Daniel Harvey Hill, or more commonly D. H. Hill, (July 12, 1821 - September 24, 1889) was a Confederate Major general during the American Civil War. He was an officer in the Mexican-American War and received two brevet promotions for his performance; one to captain and another to major. He left the army to become a Professor. When North Carolina seceded from the Union, Hill was appointed Colonel of the 1st North Carolina Infantry. By 1862 he was a major general serving in the Army of Northern Virginia. Hill's reputation was tarnished over the lost copy of Special Order 191 which fell into the hands of Union general George McClellan. This gave away Robert E. Lees plans for the Confederate Maryland Campaign. He was considered a military genius by some, including Lieutenant general Stonewall Jackson (his Brother-in-law).
