The Confederacy converted some Wilmington-built ships into blockade-runners.
The Cecile brought in more than 2,000 rifles to the South before it was wrecked on a reef in 1862.
The Wilmington-built Austin became the blockade-runner Donegal and made many runs into Mobile before it was captyred and became a supply vessel in the Union Navy.
For some reason, Wilmington shipyards only received limited construction orders from the U.S. Navy. Harlan & Hollingsworth reluctantly agreed to construct three Monitor-class ships. The reason for this was because of the U.S. government's notoriety for not finishing projects quickly.
