History of the Peloponnesian War

By this accident, Demosthenes, the better discerning that the Lacedaemonians were more than he had imagined, having before, by victual sent unto them, thought them not so many, did now prepare himself for the enterprise as a matter deserving the Athenians' utmost care and as having better commodity of landing in the island than before he had, and both sent for the forces of such confederates as were near and put in readiness every other needful thing.

And Cleon, who had sent a messenger before to signify his coming, came himself also, with those forces which he had required, unto Pylus. When they were both together, first they sent a herald to the camp in the continent to know if they would command those in the island to deliver up themselves and their arms without battle, to be held with easy imprisonment till some agreement were made touching the main war.

Which when they refused, the Athenians for one day held their hands; but the next day, having put aboard upon a few galleys all their men of arms, they put off in the night and landed a little before day on both sides of the island, both from the main and from the haven, to the number of about eight hundred men of arms, and marched upon high speed towards the foremost watch of the island.

For thus the Lacedaemonians lay quartered. In this foremost watch were about thirty men of arms; the middest and evenest part of the island and about the water was kept by Epitadas, their captain, with the greatest part of the whole number; and another part of them, which were not many, kept the last guard towards Pylus, which place to the seaward was on a cliff and least assailable by land. For there was also a certain fort which was old and made of chosen [not of hewn] stones, which they thought would stand them in stead in case of violent retreat. Thus they were quartered.
