Thanks!Here's a bit more information in English:
The massacre of the Usipetes and Tencteri - Ancient Warfare - Karwansaray Publishers
To clarify: the archeological findings are not new. The remains of whatever massacre took place there have been uncovered over the past few decades. Recent research based on radiocarbon dating has established that the victims were not locals - they came from East of the Rhine - and it links them to the right period of time. The location more or less corresponds with Caesar's writings, as do the remains of so many men, women and children with wounds inflicted by (Roman) weapons.
Yes, indeed - bones are constantly being extracted from the ground in that area all the time for the last 30 years. So the findings are not new (or at least not all of them), but scientists have managed to link them with that historical event from 55 BC only recently.
