When Eagles Fall: The 1939 Campaign That Changed the World: World War 2

By Ivo Vichev

On 1 September 1939, German guns opened fire on a small Polish garrison at Westerplatte. Within weeks, Poland lay crushed between two totalitarian powers—and the world had crossed the threshold into a new kind of war.

When Eagles Fall: The 1939 Campaign That Changed the World tells the story of September 1939 not as a brief prelude to World War II, but as a decisive turning point in its own right: a brutal laboratory in which blitzkrieg, terror bombing, and the collapse of collective security were all tested and proven.

Historian and narrative storyteller Ivo Vichev takes the reader from the first shells crashing into Westerplatte and the desperate cavalry counter-attacks near Krojanty, through the Bzura counter-offensive and the siege of Warsaw, to cabinet rooms in London and Paris, the Kremlin in Moscow, and uneasy debates in Washington and Tokyo.

On every front, the same questions emerge:

• Why did Poland stand so largely alone?
• Why did the guarantees of the great powers fail when they were needed most?
• How did the fall of one country redraw the strategic and moral map of the entire world?

Drawing on diaries, intelligence reports, diplomatic correspondence and post-war testimony, When Eagles Fall restores Polish soldiers, civilians and statesmen to the centre of the story. It shows how their decisions, sacrifices and defeats shaped the war that followed—and why the lessons of 1939 still matter in an age of renewed aggression, territorial revisionism, and contempt for international law.

This book is for readers who enjoy:

• World War II history told through people, not just dates;
• Deep yet accessible analysis,
• Military and diplomatic history woven into a single narrative.

In a campaign that lasted only weeks, the world learned how quickly a modern state could be destroyed—and how slowly democracies responded when faced with ruthless, well-prepared aggression.

When Eagles Fall is a powerful reminder that the first campaign of the Second World War was also one of its most important—and that its warnings have never been more relevant.

I was born in Varna, Bulgaria, on the edge of the Black Sea – a place where history is never really "past". Growing up between old empires and new borders, I was surrounded by stories of wars, occupations, disappearances and sudden changes of flag. Later I moved to Warsaw, Poland, where I studied history and public relations at the Polish Academy of Sciences (PAN). Warsaw is a city built on ruins and memories, and it forced me to ask one question over and over again: Why is so much of our most important history told in the most boring way possible? From dry facts to living stories Like every history student, I spent endless hours buried in heavy academic books – dates, treaties, footnotes stacked on footnotes. I respected the work, but I often felt like the life had been drained out of the events themselves. That changed when I discovered Ryszard Kapuściński. His books had that rare tone I'd been searching for: history and politics told through people, scenes and atmosphere. It was factual, but it breathed. From that moment I knew what I wanted to do: take serious history and tell it with the clarity and tension of a documentary – so future generations don't have to suffer through dead, lifeless books to understand the past. What I write about My books focus on the places where power is most visible – and most hidden: Wars and battles Espionage and cyber conflict Country histories Some books are big, sweeping national histories. Others zoom in on a single battle, uprising or covert operation. All of them try to answer the same question: What really happened here, and what does it mean for the people who had to live through it? How I tell history If you read my books, you can expect narrative, scene-by-scene storytelling – not just lists of dates. Serious research from archives, memoirs, official reports and investigative journalism. Clear explanations of complex events like cyberattacks and proxy wars. And a refusal to simplify messy, uncomfortable truths. I don't write official history. I don't write propaganda. I write stories that are honest, human and readable – the kind of books I was always looking for as a student and rarely found. If you care about how we got from trenches and partitions to cyberwar and drone strikes – and you don't want to fall asleep over another textbook – I wrote these books for you.

Chapter 1: Europe on the Precipice

A late-night train from Berlin to Warsaw pulled out on August 31st, 1939, its whistle cutting through the humid air like a premonition. Among the passengers clutching their belongings in the dimly lit compartments sat Józef Lipski, Poland's Ambassador to Germany, returning from what he knew was his final diplomatic mission to the German capital. His weathered hands trembled slightly—not from the train's motion, but from the weight of his failed meeting with Ribbentrop, conducted just hours earlier at the German Foreign Ministry.

Lipski stared out at the German countryside rolling past in the darkness, each mile carrying him toward a homeland that might not exist much longer. In his briefcase lay the crumpled notes from his meeting: the return of Danzig, extraterritorial highways through the Polish Corridor, the reduction of Poland to a vassal state. The same impossible demands, now presented as Europe's final offer of peace.

Three hundred miles to the east, in a modest farmhouse near the Polish border, Maria Kowalska was teaching her eight-year-old son to fold the family's important papers into a small leather satchel. Just in case we need to leave quickly, kochanie, she whispered, not wanting to frighten him, but knowing that farmers' wives had learned such lessons during the Great War. Her husband was already at the local mobilisation centre, along with every other man between eighteen and forty. The fields stood ready for harvest, but there might be no one left to bring them in.

