As white settlers moved into Florida, demands grew to remove the Seminole Indians to a western reservation. The Seminoles did not cooperate, and the Second Seminole War began in 1835. By 1841, the Indians were still entrenched in central and south Florida, and campaign plans for that year aimed to clear Indians from the area between the Withlacoochee River and the frontier and then attack Indian bands in Big Cypress Swamp. To support widely dispersed troops, detached camps were established at various points. Camp Ogden, named for Captain Edmund Ogden of the 8th U.S. Infantry, appears to have been established in July 1841 as an advanced position for the Big Cypress campaign. In addition, 55 canoes were built for the next winter's Everglades expedition. Before the camp was abandoned in the fall, the influential Indian leader Coacoochee visited Camp Ogden. The community of Fort Ogden later developed in this citrus and cattle region in the last part of the 19th century and took its name from the Second Seminole War camp. Fort Ogden's post office, established in 1876, is the oldest in DeSoto County to have remained in continuous service.
