For reading this 21 book series it's worth investing into one more book with background information.

I can recommend

Patrick O'Brian's Navy: The Illustrated Companion to Jack Aubrey's World (Hardcover)

Lots of valuable information, lots of illustrations and schematics and photos.

I’m on book three and this is incredibly useful. The level of detail in the books is insane. I also reallllly liked the Russell Crowe movie, and wish they had made more. It wasn’t perfect, but it was fun as hell, and the napoleonic wars provide so much material for sequels.
