Subjects covered in this file include changes to German strategy after serious defeats in the Soviet Union; a potential invasion of Sardinia; British strategy in North Africa and the Mediterranean; the Japanese shipping situation; German resource deficits; the scale of a potential air attack on Britain; commando raids on the Channel Islands; the world-wide Axis threat; German infra-red technology; the use of chemical weapons in Sicily; German naval intentions; the employment of aliens by British intelligence agencies; preparations for the invasion of Sicily; and the exchanging of intelligence with the Soviets.
