Codename Nemo: The Hunt for a Nazi U-Boat and the Elusive Enigma Machine

by Charles Lachman

Overview

The white-knuckled saga of the US Navy task force that captured Nazi submarine U-505 and the Enigma machine.

Two days before D-Day—the course of World War II was forever changed. The German hunters of the Atlantic Ocean had become the hunted, and US antisubmarine Task Group 22.3 seized a Nazi U-boat, its crew, and all its secrets. Led by a courageous nine-man boarding party and maverick Captain Daniel Gallery, Operation Nemo was the first seizure of an intact enemy warship in battle since the War of 1812, and the intelligence gathered from it dramatically shortened the duration of the war. But at any moment, the mission could have ended in disaster.

Charles Lachman’s Codename Nemo traces every step of this historic pursuit on the deadly seas, documenting the thrilling cat-and-mouse game through the eyes of the men on both sides. The result is a deeply researched, fast-paced World War II narrative for the ages.

Codename Nemo is a pulse-pounding tale of high-stakes espionage and daring courage, detailing the pursuit and capture of a German U-boat at the height of World War II.

The vivid description of life aboard a U-boat immerse you in the claustrophobic, terrifying world of underwater warfare. As the tension builds, with each 'ping' of the Sonar, the thrilling plot keeps you turning the pages. A riveting narrative combining historical research with visceral scenes, Codename Nemo is a must-read for anyone in search of a thrilling maritime adventure.

The best missions involving submarines often start with an outlandish idea, and the very best make a hell of a story.Codename Nemo does both.

—Sherry Sontag, co-author of the New York Times bestseller Blind Man's Bluff

What a terrific read from Charles Lachman! A suspenseful, fast-paced but little-known saga of hide-and-seek between a US 'baby flattop' and a German U-boat during World War II. Who can resist an Irish-American commander, nicknamed 'Full Flaps' by his crew—always beyond his hearing of course—because of his protruding ears, who embarks with his dog, a border collie named Flabby, instigates nail-biting nighttime takeoffs and landings on his carrier for the first time in Naval history...and if that's not enough, then proposes some cockamamie scheme of commandeering a German sub filled with secret stuff by actually attempting to board her with a nine-man team! It's a wild, engrossing ride from start to finish with extraordinary details and insights into daily life—clashes, arguments, even suicide—aboard both German boats and American ships during the Battle of the Atlantic. This one is a winner!

From the Publisher

2024-02-28
An account of World War II codebreaking focused more on action than brainwork.

Lachman, executive producer of Inside Edition and author of The Last Lincolns and Footsteps in the Snow, explains that the typewriterlike enigma machine generated critical Nazi communication by scrambling input in billions of ways, and German experts never doubted that its code was unbreakable. However, by 1941, the British were deciphering many messages by ordinary codebreaking brilliance, aided by the earliest computers; despite these successes, actual possession of an enigma machine would make their work easier. All U-boats carried one, but crew invariably destroyed it when threatened with capture. No history of the enigma program—including perhaps the best, Stephen Budiansky’s Battle of Wits—neglects the story of how the Allies hit the jackpot on June 4, 1944, but Lachman tells the fascinating story from the beginning. Opening the book with the U-505 launch in August 1941, the author describes its German crew, the often grotesque conditions inside a U-boat, and the nearly three years of campaigning that featured far more tedium and terror than successful attacks. Lachman does the same with significant American ships and sailors, including Daniel V. Gallery, leader of the antisubmarine task force who, unlike other commanders, had publicly vowed to seize a machine. Few readers will object as Lachman recounts the background, and they will perk up just past the halfway point, when he chronicles how sonar detected U-505. In earlier years, the Allies had captured U-boats, though never fast enough to prevent destruction of its secrets, but Gallery had a trained team ready to go. The author delivers a rousing account of its success. Though Lachman doesn’t claim that the capture of U-505 shortened the war, it was a genuinely heroic act that the author recounts capably.

A satisfying World War II history.
