Book excerpt: Following the Italian invasion of Albania, the British government was worried that Greece would be next. Their Intelligence Service in Athens prepared to sabotage their plans, stored explosives and trained saboteurs. When Germany came to Italy's aid, they took control of Greece, despite attempts to sabotage the road and rail links. This book investigates the success and failures of British, American and Greek sabotage missions, the attacks on the Gorgopotamos and Asopos viaducts, on roads, railways, shipping and mining operations. Using contemporary documents from the CIA and National Archives, biographies and autobiographies, it provides first-hand accounts from those involved, those who masterminded the operations and the reports of the agents infiltrated by boat, submarine or plane. It has also used historians' accounts found on websites to provide a detailed history of sabotage in Greece between 1940 and liberation in 1944.
