Fort C. F. Smith (Arlington, Virginia)  Fort C.F. Smith was a lunette that the Union Army constructed in Alexandria County (now Arlington County), Virginia, during 1863 as part of the Civil War defenses of Washington (see Washington, D.C., in the American Civil War). It was named in honor of General Charles Ferguson Smith, who died from a leg infection that was aggravated by dysentery on April 25, 1862. Fort C. F. Smith connected the Potomac River to the Arlington Line, a row of fortifications south of Washington, D.C., that was intended to protect the capital of the United States from an invasion by the Confederate States Army. The Army built the lunette on a bluff overlooking the Potomac River and Spout Run. Because of its elevation and location, the lunette could protect the Aqueduct Bridge from invaders traveling along each of the two waterways. Following the Union Army's defeat at the Second Battle of Bull Run (Manassas) in August 1862, the Army constructed Fort C. F. Smith in 1863. The lunette was located on property that Thomas Jewell had previously owned and that contained a red house. During construction, the fort was therefore referred to "Fort at Red House". The Army destroyed the house while building the lunette and nearby fortifications. The lunette had places for 22 guns and had a perimeter of . General John G. Barnard wrote in a report that "Fort C. F. Smith was carefully planned and constructed after our latest models." The lunette had a southern and western face and two flanks, as well as a crémaillère line on the north side to protect it from attack up the ravines from the river.
