A skilled military tactician, he served as a Confederate general under Robert E. Lee in the American Civil War, leading troops at Manassas, Antietam and Fredericksburg. He is remembered today for being a brilliant strategist (his war strategies & tactics are still studied today) and he was one of very few people that were aligned with the Confederacy to hold sympathy for African American slaves.
