Vandal king Geiseric sailed his powerful fleet from Carthage up the Tiber to sack Rome.
"The sack of 455 is generally seen by historians as being more thorough than the Visigothic sack of 410, because the Vandals plundered Rome for fourteen days whereas the Visigoths spent only three days in the city" (Wikipedia article on the Sack of Rome [455], accessed 11-22-2008).
