Organization & Service
The 85th Indiana Infantry was organized at Terre Haute, Indiana, and mustered in on September 2, 1862. Shortly after organization, the regiment moved to Covington, Kentucky, then to Falmouth, and later to Danville, Kentucky, where it remained until February 1863. It was then ordered to Franklin, Tennessee.
In March 1863, while on a forage and scouting expedition with its brigade, the regiment engaged Confederate forces at Thompson’s Station. After several hours of fighting, the brigade was surrounded and compelled to surrender. The 85th Indiana suffered heavy losses and was taken prisoner, with the men sent to Libby Prison in Richmond, Virginia, until exchanged on March 31, 1863.
After exchange, the regiment returned to Franklin in June 1863, engaging in skirmishing and fighting until the Confederate army under Bragg retreated. The 85th Indiana spent the summer, fall, and winter at Murfreesboro, Tennessee, performing railroad guard duty.
On April 20, 1864, the regiment joined the Union forces for the Atlanta Campaign, participating in the battles of Resaca, Cassville, Dallas, Golgotha, Kolb’s Farm, and Peachtree Creek. The regiment was engaged in all operations before Atlanta and was present at its capture.
Following the Atlanta Campaign, the 85th Indiana took part in the Savannah Campaign, including the siege and capture of Savannah. On January 1, 1865, its division was the first to cross into South Carolina, driving back Confederate cavalry. The regiment remained in the swamps near the Savannah River until February, then joined the march through the Carolinas. At Averasboro, it led a brigade charge under heavy fire, and at Bentonville, it participated in key actions, including constructing defensive works under fire.
The regiment continued through Goldsboro, Raleigh, Richmond, and finally to Washington, D.C., where it was mustered out on June 12, 1865. Remaining recruits were transferred to the 33rd Indiana Infantry and served until July 21, 1865.
