Explanation:

The Battle at Trebia River - 218 B.C.

The Battle at Trebia River in 218 B.C. was a significant military engagement during the Second Punic War between Rome and Carthage. This battle was one of the first major battles of the war and saw the famed Carthaginian general Hannibal outmaneuver and defeat a Roman army. Following a surprise attack in Spain against Roman allies, Hannibal moved his troops into Italy, aiming to bring the war to Roman soil. The Romans confronted Hannibal near the Trebia River, where they were led into a trap. Despite their superior numbers, the Romans were outsmarted by Hannibal's tactics, including an ambush from hidden forces and the use of war elephants, resulting in a catastrophic defeat for the Roman forces.

The historical significance of the Battle at Trebia River echoes throughout time, as it set the stage for the Carthaginian general's campaign in Italy, where he continued to achieve victories until his eventual recall to defend Carthage against a Roman counter-invasion. This battle underscores the brilliance of Hannibal's military strategy and the weaknesses of the Roman legions during the early stages of the Second Punic War.
