Scipio defeated Hannibal and Rome learned a valuable lesson about strategy, improving their Generals cunning. Scipio also introduced a deadly new short sword that he had come across in the Spanish theater of the war, the gladius. Crafted by Celtic, Iberian and Celtiberian tribes these swords were the best in the world and would become the main weapon of the legions. Rome also took away the much greater prize, control of the Western Mediterranean.
