History of the Peloponnesian War

Thus it happened that Demosthenes, who could now get a better view of the Lacedaemonians, found that they were more numerous than he had thought; for he had previously suspected that the number for which they were sending provisions was smaller than they stated.[*](cf. 4.16.1.) He also found that the island was less difficult to make a landing upon than he had supposed.

He now, therefore, believing that the object in view was well worth a more serious effort on the part of the Athenians, began preparations for the attempt, summoning troops from the allies in the neighbourhood and getting everything else ready. Cleon, meanwhile, having first sent word to Demosthenes that he would soon be there, arrived at Pylos, bringing the army for which he had asked. As soon as they had joined forces, they sent a herald to the enemy's camp on the mainland, giving them the option, if they wished to avoid a conflict, of ordering the men on the island to surrender themselves and their arms, on condition that they should be held in mild custody until some agreement should be reached about the main question.[*](ie. a general peace.)
