39th Indiana Infantry Regiment
The 39th Indiana Infantry Regiment was a Union Army unit in the American Civil War. It was organized in Indianapolis and mustered in for a three-year enlistment on August 29, 1861. The regiment served in the Army of the Ohio and later the Army of the Cumberland, fighting in the Horn Brigade (also known as the Dutch Brigade or the Iron Brigade of the Army of the Cumberland).
The 39th Indiana Infantry fought at Shiloh, Corinth, Stones River, and Chickamauga, and took part in the Chattanooga campaign, including battles at Lookout Mountain and Missionary Ridge. In April 1863, the regiment received horses and Spencer rifles and became mounted infantry, serving in the Tullahoma Campaign and at Chickamauga as part of its new role.
On October 15, 1863, the unit was renamed the 8th Indiana Cavalry. After the change, it continued to operate in Kentucky and Tennessee, with duties at places such as Muldraugh’s Hill, Camp Nevin, Nolin Creek, and Green River, and through various marches and engagements in pursuit of Confederate forces.
The regiment suffered heavy losses during its service, with a total of 398 men lost: 9 officers and 138 enlisted men killed or mortally wounded, and 1 officer and 250 enlisted men dying of disease.
