On July 25, 1944 the New York residency telegraphed the Centre: “Almost half a year of contact established with REST [Fuchs] has demonstrated the value of his work for us.” It asked permission to pay him a “reward” of 500 dollars. The Centre agreed, but, before the money could be handed over, Fuchs had disappeared.41 It was over three months before Gold discovered that Fuchs had been posted to Los Alamos, and he did not renew contact with him until Fuchs returned to the east coast on leave in February 1945.42
During 1944 Kvasnikov’s responsibilities were extended: he was given the new post of ST resident for the whole of the United States—a certain indication of the increasing priority of atomic espionage.43 Late in 1944 Kvasnikov was able to inform the Centre that, in addition to Fuchs, there were now two more prospective spies at Los Alamos.
The first, David Greenglass, was recruited through a group of ST agents run by Julius Rosenberg (codenamed successively ANTENNA and LIBERAL), a 26-year-old New York Communist with a degree in electrical engineering. Like Fuchs, the members of the Rosenberg ring, who included his wife Ethel, had been rewarded with cash bonuses in the summer. The ring was producing so many classified documents to be photographed in Kvasnikov’s apartment that the New York residency was running dangerously short of film. The residency reported that Rosenberg was receiving so much intelligence from his agents that he was finding it difficult to cope: “We are afraid of putting LIBERAL out of action with overwork.”44
In November 1944 Kvasnikov informed the Centre that Ethel Rosenberg’s sister, Ruth Greenglass (codenamed WASP), had agreed to approach her husband, who worked as a machinist at Los Alamos.45 “I was young, stupid and immature,” said David Greenglass (codenamed BUMBLEBEE and CALIBRE) later, “but I was a good Communist.” Stalin and the Soviet leadership, he believed, were “really geniuses, every one of them:” “More power to the Soviet Union and abundant life for their peoples!” “My darling,” Greenglass wrote to his wife, “I most certainly will be glad to be part of the community project [espionage] that Julius and his friends [the Russians] have in mind.”46
The New York residency also reported in November 1944 that the precociously brilliant nineteen-year-old Harvard physicist Theodore Alvin (“Ted”) Hall, then working at Los Alamos, had indicated his willingness to collaborate. As well as being inspired by the myth-image of the Soviet worker-peasant state, which was an article of faith for most ideological Soviet agents, Hall convinced himself that an American nuclear monopoly would threaten the peace of the post-war world. Passing the secrets of the MANHATTAN project to Moscow was thus a way “to help the world,” as well as the Soviet Union. As the youngest of the atom spies, Hall was given the appropriate, if transparent, codename MLAD (“Young”). Though only one year older, the fellow Harvard student who first brought Hall into contact with the NKGB, Saville Savoy Sax, was codenamed STAR (“Old”).47 Hall himself went on to become probably the youngest major spy of the twentieth century.
THE PENETRATION OF Los Alamos was part of a more general surge in Soviet intelligence collection in the United States during the last two years of the war, as the NKGB’s agents, buoyed up by the remorseless advance of the Red Army towards Berlin and the opening of a second front, looked forward to a glorious victory over fascism. The number of rolls of microfilm sent by Akhmerov’s illegal residency to Moscow via New York grew from 211 in 1943 to 600 in 1944 and 1,896 in 1945.48 The Centre, however, found it difficult to believe that espionage in the United States could really be as straightforward as it seemed. During 1944-5 the NKGB grew increasingly concerned about the security of its American operations and sought to bring them under more direct control.49 Among its chief anxieties was Elizabeth Bentley’s habit of socializing with the agents for whom she acted as courier. When Bentley’s controller and lover, Jacob Golos, died from a sudden heart attack on Thanksgiving Day 1943, Akhmerov decided to dispense with a cut-out and act as her new controller. Bentley’s first impressions were of a smartly dressed “jaunty-looking man in his mid-thirties” with an expansive manner. (Akhmerov was actually fortytwo). She soon realized, however, that “despite the superficial appearance of a boulevardier, he was a tough character.”50 For the next six months, though Bentley continued to act as courier for the Silvermaster group in Washington, she felt herself under increasing pressure.
