If the legions had been transferred, rather than newly raised, I would have thought that the transferred legion would disappear from the sources and therefore later identifiable as a legion transferred to Crassus in Syria.

Which seven legions did Crassus lose at Carrhae in 53BCE? I have read over Plutarch and Dio's accounts, but they vague as to where the legions were raised or what their name and number was. By comparison we know that it was the XVII, XVIII and XIX that were lost by Varus at Teutoburg Forest in 9CE. Any help would be much appreciated. Cheers
