History of the Peloponnesian War

But Perdiccas immediately took Brasidas and his army, together with his own forces, and made an expedition against his neighbour Arrhabaeus, son of Bromerus, king of the Lyncestian Macedonians; for he had a quarrel with him and wished to subdue him.

But when he and Brasidas arrived with their combined armies at the pass leading to Lyncus, Brasidas said that he wished, before appealing to arms, to have a conference with Arrhabaeus and make him an ally of the Lacedaemonians, if he could.

For it seemed that Arrhabaeus had made some overtures and was ready to submit the question at issue to Brasidas' arbitration; the Chalcidian envoys who were present also kept urging him not to remove the difficulties from the path of Perdiccas, since they wished to have in him a more zealous helper in their own affairs.

Furthermore, the envoys of Perdiccas, when they were at Lacedaemon, had given a hint to the effect that he would bring many of the places in his neighbourhood into alliance with the Lacedaemonians; consequently Brasidas was inclined to insist upon having a freer hand in dealing with Arrhabaeus.

But Perdiccas said that he had not brought Brasidas to be a judge of their quarrels, but rather to be a destroyer of any enemies whom he himself might designate, and that Brasidas would do wrong if, when he himself maintained half the army, he should parley with Arrhabaeus.

But Brasidas, in spite of Perdiccas and after a quarrel with him, held the conference, and finding the king's arguments convincing, withdrew his army without invading his country. After this Perdiccas contributed only a third instead of one-half of the maintenance, considering himself to be aggrieved.
