The Pirie Report is a first-class evaluation of the secret activities of the British in Greece during the early stages of World War II and the Occupation (1940-1942), that is from the Italian invasion to the blowing up of the Gorgopotamos bridge in late 1942.

Through the pages of the Pirie Report, we follow Greece's journey from the pre-war period, through the war and the Occupation. The Report immerses the reader in the atmosphere of the Occupation, with its prohibitions and dangers, but also the optimism and hidden hopes behind the code names, secret words, and covert operations.

It is a highly significant primary source for historians and political scientists – as well as an excellent read for the general public interested in delving into the conditions of World War II in Greece and the dilemmas of British policy during the period, offering a piece of knowledge to Greeks who want to understand how foreign powers perceived their country.

The Pirie Report differs from classic academic analyses because it provides the reader with field information and leaves them to evaluate it indefinitely. It does not simply convey the mood to the reader. The reader experiences the atmosphere through an exciting espionage-political-historical narrative.
