"Alan T. Nolan's "The Iron Brigade" is a classic of Civil War literature." - Gary W. Gallagher. "I am immensely impressed...This particular Brigade needed a book of its own and now it has one which is definitely first-rate...A fine book..." - Bruce Catton. "One of the '100 best books ever written on the Civil War.'" - "Civil War Times Illustrated." "Alan Nolan has written a first-rate account of one of the most famous fighting outfits of the Army of the Potomac, the Iron Brigade...Nolan's book is unit history writing at its best, and it adds much to our knowledge of the larger story of the war..." - T. Harry Williams. This is the story of the most famous unit in the Union Army. Originally called "The Black Hat Brigade" because soldiers wore the army's regular dress black hat instead of the more typical blue cap, the "Iron Brigade" was the only all-Western brigade in the Eastern armies of the Union. The brigade was initially made up of the 2nd, 6th, and 7th Wisconsin and the 19th Indiana Volunteers; later it was reinforced by the 24th Michigan Volunteers. Battery B of the 4th U.S. Artillery, composed in large part of infantry detached from the brigade, was closely associated with it.
