 They went to the Claudian Mountains (a mountain range in Pannonia, in the Varaždin County in northern Croatia) and took a defensive position in the natural fortifications.In Velleius Paterculus’ version, the second rebel force confronted the legions which Caecina Severus and Marcus Plautius Silvanus were bringing to Illyricum (from Moesia and the Roman province of Asia, three and two legions respectively).They surrounded the five legions, their auxiliary troops, and the Thracian cavalry and almost inflicted a fatal defeat.
