Union soldiers built the Hazen Brigade Monument in 1863, just six months after the Battle of Stones River, at a time when the war’s outcome was still uncertain. Unlike most Civil War battlefield monuments, which were erected 30 or more years after Appomattox, this one was laid up by comrades of the men buried here rather than civilian contractors. Travelers on the Nashville and Chattanooga railroad saw it as a constant reminder of what it cost Hazen’s Brigade to stand fast all day at Stones River. It is the oldest intact Civil War monument in the nation. Buried here are soldiers from the 6th Kentucky Volunteer Infantry, 41st Ohio Volunteer Infantry, 9th Indiana Volunteer Infantry, and 110th Illinois Volunteer Infantry, along with two unknown soldiers from Illinois. Colonel William B. Hazen, a 31-year-old West Point officer, commanded this brigade of four volunteer infantry regiments, and more than 400 of his troops fell in battle here.
