The Battle of the Trasimene Lake was one of Hannibal‘s most splendid victories. The Romans were well aware that the Carthaginian general was a dangerous, capable opponent, and sent out several armies, making sure that he could always be attacked from two sides at the same time. Hannibal, however, managed to elude his opponents, and attacked the army of the Roman consul Flaminius on the northern bank of Lake Trasimene. Roman losses were high; in the following year, only an army of recruits could be sent out, which met its doom at Cannae.
