During the Civil War, Wakulla County was blockaded from 1861-1865. Confederates took control of San Marcos de Apalache. They changed the name to Fort Ward. The Battle of Natural Bridge stopped the Union force that tried to take Fort Ward and nearby Tallahassee. Tallahassee was the last Confederate state capitol that the Union had not captured. The Union forces were not able use all their soldiers. They still had more soldiers than the Confederates. The Confederates chose to fight at a place where the St Marks River goes underground. This was the "Natural Bridge' the battle was named for. The Confederates had over a day to get ready for the battle. The Union could not win and left. Most of the people who died in the battle were African-American soldiers fighting for the Union. A celebration was held in Tallahassee. It was stopped when a telegram arrived telling them about General Lee's surrender at Appomattox.
