Query: Not Keegan at his best but still good work

While not as eloquent in depicting the true nature of war as fictional accounts are able to because of their more flexible formats, 'The First World War' can measure up to and even exceed the popularity of spellbinding war novels like 'The Triumph and the Glory' and 'All Quiet on the Western Front' because John Keegan has such a great understanding of conflict and presents it in such a manner that the reader can't help but turn the page. I hope he keeps writing military history for a long, long time. Bravo.
