History of the Peloponnesian War

The same summer, and at the same time as the expedition was made against the Plataeans, the Athenians marched with two thousand heavy-armed of their own, and two hundred horse, against the Thrace-ward Chalcidians, and the Bottiaeans, when the corn was ripe, under the command of Xenophon son of Euripides, and two colleagues.

On arriving under the walls of Spartolus in Bottiaea, they destroyed the corn; and expected that the town would also surrender to them, through the intrigues of a party within. Those, however, who did not wish this, having sent to Olynthus, a body of heavy-armed and other troops came as a garrison for the place;

and on their making a sally from it, the Athenians met them in battle close to the town. The heavy-armed of the Chalcidians, and some auxiliaries with them, were defeated by the Athenians, and retired into Spartolus; but the Chalcidian horse and light-armed defeated the horse and light-armed of the Athenians.

They had [from the first] some few targeteers from the district of Crusis, as it is called; and when the battle had just been fought, others joined them from Olynthus.
