Wolfpack: Inside Hitler's U-Boat War
From a top scholar of World War II, the definitive history of Germany’s U-boat campaign that challenged British naval supremacy and brought international trade to its knees
Winston Churchill once remarked that the only threat to truly frighten him was the peril of Nazi U-boats. Over the course of World War II, Germany’s submariners sank over three thousand Allied ships, nearly three-quarters of Allied shipping losses in all theaters of the war. In the process the submariners endured horrific conditions and suffered a 75 percent death rate, the highest of any arm of service in the conflict. Yet their story has never been told in full.
In Wolfpack, historian Roger Moorhouse tells the story of the Battle of the Atlantic from the point of view of the German submariners. He tracks these men from the enthusiasm of the war’s early days, buoyed with optimism about their cause, through the challenges of the Allied counterthreat, to the final horrors of enemy capture and death in the depths. It is a story of courage, certainly, but also of fear, privation, and—ultimately—failure.
Drawing extensively on war diaries, archival records, and the voices of the German submariners themselves, Wolfpack is a story of technological brilliance, dramatic naval engagements, and extraordinary human endurance.

About the author
Roger Moorhouse
38 books194 followersLiving the Dream. Historian and author of an international bestseller - "Berlin at War" was #1 in Lithuania :-) - as well as a few other books, such as "Killing Hitler", "The Devils' Alliance" and "First to Fight" - the last of which won the Polish Foreign Ministry History Prize in 2020.
I write mainly about Nazi Germany and wartime Poland, but I fear that might scare some people off, so I'll just call myself a writer of history books.
My current book (published in the UK in August 2023) is "The Forgers", which is the fascinating story of the Ładoś Group - a ring of Polish diplomats and Jewish activists operating out of wartime Switzerland - who were forging Latin American passports to help Jews escape the Holocaust. It is a VERY interesting subject - so I would urge you to get a copy!
I hope you enjoy my books. Any questions or queries or just wholesome praise, do let me know...

