Allies at War: The Politics of Defeating Hitler

Rate this book
After the fall of France in June 1940, Britain was the only European country left to resist Hitler. Desperate for allies, Winston Churchill did everything he could to woo the United States to join the war on Britain’s side, to drive the Soviet Union and Germany apart, and to influence neutral countries to join the fight against Hitler or at least stay out of the conflict.

By the end of 1941, after the German invasion of Russia and the Japanese attack on Pearl Harbor, the Grand Alliance was in place. But the ‘Big Three’ – Churchill, Roosevelt and Stalin – were uneasy bedfellows and their partnership was soon plagued by mistrust, rivalry and deceit. Conflicts opened not just over strategy but over the post-war order – the extent of the United States’ global influence, the fate of Britain’s empire, and whether the Soviet Union would extend its territorial ambitions to eastern Europe. The seeds of the Cold War were sown while the bloody battles in Europe and the Pacific still raged.

Winning the War is a fast-paced landmark history that focuses less on military events than on the politics and diplomacy that made military victory possible. Drawing on many new sources, Tim Bouverie tells the dramatic story through the eyes and voices of the key players – politicians and diplomats, journalists and spies. And while the ‘Big Three’ naturally take centre stage, we also meet the Free French, Chinese nationalists and Yugoslav partisans. Ambitious, compelling and controversial, Winning the War offers a fresh perspective on the Second World War.

Pre-reviews for 'Allies at War':

‘Allies at War cements Tim Bouverie's reputation as one of the most talented young historians we have. Magisterial in scope, shrewd in its judgements, well-written and often amusing, Allies at War is the best book I have ever read about the politics of the Second World War. It is a book I wish I had written.’ – Tim Shipman

‘In Allies at War, Tim Bouverie fully lives up to the dazzling reputation he won with Appeasing Hitler. Again, he combines depth of research, shrewdness of judgment and lightness of touch. The result is an absorbing read as well as a major work of history, illuminating the drama and complexity of modern history's greatest and yet most troubled alliance.’ – Professor Robert Tombs

‘A sweeping, fast-paced narrative of one of the great turning points of the 20th century. Deeply researched yet highly readable.’ – Professor David Reynolds

‘A grand sweep of history - a brilliant narrative’ – Antony Beevor

Praise for 'Appeasing Hitler'

‘An astonishingly accomplished debut. - Antony Beevor

‘A brilliant and sparkling debut...that reads like a thriller. I couldn’t put it down.' - Peter Frankopan

‘An unusually talented writer, one of the most promising young historians to enter our field for years.' - Max Hastings

‘Every so often I've been escaping to the corner of my garden and losing myself in Tim
Bouverie's brilliant Appeasing Hitler. It's a compelling read that combines detailed research with a flair for narrative.’ - Nick Robinson, Radio Times

‘Drawing on an impressive and interesting range of sources and characters, Tim Bouverie has written a fascinating and scholarly portrait of a decade when credulity, self-interest and poor judgement prevailed tragically and inexorably over morality and good sense: this is the reporting of history at its best’ - Caroline Moorehead

‘Appeasing Hitler is the stunning debut of a major new narrative historian. A riveting and
depressing story which has resonance today as the democracies again face dictatorships.' - Professor Margaret Macmillan

‘In meticulous detail and with moments of novelty and insight… [Appeasing Hitler] should become a standard text on this inglorious episode… an exceptionally promising debut. He has great narrative abilities and his research has been extensive.’ - Simon Heffer, Daily Telegraph

‘Sparkling and witty... The best account of the subject that I have ever read. ' - Professor Sir Michael Howard

‘This gripping book is…valuable because it illuminates some eternal truths’ - Andrew Rawnsley, Observer

political decisions’ - Ian Kershaw

A brilliant book which compellingly narrates a complex and fascinating period in history. Amazingly for a book on WW2 there are new bits of archival evidence demonstrating the author’s scholarship and also providing funny anecdotes to counterbalance the darkest hours. Well written and well researched, I highly recommend this new book.

This is a diplomatic history of WW2 from the perspective of the victorious allies - told in terms of how different sets of allies had to work together well (or not) in the course of a particular event, campaign, wartime conference, or the like. It is a history of how thee victors had to fight among each other as they were fighting the axis enemies in order to win. The norm was one of conflict and disorder - and that is when everything worked out. This is an inventive take on the idea that “war is hell” and that fighting alongside allies is a terrible approach to war, but still better than not having allies in fighting a world war.

I am very familiar with the history but this is a very inventive way to structure a new WW2 history.

A must read!

Beautifully written, fascinating and often funny book on the diplomatic history during WW2. It could hardly be a more relevant time to revisit Allied relations (including China) but also, to discover more about relations between the Allies and neutral states- particularly in such a compellingly told narrative. I devoured it in a week and could not recommend it more.

As this book started out I thought it was going to be a rehash of the allied leaders’ relationships but it is much more. Very in-depth analysis and I really enjoyed the maneuver for a post world war world. Good stuff here.

