After this skirmishing had lasted some little while, the Lacedaemonians became unable to dash out with the same rapidity as before upon the points attacked, and the light troops finding that they now fought with less vigour, became more confident. They could see with their own eyes that they were many times more numerous than the enemy; they were now more familiar with his aspect and found him less terrible, the result not having justified the apprehensions which they had suffered, when they first landed in slavish dismay at the idea of attacking Lacedaemonians; and accordingly their fear changing to disdain, they now rushed all together with loud shouts upon them, and pelted them with stones, darts, and arrows, whichever came first to hand. The shouting accompanying their onset confounded the Lacedaemonians, unaccustomed to this mode of fighting; dust rose from the newly burnt wood, and it was impossible to see in front of one with the arrows and stones flying through clouds of dust from the hands of numerous assailants. The Lacedaemonians had now to sustain a rude conflict; their caps would not keep out the arrows, darts had broken off in the armour of the wounded, while they themselves were helpless for offence, being prevented from using their eyes to see what was before them, and unable to hear the words of command for the hubbub raised by the enemy; danger encompassed them on every side, and there was no hope of any means of defence or safety.
At last, after many had been already wounded in the confined space in which they were fighting, they formed in close order and retired on the fort at the end of the island, which was not far off, and to their friends who held it. The moment they gave way, the light troops became bolder and pressed upon them, shouting louder than ever, and killed as many as they came up with in their retreat, but most of the Lacedaemonians made good their escape to the fort, and with the garrison in it ranged themselves all along its whole extent to repulse the enemy wherever it was assailable. The Athenians pursuing, unable to surround and hem them in, owing to the strength of the ground, attacked them in front and tried to storm the position. For a long time, indeed for most of the day, both sides held out against all the torments of the battle, thirst, and sun, the one endeavouring to drive the enemy from the high ground, the other to maintain himself upon it, it being now more easy for the Lacedaemonians to defend themselves than before, as they could not be surrounded on the flanks.
The struggle began to seem endless, when the commander of the Messenians came to Cleon and Demosthenes, and told them that they were losing their labour: but if they would give him some archers and light troops to go round on the enemy's rear by a way he would undertake to find, he thought he could force the approach. Upon receiving what he asked for, he started from a point out of sight in order not to be seen by the enemy, and creeping on wherever the precipices of the island permitted, and where the Lacedaemonians, trusting to the strength of the ground, kept no guard, succeeded after the greatest difficulty in getting round without their seeing him, and suddenly appeared on the high ground in their rear, to the dismay of the surprised enemy and the still greater joy of his expectant friends.
The Lacedaemonians thus placed between two fires, and in the same dilemma, to compare small things with great, as at Thermopylae, where the defenders were cut off through the Persians getting round by the path, being now attacked in front and behind, began to give way, and overcome by the odds against them and exhausted from want of food, retreated.
