Besides, the envoys of Perdiccas had talked at Lacedaemon about his bringing many of the places round him into alliance with them; and thus Brasidas thought he might take a larger view of the question of Arrhabaeus.

Perdiccas however retorted that he had not brought him with him to arbitrate in their quarrel, but to put down the enemies whom he might point out to him; and that while he, Perdiccas, maintained half his army it was a breach of faith for Brasidas to parley with Arrhabaeus.

Nevertheless Brasidas disregarded the wishes of Perdiccas and held the parley in spite of him, and suffered himself to be persuaded to lead off the army without invading the country of Arrhabaeus; after which Perdiccas, holding that faith had not been kept with him, contributed only a third instead of half of the support of the army.
