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.
West Florida Controversy
In 1810, a group of discontented American and British settlers in the area of Baton Rouge learned that the Spanish colonial governor, who had feigned sympathy, was in fact mounting a force against them. They revolted by overrunning a Spanish garrison at Fort San Carlos in Baton Rouge on September 23, 1810, and declared the independence of the Republic of West Florida on September 26. On October 27, the United States president proclaimed that the territory should be annexed, and Spain, then embroiled in the Peninsular War with France, could do little to resist. On December 10, the United States military completed the forcible occupation and acquiescence of the Republic of West Florida.