In March 1944 Earl Browder passed on to her another group of Washington bureaucrats who had been sending him intelligence which he had previously passed on to Golos.51 Bentley regarded Victor Perlo (RAIDER), a government statistician who provided intelligence on aircraft production, as the leader of the group—probably because he acted as spokesman during her first meeting with them.52 Akhmerov, however, believed that the real organizer was Charles Kramer (LOT), a government economist, and was furious that the Perlo/Kramer network had been handed over by Browder not to him but to Bentley. For over a year, he told the Centre, Zarubin and he had wanted to make direct contact with the group, but Browder had failed to arrange it. “If we work with this group,” Akhmerov added, “it will be necessary to remove [Bentley].”53
Bentley appealed to Browder for support as she struggled to remain the courier for the Washington networks. “Night after night, after battling with [Akhmerov],” wrote Bentley later, “I would crawl home to bed, sometimes too weary to undress.” Eventually, Bentley agreed to arrange a meeting between Akhmerov and Silvermaster (PAL). Soon afterwards, according to Bentley, Akhmerov told her, “almost drooling with arrogance:” “Earl [Browder] has agreed to turn Greg [Silvermaster] over to me… Go and ask him.” “Don’t be naive,” Browder told Bentley the next day. “You know that when the cards are down, I have to take my orders from them.”54 Akhmerov reported to the Centre that Bentley had taken her removal from the Silvermaster group “very much to heart… evidently supposing that we do not trust her. She is offended at RULEVOY [Browder] for having consented to our liaison with PAL.”55
Bentley was also removed from contact with the Perlo/Kramer group. Gorsky tried to placate her by inviting her to dinner at a waterfront restaurant in Washington. He made a bad start. “I hope the food is good,” he said. “Americans are such stupid people that even when it comes to a simple matter like cooking a meal, they do it very badly.” “Ah, yes,” he added, seeing Bentley’s expression change. “I had forgotten for the moment that you, too, are an American.” Gorsky went on to tell her that she had been awarded the Order of the Red Star (“one of the highest—reserved for all our best fighters”) and showed her a facsimile: “We all think you’ve done splendidly and have a great future before you.” GOOD GIRL was not to be placated.56 A year later she secretly began telling her story to the FBI.
The Centre was also worried by increased FBI surveillance of the New York Soviet consulate, which housed the legal residency, and by a warning from Duncan Lee (KOCH) in September 1944 that the OSS Security Division was compiling a list of Communists and Communist sympathizers in OSS.57 The Centre’s nervousness was shared by some of its best agents. Bentley found Lee himself “on the verge of cracking up… so hypercautious that he had taken to crawling around the floor of his apartment on hands and knees examining the telephone wires to see if they had been tampered with.”58 Another highly placed Soviet agent, the senior Treasury official Harry Dexter White (JURIST), told his controller that, though he was unconcerned for his own personal security and his wife had prepared herself “for any self-sacrifice,” he would have to be very cautious because of the damage to the “new course” (the Soviet cause) which would occur if he were exposed as a spy. He therefore proposed that in the future they have relatively infrequent meetings, each lasting about half an hour, while driving around in his car.59
There was a further alarm in November which, according to Bentley, followed an urgent warning from an agent in the White House, Roosevelt’s administrative assistant Lauchlin Currie. Currie reported that “the Americans were on the verge of breaking the Soviet code.”60 The alarm appears to have subsided when it was discovered
that Currie had wrongly concluded that a fire-damaged NKGB codebook obtained by OSS from the Finns would enable Soviet communications (which went through a further, theoretically impenetrable, encipherment by “one-time pad”) to be decrypted.61 (Given the phenomenal success of Anglo-American codebreakers in breaking the highest grade German and Japanese ciphers, Currie’s mistake is understandable.) At Roosevelt’s insistence, Donovan returned the NKGB codebook to the Soviet embassy. A doubtless bemused Fitin sent Donovan his “sincere thanks.”62
DESPITE ALL THE Centre’s anxiety that Soviet espionage was about to be exposed, and despite all the confusion in the residencies, the NKGB’s eager American and British agents continued to provide intelligence remarkable for both its quantity and quality. The NKGB proudly calculated after the war that the grand total of its wartime agents and informers (“confidential contacts”) around the world had been 1,240, who had provided 41,718 items of intelligence. Approximately 3,000 foreign intelligence reports and documents had been judged important enough to be sent to the State Defense Committee and the Central Committee. Eighty-seven foreign intelligence officers were decorated for their wartime work.63
