Final answer:
Hannibal Barca is the Carthaginian general known as the "man of lightning" for his military prowess during the Second Punic War.
Step-by-step explanation:
The Carthaginian general referred to in the question is Hannibal Barca, often known as "man of lightning" for his swift and strategic military maneuvers during the Second Punic War against Rome. Hannibal is most famous for his audacious crossing of the Alps with his army and war elephants in 218 BCE and his victories in major battles such as Trebia, Lake Trasimene, and Cannae. Despite his early successes, the prolonged war and the strategic counterattacks from the Roman general Scipio Africanus, culminated in Hannibal's final defeat at the Battle of Zama in 202 BCE, effectively ending the Second Punic War and solidifying Rome's dominance over the western Mediterranean.
