The veteran “Iron Brigade,” one of the toughest units in the army, was comprised of five regiments from Wisconsin (2nd, 6th and 7th), Michigan (24th) and Indiana (19th). Gettysburg was the Iron Brigade’s finest hour during the Civil War but also it’s deadliest. The 24th Michigan lost 363 of their 496 soldiers and the 2nd Wisconsin incurred 233 causalities out of 302 soldiers.
