Something very odd about this scenario. Mini-Tournament results favour the Uesugi 4-1. Moreover, there is virtually no reason for the Oda to attack the Uesugi, simply crossing in force is the best option. Combat will mostly favour the Uesugi troops, so why attack and risk battle back?
Perhaps my least favourite new scenario.
