Description

A volume of reports, memoranda, and correspondence from the Joint Intelligence Sub-Committee (JIC). The JIC was formed of representatives from the intelligence services, the armed services, and the Foreign Office. Its purpose was to assess military, security, and foreign policy requirements and coordinate Britain’s intelligence organisations accordingly. The JIC members discussed a vast range of international and domestic issues in their meetings. In this file, subjects documented include the need to gather intelligence on the Soviet threat to the Middle East; minutes of the Anglo-French-Soviet staff conferences in 1939; assessment of enemy military strength and intentions for 1940; the organisation of intelligence gathering and scientific research; propaganda in Libya and Ethiopia; German propaganda; the strength and equipment of German armed forces; enemy production capabilities; assessment of possible German invasions of the United Kingdom, Holland and Belgium, Hungary and Romania; and a report on potential German fifth-columnist activities in the U.K.
