Volume VI in the hugely successful Documents on Irish Foreign Policy series explores Ireland's Second World War neutrality through secret wartime documents. The book shows, in readable and gripping detail, how Irish diplomats established and executed the State's neutrality in wartime Europe. Most importantly, it reveals in detail hitherto unknown, the increasingly complex and highly-charged nature of wartime British-Irish relations.

The volume is the most comprehensive account ever published of Ireland's foreign policy during the first years of the Second World War. Published, for the first time, are complete transcripts of the British-Irish defense co-operation talks that took place in late May 1940. It includes full reports on the progress of the war in Europe from Irish diplomats in London, Berlin, Paris, Rome, and Washington.

It also covers such areas as the Russo-Finnish Winter War, the invasion and fall of France, the invasion of Norway, Churchill's rise to power, the Blitz, daily life in Berlin during wartime, and Luftwaffe attacks on Ireland.
