This is a reference to one of Pompey’s commands, early in his career, against the rebel supporters of Marius, the popularist leader and enemy of Sulla. Sulla crushed the populares power in Rome when he returned from campaigns in the east in 83 BC and set himself up as dictator of Rome. After a civil war in Italy, the remainder of the Marian forces fled.
