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 seaside 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 crossfire 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 making 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.
