the history of the 21st Ohio Volunteer Infantry Regiment and their significant contributions to the American Civil War.
