Alt Text Map of the historic harbor at Fort Sumter and Fort Moultrie National Historical Park in South Carolina during the American Civil War. Land is shown in tan and water in pale blue. Confederate locations are labeled with red text and Federal locations are labeled with blue text. Extended Description James Island fills most of the lower left quadrant of the map, and Morris Island lies next to it to the east. The Ashley River separates James Island from Charleston in the top left corner, and Cooper River separates this from Sullivans Island in the upper right quadrant. The Ashley and Cooper rivers connect to Charleston Harbor at the heart of these islands, and the Atlantic Ocean is to the east. Fort Sumter and Fort Moultrie are labeled in black on the mouth of Charleston Harbor. Fort Sumter is in open water, and Fort Moultrie sits on the shore of Sullivans Island to the north. Another fort, Fort Wagner, is south of the harbor opening on Morris Island. Blue text under Fort Sumter reads “Federal 1861” and red text reads “Confederate 1861-1865.” Red text under Fort Wagner reads “1861-1863” and blue text there reads “1863-1865.” Southwest of Fort Wagner on Morris Island and in the lower middle of the map, blue text reading “Swamp Angel” is in quotation marks and dated 1863, also in blue. In the lower right corner and in the Atlantic Ocean, blue text reads “Ironclad attack, April 7, 1863.” A blue dashed line next to it representing the main ship channel curves up into the mouth of the harbor. Within the harbor are six Confederate locations labeled in red, including a battery at Cummings Point on Morris Island, a battery and Fort Johnson on James Island, Castle Pinckney on a small island near the mouth of Cooper Island, and a battery and a floating battery on Sullivans Island. Legend A scale in the bottom left corner of the map measures distances of 1 and 2 kilometers and 1 and 2 miles. Red text in the upper right corner reads, “Confederate locations shown in RED” and blue text reads, “Federal locations shown in BLUE.”
