Empire of Ashes: Truman, Hirohito, and the Descent into Total War

by James M. Scott

From the acclaimed Pacific War historian, the harrowing story of America’s bombings of Hiroshima and Nagasaki in the dramatic struggle to end World War II.


Over three days in August 1945, a nation once morally opposed to the bombing of civilians killed 120,000 men, women, and children; doomed tens of thousands more to agonizing death in the weeks and months ahead; and annihilated two Hiroshima and Nagasaki. Empire of Ashes explores the final brutal months of the war in the Pacific, featuring the voices of never-before-heard victims of the atomic bombs. Through interviews with survivors and accounts gleaned from Japanese sources, New York Times best-selling author James M. Scott combines the attacks’ heart-wrenching details with their causes and consequences, from debates within the Manhattan Project at Los Alamos, Oakridge, and Hanford to the fallout that would alter decades of life in Japan. From “an exceptional writer with a keen eye for dazzling detail and gripping, suspenseful storytelling” (Henry Richard Maar III, Journal of Military History), Empire of Ashes illuminates the moral dilemma at the center of America’s decision to inflict total war upon Japan with startling immediacy.

This was really well written history, not exactly as prosaic as Eric Larson, but much more so than a history textbook. The quotes all feel like part of a natural conversation and even the scientific explanations do not overwhelm the reader.

As far as the content, so much of it seems like a tragedy that the Japanese could have avoided. What I did not know was that after the 2nd bomb was dropped, there was an attempted coup by Japanese officers to continue the war and keep fighting. If you only have a cursory knowledge of the end of World War II, this book does a great job of putting everything into context, including all of the debate about whether or not the US should have used the bomb.

The challenges in narrative nonfiction are you’re either telling a well-known story, which makes it tough to keep the reader engaged, or you’re telling a story that isn’t known at all, which makes it difficult to capture the reader early. As a writer, climbing those hills requires a deft combination of skill and talent. If you bog the reader down with details when he already knows the ending, you risk having him skim and drift, turning pages while half-listening to Ella Langley in the background. If you’re introducing the reader to new characters and a drama he doesn’t know, you better keep it moving and make it a page-turner. Otherwise, the reader opens Wikipedia and closes your book.

In his three books on the Secord World War in the Pacific, James Scott answered the call on both of those tasks with the kind of discipline and talent that made it seem effortless. His latest, EMPIRE OF ASHES: TRUMAN, HIROHITO, AND THE DESCENT INTO TOTAL WAR, is one of the most riveting accounts of the final months of the War ever written, which is amazing given the hundreds of books and films covering every jot and tiddle of that time period. Scott does this by achieving the ultimate goal for every author: his pacing, plot, detail, and character development make you forget you’re reading. Within a few pages you’re so engrossed in a story you have known your entire life that you can’t put it down and the world around you goes quiet.

Relying on so many sources that his notes and bibliography encompass 82 pages, Scott weaves in enough biographical and sociological detail to put you in the minds of men like General Curtis LeMay, General Leslie Groves, President Harry Truman, as well as Geneal Tojo, Emperor Hirohito, and Defense Minister Anami.

Since there are no plots to spoil, the book opens in Warm Springs, Georgia where Franklin Roosevelt sat for a portrait in the quaint quarters known as the Little White House. As an aside, it was Roosevelt’s uncle Teddy who first called the Executive Mansion in Washington the White House, and Franklin was the first to extend that title to an off-site location. In the sitting room where a fussy assistant and artist waited on the President, Roosevelt didn’t seem himself. A couple of minutes into the session, he put his hand to his head and complained of not feeling well. Within minutes he was unconscious and died soon after.

Truman was everything Roosevelt wasn’t – hardscrabble, direct, unworldly, and poor, the kind of guy who preferred cold cuts to caviar and who expected you to get right to the point in every conversation. How that sudden personality change effected the culture in Washington and the world is a big part of Scott’s book.

