You would have had 50,000 rabble. They would kill possibly about 10k of my troops, but probably less if I had the Mishfardens do a rear surprise attack. Also, I didn't expect for them to win a fight. If you had agreed, Wolf would have just been taken into questioning and not threatened. If he was found guilty and he plead guilty Solterra would probably have just charged him for like 10k bullis. If Wolff rejected, as expected, doesn't matter. They served as a direct threat to Wolff and would make a last ditch effort to kill as many of his people and property as possible. Their job was successful. 

Also, So Boerd, that's okay. Solterra would have eventually just threw fire at your villages and sent the Mishfardens in to rape and pillage, killing morale
