28. The war having been begun with this sufficiently successful expedition, the petty kings and princes, neighbours to the Macedonians, came to the Roman camp; Pleuratus, son of Scerdilaedus, and Amynander, king of the Athamanes, and from the Dardani Bato, son of Longarus. [2] Longarus on his own account had waged war with Demetrius, father of Philip. To their proffers of assistance, the consul [p. 83]replied that he would accept the aid of the Dardani¹ and Pleuratus when he led the army into Macedonia; to Amynander he assigned the task of winning the Aetolians² over for the war. [3] To the ambassadors of Attalus —for they too had arrived at this time —he gave instructions that the king should await the Roman fleet at Aegina, where he was wintering, and uniting with it should continue as before the naval warfare on Philip. [4] Ambassadors were sent to the Rhodians also, that they should take up their share in the war. Nor did Philip —for he had by now reached Macedonia —carry on less vigorously his preparations for the war. [5] He sent his son Perseus, who was still a boy, with guardians from among his friends to guide his youth, with part of the troops to hold the passes which lead to Pelagonia. [6] He destroyed Sciathus and Peparethus, cities not unknown to fame, to prevent their becoming prize and prey to the fleet of the enemy. He sent ambassadors to the Aetolians, lest that restless people should, on the arrival of the Romans, change its allegiance.
