OK, it doesn't say which civil war so I'll tell you. It's the American Civil War. That really gets on my nerves but that's the bad part over and done with.
Anyhoo...This large format book is exquisite with each page detailing a different ship from the conflict including ship stats and a complete history, complemented with colour illustrations. There are also some double page spreads with beautiful full colour illustrations of specific battles with a write up about the action in question. At the back of the book, there are alphabetical lists of all the boats from the ACW detailing the type of ship and its size.
If you are an ACW gamer or would like to become one, this is THE book to buy. Really, find it and buy it now!
