ゼーロウ高地
As result of the 1st Belorussian Front's success at the Seelow Heights and the Oder Front in general, most of the forces of the German 9th Army were encircled before they could retreat to Berlin. The city was then defended by broken formations, the "Volkssturm", police, and air defence units, which resulted in the Red Army taking it in 10 days.
