Siege of Mytilene in 81 BC
The Siege of Mytilene in 81 BC was a military conflict that took place during the Roman Republic’s campaign against the Kingdom of Pontus, led by King Mithridates VI. Mytilene was a fortified city located on the island of Lesbos in the Aegean Sea.
At the time, the Roman general Lucius Licinius Murena was leading the Roman forces in the region. He had been sent by the Roman Senate to confront Mithridates VI and his allies. Mytilene was a strategic location that Murena sought to control as part of his campaign.
During the siege, Murena’s forces surrounded the city and initiated a blockade to cut off its supplies. The Roman army launched assaults on the city walls, attempting to breach the defenses and gain entry into Mytilene. The defenders of Mytilene, led by the city’s governor, put up a determined resistance.
The exact details and duration of the siege are not extensively recorded, but it is known that the Romans eventually succeeded in capturing Mytilene. The city fell to Rome’s forces, and the Roman army took control.
The outcome of the Siege of Mytilene was part of a larger Roman campaign against Mithridates VI, who was ultimately defeated by the Romans under the leaderships of generals Marcus Minucius Thermus and Lucius Licinius Lucullus. The Roman victory in the war marked a significant setback for Mithridates VI and his Pontic Kingdom.
The Siege of Mytilene serves as an example of the Roman Republic’s military campaigns in the eastern Mediterranean during the late Republic period. It demonstrates the Roman expansionist policies and the use of sieges as a tactic to subdue and control strategic locations in their pursuit of regional dominance.
