The Battle of Tricamarum took place on December 15, 533 between the armies of the Byzantine Empire, under Belisarius, and the Vandal Kingdom, commanded by King Gelimer, and his brother Tzazon. It followed the Byzantine victory at the Battle of Ad Decimum, and eliminated the power of the Vandals for good, completing the "Reconquest" of North Africa under the Byzantine Emperor Justinian I. The main contemporary source for the battle is Procopius, De Bello Vandalico, which occupies Books III and IV of his magisterial Wars of Justinian.
