History of the Peloponnesian War

Advancing from Doberus, the Thracian host first invaded what had been once Philip's government, and took Idomene by assault, Gortynia, Atalanta, and some other places by negotiation, these last coming over for love of Philip's son, Amyntas, then with Sitalces. Laying siege to Europus, and failing to take it,

he next advanced into the rest of Macedonia to the left of Pella and Cyrrhus, not proceeding beyond this into Bottia and Pieria, but staying to lay waste Mygdonia, Crestonia, and Anthemus.

The Macedonians never even thought of meeting him with infantry; but the Thracian host was, as opportunity offered, attacked by handfuls of their horse, which had been reinforced from their allies in the interior. Armed with cuirasses, and excellent horsemen, wherever these charged they overthrew all before them, but ran considerable risk in entangling themselves in the masses of the enemy, and so finally desisted from these efforts, deciding that they were not strong enough to venture against numbers so superior.

Meanwhile Sitacles opened negotiations with Perdiccas on the objects of his expedition; and finding that the Athenians, not believing that he would come, did not appear with their fleet, though they sent presents and envoys, despatched a large part of his army against the Chalcidians and Bottiaeans, and cutting them up inside their walls laid waste their country.
