When President Abraham Lincoln proclaimed a blockade of the entire southern coastline, the US Navy only had 93 warships, and almost half of these were outdated or unusable. So, the US Navy went on a buying spree purchasing every steamer that could mount cannons. One of these vessels was the St. Mary which was soon commissioned as USS Hatteras. In turn, the Confederacy did not have a navy and sought to obtain ships overseas to attack Northern merchant ships. The most successful of these commerce raiders was CSS Alabama. These two warships would have a fatal encounter on January 11, 1863, off Galveston, Texas, resulting in the sinking of USS Hatteras.
