Basically using RP to resolve a conflict on a tactical-local level. The players send me their battleplan, and either I send each sections of the battle story to write, usually sections where they can glorify themselves, or they themselves volunteer sections and I help edit it so it fits.
Anyway, this seems closer to what you actually want; a quick war against an NPC, fought with several RP'ed posts and with moderator consensus. Am I right?
Also, Rebel Stats are currently: 2 Warriors, 3 Militia, a total of 5 thousand dudes scattered around the other town you didn't purge. They can recruit another thousand militia to replace losses every 4 months. Go get'em.
