Query: Excellent military history from Keegan, as usual

Very good overview of the war as war, with social, technological and diplomatic background. As this is a military history, you may want to supplement your reading of this book with others. Tuchman's 'The Guns of August' on the war's origins; Fussell's 'The Great War and Modern Memory' on the larger social context and impact of the war; Winter's 'Death's Men' for the soldier's view. I also recommend the novel 'A Very Long Engagement' by Japrisot.I would give Keegan's book five stars, but, as others have noted, this book desperately needs more maps.
