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.
War engulfed the region, starting from when the Ostrogoths were driven out to the various and massive Gothic attacks upon the region (around the 6th century). Life became truly miserable, and the population of Rome declined from some 300,000 towards the fall of the Roman Empire to 35,000 by the mid 6th century. Those few Romans that remained lived in the ruins of their former glory.
