In the battle of Lake Trasimene of 217 BC, Hannibal rose victorious against the Romans that saw their commander Flaminius die while on the battlefield. Hannibal caused a massive loss to the Romans when he ambushed them near lake Trasimene. This ambush took place between the Cortona Hills and the lake when Hannibal took the Romans by their jugular and emerged a winner with very few losses to his side.
The battle of Trebia was fought between Hannibal’s forces and Romans with the latter being commanded by Sempronius Longus. In this battle Carthaginians emerged as the winners as they put up a great show led by Hannibal’s infantry constituted of Celts, Africans and Spanish. The war also saw the use of many of Hannibal’s war elephants and the hidden attack by his brother. Out of a total of 40,000 soldiers, merely 20,000 of them went back safely.
Counted as a very big event of the 2nd Punic War, Hannibal’s crossing of the Alps is perhaps one of the greatest moves to attack the Romans without giving them any chance to retaliate back. Hannibal Barca was a tactful and genius commander who knew of the military prowess of the Romans. He had his spies all over Italy and was in the lookout for an opportunity to strike the Romans when they were least prepared. Hence, with all his preparations, he marched across the steep landscape of Alps and caused a massive blow to the Romans.
These three wars witnessed the use of intelligence, first by Hannibal Barca, and then by the Romans who learnt a few important lessons from the Carthaginians. Hannibal had his spies all over Rome who informed him about the latest news about Roman military. The Gallic spies infiltrated the senate at Rome and led to Hannibal’s numerous victories all though the war. The Romans later adopted this practice of employing spies and won other major events under general Scipio Africanus.
The Battle of Cannae was one of the greatest victories for Hannibal and his troops in the 2nd Punic War. It was fought on the shores of Aufidus River and saw Numidian horse cavalry fight off the Romans with courage and tact. This battle led to a loss of 2700 cavalrymen and about 45,500 infantry soldiers for the Romans. Many hundreds of them were imprisoned. In this battle, the Romans fought with the Carthaginians under the command of consul Lucius Aemilius Paullus.
