 It is possible that this is the same place as modern Tongeren (Latin "Aduatuca Tungrorum"), except that the term may simply mean "fortification".One reason for doubt is that Caesar seems to indicate that Aduatuca was near the centre of the Eburone territory, and that the main part of this territory lay between the Meuse (Dutch "Maas") and the Rhine, while Tongeren lies entirely to the west of the Maas.After some initial success, the revolt against Caesar failed, and he conquered the area.
