Meanwhile, when day came and the Syracusans and allies found that the Athenians were gone, most of them accused Gylippus of having let them escape on purpose, and hastily pursuing by the road which they had no difficulty in finding that they had taken, overtook them about dinner-time. They first came up with the troops under Demosthenes, who were behind and marching somewhat slowly and in disorder, owing to the night panic above referred to, and at once attacked and engaged them, the Syracusan horse surrounding them with more ease now that they were separated from the rest and hemming them in on one spot. The division of Nicias was five or six miles on in front, as he led them more rapidly, thinking that under the circumstances their safety lay not in staying and fighting, unless obliged, but in retreating as fast as possible, and only fighting when forced to do so. On the other hand, Demosthenes was, generally speaking, harassed more incessantly, as his post in the rear left him the first exposed to the attacks of the enemy; and now, finding that the Syracusans were in pursuit, he omitted to push on, in order to form his men for battle, and so lingered until he was surrounded by his pursuers and himself and the Athenians with him placed in the most distressing position, being huddled into an enclosure with a wall all round it, a road on this side and on that, and olive-trees in great number, where missiles were showered in upon them from every quarter. This mode of attack the Syracusans had with good reason adopted in preference to fighting at close quarters, as to risk a struggle with desperate men was now more for the advantage of the Athenians than for their own; besides, their success had now become so certain that they began to spare themselves a little in order not to be cut off in the moment of victory, thinking too that, as it was, they would be able in this way to subdue and capture the enemy.
In fact, after plying the Athenians and allies all day long from every side with missiles, they at length saw that they were worn out with their wounds and other sufferings; and Gylippus and the Syracusans and their allies made a proclamation, offering their liberty to any of the islanders who chose to come over to them; and some few cities went over. Afterwards a capitulation was agreed upon for all the rest with Demosthenes, to lay down their arms on condition that no one was to be put to death either by violence or imprisonment or want of the necessaries of life. Upon this they surrendered to the number of six thousand in all, laying down all the money in their possession, which filled the hollows of four shields, and were immediately conveyed by the Syracusans to the town.
Meanwhile Nicias with his division arrived that day at the river Erineus, crossed over, and posted his army upon some high ground upon the other side. The next day the Syracusans overtook him and told him that the troops under Demosthenes had surrendered, and invited him to follow their example. Incredulous of the fact, Nicias asked for a truce to send a horseman to see, and upon the return of the messenger with the tidings that they had surrendered, sent a herald to Gylippus and the Syracusans, saying that he was ready to agree with them on behalf of the Athenians to repay whatever money the Syracusans had spent upon the war if they would let his army go; and offered until the money was paid to give Athenians as hostages, one for every talent. The Syracusans and Gylippus rejected this proposition, and attacked this division as they had the other, standing all round and plying them with missiles until the evening. Food and necessaries were as miserably wanting to the troops of Nicias as they had been to their comrades; nevertheless they watched for the quiet of the night to resume their march. But as they were taking up their arms the Syracusans perceived it and raised their paean, upon which the Athenians, finding that they were discovered, laid them down again, except about three hundred men who forced their way through the guards and went on during the night as they were able.
As soon as it was day Nicias put his army in motion, pressed, as before, by the Syracusans and their allies, pelted from every side by their missiles, and struck down by their javelins. The Athenians pushed on for the Assinarus, impelled by the attacks made upon them from every side by a numerous cavalry and the swarm of other arms, fancying that they should breathe more freely if once across the river, and driven on also by their exhaustion and craving for water.
