The Battle of Natural Bridge was a battle during the American Civil War, fought in what is now Woodville, Florida, near Tallahassee, on March 6, 1865. A small band of Confederate troops and volunteers, mostly composed of teenagers from the nearby Florida Military and Collegiate Institute that would later become Florida State University, and the elderly, protected by breastworks, prevented Union forces (consisting of African-American soldiers of the United States Colored Troops) from crossing the Natural Bridge on the St. Marks River.