Twenty-one years had passed since Poland had risen from the grave of empires. Now, as Lipski's train carried him through the German darkness toward an uncertain dawn, those years felt like borrowed time—a brief reprieve in the eternal struggle between Germany's hunger for expansion and Poland's determination to survive.

The grim situation facing Polish diplomats was rooted in the bitter soil of Versailles, where the seeds of this crisis had been planted twenty years earlier. Allied statesmen had gathered in the Hall of Mirrors to redraw the map of Europe, carving Poland from the corpse of three empires and creating what Lloyd George later described as an almost impossible problem—a corridor of largely Polish territory that separated East Prussia from the German mainland, granting the new nation access to the Baltic Sea through the ancient Hanseatic city of Danzig.

When Foreign Minister Hermann Müller signed the treaty on June 28, 1919, German delegates were close to tears. Marshal Foch, watching from the Allied side, famously warned that this was not peace, but an armistice for twenty years. His prophecy was proving grimly accurate. The Polish Corridor had become the focal point of German rage and Polish pride—to Germans, an intolerable wound, to Poles, the lifeline of their independence.

That wound had festered through two decades of German resentment and Polish determination. In the beer halls of Munich and the cafés of Berlin, politicians of every stripe railed against the Diktat of Versailles. When a failed Austrian painter named Adolf Hitler first climbed onto a table in a Munich beer hall in the early 1920s to denounce the November criminals who had signed the armistice, few took him seriously. But economic collapse has a way of making extremists seem reasonable, and by 1932, Hitler's message of national resurrection was resonating with millions of desperate Germans.

President Hindenburg's fatal miscalculation came on January 30, 1933, when he appointed Hitler Chancellor, believing the upstart could be controlled. One of Hindenburg's advisers, Vice-Chancellor Franz von Papen, boasted that they had hired Hitler and that in a few months they would push him so far into a corner that he would squeal. Within months, Hitler had transformed the German state into an instrument of his will, and the machinery of democracy lay in ruins.

The secret rearmament programme that followed was impossible to hide completely from Poland's intelligence services, among Europe's most effective. German factories producing tractors began turning out tanks. Flying clubs became training grounds for the Luftwaffe. When German troops marched into the demilitarised Rhineland in March 1936, Foreign Minister Józef Beck knew the post-war order was crumbling.

Hitler would later tell his generals that those forty-eight hours were among the most nerve-wracking of his life—had France mobilised, he would have been forced to withdraw in humiliation. But the Western democracies did nothing, paralysed by their own exhaustion and delusions about German intentions.

Polish diplomats understood the implications all too well. One of Beck's aides later recalled the mood in Warsaw: if Hitler could seize the Rhineland without consequence, what would stop him from doing the same in Austria, Czechoslovakia—or Poland itself? The answer came brutally swiftly. On March 12, 1938, German troops crossed the Austrian border to cheering crowds, and Hitler stood on the balcony of the Hotel Imperial in Vienna, tears streaming down his face as he proclaimed the Anschluss. Germany now surrounded Polish territory on three sides, tightening the noose with methodical precision.

The Czechoslovak crisis that followed revealed the true bankruptcy of Western policy. When Hitler began demanding justice for the Sudeten Germans in spring 1938, Czechoslovakia seemed better positioned to resist than Austria had been. The Franco-Czech alliance obliged France to intervene, the Czech army was well-equipped and motivated, and the Soviet Union had indicated its willingness to support Prague—provided France honoured its obligations first.

But Prime Minister Neville Chamberlain had convinced himself that another European war could be avoided through reasonable negotiation with reasonable men. At sixty-nine, the Birmingham businessman turned politician bore the scars of witnessing the Great War's slaughter from the home front. His half-brother had been wounded at the Somme; his cousin had died at Passchendaele. Like millions of his generation, Chamberlain was determined that such carnage must never be repeated—even if it meant sacrificing smaller nations for the illusion of peace.

The crisis reached its climax when Chamberlain made three unprecedented flights to Germany. At their first meeting in Berchtesgaden, the Prime Minister emerged convinced that Hitler was a man who could be relied upon when he had given his word. But at Bad Godesberg, Chamberlain's confidence wavered as Hitler's demands escalated before his eyes. The Führer sat rigid in his chair, his pale eyes blazing with manufactured fury, his voice rising to that familiar shriek: I am sorry, but that is no longer enough!

The final act played out in Munich on September 29, where Chamberlain, French Premier Daladier, Mussolini, and Hitler carved up Czechoslovakia without Czech participation. As the four leaders signed the agreement in the early hours of September 30, transferring the Sudetenland to Germany, Chamberlain clutched the separate piece of paper promising Anglo-German cooperation like a lifeline.

He returned to London waving that scrap of paper before ecstatic crowds at Heston Airport, declaring from 10 Downing Street that he had achieved peace for our time. In Warsaw, Beck was less impressed. British policy already looked, in Churchill's later phrase, like feeding a crocodile in the hope it would eat you last. Within six months, Hitler had devoured the rest of Czechoslovakia, making clear that his ambitions extended far beyond reuniting ethnic Germans.

