History of the Peloponnesian War

The Argives, advancing from the line with their own wing, and despising the enemy, while they pushed forward in some disorder, as against Ionians and men who would not receive their charge, were defeated by the Milesians, and not less than three hundred of them slain.

But the Athenians defeated the Peloponnesians first, then beat back the barbarians and the rest of the multitude, and without engaging the Milesians, (for they retreated into their city after their rout of the Argives, on seeing the rest of their army worsted,) they pitched their camp, as being now victorious, close to the very city of Miletus.

And it so happened, that in this battle the Ionians on both sides were superior to the Dorians; for the Athenians conquered the Peloponnesians opposed to them, and the Milesians the Argives. After erecting a trophy, the Athenians prepared to invest the place, (which stood on an isthmus,) thinking that if they could win Miletus, the other towns would easily come over to them.
