condition known as the “Fog of War”. Essentially, the position of enemy<br />
forces is withheld unless players are able to “detect” their presence. Keep<br />
in mind, however, that a player’s ability to detect an enemy is somewhat<br />
offset by the enemy’s ability to hide.<br />
These rules simulate the uncertainty of war conditions.<br />
9. Supply<br />
One of the most daunting challenges faced by any military leader is<br />
keeping an army supplied with all the goods and services it needs to<br />
maintain itself in the field.<br />
● Supply is checked at the beginning of each turn, before movement, for<br />
all units on the front that is played. Supply is checked also at the end<br />
of the Military Phase.<br />
● Supply is checked principally through HQs and the railways. Each unit<br />
must be a maximum of 2 regions from a supply source or relay (itself<br />
which must be 2 regions from another), knowing that a railway allows<br />
any number of regions to be linked along the track towards a source.<br />
● Supply influences the placement of reinforcements, unit strength and<br />
combat.<br />
9.1 Definitions of a Supply Source<br />
When referring to a relay, an R is used. For a country, supply sources and<br />
their relays are:<br />
● The capital of a Major, friendly power.<br />
● A friendly city or town linked by rail, major river or sea to another<br />
friendly city.<br />
● Friendly railways connected to a friendly source (See C below). (R)<br />
● A major port linked to friendly ports through open seas. Minor ports<br />
supply 1 army only (see below)<br />
● Major rivers linking friendly cities or ports, unless one of the shores is<br />
under enemy control. (R)<br />
● A country’s HQ (and certain friendly HQs if they may cooperate) if<br />
they find themselves in a 2-region range from a valid supply source or<br />
relay. However, this HQ may only act as a relay for 1 HQ (no further<br />
HQs may be added to this link). (R)<br />
● The same for GHQ. (R)<br />
● A fortress is always in supply along with its garrison corps. It may<br />
supply one corps outside of its own garrison (and only in its own<br />
region).<br />
● A city (not a town) is a supply source for 1 corps in its region only,<br />
even if it is isolated.<br />
9.1.1 Definitions<br />
● An isolated city is a city that cannot establish communication with<br />
another of its allies’ cities through a “road” of regions which is blocked,<br />
either by enemy units, by enemy ZOC, or by forbidden regions.<br />
Looking at Enemy Stacks<br />
Looking at the contents of an enemy stack or enemy military counters is not<br />
permitted, except by successful aerial reconnaissance or by playing an event.<br />
Other than these 2 cases, the contents of a stack will only be discovered<br />
progressively in battle.<br />
● Supply may pass through a friendly strait.<br />
● A minor port linked to friendly ports through open seas may only<br />
supply one Army, and this one cannot be the Main Army of the front.<br />
(If it was, it ceases to be.) To supply more, it is necessary that the<br />
Armies in question be within reach of 2 minor ports at the same time.<br />
Example: In Northern France, the British Armies are supplied either by the<br />
2 minor ports of Calais and Dunkerque, or by the railroad leading to Paris.<br />
If one port is taken and the railroad cut off (ex. Arras), there is no more<br />
normal supply. Only one British Army may be supplied by the remaining<br />
minor port.<br />
9.1.2 Supply Distance<br />
Supply distance is 2 regions from a Source or a Relay, no matter what the<br />
weather or terrain of these regions might be (provided that they are<br />
passable by supplied units).<br />
To trace supply, it is necessary to begin from the unit to be supplied<br />
without counting the region it is in. Only the intermediate and supply<br />
(source or relay) regions are counted.<br />
The presence of an enemy unit or unbesieged enemy fortress blocks its<br />
region for supply.<br />
