The Battle of Bzura was one of the most important clashes during the September Campaign of 1939. This key event in Polish history took place from September 9-22, representing the largest battle of Poland's defensive war against Nazi Germany.
This confrontation occurred along the Bzura River, northwest of Warsaw. It was a desperate attempt by Polish forces to halt the advance of German armored forces moving towards the capital.

Historical Background of World War II
#The outbreak of World War II in September 1939 was the culmination of rising tensions in Europe. This conflict changed the course of history and had an enormous impact on Poland's fate.
Poland's Situation in September 1939
#Poland found itself in an extremely difficult position on September 1, 1939. German forces crossed the country's borders from three directions: west, north, and south. Polish armed forces, numbering about 950,000 soldiers, faced 1.8 million German soldiers.
The disparity in forces was significant:
| Category | Poland | Germany |
|---|---|---|
| Soldiers | 950,000 | 1,800,000 |
| Tanks | 880 | 2,700 |
| Aircraft | 400 | 2,000 |
The Polish command, surprised by the speed of the German attack, had to quickly react to the changing situation. The "Poznań" Army and "Pomorze" Army, which were supposed to defend the western borders, were forced to retreat towards Warsaw. This maneuver led to the concentration of Polish forces in the Bzura River region, which became the prelude to the largest battle of the September Campaign.
