Archaeologists have found more than 600 relics from a huge battle between a Roman army and Barbarians in the third century, long after historians believed Rome had given up control of northern Germany.

"We have to write our history books new, because what we thought was that the activities of the Romans ended at nine or 10 (years) after Christ," said Lutz Stratmann, science minister for the German state of Lower Saxony."Now we know that it must be 200 or 250 after that."
