The best books about hidden stories of World War II that make you wonder: “what if?”

Why am I passionate about this?

Imagine World War II—with frequent chemical warfare attacks on cities and battlefields. Before and during World War II, laypeople and leaders held the widespread conviction that poison gas would be used in the next big war more destructively than in World War I. Churchill considered using gas if Germany invaded Britain. Roosevelt promised retaliation if the Axis used gas. Canada tested gas in Alberta’s fields. Fear and preparation for gas attacks permeated multiple countries, from laypeople to the top, from civilians to the military, but few talk about it. This is a hidden story of World War II, but one worth knowing. Just the threat of gas influenced the conflict.

Book cover of Holding Their Breath: How the Allies Confronted the Threat of Chemical Warfare in World War II

What is my book about?

Since I learned Hannibal crossed the Alps with elephants to attack the Romans, I’ve been fascinated by past conflicts. Now, I’m a professional military historian.

Wars generate devastation and cruelty, but they also inspire creativity and resilience. It’s eye-opening to go behind the scenes of an event to discover the details and the critical turning points. So, these are five of my favorite books that reveal hidden events, decisions, and people during World War II. Reading them made me say, “I never knew that!” and “What if one decision had been different?”  I hope they make you wonder as much as they did me.

The books I picked & why

Book cover of Operation Mincemeat: How a Dead Man and a Bizarre Plan Fooled the Nazis and Assured an Allied Victory

M. Girard Dorsey Why did I love this book?

This is one of the most tricky, macabre, and yet human deception plans in World War II. The sheer cleverness involved as an Allied team, including James Bond creator Ian Fleming, created a pretend Marine, fake invasion plans, and a non-existent crash as part of an operation to trick the Germans reads like fiction.

The gamble had real-life consequences. If the operation had failed, the invasion of Sicily would have cost many more Allied lives and probably delayed the end of the war. While there have been older accounts of the events, Ben McIntyre is a talented and credible journalist and historian who often focuses on tales of espionage. Every time I read this one, I wonder:  How did they pull that deception off?

Book cover of Lethal Tides: Mary Sears and the Marine Scientists Who Helped Win World War II

M. Girard Dorsey Why did I love this book?

What an eye-opening biography! Mary Sears never left the United States, but she was a key reason the World War II Pacific invasions were successful. This book does not take away from the sacrifices of the fighters or the hard strategic decisions and leadership of the commanders. It does show what science, combined with traditional fieldwork and creative library research, can do to design maps and provide information about tides, ocean depths, and coral reefs, thus enabling men, ships, and equipment to attack Japanese-held islands effectively.

This book is also an homage to teamwork by people, especially women and academics in the 1940s, who didn’t always receive a lot of respect from the military at the start of the war yet found themselves relied upon repeatedly for their top-secret work.

What is this book about?

"Magnificently researched, brilliantly written, Lethal Tides is immensely entertaining and reads like an action novel. Catherine Musemeche has brought to life the incredible work of the scientists and researchers who made such a remarkable contribution to America's war effort in the Pacific theater during WWII." -Admiral William H. McRaven (U.S. Navy, Ret.), #1 New York Times bestselling author of Make Your Bed and The Hero Code

Lethal Tides tells the story of the virtually unknown Mary Sears, "the first oceanographer of the Navy," whose groundbreaking oceanographic research led the U.S. to victory in the Pacific theater during World War II.…


Book cover of The Great Escape

M. Girard Dorsey Why did I love this book?

This is the story of Allied POWs who dug escape tunnel after escape tunnel. Simultaneously, they plotted to drive their captors crazy while stealthily equipping successful escapees to evade the enemy as they fled across hostile territory. Although the story has been told several times, including in a movie with the same name, this version was written by a journalist who had been in the camp.

The book is alternately laugh-out-loud funny to awe-inspiring, heroic to tragic. While entertaining, it also raises questions about human strengths and weaknesses. What would you do in the same situation? This has been one of my favorite books since I first read it.

What is this book about?

They were American and British air force officers in a German prison camp. With only their bare hands and the crudest of homemade tools, they sank shafts, forged passports, faked weapons, and tailored German uniforms and civilian clothes. They developed a fantastic security system to protect themselves from German surveillance.

It was a split-second operation as delicate and as deadly as a time bomb. It demanded the concentrated devotion and vigilance of more than six hundred men-every one of them, every minute, every hour, every day and night for more than a year.

Book cover of Japan 1941: Countdown to Infamy

M. Girard Dorsey Why did I love this book?

The author does not pull any punches. She investigates the Japanese path to the Pearl Harbor attack, from cultural constraints that made it challenging to resist the drift to war to personality assessments that help make sense of the decisions to strike the US, even when war games demonstrated that the country could not win a confrontation.

Despite knowing the outcome of the attack, the story is so well told that delving into the steps toward conflict is engrossing. The book makes you wonder: What might have stopped the attack? If we knew then what we know now, would the attack at Pearl Harbor have been a surprise?  

By Eri Hotta,

Why should I read it?

2 authors picked Japan 1941 as one of their favorite books, and they share why you should read it.

What is this book about?

A groundbreaking history that considers the attack on Pearl Harbor from the Japanese perspective and is certain to revolutionize how we think of the war in the Pacific.

When Japan launched hostilities against the United States in 1941, argues Eri Hotta, its leaders, in large part, understood they were entering a war they were almost certain to lose. Drawing on material little known to Western readers, and barely explored in depth in Japan itself, Hotta poses an essential question: Why did these men—military men, civilian politicians, diplomats, the emperor—put their country and its citizens so unnecessarily in harm’s way?

Book cover of Choices Under Fire: Moral Dimensions of World War II

M. Girard Dorsey Why did I love this book?

Bess is a tough taskmaster. He looks at twelve historical decisions and events in World War II and asks if the actors did the right thing. Did they behave morally, or could they have done better? He offers his own views, provides background, and raises questions to give readers a chance to develop theirs. 

Some events are well known—such as dropping the atomic bombs—but Bess asks the reader to look at kamikazes, war crimes trials, appeasement, and alliances with Stalin in novel ways. After reading Bess’s chapters, it can feel like you are learning about a new war. The answers to his queries are complex, but I feel like I have come to a thoughtful and informed conclusion at the end of each chapter.

2 authors picked Choices Under Fire as one of their favorite books, and they share why you should read it.

What is this book about?

World War II was the quintessential “good war.” It was not, however, a conflict free of moral ambiguity, painful dilemmas, and unavoidable compromises. Was the bombing of civilian populations in Germany and Japan justified? Were the Nuremberg and Tokyo war crimes trials legally scrupulous? What is the legacy bequeathed to the world by Hiroshima? With wisdom and clarity, Michael Bess brings a fresh eye to these difficult questions and others, arguing eloquently against the binaries of honor and dishonor, pride and shame, and points instead toward a nuanced reckoning with one of the most pivotal conflicts in human history.

Book cover of Leora's Letters: The Story of Love and Loss for an Iowa Family During World War II

Joy Neal Kidney Author Of What Leora Never Knew: A Granddaughter's Quest for Answers

New book alert!

Why am I passionate about this?

I'm the oldest granddaughter of Leora, who lost three sons during WWII. To learn what happened to them, I studied casualty and missing aircraft reports, missions reports, and read unit histories. I’ve corresponded with veterans who knew one of the brothers, who witnessed the bomber hit the water off New Guinea, and who accompanied one brother’s body home. I’m still in contact with the family members of two crew members on the bomber. The companion book, Leora’s Letters, is the family story of the five Wilson brothers who served, but only two came home.
