Xerxes is said to have leapt thrice from his throne as the wave of disturbance reached him, fearing for his whole army. On the third day a native guide came and told the king of a pass over the mountains, by which the Greeks might be taken in rear, and he selected Hydarnes, the commander of the Immortals, for this important service. The crest of this pass (the existence of which the Greeks had learned too late) was watched on their behalf by a thousand Phocians, who were warned by hearing the rustling of the dry leaves of the oak-wood, but thinking an attack on their own post was intended, retired to a more defensible position, and let Hydarnes pass on. The way in which the little band of heroes received the announcement that their position had been turned should be told in Herodotus's own words:—
"First, the soothsayer Megistias, as he inspected the sacrifices, warned them of the death which awaited them with the morrow's dawn. Then came some deserters, who told them of the march of the Persians round the hill. All this was while it was still night. Then, when the day had broken, their scouts came running down from the heights with the same news. Thereupon the Greeks took counsel, and their opinions were divided: for some would not hear of quitting their post, while others advised to do so. Then they parted asunder, and some went off and dispersed each to their own cities, and some prepared to remain there with Leonidas. It is even said that Leonidas himself sent them away, anxious that they should not be slain; but for himself and the Spartans who were there, it was not seemly, he said, for them to leave a post which they had once undertaken to keep."
