Crassus and Pompey .
Spartacus defeated Lentulus first, who had attempted to surround the slaves, and then both the praetor Arrius and Gellius, who had recently slain Crixus and his Gauls.
Spartacus did not defeat Marcus Licinius Crassus, who, with a massive force of eight legions, routed him and his men. Pompey the Great was sent with reinforcements. He did not actually engaged in any battle, but moped up some 5000 fugitives from the battle with Crassus and he (undeservedly) claimed that he was the one who ended the war.
If you are referring to Sparta, the Greek city state, it never defeated the Romans. If you are referring to Spartacus, he defeated the consular armies of Lucius Gellius Publicola and Gnaeus Cornelius Lentulus Clodianus.
Historical events showed Gannicus as one of the rebel commanders under the leadership of Spartacus. Spartacus outlast all of his commanders during the 3rd serville war. I believe Spartacus tactics in combat would have given him the edge if pitted against any of the other gladiator commanders.
Spartacus and his men were routed by Marcus Licinius Crassus. Pompey the Great, who was coming with reinforcements rounded up 5,000 fugitives from the battle.
Spartacus lost and was killed in the battle of the final defeat
The questions and answers previously given do not provide a reason for Rome's initial defeat by the army of Spartacus. The reason Rome lost the first encounter with Spartacus was Rome's expectation that Spartacus posed no serious threat and so the small force Rome sent to defeat Spartacus was defeated because Spartacus had 90,000 troops at his disposal.
No, Spartacus and his followers were routed by Crassus before Pompey reached the area where they were defeated.
More of their military commanders were graduates of West Point than were union commanders. Thus they had more high quality military training and experience.
