terrain types hmm i need to do a bit more reading on battles since so far i just do auto battles so i do not have to spent so much time to finish themDon't forget, terrain type is random, and some terrains heavily favor or hamper certain match-ups.
In early battles, when you get an unfavorable terrain, it doesn't mean as much, and so you generally don't fail, just suffer a little more casualties, maybe. As you progress, unfavorable terrain eventually rises to the level of making the difference between success and failure. Eventually, you get to the point where battles are so difficult that terrain differences are swamped by overwhelming enemy forces generally. This would appear to fit the observation of getting the sporadic fail in non-early battles.
by terain you do not mean silk, steel,...
