During most of the American Civil War the Florida city of St. Augustine was under Union control. Its Confederate history was exceedingly brief. One Union general and one Confederate general were natives of the Ancient City. Many officers on both sides (including Union General William T. Sherman and Confederate General Braxton Bragg) had previous military experience in St. Augustine, particularly during the Second Seminole War.
Florida state militia took the fort at St. Augustine from a small U. S. Army garrison (one soldier) on January 7, 1861. Three days later the state of Florida seceded from the United States. Union troops reoccupied the city on March 11, 1862, putting St. Augustine under Union control. The city was never retaken by Confederate forces.
