The Battle of Simmon's Bluff was a minor and bloodless Union victory, fought June 21, 1862, near Charleston, South Carolina, during the American Civil War.
Union forces had laid siege to Charleston, which was being resupplied from a nearby railroad. Union forces were eager to capture the city, so they sent the 55th Pennsylvania Infantry regiment to sever the rail line. The 55th Pennsylvania departed by sea shortly before the battle in search of a place to land closer to the railroad. On June 21, the 55th Pennsylvania came ashore at Wadmelaw Sound. Union forces discovered an encampment of the 16th South Carolina Infantry regiment, and quickly razed the encampment and engaged the Confederate forces. The Confederates scattered after the encampment was razed and were unable to launch an effective counterattack. There were no reports of injuries on either side. After the raid, the Union forces returned to their ships and abandoned their original objective, which was to interrupt the rail line to Charleston.
