Total slaughter of Roman forces from the Cimbri, Teutons and Ambrones tribes, that used their numbers of warrior and auxilia to overwhelm the Roman positions. They did not need to destroy the Roman camp and even most of their cavalry was not used, the Romans simply could not avoid the constant battering for a barbarian win 13-7.
Played twice. (Game 1): 13-11 ; (Game 2): 13-12. Romans can hold their own until they have to deal with the meat of that Germanic Army. That's when the slaughter comes in and they win. Germanics won both games.
