Why are you attacking uphill anyway?

Surely it would be better to approach from a different angle, or lure the enemy off that position so you at least fight on relatively even terrain...

I always avoid attacking uphill if I can help it, if I have to take a detour to bring the fight to the enemy and reach the top of the hill, I will do so.

If I have no choice but to fight on a hillside I will do so on the most gentle slope on the hill and I will always lead with an expendable unit of Mercs to act as a speedbump against the enemy charge...

Thats what Mercs are for to die well and be disbanded afetr the battle!
