History of the Peloponnesian War

and at the same time I call on you, Athenians as you are, and knowing from experience as you do the nature of a naval descent on the coast of others, namely, that if a man should stand his ground, and not retreat for fear of the roaring surf and the terrors of the ships sailing to shore, he would never be driven back; [I call on you, I say,] now in your own case to stand your ground, and by resisting them along the very beach to save both yourselves and the place.

When Demosthenes had thus encouraged them, they were more inspirited, and went down against them, and ranged themselves close along the sea.

The Lacedaemonians, moved from their position, and assaulted the fort at the same time both with their army by land and with their ships, of which there were forty-three; the admiral on board being Thrasymelidas son of Cratesicles, a Spartan. And he assaulted it just where Demosthenes was expecting him.

So the Athenians defended themselves on both sides, landward and seaward; while their opponents, divided into detachments of a few ships, because it was not possible for more to bring to, and relieving each other in turn, were sailing up against them with all eagerness and mutual exhortation, if by any means they might force their passage and take the place.
