Reviewed by Darren Puttock
The Battle of the Coral Sea (4-8 May 1942) occupies a unique place in naval history as the first major sea battle where the opposing naval forces never sighted one another. It has also long been overshadowed by the Battle of Midway (4-6 June 1942), and the dedicated historiography of Coral Sea remains surprisingly small. For decades the battle was interpreted through larger works on the Pacific theatre, carrier aviation, or as part of official histories. This includes valuable and influential works by Samuel E. Morison, G. Hermon Gill, Edwin P. Hoyt, Chris Coulthard-Clark, and John B. Lundstrom. Recent scholarship continues to improve our understanding, including Mark Stille’s concise campaign study The Coral Sea 1942 and Robert C. Stern’s Scratch One Flattop which stood as the most substantial English-language monograph before Gamble in the Coral Sea. Michał Piegzik’s distinctive contribution is his extensive use of Japanese primary sources, thus making Gamble in the Coral Seaone of the most important contributions to the Coral Sea historiography in recent decades.
In May 1942 the Japanese planned Operation MO, the seizure of Port Moresby through amphibious assault, and sent several task forces to the Coral Sea. Operation MO was part of the broader Japanese strategy to isolate Australia by threatening its sea lines of communication, thereby limiting its ability to support Allied forces and operations. Although the Japanese sank the fleet carrier USS Lexington, the tanker Neosho and the destroyer USS Sims, they ultimately failed to achieve their operational objectives. The Japanese light carrier Shōhō was sunk, and both fleet carriers Shōkaku and Zuikaku were rendered combat ineffective and unavailable for their planned participation in Midway a month later. Since the war, historians have generally characterised Coral Sea as a Japanese tactical victory but an Allied strategic victory, and this interpretation largely continues to anchor discussion and analysis of the battle.
Michał Piegzik is an expert Japanese linguist with a keen interest in the Battle of the Coral Sea, and as such all those interested in the Pacific Theatre during the Second World War stand to profit from his desire to tell the story from the Japanese side. Through extensive use of Japanese primary sources, including the official Japanese military history Senshi Sōsho, Piegzik provides us a perspective that has remained largely unexplored. He is clear in his ambition: to reassess the Fourth Fleet’s plan to seize Port Moresby, find the most critical mistakes made by the Japanese, and consider lessons the Japanese Navy could have learned before the Battle of Midway.
Piegzik’s extensive use of original Japanese naval terminology is one of the book’s distinguishing strengths, reflecting his commitment to presenting the campaign from the Japanese perspective rather than filtering it through a traditional Anglo-American narrative. As a result, readers should be prepared to learn Japanese terms with which they are almost certainly unfamiliar. While these are all translated on first use and the book includes some reference material, they may initially prove challenging for readers unfamiliar with Imperial Japanese Navy terminology. Given the frequency with which terms such as shōtai, buntaichō, kankō, and hikōtaichō appear throughout the text, a consolidated glossary would have significantly improved the book’s accessibility without diminishing scholarly rigour. This minor editorial omission should not dissuade readers, however, as the terminology quickly becomes familiar with only a modest amount of effort.
Australian readers seeking Allied-centric analysis and reassessment of Rear Admiral Crace’s Australian-American Task Group 17.3, formerly Task Force 44, should note the book’s principal contribution lies elsewhere. This means readers can expect much richer Japanese context, such as Japanese, planning, reconnaissance, operational decision-making and strike execution; the scope of exaggeration of the success of the attacks; and how false reports of battleships and cruisers sunk or damaged affected the Japanese operational picture. Readers acquainted with the existing historiography are unlikely to have their perspective of Crace’s mission to the Jomard Passage fundamentally changed, but they will be richly rewarded with a much fuller appreciation of the Japanese operational context within which his task group operated.
Piegzik’s history is not a revisionist one in terms of seeking to overturn our understanding of Coral Sea, as those who are familiar with the battle will finish Gamble in the Coral Sea recognising it as the one they’ve always known; however, this book’s truly unique contribution to the scholarship is the ability to finally see the Battle of the Coral Sea through Japanese eyes. Rather than serving as the faceless adversary in an Allied narrative of the Coral Sea, the Imperial Japanese Navy emerges in Piegzik’s book as a complex organisation of capable but fallible officers and sailors. They, like the Allies, were grappling with uncertainty, institutional constraints, miscommunication, and the cumulative consequences of operational errors. This was Piegzik’s goal, and in this reviewer’s opinion he has certainly succeeded.
