The Athenians now fell into great disorder and perplexity, so that it was not easy to get from one side or the other any detailed account of the affair. By day certainly the combatants have a clearer notion, though even then by no means of all that takes place, no one knowing much of anything that does not go on in his own immediate neighbourhood; but in a night engagement (and this was the only one that occurred between great armies during the war) how could any one know anything for certain? Although there was a bright moon they saw each other only as men do by moonlight, that is to say, they could distinguish the form of the body, but could not tell for certain whether it was a friend or an enemy. Both had great numbers of heavy infantry moving about in a small space. Some of the Athenians were already defeated, while others were coming up yet unconquered for their first attack. A large part also of the rest of their forces either had only just got up, or were still ascending, so that they did not know which way to march. Owing to the rout that had taken place all in front was now in confusion, and the noise made it difficult to distinguish anything. The victorious Syracusans and allies were cheering each other on with loud cries, by night the only possible means of communication, and meanwhile receiving all who came against them; while the Athenians were seeking for one another, taking all in front of them for enemies, even although they might be some of their now flying friends; and by constantly asking for the watchword, which was their only means of recognition, not only caused great confusion among themselves by asking all at once, but also made it known to the enemy, whose own they did not so readily discover, as the Syracusans were victorious and not scattered, and thus less easily mistaken. The result was that if the Athenians fell in with a party of the enemy that was weaker than they, it escaped them through knowing their watchword; while if they themselves failed to answer they were put to the sword. But what hurt them as much, or indeed more than anything else, was the singing of the paean, from the perplexity which it caused by being nearly the same on either side; the Argives and Corcyraeans and any other Dorian peoples in the army, struck terror into the Athenians whenever they raised their paean, no less than did the enemy. Thus, after being once thrown into disorder, they ended by coming into collision with each other in many parts of the field, friends with friends, and citizens with citizens, and not only terrified one another, but even came to blows and could only be parted with difficulty. In the pursuit many perished by throwing themselves down the cliffs, the way down from Epipolae being narrow; and of those who got down safely into the plain, although many, especially those who belonged to the first armament, escaped through their better acquaintance with the locality, some of the newcomers lost their way and wandered over the country, and were cut off in the morning by the Syracusan cavalry and killed.
The next day the Syracusans set up two trophies, one upon Epipolae where the ascent had been made, and the other on the spot where the first check was given by the Boeotians; and the Athenians took back their dead under truce. A great many of the Athenians and allies were killed, although still more arms were taken than could be accounted for by the number of the dead, as some of those who were obliged to leap down from the cliffs without their shields escaped with their lives and did not perish like the rest.
After this the Syracusans, recovering their old confidence at such an unexpected stroke of good fortune, dispatched Sicanus with fifteen ships to Agrigentum where there was a revolution, to induce if possible the city to join them; while Gylippus again went by land into the rest of Sicily to bring up reinforcements, being now in hope of taking the Athenian lines by storm, after the result of the affair on Epipolae.
