To answer my question though. Cavalry in SOW:W are all treated the same. Which is unfortunate because they really did have so many more ways of charging and operating than the generic random way this game will treat them.
But it is over all still better than most games I suppose. Just not the kind of full over haul of mechanics I was hoping for compared to SOW:G.
Permit me to disagree, it could exist many ways to charge (trot, in forager, gallop) some more used than others, but they were linked to the situation not to the cavalry type. Hussars of Napoleonic Wars were not the Hussars of Spanish Succession War, for training or for tactical use.
While light cavalry has a sure a different role out of battle as outpost, scouts, raids, pursuit, etc like described by De Brack in Light Cavalry Outposts, but in battle the use of cavalry of all the types is the same. Sure cuirasses (a late reintroduction also for the french) and big horses gave some advantage but is mainly a morale advantage.
It is good to remember the words of Ardant du Picq about the cavalry charge:
"
Cohesion and unity give force to the charge. Alignment is impossible at a fast gait where the most rapid pass the others. Only when the moral effect has been produced should the gait be increased to take advantage of it by falling upon an enemy already in disorder, in the act of fleeing. The cuirassiers charge at a trot. This calm steadiness frightens the enemy into an about face. Then they charge at his back, at a gallop.
They say that at Eckmühl, for every French cuirassier down, fourteen Austrians were struck in the back. Was it because they had no back-plate? It is evident that it was because they offered their backs to the blows.
Jomini speaks of charges at a trot against cavalry at a gallop. He cites Lasalle who used the trot and who, seeing cavalry approach at a gallop, would say: "There are lost men." Jomini insists on the effect of shock. The trot permits that compactness which the gallop breaks up. That may be true. But the effect is moral above all. A troop at the gallop sees a massed squadron coming towards it at a trot. It is surprised at first at such coolness. The material impulse of the gallop is superior; but there are no intervals, no gaps through which to penetrate the line in order to avoid the shock, the shock that overcomes men and horses. These men must be very resolute, as their close ranks do not permit them to escape by about facing. If they move at such a steady gait, it is because their resolution is also firm and they do not feel the need of running away, of diverting themselves by the unchecked speed of the unrestrained gallop, etc.
Galloping men do not reason these things out, but they know them instinctively. They understand that they have before them a moral impulse superior to theirs. They become uneasy, hesitate. Their hands instinctively turn their horses aside. There is no longer freedom in the attack at a gallop. Some go on to the end, but three-fourths have already tried to avoid the shock. There is complete disorder, demoralization, flight. Then begins the pursuit at a gallop by the men who attacked at the trot.
....
Because morale is not studied and because historical accounts are taken too literally, each epoch complains that cavalry forces are no longer seen charging and fighting with the sword, that too much prudence dictates running away instead of clashing with the enemy.
These plaints have been made ever since the Empire, both by the allies, and by us. But this has always been true. Man was never invulnerable. The charging gait has almost always been the trot. Man does not change. Even the combats of cavalry against cavalry today are deadlier than they were in the lamented days of chivalry.
The retreat of the infantry is always more difficult than that of the cavalry; the latter is simple. A cavalry repulsed and coming back in disorder is a foreseen, an ordinary happening; it is going to rally at a distance. It often reappears with advantage. One can almost say, in view of experience, that such is its rôle. An infantry that is repelled, especially if the action has been a hot one and the cavalry rushes in, is often disorganized for the rest of the day.
Even authors who tell you that two squadrons never collide, tell you continually: "The force of cavalry is in the shock." In the terror of the shock, Yes. In the shock, No! It lies only in determination. It is a mental and not a mechanical condition.
Never give officers and men of the cavalry mathematical demonstrations of the charge. They are good only to shake confidence. Mathematical reasoning shows a mutual collapse that never takes place. Show them the truth. Lasalle with his always victorious charge at a trot guarded against similar reasonings, which might have demonstrated to him mathematically that a charge of cuirassiers at a trot ought to be routed by a charge of hussars at a gallop. He simply told them: "Go resolutely and be sure that you will never find a daredevil determined enough to come to grips with you." It is necessary to be a daredevil in order to go to the end. The Frenchman is one above all. Because he is a good trooper in battle, when his commanders themselves are daredevils he is the best in Europe. (Note the days of the Empire, the remarks of Wellington, a good judge). If moreover, his leaders use a little head work, that never harms anything. The formula of the cavalry is R (Resolution) and R, and always R, and R is greater than all the MV squared in the world."
