Battlefield Memorial Park commemorates one of the bloodiest battles of the American Revolution, whose combatants reflected the international nature of the conflict. Here on October 9, 1779, a combined force of 5,500 American, French, and Haitian soldiers (as well as Swedish, Polish, and German troops), advanced on the British at Spring Hill Redoubt in a failed attempt to recapture the city, resulting in some 800 American and allied casualties (commemorated by squares of Georgia granite) compared to roughly 100 for the British. The site was later used by the Central as a freight yard for lumber, resin, and turpentine. The nearby repair shops were reached by a branch from the main line that crossed Louisville Road over an iron bridge (demolished in 1974) near the bottom of the hill. The (British) Spring Hill Redoubt was reconstructed by the Coastal Heritage Society in 2007 based on archaeological remains of the original structure identified by a marker to the west.