Moscow made far better use of ST than of its political intelligence, which was always likely to be ignored or regarded with suspicion when it disagreed with Stalin’s conspiracy theories—or with those of the Centre, which were closely modeled on his. ST from the West, by contrast, was welcomed with open and unsuspicious arms by Soviet scientists and technologists. A. F. Ioffe, the director of the USSR Academy of Sciences Leningrad Physics and Technological Institute, wrote of wartime ST:
The information always turns out to be accurate and for the most part very complete… I have not encountered a single false finding. Verification of all the formulae and experiments invariably confirms the data contained in the materials.64
The most valuable ST concerned the atomic program. Kurchatov reported to Beria on September 29, 1944 that intelligence revealed the creation for the MANHATTAN project of “a concentration of scientific and engineering-technical power on a scale never before seen in the history of world science, which has already achieved the most priceless results.”65 According to NKGB calculations, up to November 1944 it had acquired 1,167 documents on nuclear research, of which 88 from the United States and 79 from Britain were judged of particular importance.66 The most important, however, were yet to come.
On February 28, 1945 the NKGB submitted to Beria its first comprehensive report on atomic intelligence for two years—also the first to be based on reports from inside Los Alamos. Five months before the successful test of the first atomic bomb at Alamogordo in southern New Mexico, the Centre was informed of all the main elements in its construction. The information which Fuchs had passed to Gold on the east coast in mid-February arrived too late to be included in the Centre’s assessment. The report passed to Beria was, almost certainly, based chiefly on intelligence from the nineteen-year-old Theodore Hall and technical sergeant David Greenglass. There can be little doubt that Hall’s intelligence, delivered to the New York residency by his friend, Saville Sax, was the more important. It was probably Hall who first revealed the implosion method of detonating the bomb, though a more detailed report on implosion by Fuchs reached Kurchatov on April 6.67
In the spring of 1945 Sax was replaced as courier between Hall and the New York residency by Leontina (“Lona”) Cohen, codenamed LESLIE. “Lona” had been recruited in 1941 by her husband Morris (codenamed LUIS), who had become a Soviet agent during the Spanish Civil War while serving in the International Brigades. The couple, later to figure among the heroes of Soviet intelligence, were collectively codenamed the DACHNIKI (“Vacationers”), but their careers as agents were interrupted by Morris’s conscription in 1942. “Lona” was reactivated early in 1945 to act as a courier to both Los Alamos and the Anglo-Canadian atomic research center at Chalk River, near Ottawa, which was also penetrated by Soviet agents. While she made contact with Hall, Gold acted as courier for Fuchs and Greenglass. Each of the three Soviet agents was completely ignorant of the espionage conducted by the other two.68
It is probable that both Fuchs and Hall independently furnished the plans of the first atomic bomb, each of which the Centre was able to crosscheck against the other.69 Fuchs and Hall also independently reported that the test of the first atomic bomb had been fixed for July 10, 1945,70 though in the end weather conditions caused it to be postponed for six days. A month later the Pacific War was at an end. Following the bombing of Hiroshima and Nagasaki on August 6 and 9, Japan surrendered.
Lona Cohen spent the final dramatic weeks of the Pacific War in New Mexico, waiting for Hall to deliver the results of the Alamogordo test. After missing rendezvous in Albuquerque on three consecutive Sundays, Hall finally handed a set of highly classified papers to his courier, probably soon after the Japanese surrender.71 On catching the train back to New York, Lona Cohen was horrified to see military police on board searching passengers’ luggage. With remarkable presence of mind she thrust Hall’s documents inside a newspaper and gave it to a policeman to hold while she opened her purse and suitcase for inspection. The policeman handed the newspaper back, inspected her purse and suitcase, and Mrs. Cohen returned safely to New York.72
Thanks chiefly to Hall and Fuchs, the first Soviet atomic bomb, successfully tested just over four years later, was to be an exact copy of the Alamogordo bomb. At the time, however, the Centre found it difficult to believe that the theft of two copies of perhaps the most important secret plans in American history could possibly escape detection. The sheer scale of its success made the NKGB fear that the penetration of the MANHATTAN project would soon be uncovered by the Americans.
