History of the Peloponnesian War

The Athenians immediately put to the sword the men forming the first guard, whom they had thus attacked; for they were still in their beds, or only just taking up their arms, the landing having surprised them, as they fancied that the ships were only sailing, according to custom, to their stations for the night.

As soon as it was morning, the rest of the forces also disembarked, viz. all the crews of seventy ships and rather more, (except the lowest rank of rowers,) with their different equipments; eight hundred bowmen, and no less a number of targeteers, the Messenian reinforcements, and all others who were in any positions about Pylus, except the garrison on the fortifications.

By the arrangement of Demosthenes, they were divided into parties of two hundred, more or less, and occupied the highest grounds, that the enemy might be most severely harassed by being surrounded on all sides, and not know where to make resistance, but be annoyed by a double discharge of missiles; being attacked by those behind them, if they charged those before, and by those posted on each side, if they made a flank movement.

And so, wherever they went, they would have the enemy on their rear, light-armed, and the most difficult to deal with, being strong at a distance from the use of arrows, darts, stones, and slings, and it being impossible even to get near them; for they would conquer while flying, and when their enemy retreated, would press them close. It was with such a view of the case that Demosthenes both originally planned the descent, and made his arrangements in the execution of it.
