Double-Edged Secrets: U.S. Naval Intelligence Operations in the Pacific During World War II (Bluejacket Books) Paperback – January 15, 2013
Assigned to the combat intelligence unit in Honolulu from June 1941 to the end of the war, W. J. Holmes shares his history-making experiences as part of an organization that collected, analyzed, and disseminated naval intelligence throughout World War II. His book not only captures the mood of the period but gives rare insight into the problems and personalities involved, allowing the reader to fully appreciate the painful moral dilemma faced daily by commanders in the Pacific once the Japanese naval codes were broken. Every time the Americans made use of the enemy messages they had decoded, they increased the probability of the Japanese realizing what had happened and changing their codes. And such a change would cause the U.S. Pacific Fleet to lose a vital edge. On the other hand, withholding the information could--and sometimes did--result in the loss of U.S. lives and ships. This revealing study illuminates the difficulties in both collecting intelligence and deciding when to use it.

My bigggest criticism of this book has nothing to do (directly) with Holmes himself. Like many memoirs written in the decades immediately after the war, this book is limited by the fact that much of the information Holmes would otherwise have been able to share was still officially secret. It would be for later researchers to say what Holmes couldn't.
The other complaint I have is that, based on what I've read elsewhere, Holmes modestly understates the important role he played in the events he describes. It's to his credit that he's eager to praise talented and dedicated cryptologists and analysts. But Holmes frequently makes himself sound like someone standing on the sidelines watching the varsity team play. In fact, he was one of the team's key players.
What could be a highly technical memoir is leavened by a light tone and entertaining asides, like his tales of trying to drive through Honolulu with darkened headlights (a feat he describes as probably a greater danger to the citizens of Honolulu than the Japanese attack was).
Any student of the war in the Pacific, and particularly of Naval Intelligence operations or the attack on Pearl Harbor, will find this an interesting and entertaining memoir.
The real-life drama is incredible and the behind-the-scenes constant struggle to break the Japanese codes is gripping. Fascinating, too, is Captain Holmes background information, throughout, on what was going on with the U.S. submarine forces in the Pacific theater, and their troubles with torpedoes and minefields.
Highly recommended.
It's books such as these that give us a really good look into the command decisions of the Pacific theater during the war. I highly recommend this book.