Hitler's destruction of Czechoslovakia finally shattered even Chamberlain's capacity for self-deception. On March 31, 1939, the Prime Minister stood before the House of Commons, his hands visibly shaking as he announced that Britain would guarantee Polish independence. In the event of any action which clearly threatened Polish independence, he declared, His Majesty's Government would feel themselves bound at once to lend the Polish Government all support in their power.

The guarantee electrified British public opinion, which had finally turned decisively against Nazi Germany. In Polish cities, crowds gathered in the streets to cheer the news, seeing in it the promise of salvation from the German threat. But the guarantee was also strategically awkward. Britain had no land border with Poland, the Royal Air Force lacked the range to strike meaningful targets from British bases, and the British Army remained small by continental standards compared to France and Germany.

Most crucially, the guarantee forced Britain to rely on Soviet cooperation, and Stalin was not inclined to save capitalism from fascism without extracting a heavy price. Beck himself understood these contradictions all too well. Poland had barely survived Lenin's attempt to export revolution westward in 1920, stopping the Red Army at the gates of Warsaw in what Poles called the Miracle on the Vistula.

When the British Ambassador pressed him on accepting Soviet military assistance, Beck made his position clear: Poland welcomed British friendship but would not accept Soviet troops on its soil in exchange. After 123 years of partitions, he argued, Poland had not regained independence in order to become a Soviet satellite.

Hitler's response to the Anglo-French guarantee came swiftly and with characteristic venom. On April 28, 1939, he appeared before a packed Reichstag, uniformed party officials raising their arms in rigid salute as the Führer worked himself into familiar fury. His pale face flushed with rage, spittle flying as his voice rose to that piercing shriek that echoed from the marble walls: England today is governed by men who are not of the people! But it was his denunciation of the German–Polish Declaration of Non-Aggression that sent real chills through European chancelleries.

The Free City of Danzig had become the perfect powder keg. The city's 400,000 inhabitants were overwhelmingly German in sympathy but economically dependent on Polish trade through the vital port facilities. By 1939, the Danzig Nazi Party controlled the city senate and was systematically dismantling democratic institutions. Storm troopers now paraded through streets where the Hanseatic League had once held sway, their jackboots echoing ominously on ancient cobblestones.

For families like the Kowalski’s, the Danzig crisis meant more than diplomatic abstractions. Maria's brother worked as a dock supervisor in the port, one of thousands of Poles whose livelihoods depended on access to the sea. In her village, people whispered about what would happen if the Germans seized the city completely. First Danzig, her neighbour warned while they hung laundry in the morning sun, then the whole Corridor, then what's left of us?

Carl Jacob Burckhardt, the Swiss diplomat serving as League High Commissioner, found himself increasingly isolated as he tried to maintain the fiction of international authority. He later wrote that he felt he was watching the collapse of civilisation and was powerless to stop it. Gauleiter Forster spoke of historical injustice and the bleeding wound of German separation; Burckhardt cited international law and treaty obligations. Neither convinced the other.

Beck's public response was defiant but privately realistic: Poland wants peace, but Poland fears no one. We are not going to provide Germany with a free road to the east at our expense. The rhetoric was brave, but military realities were sobering. Poland possessed one of Europe's larger armies, but still relied heavily on horse-drawn transport, its air force equipped with obsolescent aircraft, its strategic position growing more desperate by the day.

As the Danzig crisis deepened through that fateful summer, Europe's statesmen turned their attention toward Moscow, where Joseph Stalin held the key to peace or war. The Georgian bank robber turned revolutionary was being courted simultaneously by both sides, his pocked face betraying no emotion as he weighed his options with characteristic patience and cunning.

In the Baltic capitals of Riga, Tallinn, and Kaunas, foreign ministers watched the Moscow negotiations with growing alarm. If Stalin aligned with the West, Soviet troops might march through their territories to reach Poland. If he aligned with Hitler, they might disappear entirely from the map. As one Baltic foreign minister later remarked, they felt caught between the hammer and the anvil, with both about to fall.

The British and French missions that arrived in Moscow in August 1939 were doomed before they began. The Western powers wanted Soviet military support without offering Stalin the territorial concessions he demanded in return. Most fatally, they refused to pressure Poland into accepting Red Army troops on Polish soil—the essential prerequisite for any effective Soviet intervention.

Marshal Voroshilov's question cut to the heart of the matter with devastating logic: How can we help Poland if Poland will not let our armies cross its territory to engage the Germans? The Polish position was understandable but ultimately suicidal. Beck's stance remained inflexible: Poland would fight Germany alone, if necessary, but would never voluntarily surrender its sovereignty to purchase foreign aid.

While the Western allies debated and Poland remained intransigent, Hitler was making Stalin an offer he could hardly refuse: a free hand in Finland, the Baltic states, and eastern Poland in exchange for Soviet neutrality. For Stalin, whose massive purges of 1937-38 had decimated the Red Army's officer corps, neutrality offered precious time to rebuild his shattered military while the capitalist powers bled each
