Thomas Jonathan "Stonewall" Jackson (January 21, 1824 – May 10, 1863) served as a Confederate general (1861–1863) during the American Civil War, and became one of the best-known Confederate commanders after General Robert E. Lee.[2] Jackson played a prominent role in nearly all military engagements in the Eastern Theater of the war until his death, and had a key part in winning many significant battles.
When faced with a larger Union army now commanded by Joseph Hooker at Chancellorsville, Lee divided his force three ways. On May 2, Jackson took his 30,000 troops and launched a surprise attack against the Union right flank, driving the opposing troops back about two miles. That evening he was accidentally shot by Confederate pickets. The general lost his left arm to amputation; weakened by his wounds, he died of pneumonia eight days later.
