History of the Peloponnesian War

Now the Argives with their wing rushed out ahead of the rest and advanced in some disorder, feeling contempt of the enemy as being Ionians and men who would not await their attack, and so were defeated by the Milesians and not fewer than three hundred of them destroyed.

But the Athenians, after defeating the Peloponnesians first and then driving back the barbarians and the miscellaneous crowd—yet without engaging the Milesians, who after their rout of the Argives had withdrawn into the city, when they saw that the rest of their army was being worsted—finally halted, as being already victorious, close to the city itself.

And it so happened in this battle that on both sides the Ionians were victorious over the Dorians; for the Athenians defeated the Peloponnesians opposed to themselves, and the Milesians the Argives. But the Athenians, after setting up a trophy, made preparations for shutting off the place, which had the shape of an isthmus, with a wall, thinking that, if they should bring Miletus over to their side, the other places would readily come over also.
