Interim Trinobantes, prope firmissima earum regionum civitas, ex qua Mandubracius adulescens Caesaris fidem secutus ad eum in continentem Galliam venerat, cuius pater in ea civitate regnum obtinuerat interfectusque erat a Cassivellauno, ipse fuga mortem vitaverat, legatos ad Caesarem mittunt pollicenturque sese ei dedituros atque imperata facturos;
In the meantime, the Trinobantes, who were one of the most powerful states in that region, sent ambassadors to Caesar. This was the same state from which Mandubratius, a young man seeking Caesars protection, had come to the continent of Gaul to meet him. Mandubratiuss father, Imanuentius, had been the ruler of this state until he was killed by Cassivellaunus. Mandubratius had only survived because he fled. The Trinobantes promise to surrender themselves to Caesar and obey his commands.
