History of the Peloponnesian War

And just the wing of Aristeus, and such picked troops of the Corinthians and the rest as were around him, routed the wing opposed to them, and advanced in pursuit a considerable distance; but the remaining force of the Potidaeans and Peloponnesians was beaten by the Athenians, and fled within the wall for refuge.

When Aristeus was returning from the pursuit, seeing the rest of the army conquered, he was at a loss which place he should risk going to, whether towards Olynthus, or to Potidaea. He determined, however, to draw his men into as small a space as possible, and at a running pace force his way into Potidaea: and he passed along the breakwater through the sea, annoyed by missiles [from the Athenian slips], and with difficulty; having lost a few men, but saved the rest.

Now the auxiliaries of the Potidaeans from Olynthus, (the town is about sixty stades off, and within sight,) when the battle was beginning, and the signals had been hoisted, advanced a short distance to give succour, and the Macedonian horse drew up against them to prevent it; but when the victory soon declared for the Athenians, and the signals had been taken down, they retired again within the wall, and the Macedonians to the Athenians. So neither side had any cavalry present [in the engagement].

After the battle the Athenians erected a trophy, and gave back their dead to the Potidaeans under truce. There were killed of the Potidaeans and their allies a little less than three hundred, and of the Athenians themselves one hundred and fifty, and Callias their general.

Now against the wall on [*]( Literally, having walled off, i.e. cut off by a transverse wall from communication with the country. The absence of any such wall on the opposite side of the city is afterwards expressed by τὴν παλλήνην ἀτείχιστον οὖσαν.) the side of the isthmus the Athenians immediately raised works, and manned them. But that towards Pallene had no works raised against it; for they did not think themselves strong enough both to keep a garrison on the isthmus, and to cross over to Pallene and raise works there; fearing that the Potidaeans and their allies might attack them when divided.
