Intelligence in War

Knowledge of the Enemy from Napoleon to Al-Qaeda


A masterly look at the value and limitations of intelligence in the conduct of war from the premier military historian of our time, John Keegan.

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.

In The Press

“[Keegan] brings to the literature of war a deep affection for revealing details, and it’s clear that he loves to be surprised by what he learns. His pleasure animates the material for his readers.”
National Post

“Keegan has not set out to debunk intelligence. Rather he has sought to place the clandestine underbelly of war in perspective, to wrest it from the popular imagination as some sort of entertaining shortcut to victory.”
The New York Times

“Read Keegan’s Intelligence in War for its wonderful narration and genuine insights into the details of intelligence operations.”
The Globe and Mail
