EXCLUSIVE FROM FOX: A series of documents unveiled by Argentine President Javier Milei last year shed light on Argentina’s historical pursuit of Nazi war criminals who sought refuge within its borders during and after World War II. These documents illustrate how many of these individuals managed to evade capture and largely live untroubled lives.

During the era of Argentina’s Peronist government, there was a degree of sympathy for these Nazi fugitives, and authorities were often aware of their presence. However, after the fall of the populist regime, Argentina’s efforts to track these war criminals were notably lackluster.

Among several high-profile cases that stalled, the investigation into Martin Bormann, a key figure in Hitler’s inner circle, highlights Argentina’s inefficiency in handling such matters.

Despite his low public profile, Bormann wielded significant power within the Nazi hierarchy. As Hitler’s private secretary and head of the Nazi Party Chancellery, he controlled the documents reaching Hitler and determined who had access to him. His administrative prowess allowed him to influence policies, and he was pivotal in implementing extreme antisemitic measures and orchestrating the Aryanization project.

Bormann vanished in May 1945 during Berlin’s collapse. For years, rumors persisted that he escaped to Argentina via the ratlines, escape routes organized by Nazi sympathizers. He was sentenced to death in absentia during the Nuremberg Trials, yet his fate remained the subject of speculation for decades.

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
