Training Foreign Troops-Roman Evidence?

[Michael Kerr]

I think one of the depictions on Trajan's column is of Dacians besieging a Roman fort in the same manner as the Romans undertook sieges. I have read that one of the conditions for peace made by Decebalus to Domitian was that the Romans supply him with engineers and equipment. They seemed to know a lot about Roman tactics as well but whether the Romans supplied trainers as part of peace terms or conditions or whether they were Roman deserters doing the training I suppose we will never know. :-)
