Which of the following Roman military commanders did Spartacus NOT defeat?

M. Licinius Crassus, In the battle the inspired Romans dominated the slaves, and they were cut down in huge numbers. By the end, Spartacus himself was wounded and likely killed (his body was never found). Crassus swept survivors and stragglers out of the surrounding countryside by the thousands, and prepared a horrific, if not intimidating punishment. Up to 6,000 rebellious slaves were spaced out along the Appian Way, from Rome to Capua. Here they were crucified and left to rot as a reminder to all future potentials rebellions.
