In April, 1862, the First Brigade, First Division, First Army Corps was the first unit to be designated the "Iron Brigade." (The same name would later be given to the Second Brigade.) This original Iron Brigade consisted of the 2nd U.S. Sharpshooters, the 22nd, 24th, and 30th New York Volunteer Infantry, and the 14th Brooklyn. In February, 1901, the Brooklyn Daily Eagle printed this poem, written by a former member of Company A, 30th New York.
Many thanks to Marc A. Hermann of the 14th "Brooklyn" Regiment, N.Y. State Militia, Company H, for contributing this poem.
