Johann Georg Pforr drew just that - two powerful German horse (German as the entire territory of the Holy Roman Empire), one from Friesland and one from Holstein.

.German horses, bred with Spanish, Turkish, Barbs & Neapolitans were used in dressage, eg Cavendish talks about them in his famous equestrian work.

But from the military point of view we have more precise remarks  about thee horse written by general de Warnery - who said, that 
'[...]In a course of 600 paces, a good German horse, in condition, will gt before a Polish, Tatar, or other horse of that description: but if the course is continued  to a greater distance, the latter will regain its ground, leave the other behind, and continue in wind for a much longer time: and should the heavy horse be forced a little beyond his wind, he becomes insensible to the bit and spur, and loses all his activity, which is the reason that cuirassiers are never employed on any other occasion  than a regular battle[..].
