Amazed am I ere I made Zama An analysis of Hannibal’s last battle by Patrick Waterson Slingshot 262, Jan 2009 The �tle palindrome is rather like the standard Hannibal knew that the situa�on he faced had been reconstruc�on of Hannibal’s inten�ons for the ba�le of duplicated – or nearly so – in a previous Punic War Zama. It looks neat but something is missing. (Polybius I.32-34). The year was 255 BC. The Roman army under Regulus had defeated the Carthaginian army We are generally told that Hannibal deliberately sought in Africa, commanded by Hasdrubal, Hanno and Bostar ba�le knowing himself to be inferior in cavalry, collected at a ba�le near the city of Adys, and was ranging freely a disputed number of elephants for reasons that are not from its base at Tunis while a Numidian invasion was wholly clear, brilliantly threw away half his infantry and causing further concern.

The foot Given that Regulus began with around 15,000 total consisted mainly of “a phalanx of Carthaginian ci� zens” infantry, less any losses in the engagement men� oned with some mercenaries, evidently those who had arrived previously, this indicates a standard consular two-legion with Xanthippus. There were placed behind an almost army with allies. He deployed his men “many maniples solid phalanx of elephants, which drew up shoulder-to- deep,” which implies that he deployed six maniples deep shoulder ahead of the Carthaginian troops.
