History of the Peloponnesian War

There had crossed over in all four hundred and twenty heavy-armed, two hundred and ninety-two of which were taken [to Athens] alive, and the rest were slain. Of those that were living about one hundred and twenty were Spartans. On the side of the Athenians there were not many killed; for the battle was not fought hand to hand.

The whole length of time that the men were blockaded, from the sea-fight to the battle in the island, was seventy-two days; for about twenty of which, whilst the ambassadors were gone to treat of peace, they had provisions given;

but for the remainder, they were fed by those that sailed in by stealth. And there was still corn in the island, and other kinds of food were found in it; for Epitadas, the commander, supplied them with it more sparingly than he might have done.