Also, Scott captures the disconnect – which continues to this day – between Eastern and Western values, traditions, philosophies, and priorities. For example, right now, in 2026 with the world smaller and more connected than ever, trying to explain “face” to the average Missourian is like asking him to, well, build an atomic bomb. That cultural chasm played a huge role in the debates and decisions that lead to Little Boy being dropped on Hiroshima. And for those armchair generals who still can’t believe the U.S. did such a thing, keep in mind that even after LeMay’s firebombing left Japan on the brink of starvation, Anami had amassed almost 900,000 troops to repel the expected U.S. invasion, and citizens were being ordered to craft spears out of bamboo to fight to the last man, woman, and child. Even after the second bomb hit Nagasaki, Anami wanted to keep fighting. There was even a brief coup attempt at the Royal Palace in Tokyo by pro-war advocates.

Scott covers all this and much more with an elegant prose that moves like the most compelling epic you’ve ever seen. I cannot recommend this book enough.

Yes, you know the ending – you even know the biographies of most of the characters – but EMPIRE OF ASHES is still a must-read for all the right reasons.

When President Franklin Roosevelt died suddenly on April 12, 1945, Vice President Harry Truman was suddenly thrust into the spotlight as the leader of the United States. Little did he know that a secret project was nearing completion, a project which would define his Presidency and his legacy. This project, known as the Manhattan Project, was the ultra-secret project carried out at three different sites in the United States to manufacture an atomic bomb.

Beginning with President Roosevelt's last few days, author Scott has written another excellent book, this time recounting the development of the atomic bomb and the momentous decision to ultimately use it against Japan, followed by the tense following days as Japan wavered on surrender. The book starts with Truman becoming President and his crash education in what his new job entailed, from dealing with the war with Japan, meeting foreign leaders and deciding the future of Europe, to deciding to use the atomic bombs in the hopes they'd end the war. Along the way the reader is given a front row seat in the Oval Office as Truman juggles one hot potato after another. There is also is a view into what was going on with his counterpart in Japan: Emperor Hirohito. While slowly watching his country being burned to the ground and his people starved, Hirohito chooses not to interfere with the running of the war, instead relying on others to come up with ways to win the war. An impending invasion by American forces captures the focus of the Japanese military, with plans to wage a war of attrition being their primary answer. Whether or not this was a realistic solution is not the focus of the book, but concerns about the cost of such an invasion play prominently in Truman's decision to ultimately use the atomic bombs.

The two missions in which the bombs were dropped on Hiroshima and Nagasaki are covered in really good detail, and provide a stark contrast in their execution. The mission to Hiroshima went virtually by the book and was executed flawlessly, while the mission to Nagasaki was beset with difficulties before it even left the ground. Things didn't get better once they took to the air, but they were ultimately able to get the job done. The aftermath of the two bombings as experienced by witnesses and victims on the ground is recounted in very graphic detail and leads to the final stretch run leading up to Japan's surrender. There are lots of moving pieces in the Japanese hierarchy, all trying to win support for either ending or continuing the war, and this leads to a bitter struggle between doing one's duty to the Emperor or following the Samurai code and fighting to the end.

Since I've never read much on the Manhattan Project, the book was a great way to find out more about one of the greatest secret projects in American history. While the use of the bombs is viewed by many in our modern times as an atrocity and/or war crime, there were objections and concerns back in 1945 as well. The author does a great job of presenting much of the back and forth discussions and protests over using the bombs, but he ultimately leaves it up to the reader to make their own decision about the morality of using the bombs.

Starting with his book on the famed Doolittle Raid on Japan and followed by a book on the firebombing of Japan by American planes, this book completes author Scott's trilogy on the bombing of Japan during World War II, and it's a fitting conclusion. I highly recommend this book along with it's two preceding volumes.

Many thanks to W.W. Norton & Company, along with NetGalley, for providing me with an ARC of this book.

I have a weird hesitation before I start James M. Scott's books. There are thicker books while there are others which are going to be more emotionally fraught. It's not either of those things, but rather that I know his books end up so immersive that I need to be in the right headspace to fully enjoy them. I don't want to be distracted or rushed. I know I am going to love them, but I want to be able to experience them fully. This is especially true for Empire of Ashes as it is (what I assume to be) Scott's last book on the Pacific Theater of World War II. I've been on this ride since his Rampage, and I wanted him to stick the landing. As always, any concerns or hesitations I had were not well-founded.

