Why am I passionate about this?

I spent more than five years researching and writing a book about the Japanese submarine force during World War II—a topic virtually untouched by western historians. My research took me to Japan where I interviewed surviving members of the Imperial Japanese Navy’s Sixth Fleet—its submarine branch. These men told incredible stories of what it was like to serve aboard a Japanese sub during World War II; stories filled with courage, fear, pathos, and humor revealing the universality of the human condition. I remained moved by them to this day.

The books I picked & why

Book cover of I-Boat Captain

John J. Geoghegan Why I love this book

This is the first book I’ve ever read written by a Japanese sub commander that describes submarine warfare from the Japanese point of view. Few Japanese sub commanders survived the war, so how Orita lived to tell the tale is just one of the many remarkable stories he recounts in his book. Not only does it read like a suspense thriller, you’ll have newfound respect for the suffering he and his crews went through. Bottom line: The Japanese version of Das Boot!

Book cover of Operation Drumbeat: The Dramatic True Story of Germany's First U-Boat Attacks Along the American Coast in World War II

John J. Geoghegan Why I love this book

Few people understand just how lousy the East Coast of the United States was with U-boats during the opening months of World War II. Operating with virtual impunity, they sank tankers and merchant ships up and down the coast for nearly a year before the U.S. finally organized an effective defense. Gannon does an excellent job both setting the scene and relating the history of the U-boat war—a story that few people know but will keep you riveted.

What is this book about?

Operation Drumbeat is the story of Germany's first deliberate attacks against the United States in World War II. The attacks took the form of torpedo launchings, and deck-gun actions by submarines, called U-boats, against American and Allied freighters and tankers steaming with war cargoes along the U.S. Atlantic Coast, in the Caribbean, and across the Gulf of Mexico during the first eight months of 1942.

By August, the number of sinkings reached nearly 400, with loss of over 5,000 U.S. and Allied merchant seamen and sailors-twice the number of fatal casualties at Pearl Harbor the preceding December. In his magisterial…

Book cover of Sunk: The Story of the Japanese Submarine Fleet, 1941-1945

John J. Geoghegan Why I love this book

Hashimoto was the Japanese sub captain of the I-58, who sank the USS Indianapolis shortly after it delivered the atomic bomb in the closing days of World War II. The story of the Indianapolis has been told in several excellent books including, “In Harms Way” and “Fatal Voyage” as well as the movie, “Jaws,” but never from the Japanese point of view. How Hashimoto and his crew survived the war is integral to this story which makes The Hunt for Red October seem like child’s play. And it’s all true!

What happened to Japan’s submarines and what sort of fight did they put up?

As far as Japan was concerned, the recent war was waged according to a rigid strategy. There was no detailed operational planning. It was a fight in which science had been ignored. In such circumstances the submarine, always highly vulnerable unless used intelligently, was inevitably sacrificed. Throughout the war the whole submarine fleet was in reality a special attack force in which, in the absence of scientific weapons, the crews were just so much human ammunition. Today we hear much about rearmament. If money is to…


Book cover of Undersea Victory: The Influence of Submarine Operations on the War in the Pacific

John J. Geoghegan Why I love this book

Undersea Victory is the definitive history of submarine warfare in the Pacific during World War II. Holmes was a giant in the field and really knows his stuff. You’ll come away having a much greater appreciation for how sub combat operations were conducted both by the U.S. and Japan. Importantly, Holmes doesn’t hesitate to tell you the good and the bad regardless of which side he’s writing about. No sub enthusiast’s library is complete without it.

Book cover of Run Silent, Run Deep

John J. Geoghegan Why I love this book

This is one of the classics that started it all. Although fiction, Beach was a sub commander during World War II who fought against the Japanese. As a result, he really knows his stuff. The sometimes fraught personal dynamics between sub commanders and their first officers (as well as the crew) are one of the driving forces of this narrative. And you’ll never forget Bungo Pete!

Why should I read it?

1 author picked Run Silent, Run Deep as one of their favorite books, and they share why you should read it.

What is this book about?

Universally praised for its powerfully authentic depiction of submarine warfare, Run Silent, Run Deep was an immediate success when published in 1955 and shot to the top of best-seller lists. The New York Times said of it, "If ever a book had a ring of reality, this is it. . . combat passages rank with the most exciting written about any branch of the service." The Saturday Review called the book "a classic," and many reviewers compared its author to such greats as C.S. Forester and Erich Remarque. Today these accolades still ring true for Edward L. Beach's gripping first…

Operation Storm: Japan's Top Secret Submarines and Its Plan to Change the Course of World War II

By John J. Geoghegan ,

Book cover of Operation Storm: Japan's Top Secret Submarines and Its Plan to Change the Course of World War II

What is my book about?

Operation Storm tells the true but little-known story about a squadron of gigantic submarines purpose-built by Japan to launch a surprise aerial attack against New York City and Washington, D.C. as a follow-up to Pearl Harbor. These 18 subs, more than twice as big as any sub ever built, were essentially underwater aircraft carriers that could launch attack bombers, which they housed in a water-tight deck hangar, off their bow using a pneumatic catapult. Although the subs were on their way when Japan surrendered, the flagship sub went rogue determined to complete its mission. The Wall Street Journal called, Operation Storm, “A fascinating, meticulously researched, and deft account.”
