The Dacians: Rome\'s Greatest Enemy?

[M. Demetrius]

No doubt Leg XE was a solid, experienced legion. They also were involved in the mutiny at the end of De Bello Gallico. Some of that legion may have stayed in service, but didn't the bulk of it retire and take pension? Wasn't that the reason they were mutinying in the first place?

Then the reformed LXE sided with Marcus Antonius in the Augustan Civil War, and lost their preeminent status. At least that's one version of their history.
