Greig Watson at the BBC wrote a good piece on the Battle of Teutoburg Forest and was kind enough to quote me:
Three days of blood-soaked butchery in the unfamiliar forests of Germany culminated in one of the Roman Empire's darkest moments, and may have helped shape the Europe of today.
As many as 30,000 Roman soldiers, along with countless slaves and families, died at the hands of people they regarded as barbarians, who were led by a man they regarded as a friend.
Did the Varian Disaster, which took place exactly 2,000 years ago and stunned the Roman Empire into a temporary paralysis, mark a turning point in its all-conquering mindset? Does the slaughter in the Teutoburger Forest still affect us today?
Adrian Murdoch, author of a book on the battle, said the shockwaves were immense.
"The battle was not only the Roman Empire's greatest defeat, but it definitely changed European history in ways which are being felt still now," he said.
