Gaius Cassius Longinus
Plutarch then goes on to detail a conflict not mentioned in Appian's history. According to Plutarch, Spartacus' army continued northwards to the region around Mutina (modern Modena). There, a Roman army of some 10,000 soldiers, led by the governor of Cisalpine Gaul, Gaius Cassius Longinus attempted to bar Spartacus' progress and was also defeated.
