The secrets of missing expeditions are one of the most popular subjects of myths, urban legends, literary works and films. The very disappearance of people prepared for extreme situations is a source of much speculation. A striking example- “The Flying Dutchman”, but even in modern times there are plenty of such stories.
Polar explorers and explorers of the African jungle, South America or Asia, scientists who went in search of secrets, pioneers and groups of treasure hunters... Dangerous journeys often ended with the mysterious disappearance of such expeditions in their entirety.
Rescue measures in some cases do not lead to any results - there is no trace of expeditions to hard-to-reach or dangerous places.
In our small selection we will talk about seven mysteriously missing expeditions and some of the most likely versions of their mysterious disappearance.
La Perouse's expedition around the world
On August 1, 1785, the Comte de La Perouse set out on a risky voyage on the ships Boussol and Astrolabe. trip around the world, to systematize the discoveries made by Cook and establish trade relations with the native tribes.
During the first year of his journey, La Perouse rounded Cape Horn, visited Chile, Easter Island, and in July 1786 reached Alaska.
The following year, the explorer arrived on the shores of Northeast Asia and discovered the island of Kelpaert there.
Then the expedition moved to Sakhalin - finding a strait that now bears the name of the count. At the end of 1787, La Perouse was already off the coast of Samoa, where he lost 12 people in a skirmish with savages.
In the winter of 1788, the expedition transmitted the last message to their homeland through British sailors. Nobody saw them again. Only in 2005 was it possible to reliably identify the site of the shipwreck, but the fate of La Perouse is still unknown. Most of his records also perished with him.
"Terror" and "Erebus" (Franklin's expedition)
These two British ships, with 129 people on board, left Greenhithe Wharf one morning in May 1845. Under the leadership of Sir John Franklin, they intended to explore the latter white spot on a map of the Canadian Arctic and complete the discovery of the Northwest Passage.
For 170 years now, the fate of this expedition has haunted scientists and writers.
But all that was discovered during this time was only a few graves and two wintering camps.
Based on the findings, it was concluded that the ships were frozen in ice, and the crew, suffering from scurvy, pneumonia, tuberculosis and terrible cold, did not disdain cannibalism.
Walking across Australia (Leichhardt expedition)
On April 4, 1848, German explorer Ludwig Leichhardt set out with eight companions. He planned to cross the Australian mainland from east to west on foot in three years.
However, after the agreed time, none of the members of this expedition showed up. In 1852, the first team set out to search, followed by the second, then the third, and so on for seventeen years in a row.
Until one tramp wandering around the mainland accidentally mentioned that he lived for several months on the banks of the Muligan River with a certain Adolf Klassen.
When he found out that this was one of those whom they had been looking for for so long, he went in search of him, but died on the way.
And only after a long time it became clear that Klassen had lived in captivity among savages for almost thirty years. They killed him around 1876. The last hope of learning about the fate of Leichhardt and his expedition also died with him.
In search of Arctida (Toll's expedition)
In 1900, Baron Eduard Vasilyevich Toll set out on an expedition on the schooner Zarya to search for new islands in the Arctic. Toll also firmly believed in the existence of the so-called Sannikov Land and wanted to become its discoverer.
In July 1902, the baron, accompanied by astronomer Friedrich Seeberg and two hunters Vasily Gorokhov and Nikolai Dyakonov, left the schooner to reach the coveted Arctida on sleighs and boats.
Zarya was supposed to arrive there in two months.
However, due to poor ice conditions, the ship was damaged and was forced to leave for Tiksi. The next year, under the leadership of then-lieutenant Kolchak, a rescue expedition was assembled.
They discovered Toll's site, as well as his diaries and notes. It followed from them that the researchers decided not to wait for “Dawn” and continued on their own. Other traces of these four people never found.
"Hercules" (Rusanov's expedition)
“Hercules” was a small hunting vessel, on which in 1912, experienced polar explorer Vladimir Aleksandrovich Rusanov, together with members of his expedition, went to the island of Spitsbergen in order to secure Russia’s right to extract minerals there before other countries.
Everything went well. But for unknown reasons, Rusanov decided to return through the northwestern tip of Novaya Zemlya, and if the ship survived, then go east to the first island he encountered. A telegram with his intentions was the last news from Hercules.
Only in 1934, on one of the islands near the shore of Khariton Laptev, a pillar with the carved inscription “Hercules 1913” was discovered. And on the neighboring island things from Hercules were found: a nautical book, notes, pieces of clothing, etc. But the bodies of the expedition members were never found.
Main Objective "Z" (Fawcett Expedition)
In 1925, in the vast expanses of the poorly studied region of Mato Grosso, an expedition of three people disappeared: Colonel Percival Fawcett, his son Jack and their friend Reilly Reymilom. They all went in search of a certain lost city, which Fossett himself called “Z”.
Much of this expedition is shrouded in mystery. It was financed by a certain group of London entrepreneurs called the Glove.
The colonel himself, in case of loss, asked not to look for them, since all expeditions would suffer the same fate.
IN last message a group of researchers described how they made their way through thickets, climbed mountains and crossed rivers and that, in fact, it was all very boring.
Nobody heard anything more about these three people. Now there are various rumors, starting with the fact that they were all eaten by Indian cannibals, which are not uncommon here, and ending with the fact that Fawcett found the city of “Z”, met its inhabitants and did not want to go back.
Leontiev Group
In the summer of 1953, communication with the Tuvan expedition of Lev Nikolaevich Leontyev was interrupted. At the site of her last stop, searchers found a still smoldering fire, tents and a full set of equipment.
However, there were no people or horses in the camp. The only hoof prints led from the forest to the camp. All nearby expeditions set out to search. But they ended in failure. Leontyev’s group is still listed as missing, and many theories related to its disappearance are still circulating on the Internet.
The disappearance of an entire expedition is always a mystery. Trained people, polar explorers, tropical explorers, pioneers - disappeared under mysterious circumstances. Traces of some groups were never found...
