I promise not to derail this thread, but are you talking about the most recent war involving Fronen and OG? I remember that OG swooped in and stole Yipinalke and dropped militia like a boss, not the other way around. And yes, it worked very well for them. 
No before that, back when the OG/NG civil war was ending. That's how Fronen got the region in the first place... *digs through distant memories* Neo Grehk was doing good against Old Grehk, they were pretty evenly matched, then a rebellion in Neo Grehk led to all the lords switching allegiance to Old Grehk... save one, the lord of Yipinalke, who joined Fronen, then a few hours later joined Old Grehk. Fronen used that as an excuse to establish a claim, quickly declare war and take the region, dropping insurmountable amounts of militia. It wasn't until much later that they lowered their guard and OG returned the favor.
Edit: four days later, not hours.
