After the battle, Fort Sumter remained a Confederate stronghold.

After the battle, Fort Sumter stood as a Confederate stronghold for the majority of the Civil War. Following the Union's surrender on April 13, 1861, the Confederacy reinforced the fort and utilized it as a vital military base in Charleston Harbor. It became a symbol of Southern defiance and was essential to the Confederacy's coastal defense strategy. Confederate forces maintained their occupation of the fort until it was subjected to intense bombardment and ultimately seized by Union troops in February 1865. This change represented a crucial turning point in the war, as the Union regained control of this strategic site.
