In the midst of the perplexity which pervaded the king's councils after this defeat, there arrived at the Persian camp one Ephialtes, a Malian. Influenced by the hope of a great reward, this traitor demanded and obtained an audience, in which he offered to conduct the Medes through a secret path across the mountains, into the pass. The offer was joyfully accepted, and Hydarnes, with the forces under his command, was despatched under the guidance of the Malian. At the dusk of evening the detachment left the camp, and marching all night, from the river Asopus, between the mountains of Oeta on the right hand, and the Trachinian ridges on the left, they found themselves at the early dawn at the summit of the hill, on which a thousand Phocians had been stationed to defend the pass, for it was not unknown to the Spartans. In the silence of dawn they wound through the thick groves of oak that clad the ascent, and concealed the glitter of their arms; but the exceeding stillness of the air occasioned the noise they made in trampling on the leaves [65] to reach the ears of the Phocians. That band sprang up from the earth on which they had slept, to the consternation and surprise of the invaders, and precipitately betook themselves to arms. The Persians, though unprepared for an enemy at this spot, drew up in battle array, and the heavy onslaught of their arrows drove the Phocians to seek a better shelter up the mountains, not imagining that the passage into the defile, but their own destruction, was the object of the enterprise. The Persians prudently forbore pursuit, but availing themselves of the path now open to their progress, rapidly descended the opposite side of the mountain. IX. Meanwhile, dark and superstitious terrors were at work in the Grecian camp. The preceding eve the soothsayer (Megistias) had inspected the entrails, and foretold that death awaited the defenders of Thermopylae in the morning; and on that fatal night a Cumaean deserted from the Persian camp had joined Leonidas, and informed him of the treachery of Ephialtes. At early day their fears were confirmed by the sentinels posted on the mountains, who fled into the defile at the approach of the barbarians. A hasty council was assembled; some were for remaining, some for flight. The council ended with the resolution of a general retreat, probably with the assent, possibly by the instances, of Leonidas, who was contented to possess the monopoly of glory and of death. The laws of the Spartans forbade them to fly from any enemy, however numerous, and Leonidas did not venture to disobey them. Perhaps his resolution was strengthened by an oracle of that Delphi so peculiarly venerated by the Dorian race, and which foretold either the fall of Sparta, or the sacrifice of a Spartan king of the blood of Hercules. To men whose whole happiness was renown, life had no temptation equal to such a death!
