2500-year-old missing persons case solved?

Okay, this article is almost a year old, but I just found it: according to Herodotus, in 525 BC a Persian army crossing the desert en route to attack Greece vanished entirely in a massive sandstorm and were never found. Well, archaeologists may have found the army, or part of it anyway, buried in the sand right around the place where they were said to have vanished. The archaeologists sound awfully sure that these are the ones.
