Fort DeRussy: The March Strike That Opened the Red River
Event: Battle of Fort DeRussy, Louisiana
Date: March 14, 1864
On March 14, 1864, Union forces struck Fort DeRussy in Louisiana during the opening phase of the Red River Campaign. It was a fast, aggressive attack, and it mattered because Fort DeRussy guarded the lower Red River approaches to Alexandria and Shreveport. Once it fell, the Union gained an early foothold in a campaign designed to push deeper into Louisiana and tighten pressure on the Confederacy west of the Mississippi.
The fort had a reputation for strength. American Battlefield Trust notes that it was partly iron-plated and believed to be formidable. But when Union troops under Gen. Joseph A. Mower, operating in conjunction with the larger expedition, hit the position, the defense unraveled quickly. The Confederate garrison was small, the Union force was much larger, and the post was overwhelmed. The result was a clear Union victory, the capture of the fort, and the opening of the route upriver.
Fort DeRussy does not always get the attention of the war’s headline battles, but that is a mistake. In old-fashioned military terms, this was a classic lesson: strike a key point, force open a corridor, and shape the campaign before the bigger clashes arrive. The Red River Campaign would later become far more complicated and controversial, but in mid-March the Union looked strong and on the move. Scholarly and historical treatments of the Red River fighting consistently place Fort DeRussy at the campaign’s front end as an operational success that set the next phase in motion.
For a battlefield history audience, Fort DeRussy is a reminder that not every important Civil War story is a three-day slugfest. Sometimes a campaign turns because one river fort falls at the right moment. In March 1864, Fort DeRussy was that moment.
