Fort Marion located at St Augustine, Florida was a small Union Army garrison with one Sergeant on January 7th 1861, when it was taken over by about 25 Florida State Militia from Fernandina, Florida. The Sergeant received a receipt for the fort from the Confederacy and it was surrendered without a shot. Three days later the state of Florida seceded from the Union. On March 11th 1862 Union Marines landed from the USS Wabash and USS Mohican without opposition and were able to reoccupied St Augustine and Fort Marion. The Fort was used as a military prison for the rest of the Civil War.
