Henry Hayes Lockwood
Henry Hayes Lockwood, probably the only army general to be buried in the Naval Academy Cemetery, was born in Kent County, Delaware, August 17, 1814, and was graduated from West Point in 1836. He served in the war against the Seminoles for a time, but resigned in 1837 to become a farmer. In 1841 Lockwood was appointed professor of mathematics at Annapolis; then during the Mexican War he served aboard the frigate United States and took part in the capture of Monterey, California. After the war he was again on duty at the Naval Academy, teaching such subjects as natural philosophy, astronomy, field artillery, gunnery, and infantry tactics. He became colonel of the 1st Delaware Infantry on May 25, 1861, and brigadier general of volunteers on August 8, 1861. During the first two years of the Civil War he had command of the eastern shore of Maryland and Virginia and the defenses of the Lower Potomac. In the Gettysburg campaign he was on active field duty, directing the 2nd Brigade of A. S. Williams' division of Slo-cum's XII Army Corps, two of the three regiments of his command having been recruited from the Potomac area. On July 17, 1863, Lockwood's troops were detached from the Army of the Potomac and ordered to re-enforce the garrison on Maryland Heights across the Potomac from Harpers Ferry. Later that year he was placed in charge of the Middle Department, with headquarters at Baltimore, and in 1864 commanded some provisional troops called out to repel Jubal Early's raid on Washington. After Early's retirement into Virginia, Lockwood was assigned to the command of the "Third Separate Brigade" and a geographical area within the Middle Department which embraced the counties of Frederick, Carroll, Harford, the eastern shore of Maryland, and all of Baltimore with the exception of the coastal defenses; he continued this command until his muster out in 1865. He returned to the Naval Academy and served as professor of natural and experimental philosophy until 1870 when he was assigned to the Naval Observatory in Washington where he remained until his retirement in 1876. He then made his residence in Georgetown, D. C, where he died on December 7, 1899, and was buried at Annapolis.
