At the end of the War of 1812 between the United States and Great Britain, and the defeat of the Creek Indian Nation at Horseshoe Bend in Tennessee, General Andrew Jackson retired to his home in Tennessee. Since Spain did nothing to control the Florida Indians who were raiding into South Alabama and Southwest Georgia stealing the cattle and raiding the plantations, Andrew Jackson was recalled from retirement to lead a force of volunteers and friendly Indians into West Florida in 1818. Jackson captured the fort at Wakulla then marched across North Florida to capture Pensacola, seeking contact with the Indian chiefs along the route. This area included the land that would become Bay County. The Adams-Onis Treaty of 1819 allowed the U.S. to purchase Florida from Spain for five million dollars. Florida formally came under U.S. control in 1821. Andrew Jackson was appointed by President James Monroe to become the first Military Governor of the Florida Territory.
