14. Battle of Teutoburg Forest (9 CE)
In 9 CE, Roman forces under Publius Quinctilius Varus advanced into Germania, aiming to expand the Empire’s reach. However, they were ambushed in the dense Teutoburg Forest by an alliance of Germanic tribes led by Arminius, a Roman-trained chieftain. Misled by Arminius, the Romans were encircled and suffered near-total destruction, with estimates of 15,000 to 20,000 soldiers killed or enslaved. This catastrophic defeat halted Roman expansion east of the Rhine River. For more details, visit the International Encyclopedia of the First World War. (encyclopedia.1914-1918-online.net)
