Daniel Adams Butterfield was a New York businessman, a Union general in the U.S. Civil War, and Assistant Treasurer of the United States. After working for American Express, co-founded by his father, Butterfield served in the Civil War, where he was soon promoted brigadier general, and wounded at Gaines' Mill. While recuperating, he wrote a bugle call for burials, called Taps. He commanded a division at Fredericksburg, and then became General Joseph Hooker's chief of staff for the Army of the Potomac, sharing both the credit for improved morale and responsibility for the licentious behavior that Hooker tolerated in camp. He also became embroiled in Hooker's political feuds with Generals Ambrose Burnside and George Gordon Meade. When Meade took over the Army from Hooker, he attempted to replace Butterfield, but his chosen candidates preferred to stay in their current assignments, so Butterfield stayed on as chief of staff, to Meade's dissatisfaction. Wounded at Gettysburg, Meade sent Butterfield away to recuperate. He then served in William T. Sherman's Atlanta campaign, before retiring from front-line service because of illness. He later received the Medal of Honor. In Ulysses S. From Wikipedia (https://en.wikipedia.org/wiki/Daniel_...) under Creative Commons Attribution CC-BY-SA 3.0 (http://creativecommons.org/licenses/b...)
