The 73rd Indiana Infantry (Union) was an infantry regiment organized at South Bend, Indiana, and mustered into Federal service on August 16, 1862. Serving in the Western Theater, the regiment participated in major campaigns and engagements across Kentucky, Tennessee, Alabama, and Georgia. The 73rd Indiana was noted for its involvement in Streight’s Raid and its determined defense at Athens and Decatur, Alabama.
The regiment served the Union cause from its organization in 1862 until its mustering out in July 1865, seeing action in several significant operations and enduring periods of hard campaigning, capture, and parole.
Organization & Service
The 73rd Indiana Infantry was organized at South Bend, Indiana, and mustered in on August 16, 1862. The regiment departed the state immediately for Lexington, Kentucky, then moved to Louisville in early September. It was assigned to the 20th Brigade, 6th Division, Army of the Ohio (Buell’s army), and participated in the pursuit of Confederate forces under Bragg. The regiment was held in reserve at the Battle of Perryville and continued the pursuit as far as Wild Cat, Kentucky.
Following operations in Kentucky, the regiment returned to Glasgow and then moved to Gallatin, Tennessee, where it engaged and drove Confederate forces from the field, capturing 19 prisoners. The 73rd Indiana marched into Nashville on November 26, 1862, and subsequently moved to Lebanon, Tennessee, where it was involved in a skirmish. It then joined Rosecrans’ army for the advance on Stone’s River, crossing the river on December 29, 1862, and engaging in heavy skirmishing and combat during the Battle of Stones River. The regiment suffered significant casualties in this engagement and was commended by General Rosecrans for its conduct.
In April 1863, the 73rd Indiana was assigned to Colonel Streight’s independent provisional brigade, mounted at Eastport, Mississippi, and participated in Streight’s Raid into Georgia. The regiment fought at Day’s Gap, Crooked Creek, and Blount’s Farm, where Colonel Hathaway was killed. Surrounded and exhausted at Cedar Bluffs, the brigade surrendered; enlisted men were paroled and later exchanged, while officers were sent to prison.
After returning to duty, the regiment was stationed along the Louisville & Nashville Railroad, with headquarters at Triune, Tennessee, performing guard duty and engaging in minor actions. It was later attached to the 1st Brigade, 4th Division, 20th Corps. In the summer of 1864, the regiment defended Prospect, Tennessee, against Wheeler’s raid, and in September moved to Decatur, Alabama, and then to Athens, where it successfully repulsed an attack by Buford’s cavalry. The regiment also participated in the defense of Decatur against Hood’s army in October 1864.
The 73rd Indiana spent the winter of 1864–1865 on railroad guard duty at Stevenson, Huntsville, and Larkinsville, Alabama, engaging in several skirmishes. The regiment was mustered out at Nashville, Tennessee, on July 1, 1865. Remaining recruits were transferred to the 29th Indiana Infantry.
