The siege of Warsaw in 1939 was fought between the Polish Warsaw Army (Polish: Armia Warszawska, Armia Warszawa) garrisoned and entrenched in Warsaw and the invading German Army.
It began with huge aerial bombardments initiated by the Luftwaffe starting on September 1, 1939 following the German invasion of Poland. Land fighting started on September 8, when the first German armored units reached the Wola district and south-western suburbs of the city. Despite German radio broadcasts claiming to have captured Warsaw, the initial German attack was repelled and soon afterwards Warsaw was placed under siege. The siege lasted until September 28, when the Polish garrison, commanded under General Walerian Czuma, officially capitulated.
