Battle of the Teutoburg Forest
Meanwhile, Germanicus' troops had built a fort on Mount Taunus from where he marched with 30,000 to 35,000 men against the Chatti (probably a region of villages) and slaughtered children, women, and the elderly. The able-bodied men fled across a river and hid themselves in the forests. After that blow, Germanicus marched on Mattium and burned the city down.
