operations. As the plane passed over the mountains where lay Czechoslovakia’s frontier, the colonel buried his head in his hands and sobbed unashamedly at the prospect of exile. After a brief stop in Amsterdam, the party landed safely at Croydon. When former Czech prime minister Edvard Beneš later arrived in London, Moravec reported to his Putney residence to offer his services and those of his officers, which were readily accepted – his role was formalised the following year, when Beneš formed a government in exile. The colonel’s wife and children escaped from Prague and walked to safety in Poland, from whence they joined him in Britain.
In June 1939 Moravec was delighted to receive a letter, forwarded from a Zürich cover address, which began, ‘Dear Uncle, I think I am in love. I have met a girl.’ On the same page was a secret ink message, appointing a rendezvous in The Hague. It was from agent A-54, the Abwehr colonel Paul Thummel. The Czech officer who duly met him early in August warned Thummel that Moravec’s shrunken organisation no longer had cash to lavish upon him as generously as in the past, but the German responded dismissively that ‘more important matters than money are at stake’. He told the Czech that an invasion of Poland was planned for 1 September, and provided details of the latest Wehrmacht order of battle. He also handed over a list of Polish traitors working for the Germans. Thummel subsequently provided the Nazis’ amended timetable, including on 27 August a final date for the Polish invasion of 3 September 1939. For the people of Czechoslovakia, Poland, and now of all Western Europe, the sparring was over: the death struggle had begun.

1 THE ‘FICTION FLOOD’
The first significant excitement of the British secret service’s war came in November 1939. A document later known as the ‘Oslo Report’ was sent anonymously to the British legation in Norway, then forwarded to London by its naval attaché. The parcel that reached Broadway contained several pages of German typescript and a small cardboard box. It represented the outcome of an earlier ‘feeler’ message to the legation, saying that if the British wanted to receive details of new scientific developments in Germany, they should make a minor change in the wording of a BBC broadcast to Germany: instead of starting, ‘Hello, this is London calling’, it was to say, ‘Hello, hello, this is …’ This was duly done, and after a short delay the ‘Oslo Report’ was submitted.
Its narrative covered a remarkable range of enemy activities. The anonymous author asserted that the Germans were developing acoustic and radio-controlled torpedoes; detailed the wavelengths on which German radar stations were operating; suggested bombing the Luftwaffe research station at Rechlin; and much else. The box contained a trigger tube, to be employed for new anti-aircraft shell proximity fuses. But the credibility of the whole document was undermined by the inclusion of two nonsenses: a claim that the Luftwaffe’s Ju-88 bombers were being produced at the impossible rate of 5,000 a month; and that a German aircraft-carrier, the Franken, was approaching completion at Kiel. These mistakes contributed to a verdict by Whitehall that the document should be dismissed as a German plant.
But the report was also read by Dr Reginald Jones, the outspoken, combative, twenty-eight-year-old assistant director of Air Ministry scientific intelligence. Jones shines forth as an authentic star in the wartime secret firmament. He was a social hybrid, son of a sergeant in the Grenadier Guards who displayed precocious brilliance at his south London school, and later proved as much at ease holding forth at grand country-house parties as fighting his corner in meetings chaired by the prime minister. Having had a notable early career in physics and astronomy at Oxford, where for a time he worked under Frederick Lindemann – later Lord Cherwell – he became fascinated by the possibilities of exploiting infra-red technology for the detection of aircraft, and in 1936 went to work for the Air Ministry. He was intolerant of slow-mindedness or bureaucracy wherever he encountered it, and there was plenty of both at Broadway Buildings, where after a brief stint at Bletchley Park he was invited to share an office with Fred Winterbotham.
In the course of the war Reg Jones became one of the foremost British investigators of German air technology. In November 1939, however, his achievements still lay in the future, and he was seen in Whitehall simply as a pushy young ‘boffin’ who seemed too free with his opinions in the presence of senior officers. Jones, almost alone, elected to believe that the Oslo document was authentic. His instinct became a near-certainty in the summer of 1940, when the Luftwaffe began to use the Wotan navigational beam to guide its bombers over Britain, exploiting principles mentioned by Oslo’s author. R.V. Jones, as he is known to posterity, found the information invaluable in devising counter-measures during the ‘Battle of the Beams’ that influenced the Blitz – which gained him the ear and the admiration of Winston Churchill. Again and again through the years that followed, when the British gained hints about new German weapons – the acoustic torpedo, for example – Jones was able to point out to service chiefs that Oslo had warned of them. After the war, in a retrospective on his own intelligence career, the scientist used the example of the 1939 document to urge that ‘casual sources should not be treated flippantly. It was probably the best single [scientific intelligence] report received from any source during the war.’
Only after an interval of almost forty years did Jones establish the document’s authorship. It was the work of a forty-five-year-old German physicist named Hans Ferdinand Mayer, who adopted a scientific career after being badly wounded on his first day in action as a conscript in 1914. He had been employed by Siemens since 1922, doing work that resulted in the award of eighty-two patents and the publication of forty-seven papers, and also spent four years as professor of signals technique at America’s Cornell University. During the inter-war years he formed a warm friendship with an Englishman working for GEC named Cobden Turner, who became godfather to Mayer’s second son. The German was especially impressed by a good deed: when he told Turner about the tragic case of a Jewish schoolchild disowned by her Nazi father, the Englishman arranged for the little girl to come to England, where for eight years she lived as a member of his own family.
When the international horizon darkened, on what proved Turner’s final visit to Germany Mayer told him that if war came, he would try to supply Britain with information about German scientific and technological progress. In late 1939 the scientist exploited a chance business trip to Norway to make good on his promise. He borrowed an old typewriter from the porter at the Hotel Bristol and composed the ‘Oslo Report’, which was dispatched in two parts to the British embassy on 1 and 2 November. Mayer also wrote directly to Cobden Turner, suggesting further contact through an intermediary in neutral Denmark. But although this letter caused two British security officers to visit and question the GEC man, for reasons unknown nothing was done to open communication with Mayer – MI6’s official history makes no mention of this courageous German. In August 1943 Mayer was arrested by the Gestapo in his office at Siemens, and charged with listening to the BBC. He was confined in Dachau, but was fortunate enough to be employed in a technical plant, where he survived the war. His brave gesture was prompted by admiration for Cobden Turner, whom he liked to regard as a representative Englishman. Recognition of Mayer’s contribution, however, came only from Reg Jones.
Among the reasons the ‘Oslo Report’ received such a chilly reception is that it was debated in Whitehall just as the British secret community reeled in the wake of a successful German ruse. On 9 November 1939, during the first, passive phase of the war that became derisively known as the ‘sitzkrieg’,
