Vespasian's Invasion of Italy

The Flavian plan was for Vespasian to remain behind in the east while Musiana led an invasion of the west. When Vetelius learned that a Flavian army was marching on Italy, he dispatched Caesina to stop their advance. The troops couldn't have agreed more and elected Antonius their new general. Instead of waiting for Musiana's to arrive, Antonius went off the reservation and led the legions now under his command into Italy. In other words, the army that ultimately won the war for Vesp asian was never authorized to do what it did.
