74th Indiana Infantry Regiment  The 74th Indiana Infantry Regiment, officially known as the 74th Regiment, Indiana Volunteer Infantry, was an infantry regiment that served in the Union Army during the American Civil War. The 74th Indiana Infantry was organized at Fort Wayne, Indiana and mustered in for a three-year enlistment on August 21, 1862, under the command of Colonel Charles W. Chapman. The regiment was attached to 2nd Brigade, 1st Division, Army of the Ohio, September 1862. 2nd Brigade, 1st Division, III Corps, Army of the Ohio, to November 1862. 2nd Brigade, 3rd Division, Center, XIV Corps, Army of the Cumberland, to January 1863. 2nd Brigade, 3rd Division, XIV Corps, to October 1863. 3rd Brigade, 3rd Division, XIV Corps, to June 1865. The 74th Indiana Infantry mustered out of service at Washington, D.C. on June 9, 1865. As the Battle of Chickamauga began on the morning of 19 September, George Henry Thomas sent John Croxton's brigade to capture a Confederate brigade reported by Colonel Daniel McCook to be trapped on the west side of Chickamauga Creek. The brigade moved down a parallel trail between the Reed's Bridge road and the Brotherton road, forming line of battle in an adjacent pine forest. The 74th Indiana held the right of the line, with the 10th Indiana to its left. With Croxton's brigade, the regiment fired engaged the 10th Confederate Cavalry of Henry Davidson's brigade, who were scouting the area, routing it before the Confederates came closer than rifle range. The brigade then resumed the advance, being halted by the dismounted cavalry of Davidson's brigade in forested terrain at the base of a ridge west of Jay's Mill Road, where the opposing forces exchanged fire. Despite poor visibility, the fire of Croxton's brigade caused Davidson's brigade to thrice temporarily retreat from the ridge. When Claudius Wilson's Georgia Brigade, sent in to bolster the Confederate defense, attacked across the Brotherton road shortly after 09:00, they were spotted by Chapman, but his order for the right flank companies to retreat to face the Confederate advance was misunderstood as an order intended for the entire regiment, causing a general retreat. However, Croxton prevented the Confederates from taking advantage of this by shifting the 10th Kentucky from the brigade left to the right. After a volley from the 10th Kentucky stopped Wilson's advance, Chapman reformed the regiment on their right.
