СКАЧАТЬ Captain John King, was found to have been funding an American mistress by peddling secrets. In 1937 a local employee in Britain’s Rome embassy, Francesco Constantini, was able to rifle his employer’s papers for the benefit of the Italian secret service, because the ambassador assumed that one could trust one’s servants. At that period also, Mussolini’s men read some British codes: not all Italians were the buffoons their enemies supposed. In 1939, when Japanese intelligence wanted the codebooks of the British consulate in Taipei, its officers easily arranged for a Japanese employee to become night-duty man. During the ensuing six months Tokyo’s agents repeatedly accessed the consulate safe, its files and codebooks.

      Yet nowhere in the world was intelligence wisely managed and assessed. Though technological secrets were always useful to rival nations, it is unlikely that much of the fevered secret political and military surveillance told governments more than they might have gleaned from a careful reading of the press. Endemic rivalries injured or crippled collaboration between intelligence agencies. In Germany and Russia, Hitler and Stalin diffused power among their secret policemen, the better to concentrate mastery in their own hands. Germany’s main agency was the Abwehr, its title literally meaning ‘security’, though it was responsible for both intelligence-gathering abroad and counter-espionage at home. A branch of the armed forces, it was directed by Admiral Wilhelm Canaris. When Guy Liddell, counter-espionage director of MI5 and one of its ablest officers, later strove to explain the Abwehr’s incompetence, he expressed a sincere belief that Canaris was in the pay of the Russians.

      The Nazis also had their own security machine, the Reichssicherheitshauptamt or RSHA, directed by Ernst Kaltenbrunner within the empire of Himmler. This embraced the Gestapo secret police and its sister counter-intelligence branch the Sicherheitdienst or SD, which overlapped the Abwehr’s activities in many areas. A key figure was Walter Schellenberg, Reinhard Heydrich’s aide: Schellenberg later took over the RSHA’s foreign intelligence-gathering service, which subsumed the Abwehr in 1944. High Command and diplomatic codebreaking activities were conducted by the Chiffrierabteilung, colloquially known as OKW/Chi, and the army had a large radio intelligence branch that eventually became OKH/GdNA. Göring’s Air Ministry had its own cryptographic operation, as did the Kriegsmarine. Economic intelligence was collected by the WiRuAmt, and Ribbentrop’s Foreign Ministry gathered reports from embassies abroad. Guy Liddell wrote crossly: ‘Under our system of government there was nothing to stop the Germans from getting any information they required.’ But the elaborate Nazi intelligence and counter-espionage machines were far more effective in suppressing domestic opposition than in exploiting foreign sources, even when they heard something useful from them.

      France’s intelligence departments enjoyed a lowly status and correspondingly meagre budgets. Pessimism overlaid upon ignorance caused them consistently to overstate German military strength by at least 20 per cent. František Moravec believed that politics crippled French security policy as war loomed: ‘Their desire to “know” seemed to decrease proportionately as the Nazi danger increased.’ Moravec the Czech found his French counterparts half-hearted colleagues, though he returned from one inter-Allied conference with a present from a famous French criminologist, Professor Locarde of Lyons: a chemical developer which proved useful for exposing secret writing.

      Since the beginning of time, governments had been able to intercept each other’s communications only when spies or accidents of war physically diverted messages into their hands. Now, however, everything was different. Wireless communication was a science slightly older than the twentieth century, but thirty years elapsed before it became a universal phenomenon. Then, during the 1930s, technological breakthroughs prompted a global explosion of transmissions. The ether hummed, whined and crackled as messages private, commercial, military, naval, diplomatic traversed nations and oceans. It became indispensable for governments and their generals and admirals to communicate operational orders and information by radio, to every subordinate, ship and formation beyond reach of a landline. Making such exchanges secure demanded nice judgements. There was a trade-off between the speed at which a signal could be dispatched and received, and the subtlety of its encryption. It was impracticable to provide front-line army units with ciphering machines, and thus instead they employed so-called hand- or field-ciphers, of varying sophistication – the German army used a British-derived system called Double Playfair.

      For the most secret messages, the only almost unbreakable code was that based upon a ‘one-time pad’, a name that reflected its designation: the sender employed a unique combination of letters and/or numbers which became intelligible only to a recipient pre-supplied with the identical formula. The Soviets especially favoured this method, though their clerks sometimes compromised it by using a one-time pad more than once, as the Germans found to their advantage. From the 1920s onwards, some of the major nations started to employ ciphers which were deemed impregnable if correctly used, because messages were processed through electrically-powered keyboard machines which scrambled them into multi-millions of combinations. The magnitude of the technological challenge posed by an enemy’s machine-encrypted signals did not deter any nation from striving to read them. This became the most important intelligence objective of the Second World War.

      The brightest star of the Deuxième Bureau, France’s intelligence service, was Capitaine Gustave Bertrand, head of the cryptanalytical branch in the army’s Section des Examens, who had risen from the ranks to occupy a post that no ambitious career officer wanted. One of his contacts was a Paris businessman named Rodolphe Lemoine, born Rudolf Stallman, son of a rich Berlin jeweller. In 1918 Stallman adopted French nationality; simply because he loved espionage as a game in its own right, he began to work for the Deuxième. In October 1931 he forwarded to Paris an offer from one Hans-Thilo Schmidt, brother of a German general, to sell France information about Enigma in order to dig himself out of a financial hole. Bertrand accepted, and in return for cash Schmidt delivered copious material about the machine, together with its key settings for October and November 1932. Thereafter he remained on the French payroll until 1938. Since the French knew that the Poles were also seeking to crack Enigma, the two nations agreed a collaboration: Polish cryptanalysts focused on the technology, while their French counterparts addressed enciphered texts. Bertrand also approached the British, but at the outset they showed no interest.

      Britain’s codebreakers had acquired an early-model commercial Enigma as early as 1927, and examined it with respect. Since then, they knew that it had been rendered much more sophisticated by the inclusion of a complex wiring pattern known as a Steckerbrett, or plugboard. It now offered a range of possible positions for a single letter of 159 million million million. That which human ingenuity had devised, it was at least theoretically possible that human ingenuity might penetrate. In 1939, however, no one for a moment imagined that six years later intelligence snatched from the airwaves would have proved more precious to the victors, more disastrous for the losers, than every report made by all the spies of the warring nations.

2 THE BRITISH: GENTLEMEN AND PLAYERS

      The reputation of MI6 was unmatched by that of any other secret service. Though Hitler, Stalin, Mussolini and Japan’s generals shared a scepticism, or even scorn, about the old lion’s fitness to fight, they viewed its spies with extravagant respect, indeed cherished a belief in their omniscience. British prowess in clandestine activity dated back to the sixteenth century at least. Francis Bacon wrote in his History of the Reign of King Henry VII: ‘As for his secret Spials, which he did employ both at home and abroad, by them to discover what Practises and Conspiracies were against him, surely his Case required it.’ Queen Elizabeth I’s Sir Francis Walsingham was one of history’s legendary spymasters. Much later came the romances of Rudyard Kipling’s Kim, of John Buchan’s Richard Hannay, of dashing ‘clubland heroes’ who played chess for England with a thousand live pieces across a board that spanned continents. A wartime British secret servant observed: ‘Practically every officer I met in that concern, at home and abroad, was, like me, imagining himself as Hannay.’ The great Danish physicist Niels Bohr told the scientific intelligence officer R.V. Jones that he was happy to cooperate with the British secret service because ‘it was run СКАЧАТЬ
