The Siege of Cyzicus was fought in 73 BC between armies of Mithridates VI of Pontus and the Roman-allied citizens of Cyzicus in Mysia and Roman Republican forces under Lucius Licinius Lucullus. It was a decisive Roman victory. With the onset of winter, Mithridates's forces faced starvation. The king fled by sea while his army made its way along the coast to the port of Lampsacus. Along the way, they were attacked and destroyed near Cabira along the Rhyndacus River.
