12.2 Laying Siege
Laying siege to a structure can be a time-consuming process. It consists of a gradual wearing-down of the defender’s will to resist through attrition (i.e. starvation, disease, desertion, etc.). Combat is resolved by comparing the Siege Value of the besieging force to the Siege Value of the defending force (i.e. the besieged force). The siege resolution procedure every turn continues unless the siege is broken.
The siege is broken if the besiegers are leave the region or withdraw from the siege (e.g. attacking other enemy in a field battle counts as withdrawal). All breaches of structures are immediately repaired once they are unbesieged.
At the moment the siege is completed or ceases for any reason, be it because the besieged structure
has fallen, the siege has been broken, or the Legion has moved away from the region, the siege
engines will be automatically destroyed
The sige is broken if
1) besiegers leave the region
2) withdraw from the siege
~~~~~attacking other enemy in a field battle counts as withdrawal
So does that mean if i am the besieger who is in a Defensive Posture w/ a Defend RoE & I am then attacked by a different (ie not the Force being besiged) enemy Force in Offensive Posture that moves into that region....does that mean even if i WIN the combat that the siege is now considered a broken siege....thereby allowing the enemy in the besieged enemy to rebuild/repair all breaches & I lose all crafted siege engines.
Hence, if all of that is true, I want to make certain i fully understand the siege mechanics lest i spend time trying to breach & building siege weapons to then have it all undone by a "spoiling" attach via a smaller enemy force.
