The 2nd Wisconsin, 6th Wisconsin, 7th Wisconsin, 19th Indiana, and later the 24th Michigan were formed into one of the best known fighting brigades in the American Civil War. Initially, the soldiers of the Confederate south knew them as "That damn Black Hat Brigade" but later the unit became known as "Iron Brigade" because they "stood like Iron" in the face of enemy fire. The Iron Brigade (of the west) fought at many of the War's most bloody battles including Antietam and Gettysburg.
