The Polish resistance movement, including the Home Army and the Polish Underground State, was the largest underground resistance movement in all of German-occupied Europe. Poland did not establish a collaborationist government under German occupation. Several Polish uprisings against Germany broke out, including the Zamość uprising, Iwieniec Uprising, Operation Ostra Brama, Lwów uprising and the Warsaw Uprising. During the latter, SS chief Heinrich Himmler anticipated a total destruction of Warsaw, the capital of the "former Polish nation", which has supposedly "blocked the Germans' road to the east for 700 years". Following the Polish loss in the uprising, Germany carried out the planned destruction of Warsaw in late 1944, and in October 1944, Himmler stated in regards to Warsaw: "The city must completely disappear from the surface of the earth and serve only as a transport station for the Wehrmacht. No stone can remain standing. Every building must be razed to its foundation."
