Among the Grecian allies of Mardonius, the Thebans and Bœotians were active and zealous, most of the remainder lukewarm, and the Phocians even of doubtful fidelity. Their contingent of one thousand hoplites, under Harmokydês, had been tardy in joining him, having only come up since he retired from Attica into Bœotia: and some of the Phocians even remained behind in the neighborhood of Parnassus, prosecuting manifest hostilities against the Persians. Aware of the feeling among this contingent, which the Thessalians took care to place before him in an unfavorable point of view, Mardonius determined to impress upon them a lesson of intimidation. Causing them to form in a separate body on the plain, he then brought up his numerous cavalry all around them: while the phêmê, or sudden simultaneous impression, ran through the Greek allies as well as the Phocians themselves, that he was about to shoot them down.[322] The general Harmokydês, directing his men to form a square and close their ranks, addressed to them short exhortations to sell their lives dearly, and to behave like brave Greeks against barbarian assassins,—when the cavalry rode up, apparently to the charge, and advanced close to the square, with uplifted javelins and arrows on the string, some few of which were even actually discharged. The Phocians maintained, as enjoined, steady ranks with a firm countenance, and the cavalry wheeled about without any actual attack or damage. After this mysterious demonstration, Mardonius condescended to compliment the Phocians on their courage, and to assure them, by means of a herald, that he had been greatly misinformed respecting them: he at the same time exhorted them to be faithful and forward in service for the future, and promised that all good behavior should be amply recompensed. Herodotus seems uncertain,—difficult as the supposition is to entertain,—whether Mardonius did not really intend at first to massacre the Phocians in the field, and desisted from the intention only on seeing how much blood it would cost to accomplish. However this may be, the scene itself was a remarkable reality, and presented one among many other proofs of the lukewarmness and suspicious fidelity of the army.[323] [322] Herodot. ix, 17. διεξῆλθε φήμη, ὡς κατακοντιεῖ σφέας. Respecting φήμη, see a note a little farther on, at the battle of Mykalê, in this same chapter. Compare the case of the Delians at Adramyttium, surrounded and slain with missiles by the Persian satrap, though not his enemies—περιστήσας τοὺς ἑαυτοῦ κατηκόντισε (Thucyd. viii, 108). [323] Οὐκ ἔχω δ’ ἀτρεκέως εἰπεῖν, οὔτε εἰ ἦλθον μὲν ἀπολέοντες τοὺς Φωκέας, δεηθέντων τῶν Θεσσαλῶν, etc. (Herodot. ix, 18.) This confession of uncertainty as to motives and plans, distinguishing between them and the visible facts which he is describing, is not without importance as strengthening our confidence in the historian.
