Is the Mystery of the Lost Persian Army Finally Unraveled?

The final resting place of a 50,000-strong Persian army which was swallowed up in a cataclysmic sandstorm in the Sahara Desert around 524 BC is one of the greatest mysteries in ancient history. Many, over the years, have claimed to have found the lost army, but most have been proven to be hoaxes. Recently, a Dutch archaeologists claimed to have solved the mystery of what happened to the ill-fated army some 2,500 years ago.

According to the Greek historian Herodotus, Cambyses II, the oldest son of Cyrus the Great, King of Persia, sent his army to destroy the Oracle of Amun at Siwa Oasis after the priests there refused to legitimize his claim to Egypt. The army of 50,000 men entered Egypt’s western desert near Luxor but halfway through, a massive sandstorm sprang up and reportedly buried them all.



“A wind arose from the south, strong and deadly, bringing with it vast columns of whirling sand, which entirely covered up the troops and caused them wholly to disappear,” wrote Herodotus.

Although many Egyptologists regard the story as a myth, many expeditions have taken place in search of the remains of the lost soldiers. Most came back completely empty-handed, while others claiming to have found the remains have been proven false.

In 2009, two Italian archaeologists announced that they located human remains, tools and weapons near Siwa Oasis in Egypt dating to the age in which the army disappeared. However, this too is questionable and has been dismissed by many scholars on the basis of the fact that they chose to announce them in a documentary film rather than a scientific journal. Furthermore, the two researchers also happen to be the filmmakers who produced five controversial African shockumentaries in the 1970s.

Professor Olaf Kaper, an archaeologist at Leiden University in the Netherlands, believes he knows what really happened to the lost army. “Some expect to find an entire army, fully equipped. However, experience has long shown that you cannot die from a sandstorm,” said Kaper, as reported by Sci-News.

Professor Kaper argues that the lost army of Cambyses II did not disappear, but was defeated. According to Kaper, the army’s final destination was the Dakhla Oasis – the location of the troops of the Egyptian rebel leader Petubastis III.



“He ultimately ambushed the army of Cambyses II, and in this way managed from his base in the oasis to reconquer a large part of Egypt, after which he let himself be crowned Pharaoh in the capital, Memphis.”

Kaper maintains that the fate of the army remained unclear for such a long time because the Persian King Darius I, who ended the Egyptian revolt two years after Cambyses II’s defeat, attributed the embarrassing defeat of his predecessor to a sandstorm in order to save face, and this became the accepted account of what happened.

Excavations in the Dakhla Oasis have revealed titles of the Egyptian rebel leader Petubastis III carved on ancient temple blocks, which suggests that it was a stronghold at the start of the Persian period. Hopefully further work will be undertaken to follow up this promising lead, which may solve one of archaeology’s biggest outstanding mysteries.
