Plagued by their internecine competition, poor coordination, and bad communications, Russian forces suffered great casualties through inadvertently shelling, bombing, and shooting each other. None of this altered the ultimate outcome, when after weeks of rooftop, cellar, house-to-house, and street barricade fighting, Chuikov’s army reached the city center and invited negotiations for surrender. German emissary General Hans Krebs’s delegation brought news of Hitler’s suicide, but they either could not or would not meet the surrender deadline set by the Russians. Chuikov ordered a punitive resumption of artillery and rocket bombardment, bringing further devastation on the wretched citizenry.
