Indiana regiments were again called to national action in the American Civil War, the costliest engagement in terms of lives the state was ever involved in. Indiana in the war committed over 200,000 soldiers and casualties topped 35% among the men. During the war several regiments where mustered for duty on the home front creating the Indiana Legion which officially separated the militia from the army regiments. Today's 152nd Infantry Regiment traces part of its history to the 6th and 8th Indiana Volunteer Infantry Regiments which fought in the Civil War. The state's regiments were renamed the Indiana National Guard in 1895.
