In Caria, no doubt, Stratonicea was reduced by force of arms; but Magnesia on the Sipylus successfully withstood a severe siege, in which Mithradates' ablest officer Archelaus was defeated and wounded.

Rhodes, the asylum of the Romans who had escaped from Asia with the governor Lucius Cassius among them, was assailed on the part of Mithradates by sea and land with immense superiority of force.
But his sailors, courageously as they did their duty under the eyes of the king, were awkward novices, and so Rhodian squadrons vanquished those of Pontus four times as strong and returned home with captured vessels.

By land also the siege made no progress; after a part of the works had been destroyed, Mithradates abandoned the enterprise, and the important island as well as the mainland opposite remained in the hands of the Romans.
Pontic Invasion of Europe Predatory Inroads of the Thracians Thrace and Macedonia Occupied by the Pontic Armies Pontic Fleet in the Aegean But not only was the Asiatic province occupied by Mithradates almost without defending itself, chiefly in consequence of the Sulpician revolution breaking out at a most unfavourable time; Mithradates even directed an attack against Europe.

Already since 662 the neighbours of Macedonia on her northern and eastern frontier had been renewing their incursions with remarkable vehemence and perseverance; in the years 664, 665 the Thracians overran Macedonia and all Epirus and plundered the temple of Dodona.

Still more singular was the circumstance, that with these movements was combined a renewed attempt to place a pretender on the Macedonian throne in the person of one Euphenes.
