In Charleston Harbor, Massachusetts troops clear the advanced rifle pits in front of Fort Wagner
As the works of Union engineers closed in on Fort Wagner, guarding Charleston Harbor on Morris Island, several attempts were made to clear the advanced Confederate pickets in rifle pits about two hundred yards in front of the fort. The 24th Massachusetts carried out the final successful assault against the 79 defenders of the 61st North Carolina, killing or capturing 76 of them. Fort Wagner was evacuated ten days later.
