This 56-page sourcebook, written by Neil Smith, chronicles the devastating blow suffered by the Romans in the Teutoberger Wald at the hands of the Germanic tribes led by Arminius in AD 9. The battle, also known by the Romans as the Varian Disaster, saw the Germans ambush and destroy three Roman legions and their supporting troops, ending Roman territorial expansion across the Danube. This book provides army lists and special rules for the Germanic tribes, and scenario rules to describe both the battle and its aftermath.
