Disappointingly easy

One could also randomize the battle a little to make it less "mechanical"

1. Every round one unit gets two extra speed points (difficult to run away from a unit forever).
2. After round 20 there is a 5% chance every round of the gods getting angry at the cowardly battle and they will send a lightening on one of the units of the largest remaining army.
3. After round 10 there is a 5% chance every round of a neutral unit entering the battle to help one of the sides. (depending on the race, location and so on).

This will not turn a battle upside down, but it will make things a bit more interesting in my opinion.