“At 1:13 a.m., [Gunther] Prien gave the order to fire again. Stopwatches were set, and three torpedoes sped away, one after the other, into the darkness of Scapa Flow…Two of the three torpedoes slammed into the starboard flank of the battleship, below the waterline, sending a plume of spray as high as the bridge and an explosion that illuminated the night. In Prien’s words, it was a scene that none of them would ever forget: ‘A wall of water shot toward the sky. It was as if the sea suddenly stood up on end. Loud explosions came one after the other like drumfire in a battle and coalesced into one mighty ear-splitting crash.’ He watched as the stricken battleship listed to starboard, her bulkheads ruptured. Then the magazine exploded, sending a fireball through the heart of the ship…With that Prien turned U-47 for home and made good his escape. Meanwhile, his target capsized in a little over thirteen minutes, taking more than 800 of the 1,200-strong crew to their deaths. The following day, as the bodies of the dead started to wash up on the shores of Scapa Flow, Prien and U-47 began their journey southward across the North Sea…
- Roger Moorhouse, Wolfpack: Inside Hitler’s U-Boat War
There are times in your life when you just want to read about submarines. This is perfectly understandable. There are few things as dramatically satisfying as the story of a submarine at war.
When the submarine is an antagonist, it stalks the tale like a shark, a terrifying menace arising from the cold depths of the sea. When the submarine is a protagonist, it manages to encapsulate most of humanity’s greatest fears into a small steel cylinder: darkness, confined spaces, the threat of fire, the possibility of drowning, the existential dread of disappearing without a trace. There is a reason why there are so many movies and novels about submarines. Even when they are bad, they are generally pretty good.
Roger Moorhouse’s Wolfpack is a nonfiction work, yet it succeeds so well because of Moorhouse’s keen eye for novelistic detail. Though carefully researched and full of strategic observations, it is at its best when describing the lives lived at the extreme edge of survival.
***
Wolfpack is a well-mixed blend of chronology, theme, and pure storytelling. It is never easy to juggle these different imperatives, but Moorhouse does it with the practiced ease of a successful popular historian. While he covers a lot of ground – starting with the prewar years and going all the way through the end of the war, with the last undersea boat fleeing to Argentina – this is eminently accessible, with the material broken down into sixty-one short chapters.
At the macrolevel, Moorhouse traces the ebb and flow of the U-boat war in the North Atlantic, the Mediterranean, the Indian Ocean, and America’s eastern seaboard. These portions of the book are designed for those with quantitative minds, as Moorhouse provides a lot of figures showing gross tonnage available versus tonnage lost. His conclusion is that the impact of the U-boat war is somewhat overstated.
Winston Churchill – in one of his many gaseous oversimplifications – once stated that Germany’s U-boat blockade was the only thing that ever scared him. However, Germany only ever had a narrow window of opportunity early in the war, before American industrial might could easily make good any losses. At that point, though, Admiral Karl Doenitz lacked the necessary resources, as his Leader went to war without being ready. By the time Doenitz had the hundreds of submarines he initially desired, it was far too late.
***
Statistics have their place, but numbers are an impersonal thing. Moorhouse gives the numbers meaning by weaving intimate set pieces into the narrative. These follow various submarine crews as they stalk convoys, survive depth charges, try to avoid Allied air patrols, and generally attempt to survive an environment designed to kill them in unpleasant ways.
In order to craft these scenes, Moorhouse uses a variety of sources, including memoirs from survivors, extant letters, logbooks, Enigma decrypts, and occasionally evidence gleaned from the wrecks that have been discovered on the ocean floor. Utilizing all these parts of the puzzle, Moorhouse delivers moments of tension and danger. There is also room for the absurd, as in the case of U-1206, which sank due to a malfunctioning high-pressure toilet.
***
Interspersed throughout Wolfpack are thematic chapters that explore different realities of submarine life such as food, hygiene, shore leave, training, shipboard rituals, communications, and political indoctrination.
Perhaps the most interesting of these themes is the evolution of submarine technology. For instance, early in the war, the Germans – like the Americans against Japan – could not get their torpedoes to work.
Throughout Wolfpack, Moorhouse profiles different sub types, including the Type VII, the most widely-built German sub of the war; the Type XIV supply sub, known as the milk cow; and the more-advanced Type XXI and Type XXIII electric boats. He also discusses incremental advances such as the “snorkel,” which allowed diesel craft to charge their batteries while underwater.
The important thing to keep in mind is that the U-boats of the Second World War were submersibles, but not true submarines. Much of a U-boat’s time had to be spent on the surface. Only a limited interval could be maintained below the waves before battery power went out forever. This was a challenge the Germans tried to overcome. To an extent they did, but far too late to make a difference. Moreover, these breakthroughs came with consequences. Hitler staked a lot on wonder weapons, spending enormous sums on quality that might better have been spent on quantity.
***
Wolfpack arrives at an interesting cultural moment. Despite the irreparable harm they caused – such as the cowardly murder of millions of Jewish men, women, and children – Nazis have somehow returned to the mainstream. Amplified by social media, Nazism and its white supremacist dogma has once again found a foothold among those both disillusioned and entitled.
This is worth mentioning because Moorhouse writes from the perspectives of German sailors. Obviously, not all of them belonged to the Nazi Party. Nevertheless – as Moorhouse rightly notes – they were all engaged in supporting the worst cause for which mankind has ever gone to war (which is saying something, as there have been few worthwhile causes for war). It can make one a tad bit uncomfortable being put in the position of empathizing with Hitler’s minions.
Suffice to say, Moorhouse ably deals with this tension, separating the ordinary sailor from the cause when justified, but also noting the impact of Nazi ideology on the Kriegsmarine.
***
One of the arguments Moorhouse makes in Wolfpack is that the U-boat campaign was the “cleanest” aspect of Germany’s involvement in World War II. He observes that early in the war, sub crews attempted to adhere to the “Prize Rules,” in which merchant ships were stopped, boarded, and their crews allowed to abandon ship. There were also instances in which German subs brought aboard survivors, or provided provisions to men in their lifeboats.
There is some truth in Moorhouse’s assertion, even if it is only relative. At the very least, the U-boats were not directly involved in the Nazi’s annihilationist projects. Yet Moorhouse is careful not to stretch the proposition too far, for the U-boats were quite clearly an important factor in achieving Nazi war aims, including the mass slaughter of noncombatant populations on racial-religious grounds.
In the end, any sins of the U-boatmen were mostly paid in blood. Around 75% of German submariners were killed in action. Roughly half of the submarines lost simply disappeared with all hands. Unlike the concentration camp guard who quietly slipped back into his middle-class life, most of the young crewmen who sailed for Hitler did not survive to rationalize their actions.

