Hannibal was wonderful, he so nearly beat the boring Romans. Before I found this book, sometime in the mid-seventies, the only thing I knew was a that he'd taken elephants over the Alps, on the basis of which, I undertook a school project on Hannibal.
Yes, it's probably unbalanced, pro-Hannibal in the extreme, but it was well written, and caught my schoolboy imagination. Who knows what happened to that first copy (library book, perhaps), but I went looking for it forty years later and found it every bit as readable, as engaging now as then.
