The 11th Regiment Illinois Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War. It was originally formed as a three-month volunteer unit at the beginning of the war, and then reorganized as a three-year unit, in which role it served until the end of the war. Using only the above description and what you know about the world, "The 11th Regiment Illinois Volunteer Infantry was recognised as a unit after the start of the war" is definitely correct, incorrect, or inconclusive?
