The vicinity of Xerxes, the absence of the re-enforcements they expected, produced an alarmed and anxious council; Leonidas dissuaded the confederates from retreat, and despatched messengers to the various states, urging the necessity of supplies, and stating the hopelessness of opposing the Mede effectually with the present forces. Xerxes, in the meanwhile, who had heard that an insignificant band were assembled under a Spartan descendant of Hercules, to resist his progress, despatched a spy to reconnoitre their number and their movements. The emissary was able only to inspect those without the intrenchment, who, at that time, happened to be the Spartans; he found that singular race engaged in gymnastic exercises, and dressing their long hair for the festival of battle. Although they perceived the spy, they suffered him to gaze at his leisure, and he returned in safety to the king. Much astonished at the account he received, Xerxes sent for Demaratus, and detailing to him what the messenger had seen, inquired what it might portend, and whether this handful of men amusing themselves in the defile could seriously mean to resist his arms. "Sire," answered the Spartan, "it is their intention to dispute the pass, and what your messenger has seen proves that they are preparing accordingly. It is the custom of the Spartans to adorn their hair on the eve of any enterprise of danger. You are advancing to attack the flower of the Grecian valour." Xerxes, still incredulous that opposition could be seriously intended, had the courtesy to wait four days to give the enemy leisure to retreat; in the interim he despatched a messenger to Leonidas, demanding his arms. "Come and take them!" replied the Spartan. VIII. On the fifth day the patience of Xerxes was exhausted, and he sent a detachment of Medes and Cissians [64] into the pass, with orders to bring its rash and obstinate defenders alive into his presence. The Medes and Cissians were repulsed with considerable loss. "The Immortal Band" were now ordered to advance, under the command of Hydarnes. But even the skill and courage of that warlike troop were equally unsuccessful; their numbers were crippled by the narrowness of the pass, and their short weapons coped to great disadvantage with the long spears of the Greeks. The engagement was renewed a second day with the like fortune; the loss of the Persians was great, although the scanty numbers of the Spartans were also somewhat diminished.
