I had a long rebuttal but i accidently closed out of the browser so ill keep it short because the blackhawks are playing.
First off, you cant make this game as realistic as on the battlefields of europe. You cannot even come close.
My main concern is something that can be made more realistic. The cavalry in this mod are useless after one charge because they become tired and never recover from being tired.
The walking is also very slow, i think it should be more of a trot to represent this;
On the battlefield the cavalry would advance
against the enemy in either slow, medium or fast pace:

walk - approx. 100 m/minute
trot - approx. 200 m/minute

gallop - approx. 300 and more m/minute
If you want to make the game more realistic i suggest you incorperate this fact into the mod (i dont even know if its possible)....Expert on cavalry,
Ardant du Picq, stated (with some exaggeration, just to make the point) that 49 of 50 one side hesitated, disordered and fled before contact was made. Approx. 75 % of the time this will happen at a distance, before they can see each other's eyes. Officer of the Grand Duke Constantine Uhlans,
Faddei Bulgarin, wrote that only those who never actually participated in cavalry battle talk about two opposite masses or lines of cavalry clash with each other and fight until one side is annihilated.
Bulgarin wrote that it was not so, usually one side attacked and the other retreated, then the victor and pursuer was counterattacked by second line or reserves and overthrown and pursued in its turn. Already in 18th Century,
Mirabeau wrote that "veteran cavalry officers have told us that when two bodies of cavalry charge one another, it almost always happens that one party flees before the other can meet it. Saber blows are dealt only during the pursuit."
Often they will get closer. Even in these few cases where both sides colided, there was no shock at full speed, but a halt face to face and then an engagement.
I was simply looking for an answer to my problem, how to mod the game into making cavalry recover from fatigue at an improved rate. I am not trying to bad mouth the game because i think its the best mod on for napoleon. This is the
only thing that is bugging me. Now will someone please help me?
