Rome and Carthage entered into peace negotiations, and Carthage recalled Hannibal from Italy. The Roman Senate ratified a draft treaty, but due to mistrust and a surge in confidence when Hannibal arrived from Italy Carthage repudiated it. Hannibal was placed in command of another army, formed from his veterans from Italy and newly raised troops from Africa, but with few cavalry. The decisive Battle of Zama followed in October 202BC. Unlike most battles of the Second Punic War, the Romans had superiority in cavalry and the Carthaginians in infantry. Hannibal attempted to use 80 elephants to break into the Roman infantry formation, but the Romans countered them effectively and they routed back through the Carthaginian ranks. The Roman and allied Numidian cavalry drove the Carthaginian cavalry from the field. The two sides' infantry fought inconclusively until the Roman cavalry returned and attacked his rear. The Carthaginian formation collapsed; Hannibal was one of the few to escape the field.
