As the seat of the Bolshevik Revolution of 1917 and a center of Soviet industry, Leningrad was a prime target of Hitler’s Russian invasion. Supported by the Finns, intent on recovering territory they had lost in the Finnish-Soviet Winter war the previous year, Nazi forces rapidly broke through the city’s lines of defense, many cobbled together by its civilian population. This film – which features rarely seen archive footage now digitally restored – explores the Siege of Leningrad, which lasted from 1941 to 1944. It was one of the longest and most destructive sieges in history and one that claimed the most casualties.
