The Athenian fleet was now suddenly withdrawn in order to prevent an intended movement in Kamarina, where a philo-Syracusan party under Archias threatened revolt: and the Messenian forces, thus left free, invaded the territory of their neighbor, the Chalkidic city of Naxos, sending their fleet round to the mouth of the Akesinês near that city. They were ravaging the lands, and were preparing to storm the town, when a considerable body of the indigenous Sikels were seen descending the neighboring hills to succor the Naxians: upon which the latter, elate with the sight, and mistaking the new comers for their Grecian brethren from Leontini, rushed out of the gates and made a vigorous sally at a moment when their enemies were unprepared. The Messenians were completely defeated, with the loss of no less than one thousand men, and with a still greater loss sustained in their retreat home from the pursuit of the Sikels. Their fleet went back also to Messênê, from whence such of the ships as were not Messenian returned home. So much was the city weakened by its recent defeat, that a Lokrian garrison was sent for its protection under Demomelês, while the Leontines and Naxians, together with the Athenian squadron on returning from Kamarina, attacked it by land and sea in this moment of distress. A well-timed sally of the Messenians and Lokrians, however, dispersed the Leontine land-force; but the Athenian force, landing from their ships, attacked the assailants while in the disorder of pursuit, and drove them back within the walls. The scheme against Messênê, however, had now become impracticable, so that the Athenians crossed the strait to Rhegium.[203] [203] Thucyd. iv, 25.
