The 872 days of the siege caused extreme famine in the Leningrad region through disruption of utilities, water, energy and food supplies. This resulted in the deaths of up to 1,500,000 soldiers and civilians and the evacuation of 1,400,000 more (mainly women and children), many of whom died during evacuation due to starvation and bombardment. Piskaryovskoye Memorial Cemetery in Leningrad holds half a million civilian victims of the siege alone. Economic destruction and human losses in Leningrad on both sides exceeded those of the Battle of Stalingrad, the Battle of Moscow, or the bombing of Tokyo. The siege of Leningrad ranks as the most lethal siege in world history, and some historians speak of the siege operations in terms of genocide, as a "racially motivated starvation policy" that became an integral part of the unprecedented German war of extermination against populations of the Soviet Union generally.
