Lucullus, based in Cilicia, had foregone his planned invasion of Pontus from the south to come north and resque his colleague the proconsul Marcus Aurelius Cotta, whom Mithridates had besieged at Cyzicus on the Sea of Marmara. Lucullus's five legions began an effective counter-siege trapping Mithridates' army before Cyzicus.

With the onset of winter and running low on supplies, Mithridates decided to sent his sick, his wounded, and his cavalry east into Bithynia. The Pontic column was commanded by Neoptolemus, who was the brother of Archelaus. In the middle of a snowstorm, Lucullus met these forces with ten cohorts along the banks of the Rhyndacus. The Romans had a small advance guard of auxiliaries and cavalry on the opposite bank of the river. The combined Roman forces attacked. The Pontic forces turned to defend themselves. The battle was hard, and the Mitridatic forces fought bravely, but they could not withstand the pressure of the Roman attack. Plutarch and Appian record 15,000 men and 6,000 horses as being captured during the battle.[1]

The disaster at the Rhyndacus combined with the famine and plague which had struck his main army forced Mithridates to completely abandoned his position, sailing north while his army marched overland. Lucullus again routed them at the confluence of the Aesepus and Granicus Rivers slaughtering many.
