History of the Peloponnesian War

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 paralyze 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 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.

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.
