A.D. 468. Photo credit: Fourat/Panoramio. Just like the army, the Roman navy has had its fair share of military disasters.

In the fourth century AD, however, what Pliny the Elder had called the âimmense majesty of the Roman peaceâ was menaced by invasions of Germanic peoples from beyond the frontiers of the Rhine and the Danube. Among them were the Visigoths, whose leader from around 395 was a chieftain in his mid-20s named Alaric. That same year also saw the death of the Emperor Theodosius the Great, after which the Roman Empire was divided into eastern and western halves under his sons, Arcadius in the east and the ten-year-old Honorius in the west.
