# A secret Nazi base survived in Antarctica after the war, and the US Navy's 1946-47 Operation Highjump was a failed military assault on it, tied to the hollow earth

**Verdict: Contradicted.** Two things here are real and documented, and the legend welds them together. Nazi Germany did send an expedition to Antarctica in 1938-39, mapping a stretch of Dronning Maud Land it called Neuschwabenland; and the US Navy really did run a large Antarctic operation, Highjump, in 1946-47 under Rear Admiral Richard Byrd. The rated claim is the fantasy built on top of that record: that the Germans left behind a hidden fortress (Base 211 or New Berchtesgaden), that Hitler or advanced flying saucers survived there, sometimes reached through a hollow earth, and that Highjump was a secret military attack on the base that was beaten back. That claim is debunked. The German visit was fleeting and whaling-focused, no base was ever built or found, the two U-boats said to have supplied it could not physically have reached the coast, Highjump was a cold-weather training and mapping exercise cut short by the closing Antarctic summer, and the hollow-earth flourishes trace to a forged diary and neo-Nazi pamphlets, not to any evidence.

## Summary
The story braids two genuine historical events into a single myth. In the summer of 1938-39, a German expedition aboard the ship Schwabenland flew over and photographed part of Dronning Maud Land, dropped marker darts, and named the region Neuschwabenland. Seven years later, in 1946-47, the US Navy mounted Operation Highjump, a fleet-scale expedition of thousands of men, thirteen ships, and dozens of aircraft under Rear Admiral Richard Byrd, to train for polar conditions and map the continent from the air. From these facts the legend grows a secret survival: a hidden Nazi stronghold, Base 211, carved into the ice; escaping U-boats carrying senior Nazis or Hitler himself; a fleet of advanced disc-shaped aircraft; sometimes an entrance to a warm, inhabited hollow earth; and a reading of Highjump not as science and training but as a botched military assault on the base, driven off by superior technology and hushed up ever since. This case file keeps the documented record (a real German mapping flight and a real US Navy expedition) apart from the rated claim (a surviving Nazi fortress, saucers, and hollow-earth war), which is debunked.

## The claim
That Nazi Germany secretly built and garrisoned a base in Antarctica (variously Base 211 or New Berchtesgaden) that outlived the Third Reich; that U-boats carried leading Nazis, possibly Hitler and Eva Braun, there after the war; that the base housed advanced flying-saucer craft and sometimes connected to a habitable hollow earth; and that the US Navy's Operation Highjump in 1946-47 was a covert military assault on this stronghold that was repelled by the base's superior technology and has been covered up ever since.

## Origin and timeline
- 1938-1939: A German expedition led by Alfred Ritscher sails to Antarctica aboard the ship Schwabenland. Two Dornier seaplanes, Boreas and Passat, are catapult-launched to photograph roughly 11,600 aerial images of the coast and hinterland of Dronning Maud Land. The team drops metal marker darts stamped with the swastika, names the region Neuschwabenland, and departs after a few weeks. No landing party stays more than hours, and no base or whaling station is built.
- 1945-07: The German submarine U-530 reaches Mar del Plata, Argentina, and surrenders on 10 July 1945, more than two months after Germany's capitulation. U-977 surrenders there on 17 August. The long delay and the ambiguity of the war's end fuel rumors that the boats had first carried fugitives to a hidden destination.
- 1945-1947: Ladislas Szabo, a Hungarian exile in Argentina, publishes newspaper articles and later a book (Hitler Is Alive) claiming a U-boat convoy had ferried Hitler and other Nazis to a secret Antarctic refuge before surrendering. The base and the convoy appear nowhere before Szabo's writing; he supplies the founding narrative from which the later legend is built.
- 1946-08: The US Navy launches Operation Highjump, officially the United States Navy Antarctic Developments Program, 1946-47. Task Force 68 comprises about 4,700 men, 13 ships (including the aircraft carrier USS Philippine Sea and a submarine), and 33 aircraft, organized by Rear Admiral Richard Byrd and commanded by Rear Admiral Richard Cruzen. Its stated goals are to establish the Little America IV base, train personnel and test equipment in polar conditions, and map the continent from the air.
- 1947-02: Highjump ends in late February 1947, weeks earlier than some had hoped, as the Antarctic summer closes and thickening sea ice threatens to trap the ships. The expedition maps over a million square miles and takes tens of thousands of aerial photographs. Its handful of deaths are attributed to an aircraft crash in whiteout conditions and other accidents, not combat.
- 1947-03: Chilean newspaper El Mercurio publishes remarks attributed to Byrd, via correspondent Lee van Atta, warning that the United States must prepare against aircraft able to fly from pole to pole at great speed. In context Byrd is describing the strategic vulnerability of the poles to a future Soviet attack over the Arctic. The line is later mistranslated and recast as an admission of hostile flying saucers.
- 1950s-1960s: Hollow-earth and fringe writers, including the pseudonymous Raymond Bernard (the American Walter Siegmeister), publish claims that Byrd flew into a warm land beyond the pole and a secret diary that Byrd never wrote. These texts graft the hollow-earth motif onto the Antarctic story and onto Byrd personally.
- 1970s-1980s: Authors writing as Mattern and Friedrich, the latter a pen name of neo-Nazi publisher Ernst Zundel, fuse the strands into the modern legend: a surviving Base 211, Nazi saucer fleets, and Highjump as a failed assault. The tale spreads through UFO circles and, later, the internet, where it is still repeated.

