In 524 B.C., the army of Persian King Cambyses II moved against the Ethiopians. Over 50,000 soldiers went to conquer the oases, but all of them vanished without a trace, leaving only a legend behind.

It’s been only recently that the scientists Angelo and Alfredo Castiglioni have found the remains of the legendary army, proving that during their 13 years of hard work the warriors didn’t just disappear but were killed in a violent sandstorm.