Even people who don't read World War II literature should be somewhat aware of the setup. FDR has died, Truman is taking over, and Hirohito is the last of the Axis powers. The U.S. is about ready to invade the Japanese Home Islands and a bloodletting never before seen is about to commence. Then, an alternative emerges after hiding in the shadows. Well, perhaps I should say two alternatives: Fat Man and Little Boy.

Yes, everyone had to read everything above in school ad nauseam. I wouldn't recommend anything to you that didn't bring something new to the table. Scott is all about the humans at the center of the drama. Truman gets the most attention, but Hirohito is put into focus as well. Most importantly, Scott illustrates just how horribly dysfunctional Japan's government was at the end of the war (Side note: The perfect complement to Scott's book is Evan Thomas' Road to Surrender which gets into the minute details of Japan's hopelessly disordered decision making). Scott has a lot of ground to cover, but by being character-driven, he doesn't need the nitty gritty of every decision. You don't have to spend dozens of pages on Truman's decision to drop the bomb when you've already thoroughly explained who this man was and how he thought about everything.

When Scott does step away from the characters, his visceral writing gets to shine through. His description of what happened when the bombs were dropped will not soon to be out of my mind. As for whether dropping the bombs was the right thing to do, well I firmly believe no book will ever be able to convince everyone one way or another. Instead, we get great books like this one.

I recently had the opportunity to read the upcoming "Empire of Ashes: Truman, Hirohito, and the Descent Into Total War," by James M. Scott, being published by W.W. Norton & Company. I am working from an ARC which they have graciously provided me with for review purposes. Let me first observe that the period of time covered by the book is roughly centered on the days between the death of FDR and the surrender of Imperial Japan in the Pacific theater of war. This is not to say that the author works without reference to the overall context of those events; where necessary, he carefully covers events that predate F.D.R.'s death and the Japanese surrender but which are germane to his thematic concerns, aptly set forth in his subtitle. His principle concern is with the development of a framework within which the operational deployment of atomic weapons could become the official policy of the United States of America. His writing is character driven and often illustrated by illuminating anecdotes which serve to place the principal actors in the narrative in sharp relief. For the reader who has immersed him or herself in the existing historiography of this period, there will be little here that adds to what we already know, but for the reader who may not have looked upon these dramatic events and their context in any sort of depth, this is likely to be quite rewarding. I would recommend it for all general collections as a good starting point for an understanding of the controversies swirling around the use of the nuclear bomb and the potential options and consequences associated with it. The writing is good, and because of its human focus, it is useful as a tool to try to bring existential issues into relief against the background of a world war and the struggle to bring it to a conclusion.

[Gavin Mattiace · Rating 5 out of 5]

James Scott has produced a very personal telling of the end of the war in the Pacific. His focus on the character and personality of President Truman and Emperor Hirohito puts on full display the magnitude of the decisions being made, and the respect that each of the major players had for the consequences of their actions. The conflict between the Emperor and the military leadership of Japan is brought into stark contrast with the reality that Japan faced annihilation as a society in the summer of 1945. Meanwhile, the scientists working with the Manhattan Project and the military leaders facilitating it and preparing for its eventual culmination at Hiroshima and Nagasaki are presented alongside their honest opinions as to what the correct action with such a weapon should be.

Overall, a fantastic read and a powerful culmination of what has fast become one of the best series on the Second World War. This book reads as a natural conclusion to the work conducted in Target Tokyo: Jimmy Doolittle and the Raid That Avenged Pearl Harbor and Black Snow: Curtis LeMay, the Firebombing of Tokyo, and the Road to the Atomic Bomb. A must-add to any true student of history, leadership, or warfare.

