The master and commander books by Patrick O'Brian are great also, well researched descriptions of naval warfare during Napoleon's wars.
The best historical fiction I've ever read, and the audiobooks by Patrick Tull are also really good.
R.A. Lafferty's Fall of Rome.
Hillary Mantel's book on Cromwell too are top notch historical fiction.
I think they are just about middling historical fiction, compared to War and Peace or even Ivanhoe or Gore Vidal's novels about American History like Burr.
That's your personal opinion, ain't it. I haven't read the books you mentioned, will give a try. War and Peace is there in my reading list since long.
