Edward "Allegheny" Johnson (April 16, 1816 – March 2, 1873) was a United States Army officer and Confederate general in the American Civil War. Highly rated by Robert E. Lee, he was made a divisional commander under Richard S. Ewell. On the first evening of the Battle of Gettysburg (July 1, 1863), Ewell missed his opportunity to attack Cemetery Hill, and Johnson opted against attacking Culp's Hill, for which he had a discretionary order, though he attempted this on the second and third days. Ewell and Johnson are blamed by many for the loss of this decisive battle. Early life Johnson was born on Salisbury Plantation near current-day Midlothian in Chesterfield County, Virginia, but his family soon moved to Kentucky. He attended the United States Military Academy and graduated (after five years of study) in 1838. He was commissioned a brevet second lieutenant in the 6th U.S. Infantry and was promoted to first lieutenant in less than a year. He served in the Seminole Wars in Florida and then in the West. In the Mexican–American War, Johnson distinguished himself for action at Veracruz, Cerro Gordo, Churubusco, Molino del Rey, and Chapultepec. He received two brevet promotions, to captain and major, during the war and was awarded a ceremonial sword by the state of Virginia for his bravery. Johnson returned to duty on the Western frontier, serving in the Dakota Territory, California, Kansas, and on the Utah Expedition. Civil War After the outbreak of the Civil War, Johnson resigned his United States Army commission and received the rank of colonel in the 12th Georgia Infantry on July 2, 1861. The 12th Georgia fought in Gen. Robert E. Lee's first campaign in western Virginia, at the Battle of Greenbrier River. He was promoted to brigadier general on December 13, 1861, and received his nickname while commanding six infantry regiments in a battle on Allegheny Mountain. (This brigade-sized force was given the grandiose name "Army of the Northwest".) Valley Campaign In the winter of 1861–62, Johnson's army cooperated with Maj. Gen. Thomas J. "Stonewall" Jackson in the early stages of Jackson's Valley Campaign. While Jackson marched his army into the mountains of the present-day Eastern Panhandle of West Virginia to conduct raids on the Baltimore & Ohio Railroad, Johnson was tasked with protecting against a Union invasion of the "upper," more elevated areas of the Shenandoah Valley near Staunton, Virginia.
