The Dacians: Rome\'s Greatest Enemy?

[Nathan Ross]

J.Caesar's Legions, most of whom would have been men fresh out of the Gaul campaigns, would probably have been superior fighting quality to other newly-raised Roman legions.

I think most of Caesar's Gallic legions had been disbanded by that point, and his veterans given land. They were later reenlisted by Octavian and Antony, but as far as Caasar was concerned they'd already done their bit (and many had been dangerously mutinous about the prospect of going to Africa, let alone Parthia!)

The Alaudae legion, and the mysterious Legio Martia, formed part of the Parthia force and were later shipped back across the Adriatic to fight in the civil wars. But the majority of the legions were probably either newly-raised men or formations of ex-Pompeians and assorted others.
