Was just skimming Anna Reid’s new book, Leningrad: The Epic Siege of World War II, 1941-1944 (Walker & Co. 2011), and on pp. 274-275 found this passage re: the partial evacuation of the city in early 1942:
“…Diarists describe queuing for hours for soup, being unable to find anywhere to sleep, and fighting for places on the trains onwards through unoccupied Russia. Nor, when food was available, were measures initially taken to prevent the starving from killing themselves by overeating. A doctor ordered to set up a medical station at Zhikharevo discovered that evacuees were immediately eating all the dry rations - smoked sausage and bread - given them for the three-day journey onward to Tikhvin, and bursting their stomachs… Having described the results of his autopsies he persuaded [Soviet officials] that evacuees should instead be fed in small quantities en route, with millet and semolina cooked in the train boilers.”
The story comes originally from Ales Adamovich and Daniil Granin, A Book of the Blockade (Hilda Perham, Moscow 1983), pp. 435-438.
