Book 2
They possessed besides a certain narrow portion of Paeonia near unto the river Axius reaching from above down to Pella and to the sea. Beyond Axius they possess the country called Mygdonia as far as to Strymon, from whence they have driven out the Edonians.
Furthermore, they drave the Eordians out of the territory now called Eordia (of whom the greatest part perished, but there dwell a few of them yet about Physca) and the Almopians out of Almopia.
The same Macedonians subdued also other nations and hold them yet, as Anthemus, Crestonia, and Bisaltia, and a great part of the Macedonians themselves. But the whole is called Macedonia and was the kingdom of Perdiccas the son of Alexander when Sitalces came to invade it.
The Macedonians, unable to stand in the field against so huge an army, retired all within their strongholds and walled towns, as many as the country afforded,
which were not many then, but were built afterwards by Archelaus the son of Perdiccas when he came to the kingdom, who then also laid out the highways straight and took order both for matter of war, as horses and arms and for other provision, better than all the other eight kings that were before him. The Thracian army, arising from Doberus, invaded that territory first which had been the principality of Philip and took Eidomene by force;
but Gortynia, Atalanta, and some other towns he had yielded to him for the love of Amyntas the son of Philip, who was then in the army. They also assaulted Europus but could not take it. Then they went on further into Macedonia on the part that lies on the right hand of Pella and Cyrrhus;
but within these into Bottiaea and Pieria they entered not but wasted Mygdonia, Crestonia, and Anthemus. Now the Macedonians had never any intention to make head against them with their foot;
but sending out their horsemen, which they had procured from their allies of the higher Macedonia, they assaulted the Thracian army in such places where, few against many, they thought they might do it with most convenience. And where they charged, none was able to resist them, being both good horsemen and well armed with breastplates; but enclosed by the multitude of the enemies, they fought against manifest odds of number so that in the end they gave it over, esteeming themselves too weak to hazard battle against so many.
After this Sitalces gave way to a conference with Perdiccas touching the motives of this war. And forasmuch as the Athenians were not arrived with their fleet (for they thought not that Sitalces would have made the journey, but had sent ambassadors to him with presents), he sent a part of his army against the Chalcideans and Bottiaeans, wherewith, having compelled them within their walled towns, he wasted and destroyed their territory.
Whilst he stayed in these parts, the Thessalians southward, and the Magnetians, and the rest of the nations subject to the Thessalians, and all the Grecians as far as to Thermopylae were afraid he would have turned his forces upon them and stood upon their guard.
And northward, those Thracians that inhabit the champaign country beyond Strymon, namely the Panaeans, Odomantians, Droans, and Dersaeans, all of them free states, were afraid of the same.
He gave occasion also to a rumour that he meant to lead his army against all those Grecians that were enemies to the Athenians, as called in by them to that purpose by virtue of their league.
But whilst he stayed, he wasted the Chalcidean, Bottiaean, and Macedonian territories; and when he could not effect what he came for and his army both wanted victual and was afflicted with the coldness of the season, Seuthes the son of Spardocus, his cousin-german and of greatest authority next himself, persuaded him to make haste away. Now Perdiccas had dealt secretly with Seuthes and promised him his sister in marriage and money with her;
and Sitalces at the persuasion of him after the stay of full thirty days, whereof he spent eight in Chalcidea, retired with his army with all speed into his own kingdom. And Perdiccas shortly after gave to Seuthes his sister Stratonica in marriage, as he had promised. This was the issue of this expedition of Sitalces.
The same winter, after the fleet of the Peloponnesians was dissolved, the Athenians that were at Naupactus under the conduct of Phormio sailed along the coast to Astacus and, disbarking, marched into the inner parts of Acarnania. He had in his army four hundred men of arms that he brought with him in his galleys and four hundred more Messenians. With these he put out of Stratus, Coronta, and other places all those whose fidelity he thought doubtful. And when he had restored Cynes the son of Theolytus to Coronta, they returned again to their galleys.
For they thought they should not be able to make war against the Oeniades (who only of all Acarnania are the Athenians' enemies) in respect of the winter. For the river Achelöus, springing out of the mountain Pindus and running through Dolopia, and through the territories of the Agraeans and the Amphilochians, and through most part of the champaign of Acarnania, passing above by the city of Stratus, and falling into the sea by the city of the Oeniades, which also it moateth about with fens, by the abundance of water maketh it hard lying there for an army in time of winter.
Also most of the islands Echinades lie just over against Oenia, hard by the mouth of Achelöus. And the river, being a great one, continually heapeth together the gravel, insomuch that some of those islands are become continent already; and the like in short time is expected by the rest.
For not only the stream of the river is swift, broad, and turbidous, but also the islands themselves stand thick, and, because the gravel cannot pass, are joined one to another, lying in and out, not in a direct line nor so much as to give the water his course directly forward into the sea. These islands are all desert and but small ones.
It is reported that Apollo by his oracle did assign this place for an habitation to Alcmaeon the son of Amphiareus, at such time as he wandered up and down for the killing of his mother, telling him that he should never be free from the terrors that haunted him till he had found out and seated himself in such a land as when he slew his mother, the sun had never seen nor was then land because all other lands were polluted by him. Hereupon being at a nonplus, as they say, with much ado he observed this ground congested by the river Achelöus and thought there was enough cast up to serve his turn already since the time of the slaughter of his mother, after which it was now a long time that he had been a wanderer.
Therefore, seating himself in the places about the Oeniades, he reigned there and named the country after the name of his son Acarnas. Thus goes the report, as we have heard it concerning Alcmaeon.
But Phormio and the Athenians, leaving Acarnania and returning to Naupactus, in the very beginning of the spring came back to Athens and brought with them such galleys as they had taken and the freemen they had taken prisoners in their fights at sea, who were again set at liberty by exchange of man for man.
So ended that winter, and the third year of the war written by Thucydides.
