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.
