British Intelligence is the oldest, most experienced organization of its kind in the world, the unseen hand behind so many world events, and glamorized by James Bond. Despite the change in role, from a global power controlling an Empire that covered much of the world, to a mere partner in the North Atlantic Treaty Organization (NATO) and the European Union, the country’s famed security and intelligence apparatus continues largely intact, and recognized as “punching above its weight.” Feared by the Soviets, admired and trusted by the Central Intelligence Agency (CIA), British Intelligence has provided the hidden dimension to the conduct of domestic and foreign policy, with the added mystique of Whitehall secrecy, a shroud that for years protected the identities of the shadowy figures who recruited the sources, broke the codes, and caught the spies.This second edition of Historical Dictionary of the British Intelligence covers the history through a chronology, an introductory essay, appendixes, and an extensive bibliography. The dictionary section has over 1,000 cross-referenced entries on specific operations, spies and their handlers, the moles and defectors, top leaders, and main organizations. This book is an excellent access point for students, researchers, and anyone wanting to know more about the British Intelligence.
