John Bell Hood

John Bell Hood (June 1[2] or June 29,[3] 1831 – August 30, 1879) was a Confederate general during the American Civil War. Although brave, Hood's impetuosity led to high losses among his troops as he moved up in rank. Bruce Catton wrote that "the decision to replace Johnston with Hood was probably the single largest mistake that either government made during the war".
Hood returned to field service during the Atlanta Campaign of 1864, and at the age of 33 was promoted to temporary full general and command of the Army of Tennessee at the outskirts of Atlanta, making him the youngest soldier on either side of the war to be given command of an army.
After the war, Hood moved to Louisiana and worked as a cotton broker and in the insurance business. His business was ruined by a yellow fever epidemic in New Orleans during the winter of 1878–79 and he succumbed to the disease himself, dying just days after his wife and oldest child, leaving ten destitute orphans.
