The Battle of Cannae: History and Total War Recreation
The Roman Army Meets Hannibal in Southern Italy
In 216 BC the Roman Republic sent eight legions south to crush Hannibal’s invasion. The two sides met near the village of Cannae on open ground beside the Aufidus River. Rome fielded roughly 80,000 men. Hannibal commanded about 50,000 troops, including Spanish and Gallic infantry plus Numidian cavalry.
How the Double Envelopment Worked
Hannibal placed his weakest infantry in the center and held his best troops on the flanks. As the Roman line advanced, the center gave ground in a controlled retreat. This drew the Romans into a deep pocket. At the same time Hannibal’s cavalry routed the Roman horse on both wings, then swung behind the infantry to close the trap.
The result was one of the bloodiest single-day defeats in history. Ancient sources record around 50,000 Roman dead. Only a few thousand escaped.
Force Comparison at Cannae
| Side | Infantry | Cavalry | Total |
|---|---|---|---|
| Rome | 70,000 | 10,000 | 80,000 |
| Carthage | 40,000 | 10,000 | 50,000 |
Setting Up Cannae in Total War Rome II
Load a custom battle in Rome II and select the 216 BC scenario. Place Hannibal’s Spanish and Gallic infantry in the middle with weaker Gallic units forward. Hold the African veterans on the wings. Position your Numidian light cavalry on the right and heavier Spanish horse on the left. Let the AI Roman player advance while you keep your center moving backward in good order.
- Keep cavalry hidden behind hills until the Roman wings commit.
- Once the center bows, swing both cavalry groups around the Roman rear.
- Time the infantry wings to fold inward when the cavalry strikes.
Practical Tips for Players Trying the Tactic
Speed matters. If your cavalry takes too long to return, the Roman center will break through your weakened line. Test the setup on medium difficulty first, then move to legendary. Watch the morale bars on the Roman hastati once they realize they are surrounded; that is usually the moment the formation collapses. Small changes in starting distance or terrain height can shift the timing by thirty seconds, so adjust until the pocket closes cleanly.
