This book studies the history of diplomatic and security relations between Ireland and Britain, in the early period of the modern troubles, 1966 1974. Looking at the wide variety of relations and the deep trust evidenced by cooperation in the 1960s, Craig shows for the first time the context of Common Market and trade negotiations in which Anglo-Irish relations crystallized in the era of Lemass.

As Anglo-Irish relations change, so too does the nature of the book. Once the first British soldiers are killed, and following the deaths of so many civilians on Bloody Sunday, joint entry to Europe became little more than an afterthought. Thus, new research on the attempts by Britain to gain security and intelligence cooperation with the Republic alter previous judgements of how the Republic reacted to the emergence of the Troubles. Despite the Sunningdale Agreements, this book shows that after 1974 both Britain and Ireland began secretly and separately to prepare for the collapse of Northern Ireland into factional conflict and a political abyss. Through an examination of the Arms Crisis, internment, cross-border security, the Irish government s doomsday plans, and Britain s security and intelligence policies and is the impact of the Provisional IRA s electricity sabotage campaign in 1971.
