Description

A volume of reports commissioned for the Joint Intelligence Sub-Committee (JIC). The JIC was formed of representatives from the intelligence services, the armed services, and the Foreign Office.

A vast range of international and domestic issues are investigated and analysed in the JIC’s reports. Subjects covered in this file include the results of Allied bombing raids in Europe; Allied strategy in South East Asia; the possibility of an internal German collapse, and the Allied response to this; enemy sabotage in Britain and the Mediterranean; preparations for Operation Overlord, including calculations of probable enemy resistance, deception and distraction arrangements, and the possibility of the Germans using chemical weapons; post-war Soviet foreign policy and relations with Britain; Allied cypher security; support for European anti-Nazi resistance movements; and Axis military strength and casualties.
