Fort Moultrie – Charleston, South Carolina:
In the months leading up to the Civil War John L. Gardner was in command at Fort Moultrie. With secession growing more imminent, Gardner had made several requests to Secretary of War John B. Floyd for more troops to garrison and defend the undermanned fortress. Each time his requests were ignored, as Floyd (who joined the Confederacy) was planning to hand the forts in Charleston Harbor over to the secessionists.
South Carolina seceded from the Union on December 20, 1860. Around this time a Federal garrison from the 1st US Artillery was sent to Fort Moultrie. Unlike the state militia at the other forts, the Regular Army defenders of Fort Moultrie chose not to surrender to the South Carolina forces. On December 26, 1860, Union Major Robert Anderson moved his garrison from Fort Moultrie to the stronger Fort Sumter. On February 8, 1861, South Carolina joined other seceded Deep Southern states to form the Confederate States of America. In April 1861, Confederate troops shelled Fort Sumter into submission and the American Civil War began.
In April 1863, Federal ironclads and shore batteries began a bombardment of Fort Moultrie and the other forts around Charleston harbor. Over the ensuing twenty months, Union bombardment reduced Fort Sumter to a rubble pile and pounded Fort Moultrie below a sand hill, which protected it against further bombardment. The Rifled cannon proved its superiority to brickwork fortifications but not to the endurance of the Confederate artillerymen who continued to man Fort Moultrie. In February 1865, the Confederate Army finally abandoned the rubble of Fort Moultrie and evacuated the city of Charleston. – wikipedia
