Summary of Book XXI

IN this book is described the beginning of the Second Punic War, and how Hannibal, the general of the Phoenicians, crossed the river Ebro in violation of the treaty. Besieging Saguntum, a city belonging to allies of the Roman People, he captured it in the eighth month. These injuries led to the dispatch of ambassadors to the Carthaginians, to complain. On their refusing satisfaction, war was declared against Carthage. Hannibal, after surmounting the passes of the Pyrenees, traversed Gaul—having routed the Volcae, who had attempted to stop him—and arrived at the Alps. After a troublesome passage of these mountains, in the course of which he also defeated in several battles the Gallic mountaineers, when they blocked his way, he descended into Italy and routed the Romans in a cavalry battle near the river Ticinus. In this battle Publius Cornelius Scipio was wounded and was saved by his son, who later received the name of Africanus. Again a Roman army was routed near the river Trebia. After this Hannibal crossed the Apennines, with great distress to his soldiers, because of violent storms. In Spain Gnaeus Cornelius Scipio fought successfully against the Phoenicians and captured the enemy's general, Mago.¹
