Escape

imo, they could have avoided reducing the number of neutrals; +1 knowledge would have been enough. One battle is simply random; it depends on which arena appears and what the morale of the enemies will be, but in the first version, after it, 5 zombies were raised, and the swordsmen could break through the castle more easily.

although, no, it's impossible to break through with three zombies, even with 2 resources, so I'll just play with my saved games with the pre-set knowledge, rather than stressing myself out.
