At the outbreak of WWII Britain put into motion the strategy of using the Royal Navy to blockade Germany, depriving her of essential goods. When Europe fell the blockade was widened to include all of Europe.

This provided a dilemma for the British, the Ministry of Economic Warfare was in favour of depriving all occupied countries of goods, for the Foreign Office depriving occupied countries would mean negatively affecting countries that were allied with Britain.

In Greece this would lead to famine, and a relief operation organised by the International Red Cross.
