Lazic War 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.

The main contemporary source for the battle is Procopius, De Bello Vandalico, which occupies Books III and IV of his magisterial Wars of Justinian.

Vandal king Gelimer set up at Bulla Regia in Numidia, about 150 km (90 mi) to the west of Carthage (at what is now the western border of modern Tunisia).

Belisarius had fortified the city in the twelve weeks since Ad Decimum, but knew about Gelimer's agents and could no longer trust the Huns in his forces.

The two forces met at Tricamarum, some 50 km (30 mi) west of Carthage, and the Byzantine cavalry immediately charged the Vandal lines, reforming and attacking two more times.

Gelimer realized that his kingdom was lost, and attempted to flee to Spain, where some Vandals still remained, not having followed the main forces when they crossed into North Africa years earlier.
