Continuing distrust led to the renewal of hostilities in the Second Punic War when Hannibal, a member of the Barcid family of Carthaginian nobility, attacked Saguntum, a city with diplomatic ties to Rome. Hannibal then raised an army in Iberia and famously crossed the Italian Alps with elephants to invade Italy. In the first battle on Italian soil at Ticinus in 218 BC Hannibal defeated the Romans under Scipio the Elder in a small cavalry fight. Hannibal's success continued with victories in the Battle of the Trebia, the Battle of Lake Trasimene, where he ambushed an unsuspecting Roman army, and the Battle of Cannae, in what is considered one of the great masterpieces of tactical art, and for a while "Hannibal seemed invincible", able to beat Roman armies at will.
