At Gettysburg
Commander: Maj. Gen. Henry Warner Slocum (September 24, 1827 – April 14, 1894), was a Union general during the American Civil War and later served in the United States House of Representatives from New York. During the war, he was one of the youngest major generals in the Army and fought numerous major battles in the Eastern Theater and in Georgia and the Carolinas. Controversy arose from his conduct at the Battle of Gettysburg, where he was accused of indecision and a dilatory advance to the battlefield, earning him the derogatory nickname “Slow Come”.
