David Ward, historian at NPG, discusses Stonewall Jackson. At the First Battle of Manassas in July 1861, the unrelenting vigor with which Confederate General Thomas Jonathan Jackson held his position inspired a general nearby to rally his troops with the cry, "There is Jackson standing like a stone wall." From that moment on, he was known as "Stonewall" Jackson, a name that he repeatedly lived up to, fighting under the command of General Robert E. Lee.The deeply religious Jackson believed intensely in the righteousness of the southern cause, and a key to his success was his ability to instill his own fighting fervor in his men. One of his most brilliant victories came at Chancellorsville in the spring of 1863. Tragically for Jackson and the South, this would prove to be his last battle, as he died of wounds accidentally inflicted by his own men. Recorded at NPG, May 20, 2010.
