Beat me to it...

The whole POINT of the game is to choose terrain just as much as anything else. Sometimes backing people into mountains is a good thing, as it usually traps them there and forces them to fight (with you at a disadvantage. Although, if you're so big to have them cause flight, then, you're probably able to crush them).

And the key to mountain battles is, believe it or not, calvalry. In one particularly HORRIBLE map, every single unit except for my cavalry (all heavily armored, if I remember) were wasted tired while my cav were totally in the green.

So I did the unthinkable and was force to throw my calvalry into the battle headlong without any support to allow my troops time to rest and also to keep advancing (considering I nearly tripled my enemy in size)

Despite massive amounts of horse and foot archers, the strategy was the correct choice and I lost only 80-100 total men and destroyed nearly a thousand.
