Arbitration, however, was what the Athenians did not choose to risk; being determined to send troops at once to the place, and furious at the idea of even the islanders now daring to revolt, in a vain reliance upon the power of the Lacedaemonians by land.
Besides the facts of the revolt were rather as the Athenians contended, the Scionaeans having revolted two days after the convention.

Cleon accordingly succeeded in carrying a decree to reduce and put to death the Scionaeans; and the Athenians employed the leisure which they now enjoyed in preparing for the expedition.
Meanwhile Mende revolted, a town in Pallene and a colony of the Eretrians, and was received without scruple by Brasidas, in spite of its having evidently come over during the armistice, on account of certain infringements of the truce alleged by him against the Athenians.

This audacity of Mende was partly caused by seeing Brasidas forward in the matter and by the conclusions drawn from his refusal to betray Scione; and besides, the conspirators in Mende were few, and, as I have already intimated, had carried on their practices too long not to fear detection for themselves, and not to wish to force the inclination of the multitude.

This news made the Athenians more furious than ever, and they at once prepared against both towns.

Brasidas, expecting their arrival, conveyed away to Olynthus in Chalcidice the women and children of the Scionaeans and Mendaeans, and sent over to them five hundred Peloponnesian heavy infantry and three hundred Chalcidian targeteers, all under the command of Polydamidas.
Leaving these two towns to prepare together against the speedy arrival of the Athenians, Brasidas and Perdiccas started on a second joint expedition into Lyncus against Arrhabaeus; the latter with the forces of his Macedonian subjects, and a corps of heavy infantry composed of Hellenes domiciled in the country; the former with the Peloponnesians whom he still had with him and the Chalcidians, Acanthians, and the rest in such force as they were able.
