The Battle of Ad Decimum took place on September 13, 533 between the armies of the Vandals, commanded by King Gelimer, and the Byzantine Empire, under the command of General Belisarius. This event and events in the following year are sometimes jointly referred to as the Battle of Carthage, one of several battles to bear that name. The Byzantine victory marked the beginning of the end for the Vandals and began the reconquest of the west under the Emperor Justinian I.
