Condition
The only preliminary bombardment authorized is flash bombardment.
After flash bombardment, artillery may be reused.
It is necessary to have 4 artillery present (does not matter which ones) to
do a Rolling Barrage: 1 artillery for the Rolling Barrage +1 artillery for
support, for a total of 2 artilleries per sub-battle.
Advantages
● During the battle, artillery assigned to the Rolling Barrage will do
one bombardment round per sub-battle against the “engaged”
enemy unit each round just before resolving the combat. In the
event of success, the Rolling Barrage increases losses and reduces
the defense.
Disadvantages
● Rolling Barrage is delicate and its effectiveness is unforeseeable.
● The 4 artillery each use 1 MUN; for 4 MUN per round.
● It is forbidden in mountain.
● The Tactic of Infiltration may not be used in conjunction. It is
nonetheless possible to use Stosstruppens or Tanks.
Rolling Barrage Procedure
Heavy artillery: the 4 artillery used for the Rolling Barrage are selected.
Firings: the 2 firings (one per sub-battle) are done on the Rolling Barrage
Table, before each combat round, with the following modifiers:
+1 if the Attacker has a siege artillery (in this sub-battle)
+1 General Nivelle (France), for each of the 2 sub-battles, if he is
at GHQ
+1 if the Attacker benefits from the letter “R” (Order of Battle)
+1 per victorious Offensive** with the Rolling Barrage (max. +2)
-1 for each loss of firing cohesion (See below)
-1 if the Enemy has a siege artillery present (in this sub-battle)
-1 if the Defender benefits from the letter “I”(Order of Battle)
-1 if the Defender has a fortress
-1 if the Defender knows the Combat Tactic “Defense in Depth”
Victorious Grand Offensive**: Western Front (French or Italian) and East
(Russian) only. If the Target region has been taken through the use of
Rolling Barrage during the entire battle. The bonus is acquired as soon as
the Grand Offensive is officially victorious.
Firing Cohesion: each time a firing gives no result, the Rolling Barrage
loses its cohesion. The next firings in this sub-battle have a -1 penalty
(cumulative). Each sub-battle has its own firing cohesion.
Firing Results
There are three possible outcome:
124 World War One: La Grande Guerre 1914-1918
● If the result is ≤ 8, it is a failure (cohesion loss for this sub-battle, a -1
penalty for the next firings, to be accumulated)
● If the result is from 9 to 12, it succeeds. The firing has 2 effects,
before and after the round’s combat result is rolled:
- before: the enemy trench has a temporary result of “r2” (just for the
combat that follows).
- after: the combat result is aggravated by one level
● If the result is 13+, it succeeds with maximum effects:
- before: the enemy trench has a temporary result of “r3” (just for the
combat that follows).
- after: the combat result is even more aggravated, by two levels
The battle continues thus from round to round. Note that the Attacker may
stop his Rolling Barrage at an time in a sub-battle, and continue the battle
without it.
21.7 Gas Warfare
The use of a Gas gives two bonuses: one for preliminary bombardments,
the other (random) increases the attackers’ combat value. In addition, the
very first use of Chlorine gas provokes a terror effect.
21.7.1 Learning
Each Gas technology known provides a +1 bonus to the combat gas
discovery test (Chlorine, Phosgene, and Mustard). Requirements for use
are the following:
● You must have the Gas #1 Technology (Chorine), an artillery, and
have discovered this Tactic.
● The first gas to be used is Chlorine gas.
● Gases are used in the following order: Chlorine (#1), Phosgene (#2),
then Mustard gas (#3). As soon as a gas is used, the next one may
be used any following turn, with a minimum of 1 turn delay between
them.
● It is possible to discover the gases in any order. A non-available gas
is “in waiting”. It becomes available for usage #2, as soon as the
preceding gas has been played.
● Important: the Gas #1 “Chlorine” is automatically available to the
enemy as soon as the technology becomes ‘Public domain’.
21.7.2 Double Usage of a Gas
These two usages are applied together during a battle.
Usage #1: Preliminary bombardment (permanent usage)
This Tactic gives a bonus of +1 to preliminary bombardments.
Usage #2: Attack value (short-lived usage)
This seond use is limited in time. A Gas may be used during 3 consecutive
turns (usage turn + two others). Afterwards, this Gas becomes obsolete for
this usage. Usage #2 of a Gas gives a random bonus to the Attacker’s
