They're decent books but ultimately dissapointing because he abandonned the series. He hasn't release one since 1996. They exist in the same universe as the Sharpe series the proof of which is the presence of Sharpe's son, a French Colonel on an observation mission, and I enjoyed them when I read them years ago. From what I recall they're very much follow the typical Cornwell formula of fictional male protagonist gets involved in a war and plays a central but role in events, has a few significant enemies he has to defeat, makes some interesting friends and always ends up in the arms of a beautiful girl or two along the way - and, if its anything like the Sharpe series, any younger officer who gets close to the main protagonist always dies. Anyway, I read them once and enjoyed them, I might dust them off one of my bookshelves and read them again and enjoy them, and I'd read any new ones in the series and probably enjoy them as well, but whether they could be considered amungst the best of the fiction based around the Civil War I could not judge.
