Operational Intelligence Centre was the nerve centre of the British Admiralty in World War II, dedicated to collecting, analysing and disseminating information from every possible source which could throw light on the intentions and movements of German naval and maritime forces. OIC laboured tirelessly, despite early disappointments, to supply the Navy and RAF with the intelligence that would enable them to defeat Hitler and his admirals. Patrick Beesly, an insider drawing on considerable personal knowledge, reveals, in full, the compelling story of OIC. He throws light on dramatic episodes such as the hunt for the Bismarck; the tragedy of Convoy PQ17; the long war against the U-boats; and on many other significant events critical to the course of the war. Very Special Intelligence, here presented with a new Introduction which sets the work in context and takes account of new research, is the fascinating story of an organisation which contributed so much to Allied success.
