The Battle of Tricamarum occurred during the Vandalic War, a conflict initiated by the Byzantine Empire under Emperor Justinian I to reclaim territories held by the Vandals in North Africa. General Belisarius led the Byzantine forces which consisted of approximately 10,000 men against King Gelimer’s Vandal army, which had secured the region. The battle took place on the plains near Tricamarum, strategically chosen to execute a well-planned assault. Belisarius employed a combination of cavalry tactics and infantry formations to counter the Vandal's stronghold effectively.

As the battle commenced, Belisarius used deceptive tactics to draw the Vandal forces into overextending their lines. The complex maneuvers of the Byzantine troops led to confusion within the Vandal ranks. Gelimer, although initially able to engage, was unable to sustain his forces against the disciplined approach of Belisarius and the pressure mounted by the Byzantine flanks. The defeat at Tricamarum marked a turning point in the campaign, as it showcased the prowess of Byzantine military tactics and the weakened position of the Vandal leadership.

Following this significant engagement, the remnants of the Vandal forces retreated, leading to the eventual siege of their capital, Carthage. This battle not only impacted the Vandal kingdom but also set the stage for the wider Byzantine reconquest efforts across North Africa and showcased the effectiveness of General Belisarius as a key military leader for the Byzantine Empire. The victory at Tricamarum reinforced the emperor's ambitions to restore the Western Roman Empire's former territories.
