A.D. 468. Photo credit: Fourat/Panoramio. Just like the army, the Roman navy has had its fair share of military disasters. In this one, a joint naval expedition (reputedly one the biggest in ancient times) by the Empire and the independent province of Illiricum against the Vandal Kingdom ended in a huge lopsided defeat.his battle marked the first time that a Roman emperor died at the hands of a foreign enemy. Set in the modern-day city of Razgrad, Bulgaria, the battle pitted the Romansâled by the co-emperors Decius and his son Herenniusâagainst the Goths.
Rome was sacked by Visigoths in 410, and though the capital of the West Roman Empire was not Rome at that time, but Ravenna, this was a shock to the idea of the power of the empire. Rome was sacked again in 455 by Vandals. In 474, Julius Nepos came to the throne of the West Roman Empire. Two years later, he was deposed in Italy by a general named Orestes. Orestes could not legally be emperor, because he was not born within the empire, so he put his six year old son on the throne.
