On September 1, 1939, Adolf Hitler's Nazi Germany launched a surprise attack on western Poland, shattering the fragile peace in Europe and plunging the continent into the darkness of World War II. This bold move marked the first major military operation of the war, and it would have far-reaching consequences for Poland, Germany, and the world at large.
In the years leading up to the invasion, Germany had been making aggressive overtures towards Poland, claiming that the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany, was rightfully theirs. Meanwhile, Hitler had been secretly negotiating with the Soviet Union, and on August 23, 1939, the two powers signed the Molotov-Ribbentrop Pact, a non-aggression treaty that included a secret protocol dividing Eastern Europe into Soviet and German spheres of influence. Poland, trapped in the middle, was about to become the first casualty of this new alliance.
At 4:45 am on September 1, 1939, the German army, led by General Heinz Guderian, launched a devastating assault on western Poland. The Poles, caught off guard, were quickly overwhelmed by the German Blitzkrieg (lightning war) tactics, which combined air power, armor, and rapid infantry advances to break through enemy lines. By the end of the day, German forces had advanced over 20 miles into Polish territory, and the Polish air force had been destroyed.
On September 17, 1939, the Soviet Union, honoring its secret pact with Germany, invaded eastern Poland, capturing the city of Lvov and meeting up with German forces near the town of Brest-Litovsk. The two powers then divided Poland between them, with Germany annexing western Poland and the Soviet Union occupying eastern Poland.
The international community was shocked and outraged by Germany's aggression, and on September 3, 1939, France and the United Kingdom declared war on Germany, followed by Canada, Australia, and New Zealand. The United States, still maintaining its isolationist policy, did not enter the war until December 1941, after the Japanese attack on Pearl Harbor.
The annexation of western Poland by Germany had far-reaching consequences, including:
One of the most poignant accounts of the invasion comes from Polish Colonel Jan Kierzek, who wrote in his diary: "The sky is black with German planes... Our soldiers are fighting bravely, but they are no match for the enemy's modern tanks and aeroplanes."
Here are the key dates and events surrounding the annexation of western Poland:

The annexation of western Poland by Germany marked the beginning of a dark chapter in world history, and its consequences would be felt for decades to come. As we reflect on this pivotal event, we are reminded of the importance of international cooperation and the need for vigilance in the face of aggression.
Historians have long debated the motivations behind Hitler's decision to invade Poland. Some argue that it was a deliberate attempt to provoke a war with the West, while others believe it was a calculated move to secure Lebensraum (living space) for the German people. Recent scholarship suggests that Hitler's vision of a Thousand Year Reich was a key driver of his foreign policy, and the invasion of Poland was a crucial step towards achieving this goal.
Another area of contention among historians is the role of the Molotov-Ribbentrop Pact in the lead-up to the invasion. While some view it as a cynical attempt to divide Eastern Europe into Soviet and German spheres of influence, others argue that it was a necessary evil to prevent a two-front war.
The historiographical consensus, however, is clear: the invasion of Poland marked a turning point in European history, precipitating a chain of events that would lead to the devastation of World War II.
Colonel Jan Kierzek, whose diary entry was cited earlier, was a career military officer who fought bravely against the German invasion. Despite being vastly outnumbered and outgunned, Kierzek's unit held out against the German army for several days, inflicting significant casualties.
Kierzek's personal bravery and leadership during the invasion earned him a promotion to General, and he went on to play a key role in the Polish resistance movement throughout the war.
In the aftermath of the war, Kierzek became a vocal advocate for Polish-German reconciliation, arguing that forgiveness and understanding were essential for rebuilding a shattered Europe.
The annexation of western Poland by Germany had far-reaching geopolitical implications. The Soviet Union's invasion of eastern Poland, in accordance with the Molotov-Ribbentrop Pact, created a buffer zone between Germany and the Soviet Union, setting the stage for a decades-long Cold War rivalry.
The international community's response to the invasion, marked by France and Britain's declaration of war on Germany, underscored the complexity of European alliances and the fragility of the Treaty of Versailles.
The invasion also had significant implications for the global balance of power, marking the emergence of Germany as a dominant military power in Europe and paving the way for the United States' rise as a global superpower.
The annexation of western Poland by Germany was a classic example of aggressive expansionism, driven by a toxic mix of nationalism, militarism, and racist ideology.
Hitler's decision to invade Poland was motivated by a desire to reverse the Treaty of Versailles, which he saw as an affront to German national honor and a constraint on Germany's rightful place in the world.
The invasion also highlighted the failure of the League of Nations, established after World War I to prevent future conflicts, and underscored the need for more robust international institutions and collective security arrangements.
The Molotov-Ribbentrop Pact, signed on August 23, 1939, is one of the most significant documents of the 20th century. The pact's secret protocol, which divided Eastern Europe into Soviet and German spheres of influence, was only discovered after the war and remains a testament to the cynicism and opportunism of the two totalitarian regimes.
The German army's invasion plans, code-named "Fall Weiss," were meticulously detailed in a series of documents and memoranda, highlighting the military's operational efficiency and Hitler's micromanagement style.
The Polish government's diplomatic correspondence with its allies, including France and Britain, provides valuable insights into the diplomatic maneuvering and failed attempts to prevent the war.
