Lt. Gen. Thomas J. "Stonewall" Jackson is pictured here. Artillery professor at Virginia Military Institute. Considered "Lee's Right Arm", Jackson helped to lead the Army of Northern Virginia to victory at the First and Second Manassas, the Valley Campaign of 1862, Seven Days Battles, Fredericksburg, and Chancellorsville. Jackson was a victim of friendly-fire at the Battle of Chancellorsville in 1863 and would soon die of pneumonia resulting from his wounds.
