Louis the XIV

I'm not sure, you could check the function itself and find out, probably some where in a C++ file in the DLL, but that might take too much time. So you could just try different numbers and see the outcome, for example make the numbers be (26, 26, 26, 6) and then change the 6 to 26, if anything changes you will know that the last number affects it.

Thank, but I figured out another way to have an event from france to vichy france

I'll try, but I don't really understand what exactly type of unit you want.
Arquebusier, musketman, rifleman?
I also don't know what Zagończyk is so could you please be more specific?

You don't have to do Zagończyk
Piechota wybraniecka-Arquebusier
Lisowczycy-knight
Piechota wybraniecka(version sword)-Maceman
Piechota wybraniecka(version pikeman)-pikeman
Piechota wybraniecka(version dragoon)-cavalery
Nobleaman-Swordsman
pelase on Civ4

The main issue is that I'd not be able to test it, which would make this a real pain in the rear.

I also can't plug the code elsewhere. At the moment the event is tied to the building of an improvement. It would require to move the code to... er... onBeginPlayerTurn instead,

which is not that recommended, since this will run often. Then I need to keep track of the turn, then check all the plots within the players territory, if there's a fort, if there's no enemy unit in it, and then spawn the militia. So this requires a bit more logic, which I can't test :/, sorry :(.

Oh I understand.
