A file of signals intelligence reports, messages, and correspondence issued by the Government Code and Cypher School and sent by the head ('C') of the Secret Intelligence Service (MI6) to the Prime Minister, Winston Churchill. This file includes the following reports on Western Europe: that the 86th Corps expresses appreciation for the unusual sight of German Air Force (GAF) aircraft supporting its troops, on July 11; that the 1st Panzer Corps expects an Allied attack north of Maltot, on July 12; that fuel shortages hamper the recovery of crashed aircraft in France, on July 13, with additional fuel being requested; and that the Germans suspect preparations for Allied landings in southern France following Allied air raids on the Mediterranean coast and the Rhone estuary and a build-up of Resistance forces around the Valence area, on July 12; on Southern Europe: that the 5th Mountain Division withdraws to a line between Pergola and Fabriano during the night of July 12/13; and that anti-aircraft units in Italy were ordered on June 22 to always keep optical equipment with their guns, particularly when equipment was transferred as the obtaining of new optical equipment was now impossible following the transfer of the optical industry; on the Russian Front/Denmark: that the 25th Panzer Division, last located in the southern Soviet Union in mid-June, was located at Hobro in Northern Denmark by July 12; Naval Headlines; from the Turkish ambassador in Vichy, a report of July 3 following talks with an authoritative German commander on the state of the war in France, stating that the Germans were suffering greatly from constant Allied air attacks against their road and rail communications, and that no military solution was possible for either side so the war would have to be ended by diplomatic means; from the French delegate in Moscow, a report of July 7 to Algiers on the talks on June 25 between the U.S. ambassador, Harriman, and Ilya Ehrenburg, including references to de Gaulle and the French government in exile in Algiers; and Secret Intelligence Service (SIS) Central Department report number 229 of July 12 which referred to a party to celebrate the V-1 attacks against London, attended by Franco and his staff, who considered that the new weapon would at least prolong the war and facilitate a compromise peace.
