I sent 1 general with 200 bows against 60 Boar and 140 Wolf Packleader. Round 1 resulted in my army killing 60 Boars and 7 Wolf Packleaders. Their 200 hits each killed one of my bows. At the end of round one, I have a general healthy against 133 Wolf Packleaders, he should kill one in round 2.
But there was no round 2. Is this a bug? He certainly "lost" the battle and returned to heal for 2 hours (Grim).
