September 6th, 394 - The Battle of Aquileia (or the Frigidus)

Conflict: Roman Civil Wars

Combatants: Western Romans (Eugenius) vs. Eastern Romans (Theodosius)

Location: Italy

Outcome: Theodosius victory

Following the pacification of Gaul, the Frankish general Arbogast turned on and murdered the Western Roman Emperor Valentinian II and installed Eugenius in his stead. Theodosius, the Emperor of the East, refused to accept Eugenius and assembled an army to invade Italy.

On September 5th, Theodosius engaged in a failed attack on the defensive positions of Eugenius at Aquileia. Theodosius then spent the night re-organizing his men and praying. The next day, he rallied his troops and, aided by a windstorm, smashed the forces of Eugenius. Eugenius himself was killed and the civil war was over.