## The evidence, claim by claim
- Claim: The 1938-39 German expedition built a permanent secret base, Base 211, in Neuschwabenland.
  Evidence: The expedition is real and well documented, and what it did is the opposite of base-building. The Schwabenland party spent only a few weeks off the coast in early 1939, its work was aerial photography and mapping plus dropping marker darts, and its practical aim was to scout a site for a whaling station to reduce German dependence on imported whale oil. No landing party remained more than hours. No structure was ever built, and none has ever been found in the eighty-plus years since, despite the region being surveyed by later expeditions. Base 211 first appears in postwar storytelling, not in any expedition record.
- Claim: Surrendering U-boats carried Hitler or senior Nazis to the Antarctic base after the war.
  Evidence: The two boats at the center of the story, U-530 and U-977, were interrogated at length after they surrendered in Argentina by Argentine, American, and British officers, who all concluded the arrivals were innocuous and that no fugitives had been aboard. Their tracks were reconstructed: when Germany capitulated U-530 was off New York and U-977 off Norway, and their slow, fuel-conserving voyages account for the time they took to reach Argentina with no room for an Antarctic detour. Reaching the coast would have required diving under pack ice far longer and deeper than the boats could manage. The escape narrative traces to Ladislas Szabo's articles, not to evidence.
- Claim: Operation Highjump was a secret military assault on the Nazi base that was defeated and covered up.
  Evidence: Highjump was a publicly announced, extensively documented US Navy expedition whose purpose was to establish a base, train men and machines for cold-weather and polar operations (with an eye to the emerging Cold War), and photograph and chart the continent. It was covered by embedded journalists and later dramatized in the Oscar-winning documentary The Secret Land, made from the expedition's own footage. It ended early because the Antarctic summer was closing and the ships risked being frozen in, not because it met resistance. The scholarly reconstruction by Summerhayes and Beeching found no attack, no battle, and no base to attack.
- Claim: Byrd publicly admitted the mission faced enemy aircraft that could fly pole to pole, proving hostile craft.
  Evidence: The quote is genuine but has been stripped of its meaning. Speaking to El Mercurio in 1947, Byrd warned that the United States needed to prepare for the possibility of aircraft attacking across the poles, a plain reference to the strategic reality that, in a future war, an enemy (the Soviet Union) could strike over the Arctic. It was a Cold War geography lesson, not a report of flying saucers. The saucer reading depends on a mistranslation and on quoting the line without its context.
- Claim: Byrd's secret diary describes flying into a warm, inhabited land through an opening at the pole, the hollow earth.
  Evidence: There is no such authentic diary. The hollow-earth Byrd material traces to fringe authors, above all the pseudonymous Raymond Bernard (Walter Siegmeister), a promoter of hollow-earth and related ideas, and to later pamphlets that put words in Byrd's mouth. The texts cite no original source and reproduce no verifiable manuscript. The hollow earth itself is contradicted by more than a century of seismology and gravimetry, which show a dense, layered, solid-and-molten interior with no habitable cavity.

## Why people believe it
- It starts from real history. There genuinely was a Nazi expedition that mapped and named part of Antarctica, and there genuinely was a large US Navy operation there in 1946-47 led by a famous admiral. A legend anchored to two verifiable events feels far more credible than one invented from nothing, and the true parts lend borrowed weight to the false ones.
- Antarctica is the perfect blank slate. It is vast, white, nearly empty, hard to reach, and easy to imagine as hiding something. A place most people will never see, and cannot easily check, invites the mind to fill it with fortresses and secret doors in a way a suburb never could.
- Nazi survival is an enduring fantasy. The idea that the Reich did not truly end, that Hitler slipped away and a redoubt held out, answers a wish (or a dread) that a defeated evil secretly persists. The Antarctic base is one of several escape myths, alongside South American hideouts, that keep that fantasy alive.
- Real secrecy and real technology give it texture. Cold War militaries did keep secrets, and Germany really did develop advanced aircraft and rockets late in the war. Stretching genuine wartime engineering into flying saucers, and genuine military reticence into a cover-up, feels like extrapolation rather than invention.
- It has been amplified and repackaged for decades. From Szabo's 1940s articles to Zundel's pamphlets to modern documentaries and viral posts, the story has been retold so often, with confident detail, that its very familiarity reads as corroboration, even though the retellings mostly cite one another.

## Open questions
- Why Germany bothered to formally decree a Neuschwabenland sector at all, and what strategic or symbolic weight the Reich placed on the fleeting 1939 expedition, is a genuine question of history, though it bears on ambition and propaganda, not on any base that was actually built.
- How much the mistranslated Byrd interview and the closing-summer early end of Highjump each contributed to the legend, versus the deliberate mythmaking of later authors, is a fair question about how such stories assemble themselves from real fragments.
- Why the Nazi-survival myth attaches so readily to Antarctica in particular, rather than fading like most wartime rumors, is a question about the psychology of blank, unreachable places and the long afterlife of the fantasy that a defeated regime endures somewhere out of sight.
