By and by Xerxes grew impatient and sent a horseman to reconnoitre. The horseman could not see the Spartan camp, for it was hidden by the old wall that had been repaired, but he could see the men themselves without the wall. Their arms were piled up against it in stacks, as though no enemy was near. Some of the soldiers were wrestling with each other, others were combing their hair, as if they were getting ready for a festival rather than for a battle. The Persian was astonished at what he saw. As the Spartans took no notice of him, he stayed to count their number, and then rode quietly back to tell Xerxes all that he had seen. Xerxes, too, was amazed. Why should soldiers trouble to comb their hair before fighting? Why should they wrestle with one another as though no danger lay before them? He thought that they were doing ‘childish and silly things,’ for he did not understand that this was the Spartans’ way of getting ready either to die or to slay their enemies. In the Persian camp was an exiled King of Sparta, named Demaratus. Xerxes sent for him to ask why his countrymen wasted their time, wrestling and combing their long curls. ‘These men,’ answered Demaratus, ‘are here to fight for the pass; and when they have to face a mortal danger, their custom is to comb and deck out their hair. Be sure then, that if thou canst conquer these and all the rest who remain behind in Sparta, there is no other nation which shall dare to raise a hand against thee, for now art thou face to face with the bravest men of all Hellas.’ But Xerxes laughed at the thought of a small band of men like the Spartans daring to fight against his great army. He dismissed Demaratus and sent to demand that the Spartans should give up their arms. But the only answer that Leonidas sent back was to bid the king ‘to come and take them.’ It was plain that the Spartans did not fear the enemy. When one of them was told that the Persian host was so numerous that ‘the flight of their arrows would darken the light of the sun,’ he answered carelessly, ‘So much the better, we shall fight in the shade.’ For four days Xerxes waited, expecting the Spartans to flee, but on the fifth day they were still there, wrestling and combing their hair as before. Then the king sent a band of soldiers to the enemy’s camp, bidding it take these bold Spartans alive and bring them bound into his presence. But the Persians could not push their way through the narrow gates which were guarded by the enemy. They were not only kept at bay, they were thrust back again and again, and many of their number were slain by the long spears of the Spartans. CHAPTER XLVII THE BATTLE OF THERMOPYLAE
