Like one of Field Marshal Haig's family whiskies, Max Hastings is a dram that steadily improves with age. His own trenchant views on war, and caustic opinions of the commanders who ran them, tended to obtrude too obviously in his early work, suggesting that if only he had been present at key military conferences costly errors would have been avoided.
However, Hastings' recent massive volumes on his specialist subject, World War II, have shown why his position as a leading military historian is now unassailable. They demonstrate not only his always formidable grasp of the nuts and bolts of logistics and strategy and an authoritative narrative sweep, but a new humane note of empathy.
In this enormously impressive new book, Hastings effortlessly masters the complex lead-up to and opening weeks of World War I. As a historian, his objective is twofold: to pin the principal blame for launching the catastrophic conflict where it rightly belongs: on Austria and Germany; and to argue unashamedly that Britain was right - politically and morally - to fight it.
In advancing these arguments, Hastings takes on two foes: first, revisionist historians such as Cambridge's Professor Christopher Clark, who have recently sought to exculpate Germany and put tiny Serbia in the dock as the chief villain, for organising or conniving in the assassination of Austrian Archduke Franz Ferdinand at Sarajevo - the spark that gave Vienna and Berlin a perfect excuse to set off the conflagration.
Hastings' second adversary is more amorphous: what he calls "the poets' view" of the war as a futile struggle for a few blood-drenched yards of mud, which wasted a whole generation, solved nothing and which Britain should have steered clear of, allowing those funny foreign fellows to slaughter each other without compromising its splendid isolation.
