The Baghdad Set: Iraq through the Eyes of British Intelligence, 1941-1945. London/Cham: Palgrave Macmillan/Springer Nature, 2019. ISBN 9783030151829.
This book provides the first ever intelligence history of Iraq from 1941 to 1945, and is the third and final volume of a trilogy on regional intelligence and counterintelligence operations that includes Nazi Secret Warfare in Occupied Persia (Iran) (2014), and Espionage and Counterintelligence in Occupied Persia (Iran) (2015). This account of covert operations in Iraq during the Second World War is based on archival documents, diaries, and memoirs, interspersed with descriptions of all kinds of clandestine activity, and contextualized with analysis showing the significance of what happened regionally in terms of the greater war. After outlining the circumstances of the rise and fall of the fascist Gaylani regime, I examine the activities of the Allied secret services (CICI, SOE, SIS, and OSS) in Iraq, and the Axis initiatives planned or mounted against them. I emphasize the social nature of human intelligence work and introduce the reader to a number of interesting, talented personalities who performed secret roles in Iraq, including the distinguished author Dame Freya Stark. ‘O’Sullivan has found a completely underexplored but important field and made it entirely his own. With a strong cast and exciting narrative, The Baghdad Set bears all the hallmarks of his well-crafted prose and exhaustive research, with a wonderful awareness of the secondary literature and an unrivalled mastery of the primary material.’ Ashley Jackson (Professor of Imperial and Military History, King’s College London, UK).
Espionage and Counterintelligence in Occupied Persia (Iran): The Success of the Allied Secret Services, 1941-1945. Basingstoke: Palgrave Macmillan, 2015. ISBN 9781137555564.
Nominated for The 2016 Cundill Prize in Historical Literature. A companion to the pioneering Nazi Secret Warfare in Occupied Persia (Iran), which told of Germany’s spectacular failure in the region, this carefully researched study of British, American, and Soviet success makes for fascinating reading. Espionage and Counterintelligence in Occupied Persia (Iran) introduces us to Allied and Axis spies, spycatchers, and spymasters and to the highly effective methods employed by regional security forces to safeguard the lines of communication, the Lend-Lease supply route from the Gulf to the Caspian, and the vital oilfields, pipelines, and refineries of Khuzistan from Nazi attack and indigenous sabotage. Of particular interest in this study of neglected operational narratives and key clandestine personalities is its lucid description and analysis of Anglo-American and Anglo-Soviet intelligence relations, as the three Allies moved inexorably towards postwar realignment and the Cold War. ‘Eminently readable. Adrian O’Sullivan is an excellent writer, whose lively and elegant style succeeds in capturing the narrative and the ironies of its twists and turns in a way that is highly entertaining without “dumbing down”.’ Tilman Dedering (University of South Africa)
Nazi Secret Warfare in Occupied Persia (Iran): The Failure of the German Intelligence Services, 1939-1945. Basingstoke: Palgrave Macmillan, 2014. ISBN 9781137427892.
The first full-length work to be published about the spectacular failure of the German intelligence services in Persia (Iran) during WWII. Based on my doctoral research, it analyzes a compelling history of Nazi planning, operations, personalities, and intrigues, and follows the protagonists from Hitler’s rise to power into the postwar era. ‘Well worth reading … the ultimate book on German secret-service activity in Persia from 1939 to 1945.’ Martin Moll (University of Graz)
