A Who's Who of World Mythology : Baduhenna

Baduhenna is a Teutonic/Frisians goddess of war and storms. The word “badwa” means battle or slaughter and “henna” usually refers to groups of matrons. During the Frisian rebellion in 28 AD, a Roman army was slaughtered by the Frisians in the Baduhennawald, a holy wood dedicated to Baduhenna. This sacred forest was probably located to the north of the city of Velsen in the modern Dutch province of Noord-Holland, though the exact location may have been the city of Heiloo (“hei” possibly meaning holy, “loo” meaning forest). It is said she received a sacrifice of nine hundred Roman POWs in her woods.
