In the history of the Unknown War, Leningrad stands out as a symbol of the courage and persistence of the Russian people. For years, Leningrad resisted capture by Hitler's forces. In the aching cold of winter, with nothing to eat, hundreds of thousands of Leningraders perished from starvation or simply froze to death. Still they fought on. During the terrifying siege, which the Russians call "The 900 Days", Nazi troops encircled the city and cut off all communications - but Leningrad would not surrender.
