Perhaps the best single source for researching Civil War shipwrecks is a set of books titled The Official Records of the Union and Confederate Navies in the War of the Rebellion. These records include official correspondence, dispatches, excerpts from vessel logs, etc. and are an excellent source of contemporary records relating to shipwrecks. These wrecks range from powerful ironclad warships to flimsy merchant steamers. It was by using these records that Dr. E. Lee Spence located numerous blockade runners, including the Norseman and Stonewall Jackson.
