Stories are starting to emerge of a Roman/German battlefield in Kalefeld in Lower Saxony. 600 pieces have already been found. What is exciting is that the site dates to the third century and that it is on the wrong side of the Rhine. After the battle of Teutoburg Forest in AD9, it was presumed that the Romans withdrew to their side of the river. At the moment many of the details are being kept under wraps to protect the site from looters.
I have only seen one English report - The Local, Germany's newspaper in English:
“The find can be dated to the third century and will definitely change the historical perception of that time,” Dr. Henning Haßmann told The Local.
The amazing discovery allows an insight in what must have been a dramatic battle between Romans and Germanic tribes. “The find indicates a massive Roman military presence,” Haßmann said.
So far historians believed that the battle of the Teutoburg Forest, which took place in 9 AD, resulted in the Roman’s Empire withdrawal from Germania without any further attempt to conquer the land beyond the Rhine River again. But the unearthing of the battleground near the village of Kalefeld proves that Rome didn't give up its expansionary ambitions until much later than previously assumed.
