The Diehards, 1991 (oil on canvas) During Porter’s Second Bull Run attack on Stonewall Jackson’s position along Stony Ridge the afternoon of August 30, 1862, Confederate soldiers in the Unfinished Railroad Cut—their ammunition all but gone—resort to throwing rocks at the Federals. After a devastating two hours, Porter’s men finally retreated, with nothing gained but an extensive casualty list. (Don Troiani/Bridgeman images) Don Troiani/Bridgeman images
