So fared the expedition against Ethiopia. As for those who were sent to march against the Ammonians, they set out and journeyed from Thebes with guides; and it is known that they came to the city of Oasis,1 inhabited by Samians said to be of the Aeschrionian tribe, seven days' march from Thebes across sandy desert; this place is called, in the Greek language, Islands of the Blest. [2] Thus far, it is said, the army came; after that, except for the Ammonians themselves and those who heard from them, no man can say anything of them; for they neither reached the Ammonians nor returned back. [3] But this is what the Ammonians themselves say: when the Persians were crossing the sand from Oasis to attack them, and were about midway between their country and Oasis, while they were breakfasting a great and violent south wind arose, which buried them in the masses of sand which it bore; and so they disappeared from sight. Such is the Ammonian tale about this army.
