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 by a gentleman’.
British intelligence had enjoyed a good Great War. The Royal Navy’s codebreakers, such men as Dillwyn Knox and Alastair Denniston, labouring in the Admiralty’s Room 40, provided commanders with a wealth of information about the motions of the German High Seas Fleet. The decryption and public revelation of Berlin’s 1917 Zimmermann Telegram, urging the Mexicans to take aggressive action against the United States, played a critical role in bringing the Americans into the war. For two years after the November 1918 Armistice, the secret service was deeply involved in the Allies’ unsuccessful attempt to reverse the outcome of the Russian Revolution. Even after this was abandoned, the threat from international communism remained the foremost preoccupation of British espionage and counter-espionage.
Yet amid the inter-war slump, funding was squeezed. MI6 mouldered, to an extent little understood by either Britain’s friends or foes. Hugh Trevor-Roper, the historian who became one of its wartime officers, wrote: ‘Foreign intelligence services envied the British secret service; it was their idealised model … It enjoyed the reputation of an invisible, implacable force, like the Platonic world-spirit, operating everywhere. To the Nazi government, it was at the same time a bogey and an ideal … The reality … was rather different.’ MI6’s senior officers were men of moderate abilities, drawn into the organisation by the lure of playing out a pastiche of Kipling’s ‘Great Game’, and often after earlier careers as colonial policemen.
They masqueraded as passport control officers in embassies abroad, or shuffled paper in the service’s austere – indeed, frankly squalid – headquarters beside St James’s Park underground station, in Broadway Buildings, a place of threadbare carpets and unshaded lightbulbs. MI6 sustained a quirky tradition of paying its staff tax-free and in cash, but so small a pittance that a private income was almost essential for officers who aspired to an upper-middle-class lifestyle, which meant all of them. Though its budget was progressively increased from £180,000 in 1935 to £500,000 in 1939, few graduates entered the service, because its bosses did not want them. MI6, in the view of one practitioner, was designed merely to receive intelligence rather than actively to procure it. It was run by a coterie of anti-intellectual officers who saw their principal, if not sole, task as that of combating revolutionary communism. The shift of emphasis to monitoring Nazis and fascists during the late pre-war period caused great difficulties.
Some recruits of that period proved ill-suited to the essential nastiness of espionage. Lt. Cmdr Joseph Newill, a retired sailor posted to Scandinavia in 1938 on the strength of speaking Norwegian, wailed to London: ‘I doubt whether I have the natural guile so essential for this work!’ Newill complained that his role involved much more hard labour than he had expected. He told his station chief petulantly: ‘I am 52 and I am not going to work myself to death at my time of life.’ But he was kept in the job, and contrived to meet Broadway’s undemanding standards. MI6’s Shanghai station chief, Harry Steptoe, operated under cover as vice-consul. A jaunty little cock-sparrow figure who affected a moustache and monocle, he puzzled a foreign diplomat by his appearance at receptions in a lovat-green suit adorned with gold braid. Was this, demanded the diplomat, the full-dress uniform of the British secret service? When the Japanese interned Steptoe in 1942, they dismissed
