Hannibal, b. 247 B.C., d. 183 or 182 B.C. Carthaginian general, an implacable and formidable enemy of Rome. Although knowledge of him is based primarily on the reports of his enemies, Hannibal appears to have been both just and merciful. He is renowned for his tactical genius.

Invasion of Italy

From his father, Hamilcar Barca, the defender of Sicily in the First Punic War (see Punic Wars), he learned to hate Rome. He succeeded as general in Spain on the death of his brother-in-law, Hasdrubal, in 221 B.C. After consolidating his position for two years, he besieged Rome's ally Saguntum (now Sagunto), which fell eight months later. Carthage supported him, and Rome declared war (the Second Punic War, 218-201 B.C.).

With a relatively small army of select troops, Hannibal set out to invade Italy by the little-known overland route. He fought his way over the Pyrenees and reached the Rhône River before the Romans could block his crossing, moved up the valley to avoid their army, and crossed the Alps. This crossing of the Alps, with elephants and a full baggage train, is one of the remarkable feats of military history. Which pass he used is unknown; some scholars believe it was the Mont Genèvre or the Little St. Bernard.

He descended into Italy and with his superior cavalry overran the Po valley, winning recruits from the Gallic tribes. A Roman force tried to stop him on the Trebbia, only to be wiped out. In the spring of 217 he crossed the Apennines and marched toward Rome. At Lake Trasimeno he destroyed the main Roman army, but he avoided the strong walls of Rome and moved southward, hoping to stir up a general revolt. In 216 the Romans, having replaced Quintus Fabius Maximus Verrucosus (see under Fabius), attacked the Carthaginians at Cannae, but by brilliant cavalry tactics Hannibal managed to surround the entire force and cut it to pieces. Most of S Italy then allied itself with him, including the important city of Capua. Insufficiently supported from home, Hannibal could not assail Rome and had to content himself with ravaging and reducing smaller places.

Defeat and Death

Beginning in 212 B.C. the tide gradually turned against Hannibal. In 211 the Romans retook Capua, despite his rapid march toward Rome to entice them away. In 207 he fought his way for the last time into a position near Rome, but the defeat and death (207) of his brother Hasdrubal on the Metaurus (Metauro) River made his position hopeless, and he withdrew into the mountains of Bruttium. Recalled to Carthage in 203 to check the advance of Scipio Africanus Major in Africa, he was decisively beaten at Zama (202).

After the conclusion of peace (201), Hannibal became (probably in 196) a suffete, or chief magistrate, of Carthage. He reformed the government and reorganized the revenues in order to pay the heavy tribute imposed by Rome. Denounced to the Romans for allegedly intriguing against Rome, he fled (195) to Antiochus III of Syria. He took a small part in Antiochus's war with Rome, and after the Syrian defeat he fled again, this time to Bithynia. About to be delivered to the Romans, he poisoned himself.

Hannibal, city (1990 pop. 18,004), Marion and Ralls counties, NE Mo., on the Mississippi River; inc. 1845. It is a river port and shipping center. Industries include meat canning, printing, and the manufacture of boats, electronics, and wood and metal products. Agriculture and tourism are also important. Hannibal is famous as the boyhood home of Mark Twain; his house has been preserved, and a museum, a statue, a lighthouse, and a bridge across the Mississippi commemorate him. The famous Mark Twain cave is nearby. Hannibal-LaGrange College is also located there.

Hamlin, Hannibal, 1809-91, Vice President of the United States (1861-65), b. Paris, Maine. Admitted to the bar in 1833, he practiced at Hampden, Maine. He was a Maine legislator (1836-40, 1847), a U.S. Representative (1843-47), and a U.S. Senator (1848-57). As a Democrat he supported Franklin Pierce's administration, but left (1856) his party when it adopted a strong proslavery platform, and joined the Republican party; in the same year he was elected governor of Maine. After a few weeks he resigned to reenter (1857) the U.S. Senate, where he became increasingly prominent. Geographical and political considerations made him a natural choice as Abraham Lincoln's running mate in 1860. As Vice President during the Civil War he presided over the Senate with ability and took part in a variety of governmental wartime activities. He returned to the Senate (1869-81), supporting the Reconstruction and the economic policies of his party. He was minister to Spain in 1881-82.

(born 247 BC, North Africa—died circa183–181 BC, Libyssa, Bithynia) Carthaginian general, one of the great military leaders of antiquity. Taken to Spain by his father, the Carthaginian general Hamilcar Barca (d. 229/228 BC), he was sworn to eternal enmity with Rome. After the death of his father and brother-in-law, he took charge of Carthage's army in Spain (221). He secured Spain, then crossed the Ebro River into Roman territory and entered Gaul. He marched over the Alps into Italy; encumbered by elephants and horses, he was beset by Gallic tribes, harsh winter weather, and defection of his Spanish troops. He defeated Gaius Flaminius but was severely harassed by Quintus Fabius Maximus Cunctator. In 216 he won the Battle of Cannae. In 203 he left for northern Africa to help Carthage fend off Scipio Africanus the Elder's forces. He lost decisively to Scipio's ally, Masinissa, at the Battle of Zama but escaped. He headed the Carthaginian government (circa 202–195); forced to flee, he sought refuge with Antiochus III, whose fleet he commanded against Rome, with disastrous results. After the Battle of Magnesia (190) the Romans demanded he be handed over; he eluded them until, seeing no escape, he took poison.
