Battle Summary
In combat, units are eliminated according to the following rules:
1. A normal army eliminates a normal enemy army on a roll of 5 or higher.
2. A Roman or cavalry army eliminates a normal enemy army on a roll of 4 or higher.
3. Roman and cavalry armies are eliminated on a roll of 6 or higher.
4. Any defending army in a difficult terrain area is eliminated on a roll of 6 or higher. This rule takes precedence over rules 1 and 2.

Any Roman armies in an area with a Roman fort must be eliminated by an attacker before the fort may be eliminated. Thus a die roll of 5 will not eliminate the fort unless any Roman armies present in that round are eliminated by rolls of 6.
