Well-written, cohesive account, but rather conventional in approach and also distinctly coloured in places by (possibly inevitable) pro-English bias - Keegan seems too kind to Haig, for example, and rather too inclined to make excuses for his major defeat in the great German offensive of March 1918. He is best in his account of the actual fighting, sometimes myopic or partial in his overviews and political comments. Excellent purely as narrative, but Niall Ferguson's recent The Pity of War offers a far much trenchant and up-to-date analysis of possibly the greatest historical tragedy which ever befell Europe, both Central, Eastern and Western.
