The Secret War: Spies, Codes and Guerrillas 1939–1945. Max Hastings

is gained not by the side that makes no mistakes, but by the one that makes fewer than the other side. By such a reckoning, the ultimate triumph of the British and Americans was as great in the secret war as it became in the collision between armies, navies and air forces. The defining reality is that the Allies won.

      Finally, while some episodes described below seem comic or ridiculous, and reflect human frailties and follies, we must never forget that in every aspect of the global conflict, the stakes were life and death. Hundreds of thousands of people of many nationalities risked their lives, and many sacrificed them, often in the loneliness of dawn before a firing squad, to gather intelligence or pursue guerrilla operations. No twenty-first-century perspective on the personalities and events, successes and failures of those days should diminish our respect, even reverence, for the memory of those who paid the price for waging secret war.

* Agents’ codenames in the pages that follow are given within quotation marks.

* Britain’s MI6 is often known by its other name, SIS – the Secret Intelligence Service – but for clarity it is given the former name throughout this work, even in documents quoted, partly to avoid confusion with the US Signals Intelligence Service.

* The Soviet intelligence service and its subordinate domestic and foreign branches were repeatedly reorganised and renamed between 1934 and 1954, when it became the KGB. Throughout this text ‘NKVD’ is used, while acknowledging also from 1943 the counter-intelligence organisation SMERSh – Smert Shpionam – and the parallel existence from 1926 of the Red Army’s military intelligence branch, the Fourth Department or GRU, fierce rival of the NKVD at home and abroad.

* Americans referred to their Japanese diplomatic decrypt material as ‘Magic’, but throughout this text for simplicity I have used ‘Ultra’, which became generally accepted on both sides of the Atlantic as the generic term for products of decryption of enemy high-grade codes and ciphers, although oddly enough the word was scarcely used inside Bletchley Park.

* ‘Humint’ is the trade term for intelligence gathered by spies, ‘sigint’ for the product of wireless interception.

      1 SEEKERS AFTER TRUTH

      The secret war started long before the shooting one did. One day in March 1937, a letter dropped onto the desk of Colonel František Moravec, addressed to ‘the chief of the Czechoslovak Intelligence Service’ – which was himself. It began: ‘I offer you my services. First of all I shall state what my possibilities are: 1. The build-up of the German army. (a) the infantry …’ and so on for three closely-typed pages. The Czechs, knowing themselves to be prospective prey of Hitler, conducted espionage with an intensity still absent elsewhere among Europe’s democracies. They initially responded to this approach with scepticism, assuming a Nazi ruse, of which there had been plenty. Eventually, however, Moravec decided to risk a response. After protracted correspondence, the letter-writer whom Prague designated as agent A-54 agreed a rendezvous in the Sudeten town of Kraslice. This was almost wrecked by a gunshot: one of Moravec’s aides was so nervous that he fired the revolver in his pocket, putting a bullet through the colonel’s trouser leg. Tranquillity was fortunately restored before the German visitor arrived, to be hurried to a nearby safe house. He brought with him sheaves of secret documents, which he had blithely carted through the frontier posts in a suitcase. Among the material was a copy of Czechoslovakia’s defence plan which revealed to Moravec a traitor in his own ranks, subsequently hanged. A-54 departed from Kraslice still nameless, but richer by 100,000 Reichsmarks. He promised to call again, and indeed provided high-grade information for the ensuing three years. Only much later was he identified as Paul Thummel, a thirty-four-year-old officer of the Abwehr intelligence service.

      Such an episode was almost everyday fare for Moravec. He was a passionate, fiercely energetic figure of middling height. A keen game-player, especially of chess, he spoke six languages fluently, and could read some Latin and Greek. In 1914 he was an eighteen-year-old student at Prague University, with aspirations to become a philosopher. Conscripted into the Austro-Hungarian army, like most Czechs he was unwilling to die for the Hapsburgs, and once at the front seized the first opportunity to desert to the Russians. He was wounded under their flag in Bulgaria, and finished the war with a Czech volunteer force on the Italian front. When Czechoslovakia became an independent state he gratefully cast off these tangled loyalties, to become an officer in its new army. He joined the intelligence branch in 1934, and took over as its chief three years later. Moravec learned the trade mostly from spy stories bought off bookstalls, and soon discovered that many real-life intelligence officers traffic in fiction: his predecessor’s supposed informants proved to have been figments of the man’s imagination, a cloak for embezzlement.

      The colonel devoted much of his service’s resources to talent-spotting in Germany for informants, each network painstakingly ring-fenced. He set up a payday loan company inside the Reich, targeted at military and civil service clients. Within a year ninety of the bank’s representatives were roaming Germany, most bona fide employees, but some of them intelligence personnel who identified borrowers with access to information, vulnerable to bribery or blackmail. The Czechs also pioneered new technology – microdot photography, ultra-violet rays, secret writing and state-of-the-art wirelesses. Moravec was plentifully funded, a recognition of his role in his nation’s front line, and was thus able to pay a Luftwaffe major named Salm 5,000 Reichsmarks – about £500 – as a retainer, and afterwards the huge sum of a million Czech crowns – £7,500 – for Göring’s air force order of battle. Salm, however, flaunted his new-found wealth, and found himself arrested, tried and beheaded. Meanwhile other people’s spies were not idle in Czechoslovakia: Prague’s security officers arrested 2,900 suspects in 1936 alone, most of them allegedly acting for Germany or Hungary.

      Every major nation probed the secrets of others in the same fashion, using both overt and covert means. After Russia’s Marshal Tukhachevksy visited Britain in April 1934, he conveyed personally to Stalin a GRU agent’s description of the RAF’s new Handley Page Hampden bomber, detailing its Bristol and Rolls-Royce engine variants and attaching a sketch showing its armament:

      The Abwehr somehow laid hands on the 1935 fixture list of an ICI plant’s football team, which in the course of the season played at most of the company’s other British factories; Berlin thus triumphantly pinpointed several chemical installations the Luftwaffe had hitherto been unaware of. The Australian aviator Sidney Cotton conducted some pioneering aerial photography over Germany at the behest of MI6’s Wing-Commander Fred Winterbotham. The summer roads of Europe teemed with young couples on touring holidays, some of whom were funded by their respective intelligence services, and displayed an unromantic interest in airfields. MI6 sent an RAF officer, designated as Agent 479, together with a secretary to assist his cover, on a three-week spin around Germany, somewhat hampered by the facts that Luftwaffe station perimeters seldom adjoined autobahns, and neither visitor spoke German. The airman had originally planned to take his sister, who was fluent, but her husband refused consent.

      In the Nazis’ interests, in August 1935 Dr Hermann Görtz spent some weeks touring Suffolk and Kent on a Zündapp motorbike, pinpointing RAF bases with pretty young Marianne Emig riding in his sidecar. But Emig tired of the assignment, or lost her nerve, and Görtz, a forty-five-year-old lawyer from Lübeck who had learned English from
