Gamble in the Coral Sea: Japan's Offensive, the Carrier Battle, and the Road to Midway

by Michał A. Piegzik

The opening salvos of the Battle of the Coral Sea, the first large-scale carrier clash in history, were fired one month before Midway. Gamble in the Coral Sea recounts, for the first time in English, the story of this battle from the Japanese point of view. Based on extensive Japanese-language sources, author Michał A. Piegzik forcefully challenges established Western narratives surrounding this critical engagement in the Pacific War.

Operation MO, the Japanese plan to seize Port Moresby, kicked off in early May 1942. By committing three carriers, including the famous Shōkaku and Zuikaku, the Nippon Kaigun’s command risked a critical part of their fleet just before the envisaged decisive battle at Midway in the Central Pacific, scheduled for early July. The operation was considered a vital part of Japanese strategy. Victory would isolate Australia and New Zealand and extend access to vital resources crucial to Japan’s war effort. Victory, however, would prove elusive after American codebreakers deciphered Japanese radio traffic that revealed their plans in the weeks leading up to the launch of Operation MO.

Using this intelligence to their advantage, U.S forces located elements of the Japanese navy as they steamed through the Coral Sea. Soon after, history’s first carrier battle began. Piegzik combines expertise in military history with mastery of the Japanese language to provide a rare perspective on the Imperial Japanese Navy’s operational choices during the battle. His use of Japanese archival documents and personal testimonies from surviving Japanese crew members uncovers new dimensions to the battle. The clash proved to be a Pyrrhic victory for the Japanese, who sunk the Lexington and crippled the Yorktown but were forced to call off Operation MO due to the severe damage inflicted on Shōkaku and the heavy losses among their aircrews.

Revealed here are the circumstances and actual reasons for the Japanese failure and the revised impact of the Battle of the Coral Sea on the Battle of Midway. Beyond tactical details, Piegzik offers insight into the broader consequences of the battle. He engages with sources previously underexplored and integrates them with Allied perspectives to ensure a well-rounded understanding of the events. A vital addition to any World War II collection, Gamble in the Coral Sea offers a nuanced and thorough exploration of a battle that significantly shaped the trajectory of the war in the Pacific.

[C. G. Telcontar · Rating 3 out of 5]

It's ok if belabored by the author's tiresome use of the phrase MO Kido Butai because he learned Japanese and wants to show off his skills. Switching between Imperial and metric units for the two opposing sides sounds good until you have to do the mental gymnastics when both sides are engaged against each other. I did learn a few things about this battle considered from the IJN side but found the overall tone a bit pretentious and unnatural. The author's just not certain of himself and it drags down the narrative. The final chapter of what ifs is unhelpful if not quite an eye roller. As a final broadside, his insistence in aping the term DECISIVE BATTLE because the IJN used it is obnoxious in the extreme. He overdoses on the phrase throughout the text until it overwhelms the story. This book needed another draft and a stern in house editor and I'm disappointed in that aspect because it's published by Naval institute Press. Of all publishers -- they need to crack the whip to keep authors on the straight and narrow.

Could have been far better.

Japanese mindset Coral Sea

This book gave me fresh insights to the Battle of the Coral Sea. I feel like I have an idea as to what was going through the Japanese minds. Well written. He make it easy to follow each step of the battle.

This history of the battle of the Coral Sea was written by a Polish author who made the effort to learn Japanese and consequently could study Japanese primary and secondary sources, providing a very useful complement to the existing accounts of the battle, which are primarily based on American sources.

Nearly all battles in history are confusing, but this one was more so than most, because both sides made a series of mistakes and repeatedly missed opportunities. Because the “fog of war” was so dense, and it is necessary to keep track both of what was actually happening and what the protagonists believed was happening, it is not on easy event to give a coherent account of. I find that the author succeeds reasonably well, but not as well as some of his precursors. Perhaps also because he injects a lot more detail, which helps to set the record straight but can make the flow of events harder to follow. Also, although his skill of writing in English is good overall, he does make grammatical mistakes (such as the frequently inappropriate use of "the") that can make sentences confusing. A read-through and correction by a good editor would have been very useful.

That said, reading the Japanese perspective on the battle does change one's understanding of it, and in that regard the book is a success. It does belong on a recommended reading list of Pacific War books.

At its end, the author asks what went wrong for the Imperial Japanese navy, and answers his own question with "everything". That may be fair enough, but what strikes me most is that although the Japanese deployed a surprising range of assets on reconnaissance missions, they failed to obtain reliable information on their enemy. It is remarkable that despite establishing seaplane bases of Tulagi and Deboyne, having land-based bombers at Rabaul, deploying seaplanes from cruisers and seaplane tenders, and sending aircraft from the carriers on scouting missions, the Japanese didn’t manage to pinpoint the location of the US Navy carriers until it was too late. It was not from a lack of trying, and not for a lack of sighting reports, but from an inability to give a sound interpretation to the stream of intelligence that came in. Some of which, admittedly, was wrong. It needs to be conceded that at this stage, American intelligence wasn’t functioning much better. Still, the IJN’s neglect of operational intelligence was notorious and the overly complex command structure that they adopted for the “MO Operation” did not help.

Informative as this book is, I would recommend to read Stern’s “Scratch one Flattop” first. Not because the US perspective is more important, but because Stern gives information on structural factors, such the geography of the region, that make the overall story easier to understand. And then make sure to get access to this side of the story too.

