The siege of Warsaw had been heavy with bombardments by the German Luftwaffe. They didn't only target government and military outfits- they struck hospitals, water companies, schools, mostly civilian faculties. Civilian casualties were high, bodies littering the streets, covered in dust from the wreckage of the buildings around them. The German tanks and infantry marched down the streets of Warsaw September 28th. Capitulation of the Polish to Nazi forces after such devastating defeat had been imminent.
