Burning of the frigate Philadelphia in Tripoli harbor, 16 February 1804
Chart by Charles Wellington Furlong, 1904, depicting (by dot and dash lines) the course followed by the ketch Intrepid, under Lieutenant Stephen Decatur, as she entered and left Tripoli harbor on her mission to destroy the captured USS Philadelphia. Heavy dashed line indicates Philadelphia's drift after she was set afire. Position A marks Philadelphia's position when boarded by Decatur's men, while B is the location of her wreck when Furlong located it about a century later and recovered artifacts. Position X (just west of the Jerba Passage) is the location of Intrepid's wreck after she blew up on 4 September 1804, during another mission into Tripoli harbor.
