Passage: However, later that year, Rome dispatched a military force under praetorian authority to put down the rebellion. A Roman praetor, Gaius Claudius Glaber, gathered a force of 3,000 men, not regular legions, but a militia "picked up in haste and at random, for the Romans did not consider this a war yet, but a raid, something like an attack of robbery." Glaber's forces besieged the slaves on Mount Vesuvius, blocking the only known way down the mountain. With the slaves thus contained, Glaber was content to wait until starvation forced the slaves to surrender.

Question: How many men were gathered by Roman praetor, Gaius Claudius Glaber?
3,000
