Within three hours, roughly 15,000 Romans were dead, Flaminius himself among them, killed in the confusion before any coherent Roman formation had been established. The survivors fled into the lake and drowned or were captured. It was the largest ambush in ancient military history, executed with a precision that modern military historians still use as a case study in the application of terrain and concealment.</p>
