During this period Prusias also did a thing which deserves to be recorded. The Gauls, whom King Attalus had brought over from Europe to assist him against Achaeus on account of their reputation for courage, had separated from that monarch on account of the jealous suspicions of which I have before spoken, and were plundering the cities on the Hellespont with gross licentiousness and violence, and finally went so far as actually to besiege Ilium. In these circumstances the inhabitants of the Alexandria in the Troad acted with commendable spirit. They sent Themistes with four thousand men and forced the Gauls to raise the siege of Ilium, and drove them entirely out of the Troad, by cutting off their supplies and frustrating all their designs. Thereupon the Gauls seized Arisba, in the territory of Abydos, and thenceforth devoted themselves to forming designs and committing acts of hostility against the cities built in that district. Against them Prusias led out an army; and in a pitched battle put the men to the sword on the field, and slew nearly all their women and children in the camp, leaving the baggage to be plundered by his soldiers. This achievement of Prusias delivered the cities on the Hellespont from great fear and danger, and was a signal warning for future generations against barbarians from Europe being over-ready to cross into Asia. Such was the state of affairs in Greece and Asia. Meanwhile the greater part of Italy had joined the Carthaginians after the battle of Cannae, as I have shown before. I will interrupt my narrative at this point, after having detailed the events in Asia and Greece, embraced by the 140th Olympiad. In my next book after a brief recapitulation of this narrative, I shall fulfil the promise made at the beginning of my work by recurring to the discussion of the Roman constitution.
