(present-day Iznik). Although Lucullus commanded 30,000 infantry and 2,500 horse, he was daunted by the size of the opposing army and reluctant to engage. The arrival of an omen, as reported by Plutarch, was thus fortuitous: No battle occurred. For Marius, delay posed a logistical problem. He had only a few days of supplies for his troops. Lucullus learned of the shortage through prisoner interrogations and decided to wait him out. Marius was forced to move on without the fight he had sought. The Siege of Cyzicus While Mithridates was besieging Cyzicus, Lucullus and his army arrived; the Romans, with the help of some turncoats, were able to establish a counter-siege, trapping Mithridates' army on the Cyzicus peninsula. During the siege Mithridates sent his cavalry away, with the sick and the wounded, but they were ambushed and slaughtered at the river Rhyndacus. In the middle of a snowstorm, Lucullus met these forces with ten cohorts and attacked them in mid-crossing on both sides of the river. Plutarch and Appian record 15,000 men and 6,000 horses as being captured during the battle. The disaster at the Rhyndacus combined with the famine and a plague which had struck his main army forced Mithridates to completely abandon his position, sailing north while his army marched overland. Lucullus pursued the army and defeated them at the confluence of the Aesepus and Granicus Rivers, slaughtering many (20,000 were killed while crossing the river Granicus). Eventually, of the 300,000 who had set out for Bithynia, only 20,000 effective troops remained. The siege of Cyzicus and the subsequent retreat could be considered an unmitigated disaster. The naval campaign Marcus Marius, having survived the Cyzicus campaign, had taken to the sea. Along with Mithridates's admirals Alexandros the Paphlagonian and Dionysios Eunuchos ("the Eunuch"), he was placed in joint command of 50 ships and 10,000 handpicked men, among them, in the words of Mommsen, "the flower of the Roman emigrants." Their intention seems to have been to sail east into the Aegean, but Lucullus mounted an attack against them. He captured a detachment of 13 ships between the island of Tenedos and the mainland harbor of the Achaeans. The main Pontic force, however, had drawn their ships to shore at a site difficult of approach, the small island of Neae between Lemnos and Scyros; Lucullus then sent infantry by land across Neae to their rear, killing many and forcing
