Answer 1

On the defending side was the Soviet Red Army under Markian Popov. On the other side the German Wehrmacht under Alfred Jodl and the Finnish army under Carl Gustaf Emil Mannerheim.

The only heroes were the inhabitants of Leningrad, who suffered from bombardments, cold and starvation for more then 3 years. Between 670,000 and 1.5 millions died.

""Savichevs died. Everyone died. Only Tanya is left," wrote 11-year-old Leningrad girl Tanya Savicheva in her diary. This diary became one of the symbols of the blockade tragedy and was used as an exhibit at the Nuremberg trials." (Wikipedia, "Saint Petersburg")

David M. Glantz, The Seige of Leningrad, 1941-1944: 900 Days of Terror (Brown Partworks, 2001), describes the three directions of Hitler's Operation Barbarosa: Leningrad, Moscow, Stalingrad and the East Black Sea (Chapter 2: Target Leningrad, p. 21). Germany's Army Group North was under the command of Field Marshall Ritter von Leeb: 18th (led by Colonel-General George von Kuechler) and 16th Army (Colonel-General Ernst Busch) and the 4th Panzer Group (Colonel-General Eric Hoepner). They were against the Soviet Baltic Special Military Region's 8th and 11th armies under Colonel-General F. I. Kuznetsov.

Germany found Finland (as Bulgaria) an ally of convenience. Finland had been trying to avoid being annexed by the Soviets, as had happened to Latvia, Estonia, and Lithuania. It was after the Soviets suffered around 50,000 casualties in an invasion attempt that Hitler was emboldened in his Barbarosa plans. The Finns may have been involved in the attack on Leningrad, but the Soviets had already engaged them first before then. The Red's Baltic fleet had a base called Hango, it was taken from the Finns (Glantz, 19).

Harrison E. Salisbury (The 900 Days: The Siege of Leningrad, De Capo Press, 1969) gives oodles more names and very detailed stories from inside Leningrad.
