Jules Verne 
Blockade Runners [EPUB ebook] 

The American Civil War plot centers on the exploits of James Playfair who must break the Union blockade of the harbour of Charleston in South Carolina to trade supplies for cotton and, later in the book, to rescue the father of a young girl held prisoner by the Confederates. Verne’s tale was inspired by reality as many ships were actually lost while acting as blockade runners in and around Charleston in the early eighteen sixties. (Excerpt from Wikipedia)
