In an exclusive first reported by Fox News, a series of documents released by Argentine President Javier Milei last year unveils the intriguing narrative of Nazi war criminals who managed to evade capture while residing in Argentina. These individuals, who sought refuge during and after World War II, largely lived undisturbed lives, shielded by a government that initially harbored sympathetic ties to them.

During the era of Argentina’s Peronist government, authorities were not only aware of the presence of Nazi criminals within their borders but often facilitated their concealment. However, once this populist regime crumbled, the South American nation made lukewarm attempts to monitor these war criminals, yet significant outcomes were scarce.

One of the more telling examples of this lackluster pursuit is the case of Martin Bormann, a key figure within Hitler’s inner circle. Despite the notoriety of his role, Argentina’s efforts to investigate and apprehend him faltered, highlighting the inefficiencies that plagued their pursuit of justice.

Martin Bormann, who wielded substantial power behind the scenes, was instrumental in shaping Nazi policy and governance. As Hitler’s private secretary and the head of the Nazi Party Chancellery, he controlled the flow of information to Hitler and determined who could access the dictator, a testament to his significant influence despite his low public profile.

Bormann was one of the most powerful figures in the Nazi regime, despite his relatively low profile in the public. He used his position as private secretary to Hitler and head of the Nazi Party Chancellery to control the flow of documents personally received by Hitler and who had access to him.

Through enormous administrative influence, he shaped policy and controlled what Hitler saw, who he met, and advised on major decisions. Bormann supported extreme antisemitic measures and was one of the masterminds of the Aryanization project. Bormann disappeared in May 1945 during the fall of Berlin. For decades, it was speculated he had fled to Argentina along the ratlines — escape routes facilitated by Nazi sympathizers. Bormann was sentenced to death in absentia during the Nuremberg Trials.

The files show that Bormann was one of the very few Nazis the Argentinians actively tried to pursue and bring to justice. However, most of the leads came from sensationalist press articles often devoid of factual and actionable intelligence beyond the mere mention that he was hiding in Argentina.

The files meticulously depict intelligence agencies trying to corroborate such reports and assert whether the floated false aliases matched the actual man in Argentina. Agencies followed information coming from reports in the Argentine, U.S., British and Brazilian press, along with some translations from German-language media published in Argentina by the émigré community who were suspected of harboring Nazi sympathizers.

The articles triggered extensive paper trails between the ministry of justice, intelligence bodies, border and customs agencies, the federal police, and local authorities, but were often disconnected from one another, or took a long time to be referred to the various sub-offices for action.

As a result, multiple similar searches were carried out at various points haphazardly and a tangle of bureaucracy made authorities play catch up to press reports rather than conducting independent and rational investigations. The files are a testament that the hunt for Nazis in South America was shaped by rumor, miscommunication, mistaken identities, Cold War politics and intense media speculation.

Some of the information reviewed by Fox News Digital showed authorities took rumors such as a hunt for Bormann in the jungles of Peru, Colombia and Brazil as credible. A case of an elderly German man detained in Colombia in 1972 as Bormann (later cleared and released) despite voiced skepticism by Nazi-hunter Simon Wiesenthal is also part of the files.

The diplomatic shockwaves that followed Israel’s Mossad seizing Adolf Eichmann in Argentina left local officials acutely sensitive to international scrutiny, recasting the search for Bormann as a bid to ensure the country would not be embarrassed on the world stage a second time.

A pivotal—and ultimately flawed—lead in the Bormann files emerged in 1955, when police, relying on fading testimonies about an illegal German laborer, along with rumors, seized correspondence, and aging witnesses, began pursuing a man named Walter Wilhelm Flegel.

Flegel had arrived through Chile, was missing an arm due to an accident, and had been previously arrested and brought to court twice on assault and robbery charges. Suspicions led to his arrest in Mendoza in 1960 despite his complete dissemblance, lack of education, long presence in the country, age gaps and missing factual connections that could tie him to Martin Bormann. Notwithstanding such mismatching profiles — and fingerprints — it still took a week for Argentinians to be convinced Flegel was not Martin Bormann and free him.

Ultimately, despite continued rumors, and Argentina’s singular resolve in finally arresting one of the many Nazi fugitives thought to be in the country, human remains found in Berlin in 1972 were a match and confirmed Bormann’s death during the city’s fall through dental and cranial records. Later, in the 1990s, further DNA testing confirmed the remains found in Berlin indeed belonged to Bormann, bringing the misdirected Argentinian search finally to a close
