7.214.1
There is another story told, namely that Onetes son of Phanagoras, a Carystian, and Corydallus of Anticyra are the ones who gave the king this information and guided the Persians around the mountain, but I find it totally incredible.
7.214.2
One must judge by the fact that the Pylagori set a price not on Onetes and Corydallus but on Epialtes the Trachinian, and I suppose they had exact knowledge; furthermore, we know that Epialtes was banished on this charge.
7.214.3
Onetes might have known the path, although he was not a Malian, if he had often come to that country, but Epialtes was the one who guided them along the path around the mountain. It is he whom I put on record as guilty.
ch. 215
7.215.1
Xerxes was pleased by what Epialtes promised to accomplish. He immediately became overjoyed and sent out Hydarnes and the men under Hydarnes command, who set forth from the camp at about lamp-lighting time. This path note had been discovered by the native Malians, who used it to guide the Thessalians into Phocis when the Phocians had fenced off the pass with a wall and were sheltered from the war. So long ago the Malians had discovered that the pass was in no way a good thing. note
ch. 216
7.216.1
The course of the path is as follows: it begins at the river Asopus as it flows through the ravine, and this mountain and the path have the same name, Anopaea. This Anopaea stretches along the ridge of the mountain and ends at Alpenus, the Locrian city nearest to Malis, near the rock called Blackbuttock and the seats of the Cercopes, where it is narrowest. note
ch. 217
7.217.1
This, then, was the nature of the pass. The Persians crossed the Asopus and travelled all night along this path, with the Oetaean mountains on their right and the Trachinian on their left. At dawn they came to the summit of the pass.
7.217.2
In this part of the mountain one thousand armed men of the Phocians were on watch, as I have already shown, defending their own country and guarding the path. The lower pass was held by those I have mentioned, but the Phocians had voluntarily promised Leonidas to guard the path over the mountain.
ch. 218
7.218.1
The Phocians learned in the following way that the Persians had climbed up: they had ascended without the Phocians' notice because the mountain was entirely covered with oak trees. Although there was no wind, a great noise arose like leaves being trodden underfoot. The Phocians jumped up and began to put on their weapons, and in a moment the barbarians were there.
7.218.2
When they saw the men arming themselves, they were amazed, for they had supposed that no opposition would appear, but they had now met with an army. Hydarnes feared that the Phocians might be Lacedaemonians and asked Epialtes what country the army was from. When he had established what he wanted to know with certainty, he arrayed the Persians for battle.
7.218.3
The Phocians, assailed by thick showers of arrows and supposing that the Persians had set out against them from the start, fled to the top of the mountain and prepared to meet their destruction. This is what they intended, but the Persians with Epialtes and Hydarnes paid no attention to the Phocians and went down the mountain as fast as possible.
ch. 219
7.219.1
The seer Megistias, examining the sacrifices, first told the Hellenes at Thermopylae that death was coming to them with the dawn. Then deserters came who announced the circuit made by the Persians. These gave their signals while it was still night; a third report came from the watchers running down from the heights at dawn.
