How Warsaw held off the German Wehrmacht for nearly a month in 1939
When German forces invaded Poland in September 1939, they expected a swift collapse of the capital. Instead, Warsaw mounted a desperate, improvised defense that repelled elite Panzer divisions and held out for weeks. The city’s survival relied on civilian ingenuity, makeshift barricades, and a refusal to surrender until the very end.
The siege began on September 8, 1939, after German armored units reached the city's outskirts. Under the command of General Walerian Czuma, the defense was initially skeletal, consisting of only four infantry battalions and a single artillery battery. To stabilize the city, Stefan Starzyński, the Civilian Commissar, mobilized residents to construct barricades and anti-tank barriers. This civilian effort, combined with the arrival of retreating military units, eventually allowed the defenders to muster the equivalent of two infantry divisions.
The defense was marked by tactical creativity. When conventional weapons were scarce, defenders used unconventional methods, such as igniting turpentine from a local factory to destroy German tanks. During the initial assault on the western borough of Ochota, Polish forces successfully repelled the 4th Panzer Division, which lost approximately 80 of its 220 tanks. This resistance forced the German high command to divert resources, buying critical time for other Polish units.
As the siege intensified, the Luftwaffe initiated an unrestricted bombardment campaign, targeting hospitals, schools, and water works to break the city's morale. By September 25, a day known as 'Black Monday,' the intensity of the air and artillery strikes reached a peak. With the water supply destroyed, food running out, and no support from Western Allies, the situation became untenable. On September 28, the garrison officially capitulated, and approximately 140,000 Polish troops were taken prisoner.
The human cost was immense, with about 18,000 civilians perishing during the siege. Beyond the loss of life, the city suffered catastrophic structural damage, with 10% of buildings entirely destroyed and another 40% heavily damaged. The German occupation that followed lasted until January 17, 1945, when the Wehrmacht finally abandoned the city as Soviet forces advanced.