The NKGB officer in charge of intelligence collected from Los Alamos in 1945 was Anatoli Antonovich Yatskov (alias “Yakovlev,” codenamed ALEKSEI), an engineer recruited by the NKVD in 1939 who succeeded Kvasnikov as ST resident in the United States.73 He is nowadays remembered as one of the heroes of Russian foreign intelligence.74 At the time, however, the Centre was bitterly critical of him. In July 1945 it concluded that his carelessness had probably compromised MLAD, and denounced his “completely unsatisfactory work with the agents on ENORMOZ [the MANHATTAN project].”75 At the very moment of Soviet intelligence’s greatest ever triumph in the United States, the acquisition of the plans of the first atomic bomb, the Centre wrongly feared that the whole ENORMOZ operation was in jeopardy.
The GRU, as well as the NKGB, had some striking successes in the wartime United States. Though Soviet military intelligence had been forced to surrender both Fuchs and the majority of its more important pre-war American agents to the more powerful NKGB, it had succeeded in retaining at least one of whom the Centre was envious in 1945. Gorsky reported to the Centre a conversation between Akhmerov and ALES (Alger Hiss), who had been working for the GRU for the past ten years.76 Though Hiss was a senior diplomat, Akhmerov said that the GRU had generally appeared little interested in State Department documents, and had asked Hiss and a small group of agents, “for the most part consisting of his relations,” to concentrate on military intelligence.77 Late in 1944, however, Hiss’s role as a Soviet agent took on a new significance when he became actively engaged in preparations for the final meeting of the wartime Big Three at Yalta in the Crimea in February 1945.
Yalta was to prove an even bigger success for Soviet intelligence than Tehran. This time both the British and the American delegations, housed respectively in the ornate Vorontsov and Livadia Palaces, were successfully bugged. The mostly female personnel used to record and transcribe their private conversations were selected and transported to the Crimea in great secrecy. Not till they arrived at Yalta did they discover the jobs that had been assigned to them.78 The NKGB sought, with some success, to distract both delegations from its surveillance of them by lavish and attentive hospitality, personally supervised by a massive NKGB general, Sergei Nikiforovich Kruglov. When Churchill’s daughter, Sarah, casually mentioned that lemon wen
t well with caviar, a lemon tree appeared, as if by magic, in the Vorontsov orangery. At the next Allied conference, in Potsdam, General Kruglov was rewarded with a KBE, thus becoming the only Soviet intelligence officer to receive an honorary knighthood.
Stalin was even better informed about his allies at Yalta than he had been at Tehran. All of the Cambridge Five, no longer suspected of being double agents, provided a regular flow of classified intelligence or Foreign Office documents in the runup to the conference, though it is not possible to identify which of these documents were communicated to Stalin personally. Alger Hiss actually succeeded in becoming a member of the American delegation. The problem which occupied most of the time at Yalta was the future of Poland. Having already conceded Soviet dominance of Poland at Tehran, Roosevelt and Churchill made a belated attempt to secure the restoration of Polish parliamentary democracy and a guarantee of free elections. Both were outnegotiated by Stalin, assisted once again by a detailed knowledge of the cards in their hands. He knew, for example, what importance his allies attached to allowing some “democratic” politicians into the puppet Polish provisional government already established by the Russians. On this point, after initial resistance, Stalin graciously conceded, knowing that the “democrats” could subsequently be excluded. After first playing for time, Stalin gave way on other secondary issues, having first underlined their importance, in order to preserve his allies’ consent to the reality of a Soviet-dominated Poland. Watching Stalin in action at Yalta, the permanent under-secretary at the Foreign Office, Sir Alexander Cadogan, thought him in a different league as a negotiator to Churchill and Roosevelt: “He is a great man, and shows up very impressively against the background of the other two aging statesmen.” Roosevelt, in rapidly failing health and with only two months to live, struck Cadogan, by contrast, as “very woolly and wobbly.”79
