You can read a little of the book Africa Squadron and the book reviews on amazon. com. I am glad some of you found this interesting. You may also know that in 1819 a law was passed called the Slave Trade suppression act which allowed the navy to operate off Africa. In 1820 the law was changed to make slave trading the same as piracy which carried the death penalty. Only one man was hung for this crime. Most of the rest either got short jail sentences of a few years and were often pardoned !? Some slave ships that were captured were confiscated but in other cases the judge through the case out and the ship was released. In a few cases the Captains of the USN ships that captured the slave ships were sued by the slave ship owners!? This was a frustrating time for the USN however in the 1858-1861 period the US finally sent an adequate force to operate off Africa the squadrons success rate increased.
As for dueling before this time there was a lot of dueling between officers in the USN and around this time the Navy decided to put a stop to it. Also note: there was still dueling going on between civilians in the US even a few cases of women dueling women. I know some of this sounds a little strange but things like this did happen.
