Not long afterwards the Carthaginians invaded Spain
and were gradually subduing it, when the Saguntines appealed to Rome and a boundary was fixed to the Carthaginian advance by agreement that they should not cross the river Ebro. The Carthaginians, under the lead of Hannibal, violated this treaty by crossing the stream, and having done so Hannibal marched against Italy, leaving the command in Spain in the hands of others. The Roman generals in Spain, Publius Cornelius Scipio and Gnæus Cornelius Scipio, two brothers, after having performed some brilliant exploits were both slain by the enemy. The generals who succeeded them fared badly until Scipio, the son of the Publius Scipio who was killed in Spain, set sail
thither, and making all believe that he was come by a
divine mission and had divine counsel in all things, prevailed brilliantly, and achieving great glory by this success, gave over his command to those sent to succeed him, returned to Rome, and asked to be sent with an army to Africa so as to draw Hannibal out of Italy and to bring retribution upon the Carthaginians in their own country.
