This is the only case when opposing stacks may coexist in the same region
after combat.
The besieged units in the interior of a fortress cannot attempt any attack
and have no more offensive ability for as long as the siege lasts. They
cannot come reinforce if a friendly force is fighting a battle outside. Their
role is purely defensive (against an assault).
The Besieger may very well continue a siege with a reduced corps,
without taking into account the enemy corps inside.
If the Besieger is attacked by exterior forces, he benefits from the region’s
terrain for defense.
As long as the siege lasts, the railroad is not useable (if there is one).
12.2.1 Surrender Test
Once the siege is established, and starting from the following turn, a
Surrender Test is carried out automatically during the Final Phase (before
NW adjustments). The fortress surrenders on a 10+.
There are several modifiers that influence this result:
+1 per turn (cumulative) length of the siege: to be counted from
the actual beginning of the test (or at the beginning of the
2nd turn).
+1 if the besieged has 1 or 2 corps.
- ? resistance value of the fortress
-2 port: except if the surrounding sea is under the besieger’s
control.
If the fortress surrenders, all the interior units are eliminated and the
fortress counter is taken off the map. These units don’t count as losses.
Exception: if it is a coastal fortress, the Defender may evacuate his corps
towards a friendly port situated in the same sea.
12.2.2 Siege Firings and Results
Heavy, coastal and certainly siege artillery may be used to reduce a
besieged fortress, by rolling on the Siege Firing Table.
● The Besieger picks his artillery, uses 1 MUN for each one, then
carries out his siege firings, one after the other.
● All Heavy artillery fire together, at one time, on the “heavy” column,
using half of their support values as a bonus, rounded down.
● Siege artillery fires unit by unit on the fortress (on the Siege column),
using half of its support value as a bonus. Mobile coastal artillery is
assimilated into siege artillery.
In all of these cases, an attack against the fortress may follow, no matter
what the result of the siege firings may be. For each firing, a negative
modifier equal to the fortress’ resistance value must be applied.
Each result applies immediately.

● Failure (-): nothing happens.
● Reduction (R): a large fortress is flipped or is “neutralized” if already
flipped. A small fortress is neutralized. A neutralized fortress has no
defense value in the event of an assault (it is to be ignored). If there
are no corps present, 1 round of assault is nonetheless necessary.
However, if there is no assault, or if the assault is Shaken (corps
present), the fortress “recuperates” and regains its defensive abilities
in the next turn. A large fortress stays nonetheless on its reduced
side.
● Elimination (E): the fortress is directly eliminated and its garrison
surrenders immediately. No loss is accounted for the Defender.
12.3 Storming a Fortress
If time is an important consideration, a fortress may be attacked outright
rather than wait for a lengthy siege to be resolved. A direct assault is known
