Intelligence in War: The Value - And Limitations - Of What the Military Can Learn About the Enemy

In fiction, the spy is a glamorous figure whose secrets make or break peace, but, historically, has intelligence really been a vital step to military victories? In this breakthrough study, the preeminent war historian John Keegan goes to the heart of a series of important conflicts to develop a powerful argument about military intelligence. In his characteristically wry and perceptive prose, Keegan offers us nothing short of a new history of war through the prism of intelligence. He brings to life the split-second decisions that went into waging war before the benefit of aerial surveillance and electronic communications. The English admiral Horatio Nelson was hot on the heels of Napoleon's fleet in the Mediterranean and never knew it, while Stonewall Jackson was able to compensate for the Confederacy's disadvantage in firearms and manpower with detailed maps of the Appalachians. In the past century, espionage and decryption have changed the face of battle: the Japanese surprise attack at the Battle of the Midway was thwarted by an early warning. Timely information, however, is only the beginning of the surprising and disturbing aspects of decisions that are made in war, where brute force is often more critical.Intelligence in War is a thought-provoking work that ranks among John Keegan's finest achievements.From the Hardcover edition.

John Keegan, whose many books, including classic histories of the two world wars, have confirmed him as the premier miltary historian of our time, here presents a masterly look at the value and limitations of intelligence in the conduct of war.

Intelligence gathering is an immensely complicated and vulnerable endeavor. And it often fails. Until the invention of the telegraph and radio, information often traveled no faster than a horse could ride, yet intelligence helped defeat Napoleon. In the twentieth century, photo analysts didn’t recognize Germany’s V-2 rockets for what they were; on the other hand, intelligence helped lead to victory over the Japanese at Midway. In Intelligence in War, John Keegan illustrates that only when paired with force has military intelligence been an effective tool, as it may one day be in besting al-Qaeda.
