Fort Clinch is a 19th-century brick fortress begun in 1847 after the end of the Second Seminole War. It was named in honor of General Duncan Lamont Clinch, important figure in the First and Second Seminole Wars. No battles were fought at Fort Clinch. Confederate troops occupied the incomplete fort in 1861 when Union forces were withdrawn from Florida. In 1862 Confederate forces were withdrawn from the fort because their manpower was needed elsewhere and Union forces regained control of the area without any shots being fired. Union forces restarted construction of the fort and continued through the end of the war. The fort would become a base of operations for Union forces in the area for the remainder .
