A dislodged unit must retreat to an adjacent province that it could ordinary move to if unopposed by other units. Sometimes, a retreat is made deeper into enemy territory.
A unit cannot retreat to :
- a province which is occupied
- the province from which the attacker came
- a province that was left vacant by a standoff during the same turn
If there is no available province to which to retreat, the dislodged unit is immediately disbanded and removed from the mapboard.
Retreats cannot be convoyed or supported.
Disbandment
If two or more units are ordered to retreat to the same province, they all will be disbanded.
If a player fails to order a retreat when necessary, the unit is disbanded.
Also, a unit can voluntarily disband instead of retreating.
