Laze by is am excellent historian and this is a fine study. He sets up Hannibal’s march into Italy and thereafter covers the war in depth. Rather than a year by year chronology he divides his history into sections. He looks at Hannibal primarily, of course, but he also investigates the campaigns in Spain, Greece, and in the end in Africa. This really helps in understanding the overall course of the war.
Lazenby admires Hannibal’s military genius, and he thinks he had a plausible strategy. his Hannibal does not want to destroy Rome (one reason why he does not march on the city after Cannae), he wants to confine it to Italy.
However, and here Lazenby’s admiration for the Senate’s leadership comes forward, he greatly underestimated Rome’s resilience and the loyalty of most of its allies. Rome’s resources, both human and financial, were stretched by the long war, but in the end they held.
Lazenby sees Scorpio as a fine general and leader, but his triumph at Zama was due to the superiority of Rome’s army, not its general.
This is a well written and very informative study. It’s only flaw is being a little outdated. Lazenby reissued the book, but did not include new studies.