While not quite the masterpiece that Appeasement was, Bouverie has nonetheless produced another fascinating, well-researched, and well-written history about three of the most important men in 20th century history. The chapters delve into certain lesser-known areas of WWII history, including British involvement in Iraq and the (less than admirable) decision of the Irish government to remain neutral, to the point their PM personally offered condolences to the Germans after Hitler's suicide (while only sending a telegram to his U.S. counterparts after FDR's passing).

The minor faults I would find in his work are that he sometimes mischaracterizes certain aspects of U.S. history, and that he glosses over or overlooks some important events during the timeline he's writing about (i.e., Churchill's loss of the premiership to Clement Atlee in 1945 and Atlee's presence at Potsdam that year). Overall, however, still a solid work that is very much worth reading.

At some level, we all know something about the WWII “alliance” of US, UK, and Russia. This book takes you into the “engine room” of the alliance, showing its complicated, shape shifting, nature at all levels of the countries involved as the unexpected events of war and international/national politics occurred. The author believes that all members of the alliance (including Russia) wanted it to continue cooperatively after the war (and apparently FDR so believed). Stalin’s conduct within days of the end of the European war entirely disproved that idea.

An interesting “supplement” to the book is The Economist’s Archive 1945 which, with commentary and explanation and video/photos, traces its coverage of the war in 1945.

This is a dry and solid but not spectacular book — and that is almost entirely about the three allies’ work in the ETO. There’s nothing about actions in the Pacific and almost nothing about actions in South Asia or China.

Because of that, and once again, the “dry,” and also because of one issue noted below, I’m going 3.5 stars rounded downward.

Very good on the British dealings with de Gaulle, and with the Free French beyond him as well. The “French vs French” in Syria pretty good.

Good, though possibly overstated on its value, on British diplomacy with Franco’s Spain.

Did not know that Guy Burgess in August 1939 may have sabotaged Franco/British-USSR negotiations by saying in August 1939 it was British preference to work with Germany and against Russia.

Claims FDR knew about Soviet atomic spying. Weirdly, Duck Duck Go’s version of AI search says FDR knew nothing about spying at Los Alamos, but when I change search terms, that he DID know about spying in the Manhattan Project. That said, Duck Duck’s AI is in general no better than Google’s. Given that this semi-throwaway comment isn’t further developed, and that the bits I could find supporting it online were from various “Churchill project” websites, I think something has been at least overread if not misread.

Good thumbnail on Greece late 1944.

Beyond the special pullout notes above, this is a decent to solid, but again not special or spectacular, all-around read of World War II and the three western leaders.

For a very good "small slice" book, see "The Stalin Affair."

*I received a free ARC from the publisher through NetGalley in exchange for my honest review*

This is not a book for the casual history reader or designed to be read through quickly. This a very dry read packed with a lot of information which the author does his best to liven up. My personal difficulty with the book was not being as well-versed in all of the events unfolding in Europe in the lead-up to WWII. My high school history courses tended to focus solely on the American experience during the 1930s with a sprinkling of what was happening elsewhere. I often felt like I was trying not only to piece together events but also keep straight all of the players on the Allied side. This is also why I found the book so interesting, it was taking me through these historical events of which I had very little awareness and giving me a more thorough understanding of what had happened during these years. I would recommend this book to any readers who want to know more about this time in history, especially high school students with an interest in WWII history who want to do more of a deep dive into history than they will get in any of their Social Studies classes.

A sweeping history of the diplomatic relationship between the Allied Powers of WWII. In its main thread, where this book discusses the evolving relationship between the USA, UK and USSR, it does not break much new ground, but strikes a good balance between detail and conciseness.

The rewarding pieces are the side stories that, by their nature, have not previously been described as much, or at least not in one place: The tangled relationships with Vichy France and the Free French; the complex negotiations with neutral countries such Spain, Ireland and Turkey; the difficult position of China as a great power; the tragic histories of Greece and Poland. There is a lot more that could be elaborated on in a complex, global conflict: Indeed entire continents worth of foreign relations and complex alliances remain to be discussed.

Whether you will find this book rewarding, disappointing, informative or boring depends a lot on your background. If you want a solid introduction to the topic, which covers all the main stories and offers a handful of fresh angles, this will do very well.

What you think you know about the relationship between the Allied leadership in WWII is only partial until you have read this book. Churchill's strengths and foibles are concisely but clearly described as are Roosevelt's charm and utter disingenuousness. De Gaulle comes across as abrasive and obnoxious as he could be, but also what was admirable in him becomes evident as well. The perfidy of the Vichy French is elucidated. Stalin and the Soviets remain a cypher.

Superb addition to our understanding of the negotiations and background to key policies that set WW2 in motion and the world to come after.

The sheer volume of research behind this is nothing but impressive. The quotations appositely illustrates personalities and views at critical junctures; some are truly humorous. To have selected these from the mountain of sources the author used is an admirable effort in itself.

The role of communist espionage is several times alluded to, but not explored. That would have been beyond the ambit of this narrative, but a reading of Herbert Romerstein afterwards would fill in some of the blanks.

