When Sulla returned to Italy after the First Mithridatic War, he left L. Murena, with two legions, to hold the command in Asia. Murena, who was eager for some opportunity of earning the honor of a triumph, pretending that Mithridates had not yet evacuated the whole of Cappadocia, not only marched into that country, but even crossed the Halys, and laid waste the plains of Pontus itself (B.C. 83). To this flagrant breach of the treaty so lately concluded the Roman general was in great measure instigated by Archelaus, who, finding himself regarded with suspicion by Mithridates, had consulted his safety by flight, and was received with the utmost honors by the Romans. Mithridates, who was wholly unprepared to renew the contest with Rome, offered no opposition to the progress of Murena; but finding that general disregard his remonstrances, he sent to Rome to complain of his aggression. When, in the following spring (B.C. 82), he saw Murena preparing to renew his hostile incursions, he at once determined to oppose him by force, and assembled a large army, with which he met the Roman general on the banks of the Halys. The action that ensued terminated in the complete victory of the king, and Murena, with difficultly, effected his retreat into Phrygia, leaving Cappadocia at the mercy of Mithridates, who quickly overran the whole province. Shortly afterward A. Gabinius arrived in Asia, bringing peremptory orders from Sulla to Murena to desist from hostilities, whereupon Mithridates once more consented to evacuate Cappadocia. Thus ended what is commonly called the Second Mithridatic War.
