Out of curiosity, what's the title of Goldsworthy's book you mentioned? Would I be able to find it on Amazon?
There's Roman Warfare (a bit short, IMO), lots of useful stuff in In the Name of Rome: The men who won the Roman Empire, and the one I've used for a lot of the early parts of this guide is The Fall of Carthage (also sold as The Punic Wars).
