The Polish Soviet War is one of those conflicts whose importance seems considerably greater than the attention it receives in most general histories of the twentieth century. Adam Zamoyski sets out to correct some of that neglect in Warsaw 1920: Lenin’s Failed Conquest of Europe, first published in English by HarperPress in 2008. It is a relatively short book, especially considering the complexity of the campaign it describes, and that brevity is simultaneously one of its greatest strengths and its most obvious weaknesses.

Zamoyski begins with the extraordinary political circumstances surrounding the rebirth of Poland following the First World War. Poland had returned to the map of Europe after more than a century of partition, but neither its borders nor its relationship with its neighbours had been satisfactorily resolved. To the east, the Bolsheviks had survived the worst of the Russian Civil War and increasingly regarded revolution as something that should not remain confined within Russia. Poland therefore became much more than disputed territory between two emerging states. It stood between Bolshevik Russia and a Germany suffering political and economic turmoil in the aftermath of defeat.

One of Zamoyski’s strengths is that he does not reduce the conflict to a simple story of Polish resistance to Soviet aggression. Józef Piłsudski had his own ambitious objectives, particularly his attempt to establish a wider political arrangement in eastern Europe and his offensive into Ukraine. The Polish advance on Kiev consequently occupies an important place in the story. It initially appeared successful but ultimately left Polish forces dangerously extended and helped create the circumstances for the enormous Soviet counteroffensive that followed.

This is where the book becomes particularly effective as military history. Zamoyski is very good at describing a campaign characterised by enormous distances, uncertain intelligence, exhausted troops, improvised formations and rapidly changing fortunes. Armies advance spectacularly and then appear almost to dissolve when supply, morale and command arrangements fail to keep pace. Cavalry remains operationally important, while railways, horses and marching infantry coexist with aircraft, armoured cars and other products of modern warfare. The result is a battlefield that feels transitional, somewhere between the nineteenth century and the increasingly mechanised warfare that would dominate Europe twenty years later.

The personalities are equally important. Piłsudski, Mikhail Tukhachevsky, Semyon Budyonny, Lenin, Trotsky and Stalin emerge not merely as names attached to armies or political movements but as individuals whose ambitions, assumptions and personal relationships affected events. Zamoyski is especially effective when showing how both Polish and Soviet commanders operated with incomplete information and frequently misunderstood what their opponents were doing. Contemporary reviewers have similarly noted his ability to combine battlefield movements with portraits of the principal commanders and the wider political setting.

The centrepiece is inevitably the Battle of Warsaw in August 1920. Zamoyski explains how apparently victorious Soviet armies reached the approaches to the Polish capital only to find themselves increasingly vulnerable. Polish resistance stiffened while the Soviet advance became dangerously extended. Piłsudski’s counterstroke against the exposed Soviet position transformed what had appeared likely to become a Polish catastrophe into a remarkable military victory.

Importantly, Zamoyski avoids presenting the result simply as the product of miraculous Polish heroism. The so called Miracle on the Vistula was produced by command decisions, operational opportunities, Soviet mistakes, intelligence, morale and the ability of Polish forces to recover sufficiently to exploit the weaknesses of their opponent. The Soviet command structure was far from harmonious, and the behaviour of the Southwestern Front, with Stalin among its political leadership, contributed to the failure to concentrate Soviet power effectively against Warsaw.

There is much to admire here. The narrative moves extremely well and complicated operations are generally explained without burying the reader beneath orders of battle and minor tactical detail. The maps are particularly important because this is a campaign in which geography and movement are fundamental to understanding what happened. Zamoyski also succeeds in conveying the confusion of operations rather than presenting the campaign retrospectively as a neat sequence of predetermined manoeuvres. Contemporary commentary has rightly praised this ability to make complicated battlefield movements understandable.

There is, however, a price for this readability. At around 160 pages in the original illustrated HarperPress edition, although other editions run longer because of format and illustrative material, this is not a comprehensive study of the Polish Soviet War. The political and diplomatic background is necessarily compressed, while the social history of the conflict receives relatively limited attention. The experiences of civilians, competing national movements in the borderlands, Ukrainian aspirations and the complicated ethnic politics of the region deserve considerably more examination than the book has room to provide.

The treatment of the aftermath is also somewhat too brief. This matters because Zamoyski places considerable emphasis on the proposition that Warsaw was a decisive moment for Europe. If that claim is accepted, then the longer term consequences deserve more sustained analysis. The Treaty of Riga, the failure of Piłsudski’s broader eastern ambitions, Polish Soviet relations during the interwar period and the consequences for Ukrainians and Belarusians could all have been developed further. This criticism has also been made elsewhere, with reviewers noting that the political consequences and non military dimensions of the war are considerably less developed than the campaign narrative itself.

I am also slightly cautious about the subtitle, Lenin’s Failed Conquest of Europe. It is certainly effective and captures the international ambitions surrounding the Soviet advance, but it risks making the outcome appear more straightforward than it actually was. Bolshevik leaders hoped that revolution might spread westwards, particularly into Germany, but the suggestion that the Red Army was on the verge of simply marching across Europe can push a complicated political and military situation rather too close to counterfactual certainty. The significance of Warsaw does not need to be exaggerated for the battle to remain extremely important.

There is another difficulty created by the book’s concision. Zamoyski moves between armies, formations and commanders quickly. Readers already familiar with the campaign will probably have little trouble following these changes, but newcomers may occasionally find themselves trying to remember exactly which army is advancing towards which river and under whose command. Other readers have identified the same problem, particularly the rapid switching between Polish and Soviet commanders and formations. More detailed operational maps would alleviate some of this problem.

None of these criticisms seriously undermine the book because Zamoyski was clearly not attempting to produce the definitive academic history of the war. What he has produced is something arguably more useful for the general reader: an accessible introduction that demonstrates why the campaign deserves further study. The underlying scholarship is considerably stronger than the pace and accessibility of the narrative might initially suggest, and assessments of the book have noted both the breadth of Zamoyski’s knowledge and his deliberate decision to write a synthetic account rather than an exhaustive specialist study.

For the military historian and particularly the wargamer, there is also a great deal here to think about. The campaign is full of operational problems that translate readily to the tabletop or campaign map: overstretched supply lines, unreliable intelligence, cavalry exploitation, command rivalry, exhausted formations, vulnerable flanks and armies whose apparent numerical strength often bears little relationship to their actual fighting effectiveness. Warsaw itself is fascinating precisely because the outcome cannot be explained simply by comparing numbers.

Warsaw 1920 is therefore an excellent introduction rather than the final word on its subject. Zamoyski writes exceptionally well, handles operational movement with clarity and succeeds in making a complicated and often neglected campaign understandable. Its principal weakness is that the very brevity which makes it so readable also prevents it from exploring some of the political, social and strategic questions raised by its own argument.

I finished it wanting considerably more detail, particularly about the wider political consequences and the experiences of the peoples caught between the competing Polish and Soviet projects. That is a criticism, but perhaps also a recommendation. A poor introductory history leaves the reader thinking that there is nothing more worth knowing. Zamoyski’s leaves you wanting to find a much larger book on the subject. I enjoued it.
