Intelligence in War

An essential book at a critical time, by the worlds leading military historian From the earliest times, military leaders have sought out information on the strengths and weaknesses of the enemythe more detailed and specific, the better. The strategy of divide and conquer, usually based on regional intelligence, underlay many of the greatest exploits of empire building from Alexander the Great to modern times. In this magisterial new study, the author of A History of Warfare brings his brilliant analysis to bear on the role military intelligence played in key conflicts from the early nineteenth century to September 11, 2001. From the Napoleonic wars to the sophisticated electronic warfare of the 21st century, John Keegan finds linking themes that lead to a compelling conclusion: War is ultimately about doing, not thinking. In combat, force always counts more than foreknowledge. John Keegans narrative sweep is enthralling, whether portraying the dilemmas of Nelson seeking Napoleons fleet, Stonewall Jackson in the American Civil War, Bletchley seeking to crack Ultra during the Battle of the Atlantic, or the often-elusive intelligence issues of the contemporary fight against terrorism.(October 2003)
