"Former Second Corps commander Jubal Early opened the controversy with an address at Washington Colleg on the anniversary of Lee's birth, January 19, 1872. early focused on Gettysburg, exonerating Lee of mistakes and accusing Longstreet of not attacking promptly on July 2, and of being responsible for the attack on the 3rd. Exactly a year later at the same site, William N. Pendleton, the army's former artillery chief and now a minister, charged Longstreet with failure to obey an order by Lee to attack at sunrise on July 2. This alleged 'sunrise order' became the center of a firestorm. Pendleton either deliberately lied--Lee issued no such order--or memory failed him." [Jeffry D. Wert, General James Longstreet: The Confederacy's Most Controversial Soldier, a Biography, p. 422]
