Battle of the Tanais River
The Battle of the Tanais River in 373 AD between the Huns and the Alans, was fought on the traditional border between Asia and Europe. The Huns were victorious.

Some historians credit this battle as the beginning of the process of Germanic migration, in which the Huns pushed Germanic tribes into central and northern Europe, resulting in many conflicts between those tribes and the Roman Empire.

It was followed by a joint Hun-Alan invasion of the Gothic kingdom of Ermanaric.
