The main source for almost every aspect of the Punic Wars is the historian Polybius ( – ), a Greek sent to Rome in 167BC as a hostage. His works include a now-largely lost manual on military tactics, but he is now known for "The Histories", written sometime after 146BC. Polybius's work is considered broadly objective and largely neutral as between Carthaginian and Roman points of view. Polybius was an analytical historian and wherever possible personally interviewed participants, from both sides, in the events he wrote about. He accompanied the Roman general Scipio Aemilianus during his campaign in North Africa which resulted in the Roman victory in the Third Punic War.
