The Battle of Natural Bridge was fought during the American Civil War in what is now Woodville, Florida near Tallahassee on March 6, 1865. A small group of Confederate troops and volunteers, which included teenagers from the nearby Florida Military and Collegiate Institute that would later become Florida State University, protected by breastworks, prevented a detachment of United States Colored Troops from crossing the Natural Bridge on the St. Marks River. The Natural Bridge is a stretch along which the St. Marks River runs underground, after dropping into a sinkhole. Battle The Union's Brig. Gen. John Newton had undertaken a joint force expedition to engage and destroy Confederate troops that had attacked at Cedar Keys, Florida and Fort Myers and were allegedly encamped somewhere around St. Marks. The Union Navy had trouble getting its ships up the St. Marks River. The Union Army force, however, had advanced and, after finding one bridge destroyed, started before dawn on March 6 to attempt to cross the river at Natural Bridge. The Union troops initially pushed Rebel forces back, but not away from the bridge. Sailors from USS Hendrick Hudson also participated, and two were awarded the Medal of Honor for their part in this battle: Seaman John Mack and Coxswain George Schutt. Confederate forces under Brigade General William Miller, protected by breastworks, guarded all of the approaches and the bridge itself. The action at Natural Bridge lasted most of the day, but, unable to take the bridge in three separate charges, the Union troops retreated to the protection of the fleet. Based on the involvement of the students from the Florida Military and Collegiate Institute, the Florida State University Reserve Officer Training Corps (ROTC) program is one of only four Army ROTC programs to have a battle streamer for their actions in the Civil War. Since it was originally part of the Army, FSU's Air Force ROTC unit also displays the same battle streamer. Monument The site of the battle is now Natural Bridge Battlefield State Historic Site, a Florida State Park, and contains a monument with the inscription: It is notable that even though the inscription claims that Tallahassee was the only capital of the South not captured by the Union during the Civil war, in actuality Austin Texas was also not captured during the war and never had enemy troops in any direction from it in a 100 mile radius,
