For we have been forced to the extremity of having to fight a land-battle on shipboard, and it is manifestly to our interest neither to back water ourselves nor to suffer them to do so, especially since the whole shore, except the small part of it that our land-force holds, is hostile.
"Remembering these things, you must fight to the last with all your strength and not allow yourselves to be driven ashore, but when ship collides with ship be resolved never to separate until you have swept into the sea the hoplites on the enemy's decks.
And these things I urge upon the hoplites not less than upon the sailors, inasmuch as such work belongs rather to those on deck; and, besides, we still have the better of the enemy in most points with our land-force.
