SUMMARY The Stonewall Brigade was a collection of five Virginia infantry regiments and an artillery battery in the Confederate Army of Northern Virginia during the American Civil War (1861–1865). Trained and first led by Thomas J. “Stonewall” Jackson, it was perhaps the most accomplished and certainly one of the most famous units of its kind in American military history. The brigade saw action in many of the bloodiest battles of the war, from First Manassas (1861) to Antietam (1862) to Gettysburg (1863) to Spotsylvania Court House (1864), losing only a single engagement under Jackson’s command but also losing more than 96 percent of its men by 1865.
