The Pannonian Revolt Begins
Contributed by David Verne
Following Tiberius' withdrawal of the majority of Roman troops in Pannonia and Dalmatia for a campaign in Germany, the discontent from Roman rule has flared into a revolt. The rebel generals, Pennes and two unrelated men both named Bato, have a reported 200,000 infantry and 9,000 cavalry between them, although ancient historians tend to exaggerate numbers. The rebel army quickly overwhelms the auxiliaries and the few legionaries in the province, but several fortified towns remain under Roman control. By the end of the summer, the rebels have seized almost the entire province, sent raiding parties into Macedonia and Greece, and have begun to plan an invasion of Italy. Italy is in a panic due to so much territory so close to Italy held by an enemy. All veterans in Italy are called back into service, emergency levies are held, and wealthy families have to provide freedmen as soldiers. Tiberius is ordered to return from Germany and take command of the army to crush the revolt.
