What this dot point is asking
This dot point covers Hannibal's masterpiece, the Battle of Cannae (216 BC), and the harder question that follows: why he could not win the war in Italy despite such victories. You need the tactics of Cannae (the double envelopment), the crisis it caused, the Roman response (the Fabian strategy), and the structural reasons Hannibal could not finish Rome off. Expect the 25-mark essay to turn on whether Hannibal could ever have won.
The answer
The Battle of Cannae (216 BC)
The crisis for Rome
Yet Rome refused to surrender, which is the turning point of the whole story.
The Fabian strategy
Why Hannibal could not win in Italy
So Hannibal could win battles but not the war, because Rome's manpower and alliances held.
Examples in context
A model answer weighs Hannibal's battlefield genius against the structural reasons he could not finish the war, and reaches a clear judgement.
Try this
Q1. What tactic did Hannibal use to win at Cannae? [Knowledge recall]
- Cue. A double envelopment: he let his centre give way to draw the Romans forward, then surrounded them with his stronger wings and cavalry.
Q2. Explain why Hannibal could not win the war in Italy despite Cannae. [Short explanation]
- Cue. Because he lacked the siege equipment and numbers to take Rome, most of Rome's Italian allies stayed loyal, Carthage sent few reinforcements, and Rome could replace its losses and adopted the Fabian strategy of delay, so he could win battles but not the war.

For the statement. Hannibal lacked siege equipment and numbers to take Rome, most Italian allies stayed loyal to Rome, Carthage gave him little support, and Rome could replace its losses and adopt the Fabian strategy of delay.
Against the statement. After Cannae Rome was in deep crisis, some allies (Capua) defected, and a decisive stroke might have broken Rome's will.
Judgement. Weigh Hannibal's battlefield brilliance against the structural reasons he could not finish the war, and reach a supported conclusion, for example that he could win battles but not the war because Rome's manpower and alliances held.
