History of the Peloponnesian War

On the first day he took Potidanea; on the second, Crocyleum; and on the third, Tichium, where he halted, and sent off his booty to Eupalium in Locris: for he intended, when he had subdued the other parts, to make a subsequent expedition against the Ophionians, if they would not surrender, after returning to Naupactus.

But the Aetolians were both aware or these preparations when he first formed his designs against them, and when the army had invaded their country they came to the rescue with a great force, all of them, so that even the most distant of the Ophionians, who stretch towards the Melian Gulf, the Borniensians and Calliensians, joined in bringing aid.

Now the Messenians gave Demosthenes the following advice, as they also did at first. Assuring him that the reduction of the Aetolians was easy, they urged him to go as quickly as possible against their villages, and not wait till the whole people should unite and oppose him, but to endeavour successively to make himself master of each village [*]( Or, as it came in his way. Literally, at his feet. Compare He rodotus, 3. 79, πάντα τινὰ τῶν μάγων τὸν ἐν ποσὶ γινόμενον.) before him.

Being thus persuaded by them, and relying on his fortune, because nothing ever went against him, without waiting for those who should have reinforced him (for he was most in want of light-armed dartmen) he advanced for Aegitium, and took it by assault, the inhabitants flying before him, and posting themselves on the hills round the town; for it stood on high ground, at the distance of about eighty stades from the sea.

The Aetolians (for they had now come to the rescue of Aegitium) charged the Athenians and their allies, running down from the hills in different directions, and plied them with darts; retreating when the Athenian force advanced against them, and pressing it close when it retired. And for a long time this was the character of the engagement—repeated pursuing and retreating—in both of which the Athenians had the worse.
