The St. Johns River has been a strategic waterway for centuries. During the Civil War, the Union blockade of Jacksonville and the St. Johns River was pivotal in maintaining a strong coastal and interior blockade of the southeast coast. The successful Union blockade of the Atlantic seaboard prevented supplies and goods from entering and leaving the Confederacy.
Florida voted to secede from the United States and to join with other Southern states in the Confederacy in 1861. Although few actual battles were fought in Florida during the Civil War, the state nonetheless played an important role for both sides in the conflict.
