Francis Channing Barlow (1834 – 1896) was a lawyer, politician, and Union General during the American Civil War. On July 1, 1863, Barlow, who was 29 years of age at the time, commanded a division at the Battle of Gettysburg. While awaiting the expected Confederate assault, Barlow left his assigned position to move to higher ground on Blocher's Knoll (now known as Barlow's Knoll). His move left the remaining XI Corps division, that of Maj. Gen. Carl Schurz, at risk, and exposed both of his own flanks. The Confederates took advantage of his error: Maj. Gen. Jubal Early's division overwhelmed Barlow's division and forced the retreat of the entire XI Corps with great loss. Barlow himself was wounded and left for dead on the field. He was found and cared for by Confederate Brig. Gen. John B. Gordon, who sent him to a field hospital. (Source: Wikipedia)
