Cyzicus (First Mithridatic War).

Fought B.C. 88, when the army of Mithridates, who was besieging Cyzicus, was hemmed by the Romans under Lucullus, and though the latter, with inferior forces, did not venture on a pitched battle, he fought a series of minor engagements, in which he eventually destroyed the Pontic army, their losses amounting in the end to over 200,000 men.
