About A. P. Hill
Ambrose Powell Hill Jr. (November 9, 1825 – April 2, 1865) was a Confederate general who was killed in the American Civil War. He is usually referred to as A. P. Hill to differentiate him from Confederate general Daniel Harvey Hill, who was unrelated. A Virginian, Hill was a career United States Army officer who had fought in the Mexican–American War and Seminole Wars before joining the Confederate States Army. After the start of the American Civil War, he gained early fame as the commander of the "Light Division" in the Seven Days Battles. He became one of Stonewall Jackson's ablest subordinates, distinguishing himself in the 1862 battles of Cedar Mountain, Second Bull Run, Antietam, and Fredericksburg. Following Jackson's death in May 1863 at the Battle of Chancellorsville, Hill was promoted to lieutenant general and commanded the Third Corps of Robert E. Lee's Army of Northern Virginia, which he led in the summer Gettysburg campaign and the fall campaigns of 1863. His command of the corps in 1864–65 was interrupted on multiple occasions by illness, from which he did not return until just before the end of the war. He was killed during the Union army's offensive at the Third Battle of Petersburg. June 1 was the first day Hill began using a nickname for his division: the Light Division. He became the brother-in-law of future Confederate cavalry generals John Hunt Morgan (Hill's best man at the wedding) and Basil W. Johnston's army that was transported by the railroad as reinforcements to the First Battle of Bull Run, but Hill and his men were sent to guard the Confederate right flank near Manassas and saw no action during the battle.
