Hornblower: Duty

If you have read CS Forester's "Hornblower and the Hotspur" you are wondering where it went. While a few incidents are present here from the book, the story line has nothing to do with the book. You will be disappointed that the main themes and character of Horatio have been lost. While the series is entertaining, do not expect the TV movies to be the books. "Based on" is used in its very broad sense.

So watch the movies first. Then go read the books, they are much richer and complex. However, the character of Hornblower will be vastly different and the historic settings as well. Unfortunately, another example of taking the reputation of a book, some names and some of the incidents and then writing your own story without the depth of the original.

So, just treat them as separate works with name connections only.
