Florida Territory
Beginning in late 1835, Osceola and the Seminole allies began a guerrilla war against the U.S. forces. Numerous generals fought and failed, succumbing to the heat and disease as well as lack of knowledge of the land. It was not until General Thomas Jesup captured many of the key Seminole chiefs, including Osceola who died in captivity of illness, that the battles began to die down. The Seminoles were eventually forced to migrate. Florida joined the Union as the 27th state on March 3, 1845. By this time, almost all of the Seminoles were gone, except for a small group living in the Everglades.
History of Florida
Following Abraham Lincoln's election in 1860, Florida joined other Southern states in seceding from the Union. Secession took place January 10, 1861, and, after less than a month as an independent republic, Florida became one of the founding members of the Confederate States of America. As Florida was an important supply route for the Confederate Army, Union forces operated a blockade around the entire state. Union troops occupied major ports such as Cedar Key, Jacksonville, Key West, and Pensacola. Though numerous skirmishes occurred in Florida, including the Battle of Natural Bridge, the Battle of Marianna and the Battle of Gainesville, the only major battle was the Battle of Olustee near Lake City.
