A.D. 9: In the depths of the Teutoburg Wald, in a landscape riven by ravines, darkened by ancient oak and bisected by fast-flowing streams, Arminius of the Cherusci led a confederation of six Germanic tribes in the annihilation of three Roman legions. Deep in the forest almost 20,000 men were massacred without mercy; fewer than 200 of them ever made it back across the Rhine. To Rome's shame, three sacred Eagles were lost that day. But Arminius wasn't brought up in Germania Magna--he had been raised as a Roman. This is the story of how Arminius came to turn his back on the people who raised him and went on to commit a betrayal so great and so deep, it echoed through the ages.
