The Battle of Isonzo is the name given to the battle fought on August 28, 489 on the banks of the Isontius River, not far away from Aquileia. This river is now known as the Isonzo in Italian, and Soča in Slovene. This battle should not be confused with the 12 battles of Isonzo during World War I. Theoderic the Great, king of the Ostrogoths, in 489 opened his first campaign against Odoacer to wrest Italy from him. On 28 August, the two armies met on the banks of the Isontius. Theoderic defeated Odoacer, who retreated. A second battle was fought at Verona.
