History of the Peloponnesian War

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.
