Query: Bad History

Green Hell is bad history. Owens is a journalist not an historian and it shows. The book draws primarily on secondary sources and is riddled with the same errors that have plagued earlier works. Moreover, there are no maps. Owens solicited inputs from veterans and these accounts, when they appear in the book, are simply wonderful. Indeed, they're the only thing which raises this book to the level of mediocrity. If you want an accurate and informative work on the Guadalcanal campaign, read Richard B. Frank's book.
