I am extremely interested in the Napoleonic Wars despite me knowing next to nothing about them. Can any recommend some works to help me start with the wars? I want to learn about the wars as a whole but I am also especially interested in the naval history of the war.
Unfortunately I don't think it has very much on naval history specifically, but you might want to take a look at our /r/askhistorians book list section on the Napoleonic wars: https://www.reddit.com/r/AskHistorians/wiki/books/europe#wiki_the_french_revolution_.26amp.3B_the_napoleonic_wars
I must recommend
'The Napoleonic Source Book' by Philip J Haythornethwaite.
It covers all of the wars but not in too much detail, features an extensive glossary on terms, includes information on the weapons and tactics of war, mentions all of the combatants of the wars (including the minor German states) and covers their contributions and militaries, it also has detailed sections on things like siege-works, specific battles and lightly touches on the political situations of most countries. As an added bonus it features literally pages of sources from accounts of the people who were there to analysis by expert Historians. Even better, it can be purchased second hand from somewhere like Amazon for very little.
From there it depends on where you want to go, if you want to study Napoleon himself, or his campaigns then there are books focussing more on that but if you want to study particular campaigns or the militaries of nations in greater detail then there are books for that too.
