Amazing plot twist, loved it. And not to detract from the thread, but I actually was betrayed by a fairly long serving general in ROTS just prior to the battle. made for an interesting and fun fight, but said traitor survived. Until I promoted the captain who replaced him and sent the new General to finish him off.
The reason I point this out is when it happened I was completely surprised, and I actually also thought.. "well crap, I bet this his probably how Haronobu felt too." Yep, even during my own campaign, set in an earlier timeframe, I drew parallels to your AAR.
