How many Romans died in the different battles with Spartacus?

It is not known. Spartacus was not the only

leader of the revolt and there are two divergent accounts of the

rebellion and not enough figures of casualties. Spartacus defeated

a praetorian militia of some 3,000 men at the battle of Mount

Vesuvius. A group of rebels was defeated by a consular legion the

battle of Mount Garganus and its leader, Crixus, was defeated.

According to one account Spartacus then defeated two consular

legions. This would amount to some 10,000 men, but there are no

figures bout the number of casualties. According to the other

account Spartacus defeated only one consular army and later was

engaged by two legions further north in Italy and defeated them.

The Romans had limited forces available to them because they were

engaged in two wars, one in Spain and one in Turkey. Eventually,

the Romans gathered a force of eight legions (32,000-48,000 men).

Spartacus was defeated and 6.000 of his men were killed. He

escaped, but was defeated again, with the loss of 12,000 men and

6,000 prisoners were crucified.
