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.
The Athenians were already masters of the approaches when Cleon and Demosthenes perceiving that, if the enemy gave way a single step further, they would be destroyed by their soldiery, put a stop to the battle and held their men back; wishing to take the Lacedaemonians alive to Athens, and hoping that their stubbornness might relax on hearing the offer of terms, and that they might surrender and yield to the present overwhelming danger.
