Introduction
The Cold War was more than a geopolitical standoff—it was a chessboard of intrigue, espionage, and deception played out in the shadows of history.
Beneath the polished diplomacy and public propaganda, a hidden war unfolded, where spies swapped secrets, counterintelligence redefined betrayal, and nations danced on the razor's edge of nuclear annihilation.
This era birthed legends of intelligence and treachery, from covert operations like Operation Paperclip to the infamous Cambridge Five.
It was a time when a simple penny could hold state secrets and double agents infiltrated the highest echelons of power.
How did two global superpowers weaponize intelligence to wage a war without bombs?
And how did the lives of ordinary individuals, from unsuspecting civilians to defecting spies, shape the clandestine battle for supremacy?
Let’s uncover the covert operations, betrayals, and audacious strategies that defined the shadowy heart of the Cold War.
The Beginning
At the start of World War II, the United States was well behind in intelligence matters.
Although espionage had existed since the Civil War, there was no central coordinating agency.
There were around a dozen federal agencies that competed rather than cooperated.
England, like the Soviet bloc, did not have this difficulty.
Since Dzerzhinsky established the Cheka in 1917, the USSR's spy service has continued to expand under many names (GPU, OGPU, NKVD, NKGB, MGB, and, since 1954, the KGB).
Its primary responsibilities were tracking down dissidents, real or imaginary, to prevent any effort at subversion and to supply victims of Stalin's purges, but it did not ignore foreign action.
A primary goal was to penetrate British intelligence and develop a network of double agents at its centre.
As Roosevelt's personal envoy, American General William J. Donovan travelled to England in 1940 to gain insight into MI-6 operations.
They talked about the primary roles of the British intelligence service as well as the Ultra-Sector Enigma project. To establish a consolidated institution whose director would answer directly to the president, the general returned to the United States.
Donovan directed the establishment of the Office of the Coordinator of Information (IOC) in 1941. In 1942, following the United States' entry into the war and with the participation of military personnel, it changed its name to the Office of Strategic Affairs, or OSS, as it was more commonly known in English.
According to Donovan, the organisation of an espionage agency needed to be more than just a military or governmental entity.
Thus, he employed experts in every industry as long-term workers or partners, including:
- historians
- economists
- scientists
- bankers
- university rectors
- sports
- actors
- filmmakers
When the OSS peaked in 1944, it employed 13,000 people, 4,500 of them were women.
When the war ended in September 1945, however, the government abolished it.
After Donovan pushed for it to become a civilian organisation that would function during times of peace, President Truman signed the National Security Act of 1947, establishing the Central Intelligence Agency (CIA).
The National Security Council convened for the first time in Washington in December of that year, and they decided to deploy the new organisation to carry out secret operations throughout Europe.
Considering the new global circumstances, the United States was aware that it would require an organisation to manage activities that would upset the public if they were made public.
Of course, defending against hostile forces was a top priority.
Leading the race to save the usable remnants of vanquished Germany, however, was an even greater priority.
Operation "Paperclip"
Reinhard Gehlen, the Nazi commander of counterintelligence on the Eastern Front, agreed to give the United States access to all of his soldiers and assets when CIA officer Frank Wiesner started a series of talks with him near the conclusion of the war.
This served as the model for Operation Paperclip, which aimed to enlist as many Germans as possible.
The Nazi army concluded in 1943 that removing researchers from the battlefield and assigning them to laboratories would be more beneficial.
The phrase "German scientists" was obviously merely a euphemism.
From the most well-known, Wernher von Braun, to Kurt H. Debus, a former member of the SS who would go on to become the director of the Cape Canaveral Launch Centre, many of them were Nazis.
While other professionals attended, rocket specialists were most sought after because they were crucial to the space race and rocket construction.
The Soviet Union had similar plans.
The Race Against the Russians
But the Russians were already working on Operation “Osoavia” in 1946, which was intended to serve the same function as the "Paperclip" but used fewer conversational techniques.
They sent Russia 92 trains overnight to work on missile research and production, which had previously been planned for almost 6,000 scientists and their families.
