Description

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 Southern Europe: a report of German naval operations in the Adriatic, covering February 9-12; Naval Headlines, which includes 9 items from U-boat communications; and that the Germans continued their anti-invasion exercise on February 11 in the Bay of Biscay with a notional Allied landing on Ile d'Yeu; from the Ministry of Foreign Affairs in Berlin, a repeat transmission to all German embassies of a secret report from the German ambassador in Paris dated February 3 on an Allied summit meeting in Tehran; on disagreement between the Allies on when to start a second front in Western Europe; and also describing some uncertainty between the Algiers Committee and London and between Churchill and De Gaulle when they met in Marrakesh; from the Portuguese minister in Budapest, on the internal situation in Hungary, on February 8, noting fear of a Russian invasion and being abandoned by the Germans; and that rumours of the evacuation of civilians from Budapest were unfounded; from the Ministry of Foreign Affairs in Berlin, a repeat transmission to all German embassies of a report from the German ambassador in Madrid on February 6, including detailed observations made during the ambassador's visits to Valencia and Barcelona and on his return to Madrid; and detailing Allied pressure on Spain for true neutrality and Spanish moves to placate the Allies following their successes in North Africa and the Mediterranean area, with the Allies being intent on forcing Spain to sever relations with Germany as happened in Argentina; and from the Portuguese minister in Tokyo, on the internal situation in Japan which he described as disastrous with shortages of food, transport and aviation; on government calls for national unity in this 'the year of victory', on February 7; and that the Allied invasion of the Marshall Islands and U.S. air attacks against the islands of New Guinea had badly dented Japanese national pride.
