Subjects covered in this file include censorship of the British and American press; the possibility of a German invasion of Spain and Portugal; German strategy in the eastern Mediterranean, including the invasion of Crete; the production of rumours designed to undermine German morale; German psychological warfare; the possibility of a German invasion of the Soviet Union; coordination of intelligence with the United States of America; German strategy in North Africa; cover plans for British troop movements; the disruption of trade on the Danube; and the security of intelligence sources.
