Cambyses’ Lost Army and the Physics of Sandstorms

By Jennifer Ouellette | August 5, 2013

Over the weekend Jen-Luc Piquant found herself pondering the works of Herodotus, specifically the tale of the Lost Army of Cambyses. Sometime around 524 BC, priests at the oracle of the Temple of Amun decided they didn’t much care for their new ruler, Cambyses II, son of Cyrus the Great. Cambyses decided that he didn’t much care for their insubordination. And he had soldiers — 50,000 of them, sent marching through the Sahara from Thebes to put those rebellious priests in their place.

But they never reached their destination (the Oasis of Siwa, where the mutinous temple was located).  Seven days into their march, a massive sandstorm broke out and buried Cambyses’ entire army, never to be seen again. Per Herodotus: “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.”

It’s most likely myth, according to leading Egyptologists. But it inspired a cautionary mention of Cambyses in the prologue to Chaucer’s Canterbury Tales, when the Pardoner is advocating moderation in drinking alcohol (he seemed to think Cambyses dispatched his army in a drunken rage). And it also inspired various archaeological expeditions over the past 100 or so years to try and locate whatever evidence might remain of the lost army of the Egyptian ruler.

Persians in Egypt in the Achaemenid period

The last pharaoh of the Twenty-Sixth dynasty, Psamtik (Psammetichus) III, was defeated by Cambyses II (q.v.; 530-22 B.C.E.) in the battle of Pelusium in the eastern Nile delta in 525 B.C.E.; Egypt was then joined with Cyprus and Phoenicia in the sixth satrapy of the Achaemenid empire (Cook, p. 214; Bresciani, Camb. Hist. Iran, pp. 502-03; Briant, 1987; idem, 1992, p. 67). The “first Persian domination” over Egypt (or Twenty-Seventh dynasty) ended around 402 B.C.E. After an interval of independence, during which three indigenous dynasties reigned (the Twenty-Eighth, Twenty-Ninth, and Thirtieth; for the probable last ruler, Khababash, see Ritner; cf. Bresciani, 1990, pp. 637-41), Artaxerxes III (q.v.; 359-38 B.C.E.) reconquered the Nile valley for a brief period (342-32 B.C.E.), usually called the “second Persian domination.”

The first Persian domination. Cambyses led three unsuccessful military campaigns in Africa: against Carthage, the oases of the Libyan desert, and Nubia. He remained in Egypt until 522 B.C.E. and died on the way back to Persia. In contrast to the hostile tradition transmitted by Herodotus (3.64-66) and Diodorus Siculus (1.95), who described Cambyses’ conduct in Egypt as mad, ungodly, and cruel, contemporary Egyptian documents offer a different perspective on this sovereign’s “atrocities” (Posener, pp. 171 ff.; Klasens; Bresciani, Camb. Hist. Iran, pp. 504-05), even though violence and abuses perpetrated by the occupation troops can be taken for granted. Herodotus may have drawn on an indigenous tradition that reflected the Egyptian clergy’s resentment of Cambyses’ decree (known from a text in Demotic script on the back of papyrus no. 215 in the Bibliothèque Nationale, Paris) curtailing royal grants made to Egyptian temples under Amasis (Bresciani, 1981).