Helmut Grottrup, von Braun's aide, was one of them. He decided to follow the Soviet route to shine his own light and leave his old boss' shadow.
He also had advantages, such as luxurious accommodations and a car with a driver, which were very different from the typical comforts enjoyed by most of his coworkers.
No one needed an explanation from the USSR.
The US transfer of researchers was done discreetly because it is unlikely that the American people would accept that their government was willing to forget its foes' past in exchange for their skill.
The proximity of some of their targets was so near that even the Department of Justice's Office of Special Investigations agents, whose job it was to track down fugitive Nazi criminals, disregarded it for years.
As "special service officers of the war department," some scientists travelled directly from Germany to American military installations with their families.
Others entered through Mexico, where the consulate in Ciudad Juárez awarded them U.S. residence.
Operation "Alsos"
Even more covert than a paperclip, Operation "Alsos" had a similar objective.
Some of the European scientists involved in the Manhattan Project, which produced the first atomic weapon, were worried that Germany had succeeded in creating its own bomb.
"Alsos" attempted to ascertain the extent of the Nazis' research, but he encountered a problem: the American effort was so covert that intelligence services were unable to obtain the information they needed to assess German advancements.
Establishing an espionage division under the direction of the Manhattan Project's engineers was the answer.
The Cambridge Five
In addition to these activities, the primary objective of espionage during those years was the recruitment of double agents in enemy territory, ideally in the highest levels of military or political authority.
Six hundred former Nazis in the Soviet zone of occupied Germany—known as the Gehlen Organization—started spying for the United States when Frank Wiesner and Reinhard Gehlen met. However, the West was unaware at the time of the extent to which the Russians had taken the lead in this area and advanced into the heart of England.
Who would have thought that one of Britain's top colleges would produce traitors willing to surrender to the USSR?
In the 1920s and 1930s, Oxford and Cambridge were major hubs for communist recruiting.
Nevertheless, some of the new party members transitioned from militancy to espionage elsewhere.
Along with other members of the intellectual society Los Apostles, including Donald Maclean, Guy Burgess, Anthony Blunt, and John Cairncross (though the latter's involvement was never entirely verified), Kim Philby had been spying for the Russians for years when the CIA was established in 1947.
The Five persisted in their employment for many years, holding progressively more significant roles and having access to more classified material.
Philby, an MI-6 member, held the position of director of the Anti-Soviet Department and was a strong candidate to head the Secret Service.
Burgess and Maclean defected to the USSR in 1951 after Philby alerted them to their suspicions. He would follow their suit in 1963, not long after he was forced to quit and became a suspect himself.
Blunt was the only one still in England, having made a deal with the British government to provide information in return for immunity.
A coin
On June 22, 1953, fate's whims left a young Brooklyn newspaper deliveryman holding a penny.
Since it appeared to weigh less than the others, he removed it to give it a closer look, dropped it on the ground, and the coin broke in two.
A small snapshot of a string of typed numbers was inside. The FBI eventually obtained the coin and its contents and, despite their inability to decode it, determined that the numbers were some sort of code.
After four years of no improvement, Russian Lieutenant Colonel Reino Häyhänen asked for political asylum at the American Embassy in Paris in 1957 and acknowledged that he had been a Soviet spy operating in the United States for the preceding five years.
The case of Abel
His defection revealed a wealth of information on Soviet infiltration techniques, including years of English language study, instruction in document photography, message encoding and decoding, and the creation of a fictitious identity based on a real surname that allowed the spy to pass as an immigrant son.
In addition, the FBI was ultimately able to decrypt the coin's message and identify and apprehend its commanding agent—whom Häyhänen only knew as "Mark," thanks to the keys he provided.
It concerned a professional photographer who’s flat contained many birth certificates belonging to various people.
His "real" identity (his true name was Vílyam Fisher) was one of the few things he disclosed during the interrogation: Rudolf Ivanovich Abel, a Soviet national.
Depending on what and how much we want to learn, history always has something to teach us.
