Fort DeRussy (Louisiana)

Fort DeRussy occupies a quiet stretch of central Louisiana, but its remaining earthworks once anchored Confederate defenses along the lower Red River Valley. Constructed in 1862 as an earthen stronghold with associated water batteries, the position was part of a broader effort to control critical river traffic and shield the interior of Louisiana. Named for Colonel Lewis G. DeRussy, a veteran engineer educated at West Point and long active in Louisiana’s military and civil infrastructure, the site reflects mid-19th-century thinking about fortification in a riverine environment. The fort endured Union naval attack in 1863 and then fell in March 1864 during the opening phase of the Red River Campaign, when forces under A. J. Smith overran the works and captured its garrison and heavy guns. Today, as a state historic site and a listed property on the National Register of Historic Places, Fort DeRussy offers an instructive example of how vulnerable earthen Civil War fortifications were to changing operational realities, and how modern preservationists piece together battlefield landscapes from surviving trenches, riverbanks, and archival maps.
