The Aetolian disaster, which had been mainly caused by the wood, had not a little to do with these reflections. Meanwhile, one of the soldiers who were compelled by want of room to land on the extremities of the island and take their dinners, with outposts fixed to prevent a surprise, set fire to a little of the wood without meaning to do so;and as it came on to blow soon afterwards, almost the whole was consumed before they were aware of it. Demosthenes was now able for the first time to see how numerous the Lacedaemonians really were, having up to this moment been under the impression that they took in provisions for a smaller number; he also saw that the Athenians thought success important and were anxious about it, and that it was now easier to land on the island, and accordingly got ready for the attempt, sent for troops from the allies in the neighbourhood, and pushed forward his other preparations. At this moment Cleon arrived at Pylos with the troops which he had asked for, having sent on word to say that he was coming. The first step taken by the two generals after their meeting was to send a herald to the camp on the mainland, to ask if they were disposed to avoid all risk and to order the men on the island to surrender themselves and their arms, to be kept in gentle custody until some general convention should be concluded.
On the rejection of this proposition the generals let one day pass, and the next, embarking all their heavy infantry on board a few ships, put out by night, and a little before dawn landed on both sides of the island from the open sea and from the harbour, being about eight hundred strong, and advanced with a run against the first post in the island.
The enemy had distributed his force as follows: In this first post there were about thirty heavy infantry; the centre and most level part, where the water was, was held by the main body, and by Epitadas their commander; while a small party guarded the very end of the island, towards Pylos, which was precipitous on the sea-side and very difficult to attack from the land, and where there was also a sort of old fort of stones rudely put together, which they thought might be useful to them, in case they should be forced to retreat.
Such was their disposition.
The advanced post thus attacked by the Athenians was at once put to the sword, the men being scarcely out of bed and still arming, the landing having taken them by surprise, as they fancied the ships were only sailing as usual to their stations for the night. As soon as day broke, the rest of the army landed, that is to say, all the crews of rather more than seventy ships, except the lowest rank of oars, with the arms they carried, eight hundred archers, and as many targeteers, the Messenian reinforcements, and all the other troops on duty round Pylos, except the garrison on the fort. The tactics of Demosthenes had divided them into companies of two hundred, more or less, and made them occupy the highest points in order to paralyse the enemy by surrounding him on every side and thus leaving him without any tangible adversary, exposed to the cross-fire of their host; plied by those in his rear if he attacked in front, and by those on one flank if he moved against those on the other. In short, wherever he went he would have the assailants behind him, and these light-armed assailants, the most awkward of all; arrows, darts, stones, and slings ****** them formidable at a distance, and there being no means of getting at them at close quarters, as they could conquer flying, and the moment their pursuer turned they were upon him. Such was the idea that inspired Demosthenes in his conception of the descent, and presided over its execution.
Meanwhile the main body of the troops in the island (that under Epitadas), seeing their outpost cut off and an army advancing against them, serried their ranks and pressed forward to close with the Athenian heavy infantry in front of them, the light troops being upon their flanks and rear. However, they were not able to engage or to profit by their superior skill, the light troops keeping them in check on either side with their missiles, and the heavy infantry remaining stationary instead of advancing to meet them; and although they routed the light troops wherever they ran up and approached too closely, yet they retreated fighting, being lightly equipped, and easily getting the start in their flight, from the difficult and rugged nature of the ground, in an island hitherto desert, over which the Lacedaemonians could not pursue them with their heavy armour.
