Topographical Map of the Catalaunian Plains

[Flavivs Aetivs]

Durocortorum is Reims, Durocatalaunum is Chalons-en-Champagne.

I don't have time to reply to this at the moment, but in a nutshell I'm of the opinion that Attila took the road from Orleans to Reims which took him past Bibe and then north near a 9km ridge near the towns of Avize and Vertus. The ridge is steep and runs north-south which is what Hughes suggests and follows the path Attila took into Gaul (which is his logical route of retreat).

This same ridge was the site of a German entrenchment and was probably bombarded with artillery at the Battle of the Marne in 1916.
