3.5 stars, rounded upward.

Code Name Nemo is the true story of how U.S. Naval Commander Dan Gallery and his men captured a German U-boat during World War II. My thanks go to NetGalley, Diversion Books, and Dreamscape Media for the review copies. This book will be available to the public June 4, 2024.

German U-boats were brilliantly engineered submarines that were the terror of the seas for Allied forces in the Atlantic theater during World War II. They were extremely difficult to detect, and were responsible for sending not only Allied ships, but also Merchant Marine vessels and other commercial craft to the bottom of the ocean. Until Gallery took the initiative to capture one, the U.S. Navy had been hard pressed just to sink the treacherous subs rather than be sunk by them. To capture one was an intelligence coup of the highest order, providing the Allies with not only the technical details of the U-boats themselves, but also a host of military secrets kept onboard, including the codes that in turn led to the plans and locations of other German subs.

No Naval officer had even attempted such a thing before. Nazis were expected to destroy their subs rather than allow them to be taken; this, even if it meant all or part of the crews had to drown with the vessels. But lately, it was known that there were sailors that were conscripted and who were not Germans, men from conquered European nations. Gallery believed that some of these men would now choose to surrender and live, rather than drown themselves for the Fuhrer. Gallery was right.

Lachman does a presentable job of describing the events leading up to the sub’s capture, and he chooses to tell it from dual perspectives, and so we see it through both American eyes and those of the Germans. I am not a fan of this trend. For starters, I don’t see this as a good time, if such exists, to depict Nazis as warm and fuzzy fellows that just happened to be on the losing side of history. Furthermore—and I’ve said it before, so forgive me if you are my longtime reader and growing sick of my saying this—you never see historical writers take this tack when detailing the events of the Pacific theater. It’s as if there’s an implied requirement, saying, Look here. We are all (Caucasian) human beings, after all.

That aside, I enjoyed this book, particularly the most exciting part when they board the sub and have to prevent its exploding, or sinking fast along with the U.S. sailors that have come on deck. There is a certain amount of information dumping up front that slows things down a bit up front, and that might also confuse a reader or listener trying to remember the many names and personal histories of those involved. I can see the reasoning behind all of it; some of those mentioned in this book will have descendants that swell with pride as they hear of the courage and cleverness of their great-great whatevers, and who may be devastated to see their late relative omitted. However, the narrative would flow better if the details were streamlined.

I primarily use the audio version, with the Kindle version as backup for rechecking facts. Some of the time I used both at once. Qarie Marshall is the reader for the audio, and does an outstanding job of taking me back in time, once the story gets moving.

The research is adequate, but not stellar. Certain sources get the lion’s share of use, primarily Dan Gallery himself, who has written at length about his experience. I found myself wondering, from time to time, if I would have been better served to read his own account rather than this one. But by then I had this one well underway, so I went with it.

Those that enjoy military history might enjoy this story, and for them, I rate this book four stars. As a general read for history buffs, it may be more of a three star read. If you are the latter and considering reading it, you may want to get it free or cheap, rather than investing full cover price.
