river was of intense interest to the British, who saw it as an undefended entry into the United States through Georgia. It was of no interest to the Spaniards; it led nowhere they cared about. Spanish forces in Florida were limited and Spain was far less committed to Florida than it was to its other colonies, most of them much more productive. Spain's inability to police its borders or return fugitive slaves was central to Florida's transfer to the United States in 1821. Control of Prospect Bluff meant control of the river, which had served as a transportation artery for centuries. More recently, it had enabled raiding parties to go upriver into Georgia and the Mississippi Territory via the Chattahoochee and especially the Flint River. The attacks were made on plantations, which had few if any defenses. These parties, besides coming back with material goods, saw to it that the slaves of the raided plantations could get free. This was a great economic blow to the slave owners (slaves were expensive), and an ideological affront as well, leaving them insecure and angry. Prospect Bluff was valuable militarily not only because of the elevation its name suggests, but because it was at a "strategic location", a bend in the river, giving an important sight advantage over any boat. Before 1814 The Florida panhandle was mostly wilderness before 1814. Its population at the time is unknown, except for isolated reports. As in the rest of Florida, there were many Native American refugees from the United States, who merged into a new ethnicity, Seminoles. It provided excellent cover for escaped slaves, who, since they shared a common enemy, got along with the Seminoles fairly well; "over time, a bond developed between escaped Africans and the Seminoles that only increased with time and white pressure for their return". Some became black Seminoles. There was "reciprocal respect and affection"; the former slaves, who knew English, served as interpreters. This predecessor of the Underground Railroad ran south. The biggest issue about the area discussed by whites was how to get escaped slaves back, or get compensation for them, and prevent or reduce future escapes. The return of Native Americans was unwanted, and they were soon forcibly removed from Florida as well. As was customary in pre-railroad times, settlement took place first along rivers. The name Apalachicola derives from the Apalachee who settled along it in pre-colonial
