Battle of Bourgaon
The Battle of Bourgaon, or Mount Bourgaon took place in the summer of 535 at Mount Bourgaon in central Tunisia between Byzantine troops and a numerically superior Berber rebels.
The Berber rebels camped on the foothills of the Bourgaon mountain, giving them a defensive advantage over the Byzantines. During the night, Byzantine troops scaled the opposite side of the slope without being noticed and launched an attack from both sides at dawn, catching the Berbers off guard. The Byzantines routed the rebels, reportedly killing or wounding nearly all their fighters and forcing the remaining leaders to flee into the Berber Kingdom of Arris. It marked the end of the first stage of the Berber revolt.
Prelude
Byzantine General Belisarius, after his victory in the Vandalic War in Africa, had to return to Constantinople to deal with rumors against him in the royal court of Justinian I. Belisarius anticipated that the Berbers, who had remained quiet largely out of fear of him, would revolt upon his departure. He placed most of his bucellarii under Solomon's command and instructed him to put down the rebellion. The Berbers rebelled on the news of Belisarius' departure.The Berbers invaded Byzacena and defeated the local Byzantine garrison, ambushing and killing its commanders, Aigan and Rufinus the Thracian, which damaged the morale of the Byzantine troops. After diplomatic entreaties over the winter failed, and with his forces bolstered to some 18,000 men following the arrival of reinforcements, in spring 535 Solomon led his troops into Byzacena. In early 535, Solomon defeated the Berber rebels, under their chiefs Cutzinas, Esdilasas, Iourphouthes, and Mesidinissas, in the Battle of Mammes. The Berbers retreated and regrouped at Mount Bourgaon, while the Byzantines sought to put an end to the revolt.
Battle
The Berbers encamped on the mountain's foothills, having a defensive advantage over the Byzantines. The Berbers, not expecting the Byzantines to actually try and overtake them from the east that had a steep slope, concentrated all their forces on the west, where there was a gentle slope. Solomon's army camped in the valley, expecting the Berbers to descend and engage him in the open, but the Berbers refused to be drawn out.At first, the Byzantine troops lost morale when confronted by their numerically superior enemy. After a speech by Solomon, the troops gained their morale back and prepared for the fight. Solomon sent his commander, Theodorus, with about 1,000 excubitors to climb the eastern side of the mountain. He did not tell this to his own troops to avoid being betrayed. The excubitors climbed up the mountain during the night without being noticed.
At dawn, Solomon advanced his forces to the mountain's outskirts, while Theodorus's troops emerged on the opposite side, encircling the Berbers. Both detachments struck the Berbers with volleys of arrows, causing them to panic and try to flee, but they had no route of escape. The few that survived did so by trampling over the dead bodies of their comrades, and nearly all of the Berber warriors were caught, killed, or wounded. All of the Berber chieftains were able to flee except for Esdilasas, who was caught and taken prisoner. According to Procopius, the Berbers suffered 50,000 casualties, while the Romans suffered none.
