An interesting document may be read at American Memory. It is a claim for remuneration of the survivors and officers (Stephen Decatur commanding but only a Lieutenant) and crew of the ketch Intrepid for the destruction of the frigate Philadelphia at Tripoli in 1804. They were asking for $100,000. Further documents indicate that this dragged through Congress for several sessions. In one document he is referred to as Commodore, the title apparently posthumous.
Further documents detail the application for pension relief by Susan Decatur, his wife, after Decatur's death (only a Captain). Apparently this case went on for years.
