At a later time the barbarians took the field against the Romans with a greater array. And Sergius went to join his uncle Solomon, in order that he too might go to meet the enemy with a larger army; and he found there his brother Cyrus also. And the barbarians, coming into Byzacium, made raids and plundered a great part of the country there; and Antalas (whom I mentioned in the preceding narrative[64] as having remained faithful to the Romans and as being for this reason sole ruler of the Moors in Byzacium) had by now, as it happened, become hostile to Solomon, because Solomon had deprived him of the maintenance with which the emperor had honoured him and had killed his brother, charging him with responsibility for an uprising against the people of Byzacium. So at that time Antalas was pleased to see these barbarians, and making an offensive and defensive alliance with them, led them against Solomon and Carthage.
And Solomon, as soon as he heard about this, put his whole army in motion and marched against them, and coming upon them at the city of Tebesta, distant six days’ journey from Carthage, he established his camp in company with the sons of his brother Bacchus, Cyrus and Sergius and Solomon the younger. And fearing the multitude of the barbarians, he sent to the leaders of the Leuathae, reproaching them because, while at peace with the Romans, they had taken up arms and come against them, and demanding that they should confirm the peace existing between the two peoples, and he promised to swear the most dread oaths, that he would hold no remembrance of what they had done. But the barbarians, mocking his words, said that he would of course swear by the sacred writings of the Christians, which they are accustomed to call Gospels. Now since Sergius had once taken these oaths and then had slain those who trusted in them,[65] it was their desire to go into battle and make a test of these same sacred writings, to see what sort of power they had against the perjurers, in order that they might first have absolute confidence in them before they finally entered into the agreement. When Solomon heard this, he made his preparations for the combat.
