6.4.1.3.2 Overrunning Enemy Armies
To avoid large armies having to battle with very small armies, and thus receiving a rise in experience from their battle win, the overrun rule has been introduced in Austerlitz:
When two armies meet and the ratio of their sizes is bigger than 8:1 then the smaller enemy is automatically destroyed and the larger army continues its movement. This is the case even when the smaller enemy is in a fortress (see 7.1.8.1., p68).
An overrun will not take place if you moved two or more separate armies, over the same co-ordinate attempting to overrun an enemy, and in total they meet the required ratio for an overrun. An overrun would only happen if the required ratio is met by one of the armies.
| Defender | Attacker |
| 1 brigade | Min of 8 brigades |
| 2 brigades | Min of 16 brigades |
| 3 brigades | Min of 24 brigades |
| 4 brigades | Min of 32 brigades |
| 5 brigades | Will always stop the enemy and a battle will occur |
The overrun-rule will also apply if the smaller army meets the larger army during its own movement phase. The overrun will be indicated on your turn report with the number of brigades you either overrun or lost in an overrun.
