Hunley was built at Mobile, Alabama, and launched in July 1863. The sub tested successfully in Mobile Bay by sinking a coal flatboat. She was then shipped by rail on August 12, 1863, to Charleston. The Diver was designed and built in late 1862 and ready for trials by January 1863.
An unsuccessful attack on the Union blockade of Mobile was attempted in February 1863. She sank in Mobile Bay later that same month during stormy weather, the ship was not recovered and remains in an undiscovered location somewhere near the entrance of the bay to the present day.