[Sean Keating · Rating 5 out of 5]

Excellent written book. Adds a lot to the World War II history. As a person who is read many World War II history books this added some additional new information.
The Japanese military controlled Japanese society rationing everything. Japan needed to import every raw material and food.
The book explains the development of the atomic bomb, including the three separate Seitz, Oak Ridge, Los Alamos, New Mexico and Hanford engineering works in Washington. It also details all of the involved scientist.
Importantly, there was significant committees developed throughout the government to decide on how to use this new weapon. There was the advisory committee on uranium which advised the White House, target committee intern committee.
There was significant debate on the morality of the weapon.
The Potsdam declaration was a warning to Japan before the bomb was dropped. The goal of this proclamation was to confirm the unconditional surrender required.
Detailed explanation of the flight and bombing of Hiroshima with the outcome as well as the bombing of Nagasaki. Interesting the second bomb was planned to be dropped on Kokura, but due to weather during the flight it had to be changed to Nagasaki.
After the bombing, there was quite a bit of difficulty in convincing all of the military leaders and political leaders to accept the surrender proposal. It led to an attempted military coupe, which eventually failed.

Empire of Ashes: Truman, Hirohito, and the Descent into Total War by James M. Scott examines the final, devastating months of World War II in the Pacific and the decisions that led to the atomic bombings of Hiroshima and Nagasaki. Scott follows two central figures, U.S. President Harry Truman and Japan’s Emperor Hirohito, as they faced enormous pressure to bring the war to an end. He explains the political and military debates in Washington and Tokyo, showing how American leaders weighed the terrible consequences of using atomic weapons against the possibility of an even bloodier invasion of Japan. At the same time, Japanese military leaders remained determined to continue fighting, even as American bombing campaigns destroyed cities and caused immense civilian suffering. The book also takes readers inside the development of the atomic bomb and gives particular attention to the ordinary Japanese people who experienced its horrifying effects. Through survivor accounts, Japanese sources, and American records, Scott connects the bombing of Hiroshima and Nagasaki to the larger story of total war, Japanese resistance, and the eventual surrender. Rather than presenting the bombings as a simple military decision, the book explores the moral uncertainty surrounding them and asks what nations are willing to sacrifice in order to achieve victory.

ARC from NetGalley

A very well written and absorbing general account of the final days of the Pacific War and the atomic bombings of Japan. There has certainly already been plenty published on this topic, but Scott delivers a very readable synthesis of multiple perspectives. He jumps back and forth smoothly between Truman's decision making, the effort involved in the creation of the atomic bomb, the Japanese government, and individuals waging and suffering the war. There are better books about individual aspects of this story -- The Making of the Atomic Bomb by Richard Rhodes is one of my all time favorite books, for example -- but Scott does a great job covering nearly all the angles in satisfying detail. I would have liked a little bit more engagement with historiography and moral debates, particularly with something as fraught as nuclear war, but I understand that's never going to be the focus of what's ultimately a popular history book.

One small complaint: the subtitle is bad. There was no "descent into total war" in 1945. We were deep into total war well before then.

Empire of Ashes is a powerful and deeply absorbing account of the final months of World War II and the decisions that led to the atomic bombings of Hiroshima and Nagasaki.

What stood out to me most was how James M. Scott makes history feel personal. Rather than simply presenting dates and military decisions, he brings figures like Truman and Hirohito to life while also giving attention to the scientists, soldiers, political leaders, and ordinary civilians caught in the consequences of war.

The sections covering Hiroshima and Nagasaki are especially difficult to read, but they are important. Scott doesn't shy away from the human cost or from the moral questions surrounding the decision to use the bombs. I also found the political and military struggle within Japan, including the attempt to prevent surrender, particularly fascinating.

The writing is detailed without feeling like a textbook, and the storytelling keeps the book moving despite the seriousness of the subject. Whether you already know the history or are learning about it for the first time, this book gives you plenty to think about.

[Philip Kuhn · Rating 4 out of 5]

A really good book on the end of the Pacific War, I learned a few things and enjoyed it.
Good first part of the book on FDR and how sick he really was. Good treatment of the life and rise to power of Truman. I liked the coverage of the Manhattan Project and General Groves.

Scott did a great job with the horror of the aftermath of the atomic bomb attacks. It was really horrible stuff and he didn't sugar coat it for you, like people wandering around in a daze with their skin burned off. It needed to be said.
Also a good account of the Japanese officers attempted coup that would have been incredibly tragic had it succeeded and the war continued.
Good book

Usually, Total War embraces a journey along historical highways and the atomic destination that ended World War II and ushered in the nuclear era. * How Scott balances historical leanings with the outcomes, but without resorting to a three-volume history, ensures Total War is recommended reading.