Much of this humanisation of the Japanese comes through Piegzik’s engaging narrative style. The book has too many examples to include them all in this review, though the dusk attack by the Japanese on 7 May 1942 was chosen by this reviewer as a poignant example. Admiral Chūichi Hara decided to launch an attack late on 7 May to seek out the Task Force 17 carriers, largely underpinned by the loss of the Shōhō and increasing feelings of desperation to engage the Allied carriers. After receiving an updated contact report, the Air Officer on Zuikaku, Lieutenant Commander Takeshi Mieno, calculated the attack would take place at dusk due to the distances involved, and was not keen to risk the pilots returning in the dark as many were not trained to do so. In the end, Hara’s chief of staff Commander Mineo Yamaoka argued convincingly for a strike, and the attack proceeded. Of note, earlier in the book Piegzik reveals Yamaoka was “known for his stubborn and persuasive personality,” making it easier to imagine the dramatic scene on Zuikaku.
In the end, Mieno’s worst fears were realised. The strike group could not find the carriers and were instead found by Wildcatfighters from Task Force 17, who shot down seven Kate torpedo bombers and one Val dive bomber. Worse, Piegzik notes, the interception caused the remaining aircraft to scatter and escape into the clouds. It was soon after, once the mission began to unravel and their ordnance had been dropped, that the surviving Japanese planes spotted Task Force 17. This also led to the incident most recounted in Allied narratives when several Japanese aircraft mistook Yorktown for their carrier and made a landing approach. Veering off at the last second in sudden realisation of their error, this was indeed a notable incident. For the Japanese, Piegzik tells us, it was only one misfortune in a series during the failed attack. He tells of the agony on board Zuikaku as they awaited the return of Lieutenant Commander Shigekazu Shimazaki and his planes, and the sincere, heartfelt apology of Commander Hisao Shimoda, Zuikaku’s Flight Officer, when he told one of the recovered pilots “I am terribly sorry. We sent you all to die, I am so sorry. Please rest now.” This attack is often noted in Allied literature as a reckless waste of experienced men and valuable aircraft. Piegzik is also critical of the decision in his analysis, but he explains it with his insights into the struggles of the men working under relentless pressure from higher headquarters, the fog of war, and peer pressure within the Japanese military system. It is this kind of perspective that makes Gamble in the Coral Sea so valuable to the historiography.
One of the more curious aspects of Gamble in the Coral Sea is Piegzik’s final analysis of the battle titled “What Failed on the Japanese Side?” Piegzik notes “[T]he Battle of the Coral Sea was a Pyrrhic victory for Japan,” and then proceeds to tell us “almost everything” went wrong for the Japanese: operational planning failures, reconnaissance failures, command failures, organisational failures, misuse of Shōhō, poor allocation of forces, poor coordination, and so on. The end result of the Coral Sea was that Shōhōwas sunk, Shōkaku was severely damaged and incapable of flight operations, and Zuikaku’s air losses were so great she was rendered combat ineffective. Operation MO was cancelled, and the Japanese limped home from the Coral Sea with their operational objectives unachieved and two fewer fleet carriers available for the upcoming Operation MI at Midway. Piegzik’s characterisation of the battle as a Pyrrhic victory for Japan sits somewhat uneasily alongside the extensive evidence presented throughout his analysis, though it remains broadly consistent with the prevailing historiography that labels Coral Sea a tactical Japanese victory but Allied strategic victory. Though it was not Piegzik’s stated goal to challenge this view established by Samuel E. Morison’s official history shortly after the war, in this reviewer’s opinion this represents a lost opportunity for him to challenge this long-held belief through his own outstanding scholarship based on his meticulous research of Japanese sources.
Debates over the outcome of Coral Sea aside, Gamble in the Coral Sea is a highly valuable piece of scholarship and it will come as little surprise this reviewer thoroughly commends this work. Piegzik’s greatest contribution is not that he overturns any existing interpretations of Coral Sea, but that he fundamentally broadens the evidentiary base and understanding on which future interpretations of the battle will be built. Gamble in the Coral Sea is immediately one of the most important monographs on the Coral Sea, and a must-have for anyone interested in the war in the Pacific in general and Battle of the Coral Sea in particular.
