The best I found was (for me at least!), was any high level foot with halberds /or pikes, first (as above) with
bowmen that fall back 20 paces as the cavlalry get near and then when they do tell the mounted usit to charge
from the right or left (as possible). Plus make sure they keep formation also being on a hill top helps to slow the
charge.
but then saying this, I tend to use mounted archers and heavy lancers for the most part, as most of my troops
are mounted.