Naval warfare is often told in terms of tonnages and strategy, but in this book author Roger Moorhouse focusses on the experiences of the people that actually waged this war. He shows that the U-Boat war was mainly an existential battle where survival was often more the rule than the exception.
I really liked the balanced approach that Moorhouse offered: it succeeds in explaining the complex military developments without losing the story. At the same time, the story feels almost claustrophobic. Men operating under intense pressure where very mission could be their last.
I read this book after finishing Battle of the Arctic: The Epic Story of World War Two Amongst the Ice and I must admit that this book was a worthy companion (or follow-up). Where Sebag-Montefiore’s book focussed on the Allies, this book shows how life was for the Germans under the sea.
Just as in The Battle for the Arctic, the combination between analysis and human experience is what gives this book its strength. It is no heroic story, but rather a book about endurance, risk and the limits of control during wartime.

Unique writing format for a history book that I greatly enjoyed. Content was quite engaging!

It is a trope, immediately recognisable. A U-boat emerging from the depths, menacing; a brutal hunter, devoid of all humanity. Torpedoes launch, mercilessly locking onto their prey, engulfing the unwitting quarry in flame and death. On the surface, panic erupts as men burn and drown, or scramble for any temporary safety in the featureless expanse of the Atlantic. The deed done, the mechanical beast once again submerges, leaving its victims to die – slowly or quickly – in the unforgiving water above.
For over eighty years, this has been the image of the German submarine during the Second World War. It is a looming spectre, a menace that would appear from nowhere, wreak havoc and destruction, and then disappear just as quickly. It is terrifying and debilitating: even the ‘great man’, Winston Churchill himself, admitted that ‘The only thing that ever really frightened me during the war was the U-boat peril’. But it is not just the Predator-like ability to come and go at will, nor the strategic danger presented by the Battle of the Atlantic, that makes the U-boat war so enduringly disturbing. Instead, it is the fate of the survivors: stranded, exposed to the elements, slowly baking or freezing, starving, and dying of thirst while surrounded by water.
Yet, this is an emotional response, which barely leaves space for the facts – or, indeed, for the other side. At last, however, there is a historian who has challenged it and, in Wolfpack: Inside Hitler’s U-Boat War, Roger Moorhouse excels in presenting an entirely new perspective. Surely, Moorhouse asks, as we approach the centenary of the start of the Second World War there is now room to consider the other aspects of the U-boat war; to leave aside those immediate gut reactions – reactions that still fuel the various media industries – to approach the subject with objectivity?
This, of course, is a rhetorical question, because Moorhouse goes on to write a thrilling, compelling and enlightening history of the U-boat war told from the German point of view. Through detailed research, using archives and resources rarely touched by anglophone historians, and astonishing statistics whose presentation belies the amount of work that has been done behind the scenes, we are left in no doubt about the potential – and ultimate fruitlessness – of the U-boat arm. With more than half of all combat U-boats failing to sink anything, ever, there can be no argument other than that the idea was worse than the reality. This, of course, is not to imply there was no inherent danger, just that – as with so much about the Nazi regime – treasure and energy were misspent and mistimed.
But well-honed arguments, backed up by irrefutable evidence, about the true extent of the threat of the U-boat is only half the story. Instead, what really confounds in Wolfpack is the human angle. No longer are we allowed to think of the men inside the machines as nameless, faceless automatons, or devils hell-bent on causing as much damage and suffering as possible. For Wolfpack is a deeply personal story: of fear, of suffering, of a death rate ‘unmatched in any other branch of service, in any army, in any theatre of the Second World War’, and of the all-pervading stench of weeks spent in tightly packed, increasingly airless tube surrounded by all manner of filth and detritus. But also of camaraderie, of optimism, of bravery and, indeed, of chivalry – of the times where the ‘solidarity of the sea’ overrode more immediate, political concerns and compelled these alleged ‘demons’ to provide the enemy with sustenance, with medicine and, occasionally, with a lift into port.
To many readers, immersed for decades in the media stories of the U-boat war, this last might be hard to credit. And anyway, as Moorhouse says, ‘It matters little if a single theatre of a war was fought with a modicum of honour when the cause as a whole was so morally sullied as to be synonymous with evil itself.’ But, if anyone can make us reassess our treasured opinions and to consider another perspective, then it’s Roger Moorhouse.

Splendid. A thoughtful, in depth examination of both the course of the U-Boat war and the experiences of those waging it. A lot more nuanced than some earlier titles, and focusing both on the important morale aspect as well as the considerable hardships faced by the men involved.
Very much recommended, especially as an entry to the subject.