Pierwsze, co przyszło mi do głowy po przeczytaniu tej książki, to fakt, że jest ona wręcz kwintesencją literatury historycznej. Nie spodziewałem się aż tak szczegółowego przytaczania mało znanych faktów — zwłaszcza że historia II wojny światowej nigdy nie była obszarem moich szczególnych zainteresowań. Ich ogrom momentami potrafi lekko przytłoczyć, ale paradoksalnie nie wpływa negatywnie na odbiór całości.

„Bitwę na Morzu Koralowym” czyta się szybko i z autentycznym zainteresowaniem, tym bardziej że autor przedstawia wydarzenia przede wszystkim z perspektywy Japonii, a nie Stanów Zjednoczonych i ich sprzymierzeńców. To podejście nadaje opowieści świeżości i pozwala spojrzeć na konflikt z zupełnie innej strony — na Zachodzie raczej rzadko eksponowanej.

Sam opis bitwy okazuje się fascynujący. Było to przecież jedno z kluczowych starć wojny na Pacyfiku i pierwsza w historii potyczka lotniskowców. Autor szczegółowo pokazuje, dlaczego wojska Nipponu odniosły jedynie pyrrusowe zwycięstwo, a jednocześnie uświadamia, jak niewiele brakowało, by historia potoczyła się zupełnie inaczej. Strategicznie Japonia poniosła jednak porażkę, która później wpłynęła na losy znacznie większej bitwy o Midway.

Największym atutem tej pracy pozostaje unikalna perspektywa i ogrom wykonanej pracy badawczej. Widać, że autor nie tylko przeprowadził imponujący research, ale też przez lata zgłębiał temat w Japonii. Dawno nie czytałem książki aż tak nasyconej faktami, a jednocześnie napisanej w sposób angażujący.

Na plus działa również to, że autor nie próbuje nikomu kibicować ani moralizować. Zachowuje dystans i skupia się na możliwie rzetelnym przedstawieniu wydarzeń. Książka całkowicie zaspokoiła mój głód tego typu historii i dała mi dobre wyobrażenie o tym, czego można spodziewać się po „czarnej” serii wydawnictwa.

To było bardzo ciekawe doświadczenie — zupełnie inne niż literatura, po którą sięgam na co dzień. Na razie jednak wracam do fikcji. Mimo to książkę zdecydowanie polecam, bo trudno odmówić jej rzetelności, fachowości i imponującego wyczerpania tematu.

I'm not good at writing reviews, especially in english. However, I have "a bit" of knowledge of WW2 naval warfare. Everything has been written about the Pacific theater of operations (PTO) from an American perspective. New findings are quite rare. However, there's a huge gap when it comes to the Japanese perspective. This is where Gamble in the Coral Sea has virtually no competition.
So if you are looking for a large dose of fresh knowledge, this book delivers. Oh boy, it delivers with a solid punch. I can't remember the last time I learned so much new. Chapters about IJN are fantastic! With all due respect, the last work to include such amount of the Japanese perspective, is probably Shattered Sword.

In my humble opinion, Gamble in the Coral Sea is excellent. The number of myths Michał Piegzik quietly dispels, is significant. But he does so skillfully. Did Japanese aircraft carriers exchange planes? Yes. Did the Japanese search for downed pilots? Yes. Were they aware of their own limitations? Yes. These are just a few examples. If you think you know "everything" about PTO, you'll be surprised when you read Gamble in the Coral Sea:)

It's clear that the Author relied extensively on Japanese source documents. This is where the book is truly exceptional. The American perspective is also presented. The content, as a whole, is chronologically arranged, coherent and very interesting. My perception of this battle is different now.

I strongly recomend this book. I think it is a gamechanger. It is fresh. It is unique. Finally, it is a pleasant read. Would I read it again? I will, no doubt

My hobby is WW2 in the Pacific, therefore I was looking forward to read Piegzik's book. I expected something extraordinary and this is exactly what I got.

Book is based on Japanese resources, which is the biggest advantage. By resources I don't mean Senshi Sōsho, but particularly primary documents from JACAR archives. Also there are numerous quotes of Japanese participants of the battle, which make reading a real pleasure.

Book is pleasant to read and stuffed with precise knowledge. The biggest impression for me was the chapter about Japanese search missions (and decisions linked with them) on 7th May. It's hard to find any book that describes the matter in such detailed way (especially from Japanese POV). I wasn't aware of so many matters regarding search missions. Author describes them splendidly.

Detailed crew roster of Japanese carriers must be highly valued. Meticulous work by Piegzik there too.

In general, even though I had some knowledge about the Battle of Coral Sea, the book reveals lot of new stories about the clash. Especially form Japanese side. Therefore I rate the book 5/5. For me is a "Shattered Sword" kind of book: revealing, gripping, eye-opening and educational.

I genuinely enjoyed Gamble in the Coral Sea. I'm not a historian, but I've read other books about WWII in the Pacific theater, and I greatly appreciate this book's unique, in-depth look at the Japanese perspective. It provides excellent detail on the strategic thinking from the Imperial Japanese Navy, complementing and enriching the accounts from American historians.
As a history hobbyist, I found the book compelling and highly engaging. If you want a counter-balance to the standard histories of the Pacific War, this is an excellent choice.

Detailed, well written book about the battle of Coral Sea in early May 1942. The author has done extensive research into this history from Japanese historical sources, and presents an excellent view of the first carrier battle of the war.

Fantastic and insightful work.
