Significance

The Vienna offensive, conducted by the Soviet 2nd and 3rd Ukrainian Fronts between 16 March and 15 April 1945, resulted in the capture of Vienna on 13 April 1945. The operation brought one of Central Europe's major capitals under Soviet control in the final weeks of the war on the Eastern Front, extending the Red Army's reach deep into Austria. German forces numbering 270,000 faced a Soviet force of over 1.1 million, and the disparity in scale contributed to a German casualty toll of approximately 30,000 against Soviet losses of nearly 168,000—figures that reflect the intensity of the urban combat required to secure the city. The fall of Vienna eliminated a significant defensive anchor on Germany's southeastern flank and further compressed the shrinking perimeter of German-held territory as Allied forces closed from multiple directions in the war's closing phase.

Tactics

After several days of street-to-street fighting, Soviet troops secured Vienna on 13 April 1945. The overview does not describe specific maneuvers, terrain use, or unit dispositions beyond this characterization of urban combat.
