British attempts "to starve" Germany were largely unsuccessful. In 1937/38 Germany's own supply from domestic sources constituted 89% of grain, 90% of milk and dairy products, 95% of meat, 74% in fish and 79% of eggs. German agriculture had been fully mobilised by the Nazi leadership, haunted by memories of the blockade of Germany in World War I and later was able to maintain per capita foodstuff supplies to 1942, after which there was a steady deterioration in both the quality and quantity of the civilian ration.
