The 600-acre National Battlefield (near Murfreesboro, Tennessee) includes Stones River National Cemetery, established in 1865, with more than 6,000 Union graves; and the Hazen Brigade Monument, believed to be the oldest, intact Civil War monument still standing in its original location.

The Battle of Stones River was one of the bloodiest of the war. More than 3,000 men lay dead on the field. Nearly 16,000 more were wounded. Some of these men spent as much as seven agonizing days on the battlefield before help could reach them. The two armies sustained nearly 24,000 casualties, which was almost one-third of the 81,000 men engaged.
