Poland’s experience in World War II is among the most sorrowful and strongest in contemporary history. Poland was the initial victim of an international tragedy in the making in 1939 when war erupted and was sandwiched between two rising nations that employed its land as not much more than a stepping stone for their empires. However, amid all the combat and broken pacts, Polish history is also a story of courage, sacrifice, and an unrelenting fight to remain alive.
After the regained independence in 1918, Poland spent the years between the wars trying its best to secure its borders and establish sovereignty. But as the 1930s progressed, dark clouds formed on the horizon. Nazi Germany, led by Hitler, was growing more aggressive on one front, while on the other stretched the Soviet Union under Stalin, waiting for its time, rebuilding its purged military, and waiting for tensions in Europe to reach a boiling point. Both countries viewed Poland as a strategic prize.
Despite efforts to find peace through treaties—Poland had signed non-aggression pacts with Germany and the USSR—the writing was on the wall. The ghastly Munich Agreement of 1938, whereby Britain and France yielded Czechoslovakia to Hitler in a last-ditch effort to forestall a second war, foreshadowed the fact that Poland would be left to defend itself alone.
That horror was consummated on August 23, 1939, when the Soviet Union and Nazi Germany mutually signed a so-called non-aggression pact. To the public, it appeared to be a diplomatic détente. Behind the closed doors, however, the two parties had negotiated to divide Eastern Europe amongst themselves. Poland, sandwiched between them in the middle, was now up for grabs.
Just days later, on September 1, Germany invaded from the west. The war began not with a declaration, but with bombs and tanks. The German troops launched a vicious assault on all fronts, employing Blitzkrieg warfare—rapid, synchronized attacks that included simultaneous bombing by air and quick mobile ground troops. Poland’s military fought valiantly, even winning a few small battles, but it was vastly outnumbered and outgunned.
Then came the second blow. On September 17, Russian troops invaded Poland from the east. The double invasion left the country with no hope. The Polish government was forced to flee, and in early October, the remaining resistance pockets collapsed. The country was split in half—Germany held the west, and the Soviets held the east.
Taken over by the Nazis, Poland was decimated. They attempted to destroy its leadership and culture by killing intellectuals, clergy, and resistance leaders systematically. Jews were ghettoized and subsequently transported to killing centers. In the east, the Soviets carried out mass shootings and deportations, most famously the Katyn massacre, where thousands of Polish officers were killed.
But Poland never quit. Though the nation no longer existed on maps, its citizens produced one of the largest underground resistance movements in Europe. The Home Army carried out sabotage operations, gathered intelligence, and even assisted in breaking the German Enigma code. These efforts kept the flame of national identity alive, even at the worst of times.
Jewish resistance also started from behind bars of despair. The Warsaw Ghetto Revolt of 1943 had Jewish fighters hold up Nazi forces much longer than anyone could have imagined, all against impossible odds. The next year, the greater Warsaw Uprising of 1944 tried to liberate the capital before the Soviet forces’ arrival. The revolt was crushed brutally, and the city was left in ruins. andRedd Army tarried outside and waited.
The war’s conclusion did not bring liberation to Poland. Rather, one occupier was replaced by another. The Soviets put in a communist government, and Poland was behind the Iron Curtain for decades to come. But the resistance’s legacy lived on, inspiring movements that would finally bring freedom in the late 20th century.
The experience of Poland in World War II is one of courage and tragedy. It is a bitter lesson in appeasement, the savagery of totalitarian regimes, and the indomitable spirit of a nation that could not be persuaded to yield its identity. It is a lesson for soldiers and for historians: a powerful lesson of what happens when nations are left vulnerable—and of how persistence can alter history.
