This was the first conflict and treaty between the Romans and the Illyrians. Thereupon the Romans made Corcyra and Apollonia free. To Demetrius they gave certain castles as a reward for his treason to his own people, adding the express condition that they gave them only conditionally, for they suspected the man's bad faith; and
before long he began to show it. While the Romans were
engaged in a three years' war with the Gauls on the river Po, Demetrius, thinking that they had their hands full, set forth on a piratical expedition, brought the Istrians, another Illyrian tribe, into the enterprise, and detached the Atintani from Rome. The Romans, when they had settled their business with the Gauls, immediately sent a naval force and overpowered the pirates. The following year they marched against Demetrius and his Illyrian fellow-culprits. Demetrius fled to Philip, king of Macedon, but when he returned and resumed his piratical career in the Adriatic they slew him and utterly demolished his native town of Pharus,
which was associated with him in crime. They spared the
Illyrians on account of Pinnes, who again besought them to do so. And such was the second conflict and treaty between them and the Illyrians.