This book was a bit like a Netflix movie, it jumped backwards and forwards in time making it a very disjointed read. I get what the reason is, grouping things together that are related, however from a reader point of view it was very difficult to get into. I found the writing style a bit odd and not really for me, made it to 20% and had to give up.

Although I must admit from the bit I did read I discovered things about WWII that I never knew. I guess watching too many movies you sometimes think everyone "played nicely" with each other. Though I would never be that naive, I never knew about Force H in Oran. All things Governments would likely rather forget I expect!

Good book but too tough a read for me.

Well 697 not 1006 pages of a re-evaluation of the various allies and alliances in WW2 (including footnotes, maybe 1-2 pages per chapter, but photos are not counted.)
As expected this book provides details and insights. Perhaps the most important is a re-evaluation of Yalta as far less of an allied failure to contain Stalin. Plenty of criticism for the relationship between Roosevelt and Churchill. Details I haven't seen for the prickly relationship between Churchill Roosevelt and their French allies especially their bête noire, Charles de Gaulle.
A long read that doesn't cover battles except briefly mentioning turning points- Stalingrad, invasion of Sicily, failure to support Warsaw uprising. Discussions of the division of Germany.
Highly recommended for someone who has the patience to finish it.

Very enjoyable, with some amusing anecdotes thrown in to boot, this narrative of the politics between the Great Men of the war is certainly interesting, but doesn't cover any new ground that a World War II aficionado wouldn't already have a firm understanding of - unlike, for instance, Stalin's War by Sean McMeekin.

This is puzzling as the topic, structure and size of the book wouldn't automatically lend itself to anyone who doesn't have such a precise interest and knowledge. This isn't to detract from the book, which is well-written, or the author, who is clearly knowledgeable on the subject, and certainly I wouldn't deter anyone from giving it a read.

A fantastic work of scholarship, insight and readability.

I have read widely on the subject over the years but there was so much there that was new to me. The diplomacy in Spain and the machinations of Vichy in Syria and Tunisia were two standouts. What a scummy lot Vichy were!

The depth of the research was very evident but Bouverie shows great skill in wearing that lightly in the interests of the narrative. I really liked the irony and pen portraits.

He is now now right up there with the best of today’s historians.

A truly gripping amalgam of history with literature in a rare combination of the gripping with the erudite, Bouverie’s painstaking delve into original sources is illumined by shafts of clear common sense in which the internecine rivalries, the ideas - private and for public consumption – and often the all-too-human feet of clay of the titans of WW2’s almighty conflict are exposed for dissection.

In Allies at War, the author has found a new way to view the Second World War, viewing it through the lens of Allied states and the alliances that helped win the war, sometimes in spite of the struggles of competing agendas. Excellent research combined with an elegant writing style make this an enjoyable read on many levels. Highly recommended; thanks to the publisher for a chance to read an advance copy.

This is a superbly written book, well-structured and approachable despite the complexity of the subject.

For me, it was particularly instructive to learn how early in the war the powers were doing detailed planning for the post-war settlement.

The Epilogue is a brilliant essay summarising the challenges, constraints, and finely balanced decisions that the Allies were continually having to make.

Very highly recommended.

A bit dry, with entertaining passages only periodically sprinkled in, by apparent accident. However, despite the density of the materal and dry manner of the author, this book undoubtedly gives a new perspective on the activities of WWII through its unique lens of examining events through diplomatic channels and maneuvers.

Wears its considerable learning lightly while painting a vivid picture of the dysfunctional yet supremely functional relationship between the allied powers during the Second World War. The focus on diplomacy casts a new light on what is usually a primarily military topic with a tone that verges on the jaunty at times, which prevents the narrative becoming dry and dusty.

So much information, so many facts , so many events and so many characters. This book goes some way to explaining the relationships between politicians , soldiers and events in an understandable manner.
A good read.

This book is brilliant! It’s so enjoyable to read yet extremely well-researched and scholarly.
I thought the reviews giving 5 stars and saying it was ‘a masterpiece’ might be a bit over the top but they are right!

I would thoroughly recommend this book - not only was it filled with lots of new information about the Allies (not just the Big 3), it was also surprisingly amusing; a real page turner. Tim is a brilliant writer, and I am already looking forward to his next book.

An absolutely epic read. Incredibly fair and detailed examination of Roosevelt, Churchill and Stalin, their characters and relationships which held the odd triumvirate of Allies together until victory in Europe was achieved.

Probably slightly strange take but I honestly found this very funny. Lots of very funny anecdotes about Churchill not wanting to watch Stalin's after dinner films etc.

Also very serious and interesting perspective on diplomacy and the power struggles behind the scenes.

I really enjoyed Allies at War. Bouverie tells the story of Churchill, Roosevelt, and Stalin in a way that feels both exciting and easy to follow. It shows how messy their partnership was, but also how it managed to hold together long enough to win the war. A fascinating and very readable history.

This is not a bad book. It is a lot of information and content. I did learn a lot while reading it. It was interesting just not my normal reading. I'm glad I took the time to read it though. Thanks Penguin Rabdom House for the copy.
