The Huns

[Theodosius the Great]

try volunteers from Roman lands? There were apparently enough Romans willing to work for other lords, especially deserters or those forced out because of crimes or tax pressure. And if there were enough germanic volunteers to fight for the Romans, there should have been some willing to go the other way..

Roman traitors and Germanic foederati switching to the enemy ? I've never read about the latter picking up Roman skills and technological knowhow. Foederati, I thought, were just grunts of dubious quality. As for Roman traitors, what rewards could they expect from a barbarian chieftain besides protection and money ? They'd have to live among barbarians for the rest of their lives abandoning the creature comforts of a Roman lifestyle.

Mostly though I'd say Attila would starve cities, not besiege them.

That's amazing if true. So many large cities were razed to the ground by him in Gaul and Italy. The Goths after Adrianople could never starve out Roman cities in the Balkins during Theodosius' entire reign. Was Attila simply more determined in his sieges ?
