Lewis Addison Armistead

Lewis Addison Armistead (February 18, 1817 – July 5, 1863) was a career United States Army officer who became a brigadier general in the Confederate States Army during the American Civil War. On July 3, 1863, as part of Pickett's Charge during the Battle of Gettysburg, Armistead led his brigade to the farthest point reached by Confederate forces during the charge, a point now referred to as the high-water mark of the Confederacy. However, he and his men were overwhelmed, and he was wounded and captured by Union troops. He died in a field hospital two days later.
Lewis Armistead is buried next to his uncle, Lieutenant Colonel George Armistead, commander of the garrison of Fort McHenry during the Battle of Baltimore, at the Old Saint Paul's Cemetery in Baltimore, Maryland.
