Ambiorix was the leader of the Eburones, a Belgic tribe of north-eastern Gaul (Gallia Belgica), where nowadays Belgium is located, conquered by Julius Ceasar in 57 BC. One day, Ambiorix cunningly warned the Romans that several other tribes were planning to attack and advised them to relocate to another Roman camp so that they would be stronger to battle these troops. The Romans would rather be safe then sorry, so they decided to relocate and join with other Roman troops. While they crossed a valley Ambiorix and his men attacked them from up the hills and slaughtered the whole Roman legion. When Ceasar heard what had happened, he swore to put down all the Belgic tribes. The Roman campaigns against the Belgae took a few years, but eventually the Belgae were no match against 50,000 trained Roman soldiers. The tribes were slaughtered or driven out and their fields burned. The Eburones were history from that point. Ambiorix and his men, however, managed to cross the Rhine and disappear without a trace.
