Greece suffered terrible privations during World War II as the Germans appropriated most of the country's agricultural production and prevented its fishing fleets from operating. As a result, and because a British blockade initially hindered foreign relief efforts, the Great Greek Famine resulted. Hundreds of thousands of Greeks perished, especially in the winter of 1941–1942. In the mountains of the Greek mainland, in the meantime, several Greek resistance movements sprang up, and by mid-1943, the Axis forces controlled only the main towns and the connecting roads, while a "Free Greece" was set up in the mountains.
