Nicolls' Outpost was the smaller and more northern of two forts built by British Lt. Col. Edward Nicolls during the War of 1812. (The Americans referred to it as Fort Apalachicola. Built at the end of 1814, together with the larger "British post" or storage depot down the Apalachicola, it was "the northernmost post built by the British during their Gulf Coast Campaign". It was just below the Spanish Florida–Georgia border, where the Flint and Chattahoochee Rivers meet to form the Apalachicola, in River Landing Park in modern Chattahoochee, Florida. Even though what was built was smaller than the much larger British post down the Apalachicola, it was intended to be the base, presumably enlarged, for an English invasion of the United States, and British post was to have been its supply depot. The 1815 end of the War of 1812 aborted this project.
