In the history of war, only a select few men always make the list of greatest generals. Napoleon. Caesar. Alexander. They are always joined by Hannibal, who has the distinction of being the only man who nearly brought Rome to its knees before its decline almost 700 years later. Rome never suffered a more horrifying defeat in its history than at Cannae, and indeed, Hannibal nearly rewrote the course of Western history during the Second Punic War. Even today there remains great debate on just how he accomplished his masterful invasion of Italy across the Alps. Since his army included war elephants, historians still argue over exactly where and how he crossed over 2,000 years after he managed that incredible feat. 

While he remains far less known than Hannibal, Publius Cornelius Scipio, the man who has become known to history as Scipio Africanus, is widely regarded as one of the greatest military leaders of all time. In the space of less than 10 years, the genius of Scipio took Rome from being on the brink of utter destruction to becoming the dominant power in the Mediterranean. He displayed not just acute understanding of the tactical needs of the battlefield but also a strategic overview that consistently allowed him to confound his enemies. Scipio has been described as "the embodiment of grand strategy, as his campaigns are the supreme example in history of its meaning."
