The following in no small degree strengthens my conviction on this point; for not only did he send away the others, but it is certain that Leonidas also sent away the augur who followed the army, Megistias the Acarnanian, who was said to have been originally descended from Melampus, the same who announced, from an inspection of the victims, what was about to befall them, in order that he might not perish with them. He however, though dismissed, did not himself depart but sent away his son who served with him in the expedition, being his only child.
The allies that were dismissed, accordingly departed, and obeyed Leonidas, but only the Thespians and the Thebans remained with the Lacedaemonians; the Thebans, indeed, remained unwillingly and against their inclination, for Leonidas detained them, treating them as hostages; but the Thespians willingly, for they refused to go away and abandon Leonidas and those with him, but remained and died with them. Demophilus, son of Diadromas, commanded them.
Xerxes, after he had poured out libations at sunrise, having waited a short time, began his attack about the time of full market, for he had been so instructed by Ephialtes; for the descent from the mountain is more direct and the distance much shorter than the circuit and ascent. The barbarians, therefore, with Xerxes, advanced, and the Greeks with Leonidas, marching out as if for certain death, now advanced much farther than before into the wide part of the defile, for the fortification of the wall had protected them, and they on the preceding days, having taken up their position in the narrow part, fought there; but now engaging outside the narrows, great numbers of the barbarians fell; for the officers of the companies from behind, having scourges, flogged every man, constantly urging them forward; in consequence, many of them, falling into the sea, perished, and many more were trampled alive under foot by one another and no regard was paid to any that perished, for the Greeks, knowing that death awaited them at the hands of those who were going round the mountain, being desperate and regardless of their own lives, displayed the utmost possible valor against the barbarians.