Superb overview of the trials and tribulations of the U-boat arm of the German Navy in the Second World War. I was lucky enough to pick up a copy at a festival pre the official publication and finished it quickly as the author has a very effective narrative pace and the story is fascinating. You get a very good sense of what life was like on board a u-boat, and how the technology and tactics evolved during the war. Highly recommended.

No spoilers,
I must admit there are plenty of material on the Battle of the Atlantic, but those are mainly from the allied side. That is to expected since history is always written in glorious light of the victors. However, I was surprised to learn so much about what the uboat fleet and their crews went through during the war. For anyone who is truly interested in this subject. I would recommend giving this title a read.

Excellent historic account of the U-Boat war. This is admittedly the fonly work of non-fiction on the submarine war I’ve read so I don’t have any other writings to compare it to, but it came across as well researched and paced. Prior knowledge has come from various documentaries and portrays in film and TV.
The writing style leant more towards the human story rather than dry facts, which is the way around I prefer. Yes, there were clear chronological details about the development and building of the various submarines models, individual submarines, dates of patrols and statistics around sinking but the text would try to go back to first hand accounts, diaries and even when describing facts, Moorhouse would always try to humanise the experience.
Ultimately, the experience for the submariners was a uniquely challenging one and I would say the most psychologically challenging of any sector of the war. Months at sea, may of the crew rarely seeing daylight, an impossibly cramped existence full of unimaginable levels of stench with combinations of oil, recirculated air, body odour, rancid food and of course the smell of the toilets - all tinged with the smell of fear. The combined stress in that confined coffin resulted in the highest percentage of losses of any armed force in the entire war… 75% of the German submariners failed to return. Their remains never recovered or family even knowing where or why they’d died.
The book delved into the bizarre laws of the sea, chivalry and the darker moments in their campaign. Rules that were sometimes and often (by both sides) broken especially when it comes to sinking freight and non-military ship along with the logistics of picking up survivors/radioing details that a ship has been sunk to the allies. The press coverage, propaganda and media-spin was excellent covered with some key events.
Similar to the British bomber pilots, the U-Boat veterans received a less-welcome response from the public. Perhaps too eager to forget about some of the more controversial and underhand nature of the way they delivered death as the unseen enemy, made more complicated as the defeated. At the beginning of the war, the U-Boat captains and crew were heralded as the Heroes of the Third Reich. Idolised during the so-called ‘Happy Times’ as they tightened the noose around Great Britain as she struggled alone before the Royal Navy, Coastal Command and RAF started to adapt tactics and find ways to beat them.
An aspect I had never considered was what happened the U-Boat crews that were on patrol when Germany surrendered. This final chapter was one of the most interesting of all as it dealt with the psychology of the crew, their fears of surrendering to the Soviets, the use of Black Flags for surrendering, Captains scuttling their U-Boats and some of the decisions made on if they could make it to either surrender to the British/American forces or find a way to escape to South America and reinvent themselves. One particularly unique account told of a couple of Japanese soldiers who happened to have been picked up choosing to end their own lives rather than face the shame of surrendering.
One of the highest praises for this book is how it kept its focus. By not focusing much on the allied experience, they felt like a mysterious ‘enemy’ and threat to the U-Boats throughout. Initially easy prey then a formidable opponent. Too many documentaries that are meant to be on the Wolfpacks get completely sidetracked on the allied side, going into great details on the development of tactics and countermeasures utilised by the RN leaving you feeling like you haven’t got into the experience of day-to-day life of the submariner.

One particularly unique account told of a couple of Japanese soldiers who happened to have been picked up choosing to end their own lives rather than face the shame of surrendering.
One of the highest praises for this book is how it kept its focus. By not focusing much on the allied experience, they felt like a mysterious ‘enemy’ and threat to the U-Boats throughout. Initially easy prey then a formidable opponent. Too many documentaries that are meant to be on the Wolfpacks get completely sidetracked on the allied side, going into great details on the development of tactics and countermeasures utilised by the RN leaving you feeling like you haven’t got into the experience of day-to-day life of the submariner.

Wolfpack: Inside Hitler’s U,Boat War by Roger Moorhouse is a riveting, authoritative, and deeply human account of one of World War II’s most harrowing campaigns. Told through the eyes of Germany’s submariners, Moorhouse delivers the definitive chronicle of the U-boat offensive that nearly severed Britain’s lifeline and reshaped the global struggle for control of the seas.
Combining meticulous research with cinematic storytelling, Moorhouse immerses readers in the claustrophobic reality of submarine warfare the silence before attack, the thunder of depth charges, the unrelenting cold and fear that haunted every dive. Drawing from diaries, mission logs, and survivor testimonies, he reconstructs the evolution of the “wolfpack” strategy and its ultimate unraveling as Allied innovation and endurance prevailed.
More than a chronicle of naval tactics, Wolfpack is a study in courage, delusion, and mortality a reminder that technological brilliance and human valor often collide with the moral abyss of war. Readers of Antony Beevor, Max Hastings, or James Holland will recognize Moorhouse’s masterful blend of scholarship and narrative drive. In Wolfpack, history surfaces not as distant record but as a living, breathing struggle one that still echoes beneath the waves.

