supply from allies minor country capital

[Courtenay]

I had always thought that if a cooperating unit could trace supply, then my unit could trace supply, based on the cooperation rule, 18.3:

Apart from control of hexes, reorganization, reinforcement and activities limits, units which co-operate act as if they were from the same country (they may move and fight together, etc.).

Since supply was not in the "apart" list, I had thought supply was the same for cooperating countries. I just found an exception: Minor country capitals.

A secondary supply source for a unit is:[...]
The capital city of a minor country controlled by the unit’s major power;

It does not say that a secondary source is a minor capital controlled by a cooperating major power. Is this correct? Do minor country capitals of minor countries controlled by a cooperating power not serve as secondary supply sources? If the minor country capital were conquered, rather than belonging to an ally, then it would count as a supply source, which strikes me as strange, if an ally's capital doesn't.

I ask because I just discovered that a CW unit in a Free French Algiers is out of supply, although I can trace by rail back to Casablanca, and from there to England. Is this correct? If so, this is another rule that I have been playing incorrectly for many years.

Captured minor country capitals are different from aligned minor country capitals. The former can be used as a secondary/tertiary supply source by all minor countries aligned to the major power. The latter can only be used as a secondary/tertiary supply source by the major power itself. Note that an aligned capital is a primary supply source for units belonging to the minor country itself. Also, a captured capital is a primary supply source for any of its territorial units controlled by the major power that conquered the minor country.

I believe that if France and the Commonwealth cooperate, then the capitals of minor countries aligned to or conquered by France should be potential secondary/tertiary supply sources for the Commonwealth. If they don't, they aren't.

This was a major headache to code. Here are my in-line notes and variable lists for keeping track of this for any country that might have units on the map. The supply paths are also important for determining which units can be supplied. Coop paths include a cooperating major power's supply source in the path. Those can be primary, secondary, or tertiary. Coop paths can't be used by units belonging to aligned minor countries (e.g., Rumanians can't use Italian supply sources). Mixed paths include both aligned minor country and cooperating major power supply sources, so they can only be used by the major power that controls the minor and cooperates with the other major powers (e.g., a German unit tracing through a Rumanian HQ to an Italian primary supply source).

It does not say that a secondary source is a minor capital controlled by a cooperating major power. Is this correct? Do minor country capitals of minor countries controlled by a cooperating power not serve as secondary supply sources? If the minor country capital were conquered, rather than belonging to an ally, then it would count as a supply source, which strikes me as strange, if an ally's capital doesn't.

This is correct as to the way it works. FREX CW-controlled Cairo is not a secondary supply source for the U.S., but CW-conquered Tripoli is.
