fugitive slave community—new fugitives were arriving—, and as a base for his further invasion of Florida, in 1818 General Jackson directed Lieutenant James Gadsden, of the Army Corps of Engineers, to rebuild the fort, which he did within the earthworks that had protected Negro Fort, as it was much smaller. The fort needed a new name; Jackson named it Fort Gadsden. However, an aide to General Andrew Jackson reported to his superior in August 1818 that Fort Gadsden was "a temporary work, hastily erected, and of perishable materials, without constant repair, it could not last more than four or five years." It was abandoned in 1821, the year Florida became a U.S. territory and there was no longer a national border to defend. Fort Gadsden had no direct involvement in any military endeavor, either in 1818–1821 or during the Civil War. Colinton In 1820, Colin Mitchell would purchase the Forbes Lands, including Fort Gadsden. The following year he made plans to construct a city at the site, Colinton. The planned city would have had 4 squares and wharves for incoming steamboats. However, Mitchell's claim to the land would be found invalid, and Colinton was never built. "Milly Francis" A marker at the site recalls the case of Milly Francis, a Creek girl who persuaded her father, Hillis Hadjo (Francis the Prophet), not to execute an American soldier who had inadvertently come into their territory. Her father was captured and hung at Fort St. Marks in 1818. She witnessed his hanging. Irvington remains A steamboat, the Irvington, burned and sank in 1838 four miles north of the Site. The rusting boilers and some of the works thought to be from this ship were dredged from the river (when the river was being dredged for navigation) and can be seen at the Site. Civil War (1862–1863) During the American Civil War, Confederate troops occupied the fort, using it to protect communications from plantations in Georgia, Florida, and Alabama with the port of Apalachicola. In July 1863, an outbreak of malaria forced its abandonment. Fort Gadsden given disproportionate emphasis at historic site? "The settlement of former slaves has been marginalized in and has largely receded from both the scholarly and popular imagination for much of the last [20th] century." The most important moment in Prospect Bluff's history is arguably the Negro Fort period (1815–1816) and this is the period of significance cited in
