According to Wikipedia: "Thomas Jonathan "Stonewall" Jackson (January 21, 1824 - May 10, 1863) was a Confederate general during the American Civil War, and probably the most revered Confederate commander after General Robert E. Lee.[2] His military career includes such famous exploits as the audacious Valley Campaign of 1862 and as a corps commander in the Army of Northern Virginia under Robert E. Lee. Confederate pickets accidentally shot him at the Battle of Chancellorsville on May 2, 1863, which the general survived, albeit with the loss of an arm to amputation. However, he died of complications of pneumonia eight days later... Robert Edward Lee (January 19, 1807 October 12, 1870) was a career military officer who is best known for having commanded the Confederate Army of Northern Virginia in the American Civil War."
