History of the Peloponnesian War

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.
