72nd Regiment Indiana Infantry

The 72nd Indiana Infantry Regiment, also known as 72nd Indiana Mounted Infantry Regiment, was an infantry and mounted infantry regiment that served in the Union Army during the American Civil War. The regiment served as mounted infantry from March 17, 1863, to November 1, 1864, notably as part of the Lightning Brigade (also sometimes, "The Hatchet Brigade"). during the Tullahoma and Chickamauga Campaigns.

Initial infantry service

The 72nd Indiana Infantry was organized at Lafayette, Indiana, and mustered in for a three-year enlistment at Indianapolis, Indiana, on August 16, 1862, under the command of Colonel Abram O. Miller.

Conversion to mounted infantry

In December 1862, the regiment received a new brigade commander, Colonel John T. Wilder. After frustrating chases on foot after mounted rebel cavalry raiders, the brigade was converted to mounted infantry. At the same time, Wilder proposed to the regiments in the brigade the private purchase of repeating rifles. The 72nd voted to go ahead with the conversion to mounted infantry and the purchase of the rifles. Along with the other regiments in the brigade, the 72nd chose Spencer repeating rifles, invented by Christopher Spencer, as their weapon.

After intense training and development of new tactics, the "Lightning Brigade" was ready for service. The mounted infantry proof of concept for the Army of the Cumberland occurred in their first mounted infantry action at the Battle of Hoover's Gap. Despite torrential rains, the 72nd and its brigade gained the gap so quickly that they surprised and scattered surprised the Confederate 1st (3rd) Kentucky Cavalry Regiment, under Colonel J. Russell Butler at breakfast in front of the entrance of the gap. The 72nd drove the enemy before it along the seven mile length of the gap until they were halted by four brigades of infantry and four batteries of guns at the southeastern exit. The massive superiority of firepower the 17th and its brethren had with the Spencers allowed them to entrench and hold the southern entrance against numerous assaults by numerically superior rebel infantry and artillery through the rainy day until the sodden remainder of the XIV Corps slogged to join them at their position.

With the Lightning Brigade, the 72nd found itself detached from the XIV Corps to serve as a mobile reserve for all three of the Corps within the Cumberland. After playing a key role in the feint that forced Bragg from Chattanooga, the regiment raided, skirmished, and scouted through the summer into the Chickamauga Campaign. The brigade distinguished itself with its performance at Chickamauga. During the battle, it maintained integrity and discipline exacting high casualties on its attackers. After the battle, it retreated with the army to Chattanooga where it was besieged.

The performance of the brigade had demonstrated the value of mounted infantry, and Wilder and the regiments were commended. During the reorganization after Grant took command in the city, the brigade was broken up and the regiments were transferred to the Cavalry Corps. The 72nd and the 123rd Illinois were assigned to 3rd Brigade of the 2nd Division of the Cavalry Corps.

Dismounting

In positions at Terrapin Creek in Cherokee County, northern Alabama, the 72nd was dismounted on 1 November. They became a regular infantry regiment armed with Spencers. For the remainder of the war, they operated in the regular infantry role.
