Actually that screenshot is from a while ago and had totally forgotten about it. I just found it and went "WHAT?!"
It's too long ago to remember exact details which is why I use common terms to describe it, but if I'm right they were peasants, spearmen, archers, and two cavalry. If it weren't for that hill top and that narrow passageway + the flank route next to it I would've been overwhelmed on normal ground.
