In the meantime, Figulus sailed from Heracleum to Thessalonica. He pillaged the countryside and repulsed sorties from the towns, employing naval catapults. After this, the troops were re-embarked, and he made for Aenia, fifteen miles away, and pillaged its fertile countryside. He then sailed to Antigonea and did the same, but a Macedonian detachment intercepted the troops and killed 500 men. There was another fight by the coast and, assisted by men from the ships, the Romans killed 200 enemies. The fleet sailed on to the district of Pallene (the Chalkidiki peninsula), whose territory by far the most plentiful. There, Figulus was joined by 20 ships from Eumenes II of Pergamon and five ships from Prusias I of Bithynia. This encouraged him to besiege Cassandrea, which connected the Pallene peninsula (one of the three long peninsulas which extend from the Chalkidiki peninsula) with the rest of the land. An attack was repulsed by the city garrison. The arrival of a Macedonian ship from Thessalonica with Gallic auxiliaries led to the lifting of the siege. The Romans and Eumenes considered besieging Torone, but changed their minds because it had a strong garrison. They went on to Demetrias, but they saw that the walls were fully manned. Thus, they brought the fleet into harbour at Iolcos, pillaging the countryside there first.
