United States territorial acquisitions
West Florida was declared to be a U.S. possession in 1810 by President James Madison after the territory had declared its independence from Spain. Madison ordered the U.S. Army to take control. Six weeks later, the army entered and occupied the capital, St. Francisville, putting an end to the republic after 74 days of independence. Spain did not relinquish its claim to sovereignty (see West Florida Controversy) until ratification of the Adams–Onís Treaty. General Andrew Jackson personally accepted the delivery of West Florida from its Spanish governor on July 17, 1821.
History of Florida
When the Colonies declared independence, many Floridians condemned it. They had been almost unaffected (because East and West Florida were backwoods areas) by the Stamp Act Crisis of 1765, which led the 13 colonies to perceive a common interest threatened by Britain. Florida declined to send delegates to the Continental Congress. The majority of Floridians were Loyalists, grateful to the Crown, that remained loyal to Britain. Many actually helped lead raids on the American South. One disastrous attempt on the part of the American Forces to invade East Florida occurred at the Battle of Thomas Creek in today's Nassau County. It was led on May 17, 1777. American Colonel John Baker surrendered to the British. Another attempt, the Battle of Alligator Bridge took place on June 30, 1778.
