Thanks for correcting me, I never knew that before.

The only reason i said that was because the majority of the times in the past when ive seen this happen it was down to two full scale armies meeting eachother face to face, This was the only possible reason for me to think in that way.

I still think that on medieval its not as prolific as it was on Rome, And if there is a way of changing it, Increasing it, Please could you let me know.
