He also attempted to conquer Roman Gaul (modern France), crossing the Rhine in 451 and marching as far as Aurelianum (Orléans) before being defeated at the Battle of the Catalaunian Plains.
- Subsequently he invaded Italy, devastating the northern provinces, but was unable to take Rome. He planned for further campaigns against the Romans but died in 453.
