[4] Bithynia served as a buffer state between Rome and Pontus; feeling threatened Mithridates marched his armies westwards and invade Roman territory.
Lucullus had not advanced far when news came through that Mithridates had made a rapid march westward, attacked and defeated Cotta at the Battle of Chalcedon, and was now besieging him.
[9] After defeating the Mithridatic land forces at the Siege of Cyzicus and the battles of the Rhyndacus and the Granicus, Lucullus moved to the Troad and the Hellespont to raise a fleet.
[14] The Mithridatic commanders choose not to fight a sea battle, but instead defend against the Roman fleet off the coast of Lemnos; they drew up their ships on the beach and fought from their decks.
[14] Lucullus occupied his opponents attention with part of his fleet while secretly landing a contingent of troops on the other side of the island, when these made it across they attacked the Mitrhidatic forces from behind.
