Battles

A battle determines which of the armies will seize the region where the battle takes place. At the end of the battle, the attacking army either retreats or occupies the region. A battle and related maneuvers usually last up to 15 days, or until one of the armies has suffered such serious combat losses that it will lose all combat power and will not be able to continue the battle. If the battle drags on, the army with lower combat capability retreats.

Gameplay Tips
When armies enter battle, it is too late to influence them. Make sure that the side you support has an advantage before the battle begins.
