Perdiccas, at once uniting the soldiers of Brasidas with his own forces, made war upon Arrhibaeus1
the son of Bromerus, king of the Lyncestians, a neighboring people of Macedonia; for he had a quarrel with him and wanted to subdue him.
But when he and Brasidas and the army arrived at the pass leading into Lyncus, Brasidas said that before appealing to arms he should like to try in person the effect of negotiations, and see if he could not make Arrhibaeus an ally of the Lacedaemonians.
He was partly influenced by messages which came from Arrhibaeus expressing his willingness to submit any matter in dispute to the arbitration of Brasidas: and the Chalcidian ambassadors who accompanied the expedition recommended him not to remove from Perdiccas' path all his difficulties, lest, when they were wanting him for their own affairs, his ardour should cool.
Besides, the envoys of Perdiccas when at Sparta had said something to the Lacedaemonians about his making many of the neighbouring tribes their allies, and on this ground Brasidas claimed to act jointly with Perdiccas in the matter of Arrhibaeus.
But Perdiccas answered that he had not brought Brasidas there to arbitrate in the quarrels of Macedonia; he had meant him to destroy his enemies when he pointed them out. While he, Perdiccas, was maintaining half the Lacedaemonian army, Brasidas had no business to be holding parley with Arrhibaeus.
But in spite of the opposition and resentment of Perdiccas, Brasidas communicated with Arrhibaeus, and was induced by his words to withdraw his army without invading the country. From that time Perdiccas thought himself ill-used, and paid only a third instead of half the expenses of the army.
