History of the Peloponnesian War

Besides, the ministers of Perdiccas, when they were at Lacedaemon, had spoken there as if they had meant to bring [as] many of the places about him [as they could] into the Lacedaemonian league. So that Brasidas favoured Arrhibaeus for the public good of their own state.

But Perdiccas said that he brought not Brasidas thither to be a judge of his controversies, but to destroy those enemies which he should show him; and that it will be an injury, seeing he pays the half of his army, for Brasidas to parley with Arrhibaeus.

Nevertheless Brasidas, whether Perdiccas would or not, and though it made a quarrel, had conference with Arrhibaeus, by whom also he was induced to withdraw his army. But from that time forward Perdiccas, instead of half, paid but a third part of his army, as conceiving himself to have been injured.

The same summer, a little before the vintage, Brasidas, having joined to his own the forces of the Chalcideans, marched to Acanthus, a colony of the Andrians.

And there arose sedition about receiving him between such as had joined with the Chalcideans in calling him thither and the common people. Nevertheless, for fear of their fruits, which were not yet gotten in, the multitude was won by Brasidas to let him enter alone, and then, after he had said his mind, to advise what to do amongst themselves. And presenting himself before the multitude (for he was not uneloquent, though a Lacedaemonian), he spake to this effect:

"Men of Acanthus, the reason why the Lacedaemonians have sent me and this army abroad is to make good what we gave out in the beginning for the cause of our war against the Athenians, which was that we meant to make a war for the liberties of Greece.
