heh 90% of that army was archers? I take it that explains why you've massed all your cavalry into one huge armoured fist? I do that many times, saved me more times than I can recall.
I haven't really had any MAJOR battles in MTW2 yet unfortunately, I was playing as the English and I fought in a similar sized battle to that with the French but that's about it. I had a crusading army heading round to attack the Holy Land but the Crusade was successful by the time it got there so I had a packed army in the Mid East with nothing to do, so I razed some Egyptian cities, I had expected a huge battle there but the Egyptians were most certainly MIA, only a few units in the cities
