Manual - Steam

undefended, the battle ends after a given time. If a defending army attacks the plunderer,
you can choose to lead your army and a battle will be spawned in Battle View.
This battle will feature a rural area and the objective is either to defend the rural area
or to destroy the defending army. If the plundering army wins the battle, the rural area
is destroyed.
Town Assault
The town assault automatically occurs whenever an army attacks a town without a
wall. If you chose to lead the battle, then a battle will be spawned in Battle View. If your
army occupies the town, then you are the defender and your objective is to defend the
town. If you are the attacker, then your troops are placed outside the town and your
objective is to conquer the town. If the attacking army wins, the province will fall into
their hands, as there is but one town per province. The defender can use up to two
armies to defend his castle, as well as the garrison and the castle guards from the
Town Watch building. The attacker can have up to two armies engaging in this battle.
Siege
If the town has a Palisade, Stone Wall or Bulwark, the attacking army can decide to
lay siege to the town in order to starve them out. The siege lasts as long as the town
has food reserves or until the attacking army’s food reserves are gone. The attacker
can decide to assault the town at any time, at which point the Town Assault mechanics
come into play. However, the defending army can decide to try to break the siege,
and again the Town Assault map will be loaded. The town gives up when it runs out of
food, and the province falls into the hands of the attacker.
