Warsaw, Poland's proud capital, fell to German troops on October 1, 1939, after a brutal one-month siege. The city, once a vibrant hub of culture and politics, lay in ruins as German artillery and airpower proved too strong for the valiant Polish defenders. As the Polish army fought bravely, they were vastly outnumbered and outgunned, and eventually, Warsaw's surrender marked a devastating blow to Poland's sovereignty. The fall of Warsaw was a crushing defeat for Poland and paved the way for Germany's occupation of the country, plunging Europe into the darkness of World War II.
