What is "aduatuci"

The Aduatuci or Atuatuci were, according to Caesar, a Germanic tribe who had been allowed to settle amongst the Germanic tribes living in east Belgium. They descended from the Cimbri and Teutones, who were tribes thought to have originated in the area of Denmark. Much later, the Aduatuci sent troops to assist their Belgic neighbours, especially the Nervii, in the Battle of the Sabis, but were too late. They were later defeated by the Romans after withdrawing to a fortified city. After their defeat by Caesar they disappear from the written record, but their survivors possibly contributed to the later tribal grouping known as the Tungri in Roman imperial times.

Before the Roman attack in 57 BC the oppidum of the Aduatuci (possible modern day Namur in Belgium or near the city of Thuin) were home to 57,000 including refugees fleeing the Romans. The oppidum of the Aduatuci were seized by the Romans and after the fall of the city with 4,000 dead the entire surviving population of 53,000 were sold as slaves.
