The 6th Indiana Infantry Regiment was an infantry regiment from the State of Indiana that served in the Union Army during the American Civil War. This regiment was the senior Indiana regiment of the Civil War,^[3] as it was numbered first in sequence after the five Indiana volunteer regiments which had served in the Mexican–American War. The regiment was originally mustered-in for a three-month period of service between April and August 1861, but after its initial term of service had expired it was re-formed in September 1861 for a further three-year period, before being mustered out in September 1864.
