Lillebælt was a Danish 22-gun warship launched in 1801. The Danes surrendered her to the Royal Navy in 1807 and she became the 20-gun post ship HMS Little Belt. In a single-ship action in 1811 while the United States of America was at peace with Great Britain, USS President fired on Little Belt, ostensibly believing her to be HMS Guerriere, which had recently impressed a sailor from USS Spitfire. History is not sure who fired first, both sides claiming the other had fired initially. This action was the eponymous "Little Belt affair". British captain Arthur Batt Bingham maintained that the Americans fired first and that although his vessel had suffered heavy casualties he had not at any time surrendered. Little Belt was broken up in 1819.
