American Civil War

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. While commanding a regiment, a brigade, a division, and a corps in the Army of the Potomac, he saw action at Bull Run, the Peninsula, South Mountain, Antietam, Chancellorsville, and Harpers’ Ferry. At Gettysburg, he was the senior Union General in the Field. During the battle, he held the Union right from Culp’s Hill to across the Baltimore Pike. His successful defense of Culp’s Hill was crucial to the Union victory at Gettysburg. After the fall of Vicksburg, Slocum was appointed military commander of the district. Slocum participated in the Atlanta campaign and was the first commander to enter the city on September 2, 1864. He then served as occupation commander of Atlanta. Slocum was appointed the commander of the left wing of Sherman’s march through Georgia and the Carolinas, commanding the XIV and XX Divisions, comprising the Army of Georgia. During this campaign, he captured the capitol of Georgia, Milledgeville, and the seaport of Savannah. In the Carolinas campaign, Slocum’s army saw victories in the battles of Averasborough and Bentonville, North Carolina. The March to the Sea and the Carolinas campaign were crucial to the overall Union victory in the Civil War. After the surrender of Confederate forces, Slocum was given command of the Department of Mississippi. Slocum declined an appointment in the postwar Army. He was a successful political leader, businessman and railroad developer.

Slocum was born in Delphi, a hamlet in Onondaga County, New York. His father was Matthew B. Slocum, and his mother was Mary Ostrander. He attended the state school in Albany and the Cazenovia Seminary and worked as a teacher. He obtained an appointment to the United States Military Academy at West Point in 1848, where he did well academically, graduating seventh of 43 in the class of 1852. He tutored his roommate, cadet Philip Sheridan, in mathematics. In his memoirs, Sheridan credited Slocum with helping him pass his examination and graduate from the academy. Slocum was commissioned a second lieutenant in the 1st U.S. Artillery on July 1, 1852. He served in the Seminole War in Florida and at Fort Moultrie in Charleston Harbor, South Carolina. While stationed there, he went on leave to marry Clara Rice in 1854. They had four children. Slocum was promoted to first lieutenant on March 3, 1855. He resigned his commission October 31, 1856, and settled in Syracuse, New York.