To paraphrase Antony Swofford, all war movies celebrate war. Do all books with Hitler in the title celebrate him? To his credit, the author works to add complexity and nuance to the story of U-Boat sailors, working both to dispel the myths of the ruthless Nazi (the navy in general and U-Boat service in particular were comparatively less Nazi-fied than other parts of German society) and the myth of the U-boat crews as hapless victim, as well. It was an ugly and, quite literally, stinky war. It did little to affect the war's ultimate outcome. And it is an interesting mirror-image to the American undersea war in the Pacific-- just as brutal to merchant mariners and deadly dangerous to submariners, but with a far lower casualty rate for the later and much more war-winning effect.

This is Second World War history at its best, on par with James Holland and Robin Neillands, meaning that Moorhouse is not only a skilled historian but a talented writer as well, not always an easy combination to find.
There is not a paragraph in this book that does not educate and engage: the narrative did not flag for a minute. The story of the U boat war is told from all sides, but with the emphasis on the submariners themselves. Their war was unique and horrific, for both they and their victims.
Everything from day to day life on board the U boats to the weapons they used, to the strategies that both sides used to prosecute the war are covered, from big picture to details - this book is an absolute gem.

I have read many WWII submarine warfare histories. I believe this is the first one to concentrate on the German experience and it is valuable for that reason. As in the Pacific theater, the killing went on long after the ability to replace resources was so much greater for the Allies than for Japan or Germany made the outcome inevitable. The conditions inside the U-boats were awful; this topic was not covered to any extent in my previous reading. In addition, the statistics presented here are devastating for the crews including the high rate of U-boats being lost on the very first combat patrol.

Picked up a hard copy and was instantly gripped (so much so that I finished the last part as an audio book having had to leave the print version with its owner).
Vividly creating the camaraderie, integrity and innovation of this corps of incredibly young men, it was a revelation that dispelled many U-boat stereotypes and myths.
Excellently researched and written, this eye opening history of the war beneath the waves (and obsessive power driving it from above) is a gem of a book.
A superb, enjoyable and emotional read.

An excellent history of Hitler's U-Boat War written from a German (Kriegsmarine) perspective. Provides bags of insight into what it was like to serve aboard Donitz's submarines and explains how the fortunes of the U-Boat waxed and waned over the course of the Second World War. An easy and well-paced read which I would have no hesitation in recommending to anyone interested in the Atlantic War.

Thorough and informative story regarding the U-boat experience in WW2. Neither glorifies or demonizes the U-boat crews, but paints them with the requisite complexity and paradoxes of war. Provides readers with a strong understanding of the U-boat experience and the dreadful survival odds for crews later in the war.

A brilliant book and essential reading for anyone who wants to understand the Battle of the North Atlantic from under the waves. Roger Moorhouse is a terrific writer and a first rate historian and this book is as good as anything else he has written.

Brilliant book written from the German perspective. The conditions experienced by the uboatmen were horrific and the chances of survival the least of any service in army in ww2.

A brilliantly written account of the German U-Boat war in WWII.

Highly researched. Explicitly explains most everything I have read or heard about the Uboat war.

I've never read a history of the Battle of the Atlantic from the German perspective. Deeply intriguing and also find the plight of the third generation of commanders very harrowing.

Quite brilliant and a very easy read for this type of material. Gripping for a non-fiction book.

Even though they were our enemies, it is amazing what these teenagers accomplished. It is frightening that most of these kids never came back.

This a great overall book of the U-Boats. It gives a glimpse into the life on board, new inventions for the war and how the fleet slowly fell apart the longer the war went on.

Great history and an entertaining read.

Captivating, and detailed. Roger has managed to give us a deeper understanding of what the u-boat arm went through in the war, and it is fascinating. Enjoyable from start to end.

Brilliantly paced. Equal parts detailed and emotional stories. No cahpter outstayed its welcome. I will be seeking more titles from Moorehouse. These sorts of books fantastic.
