It might be useful, when reading David Anthony Durham's Pride of Carthage, A Novel of Hannibal, to acquaint oneself with Phoenician and Carthaginian history.
Wikipedia (handle with care, as usual) has two pages: Phoenicia and Carthage.
It mentions the awsome but difficult to navigate site A Bequest Unearthed, Phoenicia, Encyclopedia Phoeniciana, which includes a timeline of Carthaginian history. Supposedly, this site contains 1,000 individual pages!
As books go, there is the lavishly illustrated The Phoenicians, edited by Sabatino Moscati, and The Fall of Carthage : The Punic Wars 265-146BC (Cassell Military Paperbacks) by Adrian Goldsworthy. Many more books on the subject can be found at Amazon.com.
